Polylens vs Crowdin

Crowdin coordinates translation work. Polylens tells you whether what shipped is broken.

Crowdin is a popular TMS with hundreds of integrations, community translation features, and per-seat plans. Like every TMS, its center of gravity is the translation workflow: getting strings translated by people.

Polylens sits after all of that, where the files actually ship. It scans what is in your repo, scores every language, and gates CI so a missing key or a dropped {{placeholder}} never reaches a customer.

Crowdin gets strings translated. Polylens proves the shipped files are healthy. If you only need the proof, you do not need the platform.
