About Ossium
Ossium collects resources for people who want to contribute to open-source software. Its discovery tools include a curated project catalog, trending GitHub repositories, good first issues, Web3 open-source projects, a list of FOSS alternatives to SaaS products and a list of projects that can be self-hosted.
It also lists programs such as Google Summer of Code organizations, fellowships, Y Combinator open-source companies, eligibility requirements and open-source perks like free tools and credits. Product tools include Ossistant, an AI helper for open source, a GitHub selfbot for automating repositories, a repo analyzer and alert rules for issue notifications.
The community section covers a contributors leaderboard, a forum, a bounties board of paid open issues, a learning resource hub and a blog, and maintainers can claim a project by verifying ownership. A jobs marketplace and bookmarks for saved repositories are included. Exploring is free with no login, and a Premium and sponsorship page supports the site.
