Open-source startup atlas
OSSEAN
Curated, then kept alive
The directory for open-source startups that still ship.
OSSEAN now combines a fast checked-in startup snapshot with cached live GitHub repo data on featured cards and detail pages. Browse quickly, then drop into the pulse of the repos that matter.
Stay Close
Get new companies and sync notes without the noise.
I'll only use this for meaningful directory updates, launches, and notable additions to the open-source startup landscape.
Email capture works when the Redis-backed KV env vars are configured.
Live Pulse
A few projects, updated beyond the snapshot.

Featured cards fetch fresh GitHub repo data through a cached API layer. Full directory cards stay fast by using the checked-in snapshot.
Search fast
Directory cards stay snappy.
The explorer hydrates from the local snapshot, so search and filtering stay instant instead of waiting on hundreds of live API requests.
Check live state
Featured repos and detail pages sync with GitHub.
High-value surfaces fetch cached live stats so you can tell what moved since the last saved data refresh.
Sync lightly
Full re-ingestion stays optional.
You can still refresh the whole directory with the existing sync script, but the site no longer feels frozen if that job runs less often.

Common topics
Current state
The app is no longer just a static hero plus list. It now has a normalized data layer, live GitHub sync endpoints, a searchable explorer, and richer detail pages.
The snapshot is still the backbone, which keeps browsing reliable on Vercel and Cloudflare. Live fetches are targeted instead of all-or-nothing.
Directory Explorer
Search the ocean, then narrow it fast.
Find projects by name, org, language, or topic. Cards use the checked-in directory snapshot, while repo pages layer on live GitHub data.
