 - Configuration is stored in a simple config file, avoiding the need for a backend/database while making it possible to use versioning or [config template](https://docs.ansible.com/ansible/latest/user_guide/playbooks_templating.html).
 - Only modern browsers are supported, feel free to use any JS features without any polyfill as soon as the latest version of the major browsers supports them.

However, for specific agent like Claude Code or Gemini, you will have to specifically ask it to read the file or create symlink:
