WeblateOrg/weblate
Web based localization tool with tight version control integration.
Weblate is a web-based, continuous-localization platform that lives in your VCS workflow — it pulls translation files from a git/hg repo, lets translators work in a web UI, and pushes commits back. It's aimed at open-source maintainers and companies who need ongoing translation management tied to their existing repo rather than a one-off export/import cycle.
Genuinely tight VCS integration — it treats the repo as the source of truth and round-trips changes as commits, not a separate database silo you have to reconcile. Format support is enormous (gettext, JSON, ARB, Fluent, Android XML, RESX, Qt, Java properties, and dozens more), so it fits into whatever stack you already have. It's a mature, actively maintained project (10+ years, contributor changelogs going back to 5.x with monthly point releases) with real security practice behind it — REUSE license compliance, ClusterFuzzLite fuzzing, CII best-practices badge, an actual accessibility issue template and ACCESSIBILITY.md target.
The README tells you almost nothing — no quickstart, no screenshot, no feature list, just badges and a link out to docs.weblate.org, so you can't evaluate fit without leaving GitHub. Self-hosting is not lightweight: it's a full Django app, and the docs tree alone has separate install guides per OS (Debian, macOS, RedHat, SUSE) plus system-dependency and uv-specific steps, which signals real operational weight (Postgres, likely Celery/Redis) versus a single binary you drop somewhere. GPL-3.0 licensing is a real consideration if you're embedding or reselling rather than just self-hosting. The frontend is a fairly dated stack (webpack, yarn, Bootstrap 5) rather than anything modern, which shows in maintenance burden more than in the product itself.
