Optic
Generate, Diff, and Test OpenAPI Descriptions
Vizualize API changes to improve the quality of reviews. Test API changes to ensure nothing bad slips through. OpenAPI diffs are difficult to read. Because these files contain references, small changes can have a large effect on your API. Linters can not check for backward compatibility or enforce versioning and deprecation policies. Optic adds a visual changelog to every Pull Request that makes it easy to see exactly what API changes have been proposed. Optic tests each set of API changes in CI, making it more powerful than a linter. Our built-in checks will help any team ship a more reliable API. OpenAPI diffs are very difficult to review, comprehend and give feedback on. Optic’s changelogs are easy to understand allowing anyone (even non-developers) to participate in review. Optic goes beyond linting OpenAPI, it lets you write test about each set of API changes. We also make it easy to share your API standards. -

ktlint
An anti-bikeshedding Kotlin linter with built-in formatter
No configuration, which means no decisions to make, nothing to argue about and no special files to manage. While this might sound extreme, keep in mind that ktlint tries to capture (reflect) official code style from kotlinlang.org and Android Kotlin Style Guide (+ we respect your .editorconfig and support additional ruleset|s). Built-in formatter. So that you wouldn't have to fix all style violations by hand. Customizable output. plain (+ plain?group_by_file), JSON, HTML and check style reporters are available out-of-the-box. It's also easy to create your own. A single executable jar with all dependencies included. ktlint is a single binary with both linter & formatter included. All you need is to drop it in (no need to get overwhelmed while choosing among dozens of code style options). -

Haskell Dockerfile Linter
Dockerfile linter, validate inline bash, written in Haskell
A smarter Dockerfile linter that helps you build best practice Docker images. The linter parses the Dockerfile into an AST and performs rules on top of the AST. It stands on the shoulders of ShellCheck to lint the Bash code inside RUN instructions. You can run hadolint locally to lint your Dockerfile. You can download prebuilt binaries for OSX, Windows and Linux from the latest release page. However, if this does not work for you, please fall back to container (Docker), brew or source installation. Configuration files can be used globally or per project. -

JavaScript Standard Style
JavaScript style guide, linter, and formatter
JavaScript Standard Style is a JavaScript style guide with linter and automatic formatter. It’s the simple, easy, fuss-free way to get a consistent style in your project. No more hundred-line style configuration files for every module/project; no more messy or inconsistent code; and no more wasting time sending code back and forth between reviewer and contributor. With Standard, your code is automatically formatted, no configuration necessary. With Standard, code clarity and community conventions is paramount. This may not make sense to all projects or development cultures, but does make a lot of sense for open source projects where setting up clear, automated contributor expectations makes a project healthier. -

Joker
Small Clojure interpreter, linter and formatter
Joker is a small interpreted dialect of Clojure written in Go. It is also a Clojure(Script) linter. Send HTTP requests, read and parse JSON, work with file system, start external processes etc. Checks for syntax errors, function arity mismatches, unresolvable symbols, unused namespaces, vars, bindings and much more. Joker uses .joke filename extension. Normally exits after executing the script, unless --exit-to-repl is specified before --file <filename> in which case drops into the REPL after the script is (successfully) executed. (Note use of --file, in this case, to ensure <filename> is not treated as a <socket> specification for the reply.) Our goal is to be suitable for scripting (lightweight, fast startup). This is something that Clojure is not good at and my personal itch I am trying to scratch. Also, to provide some tooling for Clojure and its dialects. Joker has linter mode which can be used for linting Joker, Clojure and ClojureScript code. -

Jsonnet
Jsonnet, the data templating language
A data templating language for app and tool developers. Eliminate duplication with object-orientation or use functions. Integrate with existing / custom applications. Generate JSON, YAML, INI, and other formats. The name Jsonnet is a portmanteau of JSON and sonnet, pronounced "jay sonnet". It began life early 2014 as a 20% project and was launched on Aug 6. The design is influenced by several configuration languages internal to Google, and embodies years of experience configuring some of the world's most complex IT systems. Jsonnet is now used by many companies and projects. Jsonnet is not an official Google product (experimental or otherwise), it is just code that happens to be owned by Google. Jsonnet is open source (Apache 2.0), familiar syntax, reformatter, linter, editor & IDE integrations, and formally specified. -

