Atheos

Atheos is a self-hosted, browser-based cloud IDE and code editor originally built as a maintained fork and major rewrite of the Codiad IDE. It focuses on a small server footprint while providing a modern in-browser development experience for teams or individuals.

Key Features

• Web-based editor with file/project management and split editor views
• Multi-user support with a more complete permission system
• Built-in Git integration
• Plugin system with a library/marketplace for extending functionality
• Editor productivity features such as advanced search tools, autocomplete, and syntax themes
• Error checking, notifications, and client-side resilience features (for example LocalStorage redundancy)

Use Cases

• Lightweight, self-hosted development environment for small teams and homelabs
• Remote editing and quick project changes on servers without installing a desktop IDE
• Extensible web IDE platform for building custom plugins and workflows

Limitations and Considerations

• No built-in automatic updater; upgrades typically require manually copying files while preserving config/data/workspaces
• Designed for a classic PHP web stack and expects certain directories to be writable by the web server

Atheos is a practical option when you want an in-browser IDE that is easy to deploy, does not require a database, and can be customized through plugins. It aims to keep the simplicity of Codiad while modernizing the codebase and adding features for day-to-day development.
