How it got here

What the classifier decided, and when.

Classified as an open-source startup by Jev, TypeSafe’s classifier, on 22 Sep 2026 — os_startup 41%, self-hostable 69%, hosted offering 21%. The classifier reads only the repository’s name, description and homepage; it can be wrong, and a probability under 0.5 puts a listing in the review queue rather than out of the directory.

Listed since the Sep 2025 crawl. Answered by jev-1.13.0. How the classification works →

Updates daily, from the last push GitHub saw.

Honest caveat: GitHub proxies README images through Camo and rewrites the anchor with rel=“nofollow”, so a README embed sends you referral traffic and brand, not link equity. The link is dofollow wherever you control the markup — your docs, your landing page, your blog. The snippet uses your frozen OSSEAN slug, so it survives a repo rename.
