Open Source ChromeOS Markdown Editors

MiaoYan is a lightweight, native Markdown note-taking app for macOS, built to give programmers and writers a fast, distraction-free environment for text. It is fully local-first, meaning your notes live as plain Markdown files on your machine rather than in a proprietary cloud, which appeals to privacy-conscious users. The app focuses on a minimalist three-column layout (folders, note list, editor) with syntax highlighting, dark mode, and typography tuned for Chinese and English writing. Beyond basic editing, MiaoYan supports presentation and PPT-style modes, letting you turn Markdown documents into slide-like views directly inside the app. It also adds power-user features like automatic document typesetting, internal links, LaTeX math, Mermaid and PlantUML diagrams, and Markmap mind-map rendering. Under the hood, it is implemented in Swift as a native macOS application, which keeps it snappy and lighter than Electron-based note apps.

Alexandrie is a fast, modern, and open-source web application for taking and organizing notes using an extended Markdown syntax, designed for students, creators, and knowledge workers. It offers a structured note-taking experience with support for workspaces and categories, making it easy to organize large repositories of information intuitively. The application runs as a responsive web interface that works online or offline, with search and export features that help users retrieve and reuse their content effectively. Built with a clear focus on productivity, Alexandrie includes support for custom storage backends like S3-compatible services or local file systems via Docker Compose setups. Its extended Markdown syntax lets users embed rich content, multimedia references, and structured blocks that go beyond plain text, while the sleek UI encourages distraction-free writing and review.

Markdown-Resume provides a simple, portable way to author a résumé using plain Markdown and then render it into a clean, professional layout. The idea is to keep content and presentation separate: you write experience, skills, and education in text, and the tooling handles typography. This approach makes version control, diffing, and iterative edits straightforward, which is especially useful when tailoring résumés to different roles. The repository typically includes a theme or template along with scripts or instructions for producing HTML and PDF outputs. Because the source is Markdown, it is easy to localize, reorder sections, or automate updates via a CI workflow. It’s a pragmatic balance of designer-friendly output and developer-friendly authoring.

kodeWeave is a realtime coding playground for HTML, CSS and Javascript. Similar to JSFiddle and JSBin, but kodeWeave was made to work offline but also as a prototyping application to build applications for desktop operating systems while on mobile devices. (PhoneGap Build is recommended for mobile devices) kodeWeave similar to jsfiddle, jsbin, dabblet, liveweave, codepen, cssdeck, cssdesk, tinkerbin, d3 playground, plunker and pastebin, but allows you to export your web app as a desktop and/or chrome application.

AudioNotes is an application (or proof-of-concept) that likely combines audio recording or playback with note-taking or annotation functionality — enabling users to record voice or audio and attach textual or timestamped notes, making it ideal for lectures, interviews, meetings, or personal memos. Such a tool offers a more expressive and flexible way to capture and revisit information: instead of just typed notes or raw audio, users get both audio context and structured notes. As an open-source repository, AudioNotes provides developers or power users the opportunity to customize how audio is captured, stored, annotated, and replayed — e.g. adding playback speed control, export to standard formats, or synchronization between notes and audio timeline. It may support simple UI for starting/stopping recordings, writing or editing notes, and navigating through recorded sessions.

Flatdoc is a tiny JavaScript library that builds a documentation site directly from Markdown files, without requiring a server-side engine or static site generator. Point it at a Markdown source and it fetches, parses, and renders content into a ready-to-browse doc layout in the browser. It autogenerates a navigation sidebar from headings, supports anchors, and provides a clean default theme that’s easy to restyle. Because it runs client-side, it’s great for small projects, GitHub-hosted docs, or internal references where you want “drop-in” documentation with minimal setup. The library’s footprint and API are intentionally modest, making it simple to customize templates, typography, or color schemes. For teams who value instant docs from a README or single Markdown file, Flatdoc remains a practical, dependency-light choice.