Pylint
It's not just a linter that annoys you!
Pylint is a static code analyzer for Python 2 or 3. The latest version supports Python 3.7.2 and above. Pylint analyses your code without actually running it. It checks for errors, enforces a coding standard, looks for code smells, and can make suggestions about how the code could be refactored. Projects that you might want to use alongside pylint include flake8 (faster and simpler checks with very few false positives), mypy, pyright or pyre (typing checks), bandit (security-oriented checks), black and isort (auto-formatting), autoflake (automated removal of unused import or variable), pyupgrade (automated upgrade to newer python syntax) and pydocstringformatter (automated pep257). Pylint isn't smarter than you: it may warn you about things that you have conscientiously done or checks for some things that you don't care about. During adoption, especially in a legacy project where pylint was never enforced. -

SublimeLinter-eslint
This linter plugin for SublimeLinter provides an interface to ESLint
This linter plugin for SublimeLinter provides an interface to ESLint. It will be used with "JavaScript" files, but since eslint is pluggable, it can actually lint a variety of other files as well. SublimeLinter will detect some installed local plugins, and thus it should work automatically for e.g. .vue or .ts files. If it works on the command line, there is a chance it works in Sublime without further ado. Make sure the plugins are installed locally colocated to eslint itself. T.i., technically, both eslint and its plugins are described in the very same package.json. Configuration of the plugins is out-of-scope of this README. Be sure to read their README's as well. (If you just installed a plugin, without proper configuration, eslint will probably show error messages or wrong lint results, and SublimeLinter will just pass them to you.) -

Ultracite
A highly opinionated, zero-configuration linter and formatter
Ultracite is a highly opinionated, zero-configuration linting and formatting preset designed primarily for modern JavaScript/TypeScript codebases. It is built on top of the Biome toolchain (written in Rust) and aims to deliver sub-second performance so that formatting and linting feel seamless, even on large projects. Because it comes pre-configured with sensible defaults for frameworks like React and Next.js, developers can adopt it with minimal setup—simply run npx ultracite init and start coding. The project emphasizes type-safety and best practices, enforcing stricter rules out of the box so that unsafe or sloppy patterns are discouraged. It also positions itself as “AI-ready,” meaning it’s designed to integrate smoothly into workflows where AI code generation (e.g., from Copilot, Claude Code, etc) is involved, ensuring consistent style across team-written and machine-written code. -
13
lint-staged
Run linters on git staged files
Run linters against staged git files and don't let anything slip into your code base! Linting makes more sense when run before committing your code. By doing so you can ensure no errors go into the repository and enforce code style. But running a lint process on a whole project is slow, and linting results can be irrelevant. Ultimately you only want to lint files that will be committed. This project contains a script that will run arbitrary shell tasks with a list of staged files as an argument, filtered by a specified glob pattern. Linter commands work on a subset of all staged files, defined by a glob pattern. lint-staged uses micromatch for matching files. The concept of lint-staged is to run configured linter tasks (or other tasks) on files that are staged in git. lint-staged will always pass a list of all staged files to the task, and ignoring any files should be configured in the task itself. -

tslint-to-eslint-config
Converts your TSLint configuration to the closest possible ESLint
Converts your TSLint configuration to the closest reasonable ESLint equivalent. The tslint-to-eslint-config command reads in any existing linter, TypeScript, and package configuration files, then creates an .eslintrc.js result based on them. For any TSLint rules with corresponding ESLint equivalents, those equivalents will be used in the new configuration. TSLint rules without ESLint equivalents will be wrapped with eslint-plugin-tslint. If passed without arguments, respects the excludes, files, and includes in your TypeScript configuration. -
15
CSSLint
Automated linting of cascading stylesheets
CSSLint is an open-source CSS code quality tool originally written by Nicholas C. Zakas and Nicole Sullivan. A lint tool performs static analysis of source code and flags patterns that might be errors or otherwise cause problems for the developer. CSSLint is a tool to help point out problems with your CSS code. It does basic syntax checking as well as applying a set of rules to the code that look for problematic patterns or signs of inefficiency. The rules are all pluggable, so you can easily write your own or omit ones you don't want. You can integrate CSSLint into your favorite IDE to make checking your CSS code quality easy. In fact, some IDEs already have CSSLint built-in. Once you're familiar with the CSSLint command-line interface, the next step is to integrate it into your build system. -

