A tiny mouse, a hacker.
Forgejo has no official Windows builds, and since it is not tested on windows at all, it’s not guaranteed to work.
Fair bias notice: I am a Forgejo contributor.
I switched from Gitea to Forgejo when Forgejo was announced, and it was as simple as changing the binary/docker image. It remains that simple today, and will remain that simple for the foreseeable future, because Forgejo cherry picks most of the changes in Gitea on a weekly basis. Until the codebases diverge, that will remain the case, and Forgejo will remain a drop-in replacement until such time comes that we decide not to pick a feature or change. If you’re not reliant on said feature, it’s still a drop-in replacement. (So far, we have a few things that are implemented differently in Forgejo, but still in a compatible way).
Let me offer a few reasons to switch:
It’s about 5 times longer than previous releases were maintained for, and is an experiment. If there’s a need for a longer term support branch, there will be one. It’s pointless to start maintaining an 5+ year branch with 0 users and a handful of volunteers, none of whom are paid for doing the maintenance.
So yes, in that context, 15 months is long.
