What Is Argos Translate?
Argos Translate is an open-source offline translation library built on neural machine translation. The project site, read directly, says it is dual licensed under MIT or CC0, GitHub shows an MIT licence, and the engine is built on OpenNMT and CTranslate2 rather than a large language model. It ships as a Python library, a command-line tool and a GUI app, with a live demo at LibreTranslate. There is no API pricing because you run it yourself. The only price on the site is for custom work, stating custom models trained on your own data are available for $1,000 a language, negotiable, and donations are accepted by GitHub Sponsors, PayPal, Venmo and Bitcoin.
The GitHub repository showed a last commit on August 8, 2026, a slow cadence of roughly every few weeks, and about 6,600 stars, 505 forks and 157 open issues. The only listed release was the macOS app 1.4.0, dated 24 August with no year shown, and a library version commit dated October 2025. I saw no sign of abandonment, though the issue backlog is large. Quality is solid for common language pairs but behind cloud engines for rare ones, and models download per language pair. Running offline means no data leaves your machine, which matters for confidential files.
Argos Translate suits developers and privacy-conscious users who need free offline translation. Compare LibreTranslate, DeepL Translator and Google Translate. Browse the Translation & Language tools directory for more.
