## Notes

- Licenses and star counts are refreshed from the GitHub API and can change. Check each project before you adopt it.
- "Open source" here means source is publicly available. Some entries use fair-code or source-available licenses and are marked as such.

## Data sources

- **Curated entries:** the original tool-to-alternative pairs are maintained by hand in [`data.json`](data.json).
- **Discovered entries:** more pairs were found with the [GitHub Search API](https://docs.github.com/en/rest/search/search#search-repositories) by looking for public repositories whose description says "alternative to X". Those entries reuse the repository's own GitHub description, and a human decided which targets are paid SaaS products.
- **Ordering:** a hand-picked set of household-name apps (see [`featured.json`](featured.json)) comes first, then the rest by the [Tranco](https://tranco-list.eu) ranking of each product's website. Products that share a giant parent site (Google, Microsoft, Adobe, Amazon) aren't ranked by that site's traffic. Categories are ordered by their most popular app. Alternatives within an app are listed as submitted.
- **Stars, licenses and last-push dates:** pulled from the [GitHub REST API](https://docs.github.com/en/rest/repos/repos#get-a-repository) and refreshed weekly. Where GitHub can't detect a license, the entry says "See repo".
- **Community submissions:** added through the [issue form](../../issues/new?template=add-alternative.yml) and pull requests.
- **Verification:** the original curated pairs were cross-checked against independent sources (comparison articles and directories). Where a project replaces only part of a product, its description says so.
- **Disclosure:** some listed projects are maintained by the author of this list ([Anil-matcha](https://github.com/Anil-matcha) and [SamurAIGPT](https://github.com/SamurAIGPT)). Each one's own repository description claims it as an alternative to the listed app.
- This list does not copy data from AlternativeTo, OpenAlternative or other directories.
