Open Source Erlang Software for BSD

30-days-of-elixir is an educational repository created by Josh Adams (seven1m) designed to teach the fundamentals of the Elixir programming language through a structured, daily learning approach. The project provides a series of exercises and examples meant to guide learners from the basics of Elixir syntax to more advanced functional programming concepts. Each day introduces new material in a concise and practical format, encouraging hands-on experimentation and gradual mastery of the language. The content covers essential topics such as pattern matching, recursion, data structures, processes, and message passing—core principles that define Elixir’s design. This incremental learning format allows developers to build confidence and understanding while maintaining consistent progress. As one of the early and influential resources in the Elixir community, 30-days-of-elixir remains a valuable guide for self-learners and newcomers to the functional programming paradigm.

MQTT client is designed for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts and implements MQTT protokol versions 3.1 and 3.1.1. The client is written in Erlang and tested with MQTT servers like Mosquitto and RabbitMQ.

CloudI is an open-source private cloud computing framework for efficient, secure, and internal data processing. CloudI provides scaling for previously unscalable source code with efficient fault-tolerant execution of ATS, C/C++, Erlang/Elixir, Go, Haskell, Java, JavaScript/node.js, OCaml, Perl, PHP, Python, Ruby, or Rust services. The bare essentials for efficient fault-tolerant processing on a cloud!

OSDL: Object-oriented Simple DirectMedia Layer. OSDL is a high level open source (LGPL/GPL) portable multimedia library, built upon Sam Lantinga's SDL (http://www.libsdl.org). Its goal is to provide a high level C++ framework to ease game development.

MQTT server is designed for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts and implements MQTT protocol versions 3.1 and 3.1.1. The server is written in Erlang as OTP application.

C, Python, Lua, and Erlang libraries for manipulating APEv2 tags.

Erlang OPENGL/SDL api and utilities.

Implementation of Aspect Oriented Programming (AOP) for Erlang. The AOP weaver is running against a target set of source files and controlled by aspect definitions. The weaver is implemented as a parse transformation function of Erlang compiler.

The Bluetail Ticket Tracker (BTT) is a system for creating, storing and keeping track of tickets. BTT can also store customer info and mail, as well as general information structures (e.g FAQ).

A Python implementation of Erlang concurrency primitives. Erlang is widely respected for its elegant built-in facilities for concurrent programming. This package attempts to emulate those facilities as closely as possible in Python.

The Ceylan library is a Free (LGPL/GPL) General-purpose Portable Open Source C++ Library, offering frameworks and abstractions of lower-level layers to ease software development.

EPSI (Erlang Publish-Subscribe Infrastructure) is an Erlang implementation of a distributed infrastructure providing a content-based publish-subscribe service to its clients.

ERESYE means ERlang Expert SYstem Engine. It is a library to write expert systems and rule processing engines using the Erlang programming language. It allows to create multiple engines, each one with its own facts and rules to be processed.

ESense - Erlang "IntelliSense" for Emacs

Eddie acts as a high availability WAN and LAN clustering tool for web servers (including Apache). It provides load balancing at two levels (DNS and LAN), failover redundancy, and admission control to maintain quality of service levels.

Simple SOAP connector for Erlang/OTP. Compatible with SOAP 1.1 and 1.2. Currently supports XSD schema for service definition but no WSDL.

The ERDialog project offers a simple browser framework for small projects written in Erlang. Written applets include a bittorrent client, address book, text editor, AI experiments and graphics and music applications.

Resource pool project is written in Erlang as a tiny library. The goal of the tool is reduce the overhead of creating new resources by reusing of the same resources among multiple processes. Achieving result is better performance and throughput. The resource pool was inspired by Java Apache's commons pool and adopts API and main principals from this project. Database connection is most popular example for pooling resource.

The Erlang Web is a framework for applications based on HTTP protocols, relieving the developer from implementing behaviours frequently used in dynamic pages.

Gtk language binding for Erlang with Glade/Gnome support.

An Erlang libary for XML parsing. It supports various modes of operation: as an efficient SAX parser, as a simple DOM-like parser, or as a 'data mapper'. The data mapper transforms the XML document to Erlang records, based on an XML Schema.

Erlang/Scala IDE based on NetBeans. With syntax checking, syntax highlighting, auto-completion, pretty formatter, occurrences mark, brace matching, indentation, code folding, function navigator, go to declaration, project management, shell console.

ErlyMUD is a small MUD server written using the Erlang/OTP libraries. The aim is to have solid support for exploration and roleplaying, within a concurrent, highly fault-tolerant environment.

A semantic memory software tool “reflects” one's “imagination”. In it, arbitrary concepts may be described, stored, arranged, transformed, and shared. One may verbalize thoughts as they arise in the mind to externalize and digitize “mental obj
