Open Source Erlang Internet Software

Cowboy is a small, fast, modern HTTP server for Erlang and OTP applications. It provides a complete HTTP stack while keeping the codebase compact and optimized for low latency and low memory usage. Cowboy supports routing, request dispatching, HTTP handlers, REST handlers, WebSocket connections, and long-lived streaming-style interactions. Because it uses Ranch for connection management, it can be embedded directly inside larger Erlang systems rather than deployed only as a separate web server. The project is well suited for real-time systems, APIs, messaging infrastructure, telecom-style applications, and fault-tolerant services that benefit from the Erlang runtime. Cowboy is a strong choice when developers need an efficient HTTP layer that fits naturally into actor-based, concurrent Erlang architectures.

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

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.

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

mod_xsl - an XSL transformation module for the Inets erlang webserver

N2O is an embeddable message protocol loop library for WebSocket, HTTP, MQTT and TCP servers. It provides basic features, such as process management, virtual nodes ring for request processing, sessions, frame encoding, and unified API for external mq and caching services.

Implementation of the various WAP standards in Erlang. Includes a WAP Gateway, a simple WAP Client (no rendering) and related tools.

"Virtual Infrastructure for Applications and Services Over IP" ViaSIP_NG using latest OpenCloudComputing recommendations to develop Scalable Private-Public cloud platforms. ViaSIP is leveraging ODS - LinkedData, CouchDB, Eucalypus, DatR.ws & Web2Py.

Vundle.vim is one of the original plugin managers for Vim, designed to make discovering, installing, and updating plugins as simple as editing your vimrc. It uses a declarative, Git-backed approach where each plugin is listed as a line, and Vundle takes care of cloning and wiring it in. The interactive interface supports searching for plugins from inside Vim, which lowers the barrier to exploring the ecosystem. Its core model emphasizes repeatability: your vimrc is the source of truth, making your setup easy to share across machines or teams. Vundle also provides commands to clean out unused plugins and to update all dependencies with a single keystroke. While newer managers exist, Vundle remains a straightforward, battle-tested choice that many guides and dotfiles still rely on.

A high-level framework for web-based community development of web applications. The code is released under the Erlang Public License - the same license which is used for Erlang/OTP.

hackney is an HTTP client library for Erlang. No message passing (except for asynchronous responses): response is directly streamed to the current process and state is kept in a #client{} record. Binary streams, SSL support, keepalive handling, basic authentication. Stream the response and the requests, fetch a response asynchronously, multipart support (streamed or not), and chunked encoding support. It can send files using the sendfile API. Optional socket pool, REST syntax, hackney, Method(URL) (where a method can get, post, put, delete, ...)

This is a wiki server enabling the public to edit not just the text pages, but the programming behind them. The prototype is written in Erlang with a built-in Scheme interpreter to run user's code.

Yaws is a small fast and beautiful HTTP 1.1 webserver with excellent support for generating dynamic content. Yaws has been moved to github. http://github.com/klacke/yaws/

PHP 5.x module providing interface to Erlang/OPT application nodes trough Erl_Interface C library, mainly intended for use in server enviroments to interconnect Web scripts with Erlang/OTP server software.