Sorted imports, dangling commas for cleaner commit diff. Reasonable defaults, best practices, only one-line of config. -
18
esprint
Fast eslint runner
esprint (pronounced E-S-sprint) speeds up eslint by running the linting engine across multiple threads. esprint sets up a server daemon to cache the lint status of each file in memory. It uses a watcher to determine when files change, to only lint files as necessary. It also has a CI mode where it does not set up a daemon and just lints in parallel. In order to use esprint, first place an .esprintrc file in the root directory your project. This is similar to a .flowconfig if you use flow types. The .esprintrc file describes which paths to lint and which paths to ignore. You can also override the port to start the background server on. esprint will find the root of your project automatically and lint the whole project. In default mode, esprint will start a background server to watch source files and cache lint results in memory. -

Bootlint
HTML linter for Bootstrap projects
Bootlint is a tool that checks for several common HTML mistakes in webpages that are using Bootstrap in a fairly "vanilla" way. Vanilla Bootstrap's components/widgets require their parts of the DOM to conform to certain structures. Bootlint checks that instances of Bootstrap components have correctly structured HTML. Optimal usage of Bootstrap also requires that your pages include certain <meta> tags, an HTML5 doctype declaration, etc.; Bootlint checks that these are present. Bootlint assumes that you are using Bootstrap's default class names in your webpage, as opposed to taking advantage of the "mixins" functionality of Less or Sass to map them to custom class names. If you are using mixins, Bootlint may report some false-positive warnings. However, there are some Bootlint checks that are applicable even if you are using mixins pervasively. -
21
Ruff
An extremely fast Python linter, written in Rust
An extremely fast Python linter, written in Rust. Ruff aims to be orders of magnitude faster than alternative tools while integrating more functionality behind a single, common interface. Ruff can be used to replace Flake8 (plus dozens of plugins), isort, pydocstyle, yesqa, eradicate, pyupgrade, and autoflake, all while executing tens or hundreds of times faster than any individual tool. Ruff is extremely actively developed and used in major open-source projects. Ruff can be configured through a pyproject.toml, ruff.toml, or .ruff.toml file (see: Configuration, or Settings for a complete list of all configuration options). Ruff supports over 500 lint rules, many of which are inspired by popular tools like Flake8, isort, pyupgrade, and others. Regardless of the rule's origin, Ruff re-implements every rule in Rust as a first-party feature. -

babel-eslint
A wrapper for Babel's parser used for ESLint
babel-eslint allows you to lint ALL valid Babel code with the fantastic ESLint. ESLint's default parser and core rules only support the latest final ECMAScript standard and do not support experimental (such as new features) and non-standard (such as Flow or TypeScript types) syntax provided by Babel. babel-eslint is a parser that allows ESLint to run on source code that is transformed by Babel. You only need to use babel-eslint if you are using Babel to transform your code. If this is not the case, please use the relevant parser for your chosen flavor of ECMAScript (note that the default parser supports all non-experimental syntax as well as JSX). ESLint allows for the use of custom parsers. When using this plugin, your code is parsed by Babel's parser (using the configuration specified in your Babel configuration file) and the resulting AST is transformed into an ESTree-compliant structure that ESLint can understand. -
23
commitlint
Lint commit messages
commitlint checks if your commit messages meet the conventional commit format. commitlint helps your team adhere to a commit convention. By supporting npm-installed configurations it makes sharing of commit conventions easy. We're not a sponsored OSS project. Therefore we can't promise that we will release patch versions for older releases in a timely manner. If you are stuck on an older version and need a security patch we're happy if you can provide a PR. If something in between fails (like a new packages was added and needs to be published for the first time but you forgot) you can use lerna publish from-package to publish anythign that has not been published yet. We identify ease of adoption and developer experience as fields where there is room and need for improvement. The items on the roadmap should enhance commitlint regarding those aspects. -

