Frequently Asked Questions
? Is Atheos hard to install?
Atheos can be installed via Docker (the simplest method) or manual setup on a server with PHP 7.4+ and MySQL/MariaDB. Docker images simplify deployment for users familiar with containerization, while manual setup requires uploading files to a web server and configuring a database—basic server administration skills are helpful here.
? Is it a good alternative to GitHub Codespaces?
Atheos is an excellent self-hosted alternative to GitHub Codespaces for users prioritizing data control and zero costs. While it lacks advanced cloud features like preconfigured workspaces, it offers core IDE functionality (code editing, Git integration) and is ideal for individual developers or small teams not needing enterprise-level tools.
? Is it completely free?
Yes, Atheos is 100% free and open-source under the MIT License. There are no subscription plans, premium features, or hidden fees—all functionality is available to self-host and use without cost.
