osmods, the mod layer for open source

Why it surfaced

The homepage turns customization into a visible sequence: choose an app such as PostHog, agree on a plan, compare the original and modified instances, then keep the change only after it works on real data. Its public catalog and session stories give the idea an unusually concrete community thesis: useful mods become shared, verified answers rather than private forks.

osmods lets people describe changes to open-source apps in plain language, test them on a live instance, and keep a working version without maintaining a fork.