Automatically format code. Just run gts fix and say goodbye to messy or inconsistent code. Catch style issues & programmer errors early. Save precious code review time by eliminating back-and-forth between reviewer & contributor. Opinionated, but not to a fault. We recommend you use the default configuration, but if you need to customize compiler or linter config, you can. Under the covers, we use eslint to enforce the style guide and provide automated fixes, and prettier to re-format code. -
25
prettier standard
Formats with Prettier and lints with ESLint+Standard!
Formats with prettier (actually prettierx) and lints with eslint preconfigured with standard rules. You don't have to fix any whitespace errors and waste time configuring eslint presets. Prettier-standard is best used with the prettier-standard --lint command which formats and lints all non-ignored files in the repository.
Guide to Open Source Linters
An open source linter is a type of software that helps developers write better quality code. It is designed to detect coding errors, junk code, and other potential problems before the code is compiled. This can help developers spot mistakes quickly and make sure their projects are up to standards.
Open source linters are available for a variety of different programming languages and development tools, including JavaScript, HTML, CSS, Python, Ruby on Rails, and many more. Linters can also be used to check the formatting of code files as well as ensuring they follow established coding conventions. For example, they may remind you not to use spaces instead of tabs or vice-versa.
The main advantages of using an open source linter over commercial options are cost and flexibility. Since the software is free and open source under most licenses (typically MIT), anyone can access it without having to buy or pay for it separately. Additionally, since anyone has access to the source code itself, users have much more control over how they use the tool than with commercial options which may have features locked down or limited in some way.
Additionally, open source linters tend to receive more frequent updates than commercial options due in part to community contributions from experienced developers who want their suggested changes implemented into the project. The larger contributor base also means there are more resources dedicated towards bug fixes should any arise in addition to increasing overall stability of the project itself.
All in all, open source linters are a great way for developers to ensure their code is of the highest quality. They're free and flexible, plus can be used for any programming language or development tool. With their frequent updates and bug fixes, open source linters make it easier than ever before to write clean, secure code.
Features Offered by Open Source Linters
- Syntax Checking: Open source linters check code for syntax errors, ensuring that the code is written correctly. This improves the accuracy of code while minimizing debugging time.
- Static Analysis: Many open source linters provide static analysis capabilities, which identify issues in the code that may not be detected by traditional debugging techniques. Static analysis can detect problems such as inefficient algorithms or memory leaks.
- Code Formatting: Open source linters can help maintain a consistent coding style across projects and teams by checking for common formatting mistakes like incorrect indentation or missing semicolons. By improving readability, this feature makes it easier to collaborate on projects with multiple developers.
- Automated Refactoring: Open source linters can automatically refactor code to adhere to best practices or quickly clean up an existing project. This helps reduce the amount of time spent manually refactoring each piece of code and ensures consistency throughout the project.
- Diagnostic Output: Many open source linters come packaged with diagnostic output options that provide detailed explanations about why certain issues are flagged in the code base. With more comprehensive error messages and suggested fixes, debugging becomes much easier and faster without compromising quality.
- Plugins: Open source linters often come packaged with a large library of plugins that can be used to extend its functionality. Developers can use these plugins to tailor the linter’s behavior, add additional features, and customize it to fit their specific needs.
What Types of Open Source Linters Are There?
- JavaScript Linter: A JavaScript linter is a type of open source linter that checks for errors in JavaScript code. It also helps to enforce coding conventions and best practices, such as avoiding using global variables and keeping variable names consistent across the program.
- CSS Linter: A CSS linter is used to check your cascading style sheets (CSS) for any errors, typos, inconsistencies or coding violations. It can also help detect possible issues with your design before they become an issue on the web page.
- HTML Linter: An HTML linter is an open source tool that validates the syntax of HTML documents and flags any errors or typos within them. This helps to make sure that all content displays properly in a web browser.
- YAML Linter: A YAML linter is an open source tool used to verify the correctness of files written in YAML (Yet Another Markup Language). It checks for both syntax errors and structural problems such as missing properties, invalid types and more.
- XML Linter: An XML linter is a type of open source software which checks for proper structure and syntax in XML documents against an extensible markup language (XML) schema definition language (XSD). This can help developers spot potential bugs early on in their development process.
- JSON Linter: A JSON linter is an open source software which checks for errors in JavaScript Object Notation (JSON) files. It can detect missing braces, improper formatting and other issues that could cause problems with how the data is interpreted.
- PHP Linter: A PHP linter is a type of open source software designed to help developers locate and fix any issues within their codebase. It checks for syntactical errors, basic standards violations and more; helping to identify potential problems before they become serious bugs down the line.
Benefits Provided by Open Source Linters
- Increased Reliability: Open source linters help reduce the chances of introducing errors and bugs into code by verifying its correctness against a set of predefined rules. By consistently checking for errors, open source linters ensure that code is written to a consistent standard throughout the development process.
- Improved Developer Productivity: Developers can quickly identify mistakes in their code and fix them without having to manually go through every line. This helps save time and effort during coding, which can be used instead to focus on other aspects of product development. Additionally, by reducing the possibility of introducing errors, developers can avoid costly rework down the line while still making sure their code meets quality standards.
- Enhanced Code Maintainability: An open source linter creates an environment where any changes made to the codebase are kept consistent with previously established conventions. This helps make it easier for future developers (or yourself at a later date) to maintain your codebase and quickly understand how it works without being bogged down by inconsistencies or unfamiliar conventions or styles.
- Automated Corrections: Most open source linters feature automated corrections that help auto-format your code so that it adheres to predefined conventions. This helps promote faster development cycles since developers won't have to manually reformat their code each time they make a mistake or come back after taking a break from programming for too long. Additionally, automated corrections ensure consistency across different pieces of your project's code architecture, helping prevent subtle but important issues arising from differences in formatting styles between various components and people working on them.

