Sometime in 2024 Forgejo became hard fork no longer merging Gitea code so both projects slowly diverge. But i think momentum is on Forgejo side. Codeberg is popular and development seems to be stable and solid.
I'm on the Gitea TOC. The fork does still merge from upstream. The Gitea project has 4x'd the number of monthly PRs we handle (~400) and have increased the maintainers teams, and the number of contributors. I'd say we have a lot of momentum.
