## How this list was made

- Self-hosted apps: commits in the last 12 months from the GitHub API (development activity, not star growth, which the apps snapshot does not track).
- MCP servers and agent skills: average stars per day since the repository was created (a launch-growth proxy until a week of daily star history exists), at most one entry per repository.
- Archived projects and apps with no commit in the last two years are left out.

## FAQ

### How is trending measured?

For self-hosted apps, by commits in the last 12 months. For MCP servers and agent skills, by average stars per day since the repository was created. GitHub's own trending page uses stars gained over a day, week or month, so the two lists can differ.

### Is PostHog free?

Yes. PostHog is open-source software released under the MIT license, so you can self-host it at no cost. You only pay for the server it runs on, and some projects also offer an optional paid cloud plan.

### How often is this list updated?

The appsgit catalog is refreshed from the GitHub API on a schedule, and this page is rebuilt from each new snapshot.
