Atheos
A self-hosted browser IDE is provided by Atheos, an updated version of Codiad.

About Atheos
Atheos is a self-hosted, browser-based IDE described as an updated and rewritten fork of Codiad. It is intended to run on a web server with a small footprint and minimal requirements.
It can be installed by placing the files in a web-accessible folder or by using a Docker image, and it includes built-in Git integration, a user permission system, and a plugin and module structure. Updates require manual copying of files by an administrator, and it is primarily developed on a Debian LAMP server, so other stacks may encounter installation issues.
