Open-source startups gaining stars fastest.

History on OSSEAN began on 2026-08-11 and is sampled once a week, so there are 9 columns behind every line here and no sample between them. A project that joined the directory recently shows no delta rather than a guessed one: with a single measurement there is nothing to subtract, and inventing a baseline would make the newest arrivals look like the fastest climbers.
