How it got here

What the classifier decided, and when.

Read by Jev, TypeSafe’s classifier, on 22 Sep 2026, which did not call this an open-source startup — it chose a package or library instead, and put os_startup at 5% (self-hostable 86%, hosted offering 11%). 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. This one is in that queue, waiting for a person — removing a listing is a pull request a human opens.

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.
