Frequently asked questions
How many open source antigravity projects are there?
This registry tracks 14 projects tagged antigravity, with 182,260 GitHub stars between them. The most-adopted is graphify at 141,064 stars.
Are these antigravity projects free to use?
Yes — 14 of the 14 carry an explicit open-source licence across 2 distinct licences, so there is no licence fee. Where a project also sells a hosted or enterprise version, the self-hosted path remains free.
Which antigravity project should I choose?
The list above is ranked by GitHub stars, but stars measure attention rather than fit. Check three things on each card: the licence (permissive versus copyleft), the language it is written in, and the last-push date — a high-star project that has not been pushed in a year is a liability.
Are these antigravity projects still maintained?
13 of the 14 were pushed in the last 90 days, and every card shows its exact last-push date so you can see the rest. Sort your shortlist by that date before committing to a migration.