How To Get Started With Open Source Linters
Getting started with using open source linters is easy and can help to improve the quality of code written. The first step is deciding which linter is best for a given language or framework. Different languages will have different types of linters, so make sure to pick one that is specifically designed for the language you are working with.
Once you’ve chosen a linter, download it, if necessary, and install it on your workstation. You may need to set up configuration files or other settings specific to the linter tool before it’s ready to use. Depending upon the type of linter, there may be options available that allow users to customize their usage experience by fine-tuning output messages or assigning text colors based off of warnings and errors displayed in the output logs. Some popular linters like ESLint even provide an interactive setup process which allows users select recommended rules and plugins generated specifically for their project type right within the installation wizard.
Now that you have your linter installed, you can start running it against existing codefiles in order to check for any potential issues or bugs contained within them. Many tools are command line based. This means they must be run from a terminal window such as Powershell, Command Prompt, etc. Just input the correct command based on your chosen configuration settings in order review data gathered by the linter results page by page or file by file. You can also set up automation processes that continuously evaluate and monitor code quality throughout development cycles as changes are made and features added/removed from existing projects over time. This way bugs get caught quickly early on during testing phases instead at production stage when issues affect user experience negatively later down the road.
Finally, depending on how much customization was done prior, debugging issues found via analysis from configurable rulesets can range from relatively simple fixes all the way up more complex resolutions requiring further inspection into problem areas. Remember: consult online documentation provided by each library producer first before making any major modification decisions especially when dealing with underlying architecture elements like syntax format structure. With that said, the open source community is full of helpful resources like forums and wikis packed with previously shared solutions useful for quick resolution of commonly encountered problems.
In short, getting started with an open source linter is easy, and it can greatly improve the quality of code written. It only takes a few minutes to set up and configure one, but the payoff can be huge in terms of debugging time saved down the road.
