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.
Discovered entries: more pairs were found with the GitHub Search API 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) comes first, then the rest by the Tranco 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 and refreshed weekly. Where GitHub can't detect a license, the entry says "See repo".
Community submissions: added through the issue form 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 and 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.

Contributing

Add or edit entries in data.json, then run:

GITHUB_TOKEN=... node scripts/refresh-stats.mjs
node scripts/build-readme.mjs

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.
Discovered entries: more pairs were found with the GitHub Search API 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) comes first, then the rest by the Tranco 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 and refreshed weekly. Where GitHub can't detect a license, the entry says "See repo".
Community submissions: added through the issue form 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 and 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.

Contributing

Add or edit entries in data.json, then run:

GITHUB_TOKEN=... node scripts/refresh-stats.mjs
node scripts/build-readme.mjs
