Weblate is the open-source translation platform behind a large share of free-software localisation: it watches your Git repository, exposes strings to translators in a web UI, and commits translations straight back with attribution. Hosted plans are tiered by number of strings; libre public projects get the 160k tier free, and self-hosting costs nothing but the server.
