Open source software development - localization
Localization is the process of adapting code and software to other languages. 5 self-hosted localization tools are listed here, ordered purely by a repository health score that Repoly recomputes nightly. Weblate leads at 95/100 with 3,791 commits in the last 90 days and 6.1k stars, followed by Tolgee (94) and Traduora (93). 4 of the 5 score 70 or above, 5 publish a Docker image, and the median health is 93. GPL-3.0 is the most common licence, carried by 1 of them. Between them they stand in for Crowdin and Lokalise. The score weighs commits in the last 90 days, release recency, stars, archive status and Docker support; a low number means low measurable activity, not low quality, so a finished, stable tool can legitimately sit lower down.
