Catalog of open source apps and tools.
A curated, editorial catalog of mainstream, trustworthy Free and Open Source Software (FOSS). The goal is quality and practical adoption—not exhaustive listings.
- FOSS-CATALOG.md — Full catalog by category (primary reference).
- LICENSE-NOTES.md — How OSI-approved and recognized licenses are treated in this project.
Entries must be genuinely open source (see license notes), actively maintained, well documented where it matters, and credible for real-world use. Source-available or non-OSI licenses that fail the project’s “genuinely open source” bar are excluded.
This catalog is a living document. Verify licenses, release cadence, and project status before major adoption decisions.
A production-oriented Next.js site lives in site/: browse, filters, tool pages, comparison, SEO, and accessibility. From the site folder run npm install and npm run dev.
