A community-driven list of open source alternatives to proprietary software and applications, helping users discover and choose OSS replacements.
OpenAlternative is a community-driven directory that lists open source alternatives to proprietary software. The site curates projects, highlights active development, and uses a health score algorithm (based on GitHub metrics, recent activity and contributors) to rank projects so users can find well-maintained options quickly.
The directory covers a wide range of categories including developer tools, productivity & note-taking, analytics, AI & ML platforms, self-hosted apps, devops & deployment, and many more featured categories listed on the site.
Submitting a project is free — the site provides a submission form and links such as "Add a Free Listing" indicate free listing options for open source projects.
