What Is LibreTranslate?
LibreTranslate is an open-source machine translation API powered by the Argos Translate library. LibreTranslate's portal, read directly, sells hosted API keys in dollars per month: Pro at $29 with bursts of up to 80 translations a minute and sustained use nearer 20, and Business at $58 with bursts of 200 a minute and sustained use nearer 50. Both include unlimited translations, a 2,000-character limit per call and a 7-day money-back guarantee. There are no free API keys, and the FAQ says low-volume free keys are not sustainable, with higher limits by quote. You can always host your own server, which is the main appeal, and the software is licensed under the AGPLv3, so modified network deployments must share their source.
The homepage advertises text and file translation and shows version 1.9.6, released on May 26, 2026 per GitHub. The most recent commit I saw was October 23, 2026, with frequent translation commits, and the repository shows about 17,200 stars, 1,800 forks and 130 open issues, so it is clearly active. No AI features beyond the underlying neural translation engine are described. Quality follows the Argos models and trails commercial engines on difficult pairs, so test your languages before relying on it.
LibreTranslate suits developers wanting a self-hostable translation API and teams that need data to stay in-house. Compare Argos Translate, Google Cloud Translation and DeepL Translator. Browse the Translation & Language tools directory for more.
