Atheos Cloud IDE
Atheos is an open source, web-based, cloud IDE and code editor with minimal footprint and requirements, built on top of Codiad by Fluidbyte
Categories:
Atheos is a lightweight, self-hosted, web-based IDE framework forked from Codiad, designed for developers who need a fast, minimal-resource coding environment in the browser.
🚀 Overview
Atheos is a web-based IDE that runs on your own server with minimal requirements—no database needed, just PHP and a web server. It solves the problem of bloated desktop IDEs or expensive cloud services by providing a simple, performant alternative for interactive development directly in the browser.
It's built for solo developers, hobbyists, indie makers, and small teams looking for self-hosted collaborative coding without heavy overhead.
The project was created to modernize and maintain Codiad, incorporating cleaner code, modern UX, reduced traffic, and new features like built-in Git while keeping the small footprint.
