Argos Translate is the engine under LibreTranslate, and you can also use it directly as a Python library, from the command line or in a small desktop app. It runs offline once the language packages are installed, it can pivot through an intermediate language so Spanish to French works through English, and it is dual licensed under MIT or CC0, so you can take your pick.

Argos Translate scores a 5 on lock-in, a 4 on footprint and power and a 3 on self-direction, longevity and delivery.

The money side is on the project page: GitHub Sponsors, PayPal, Venmo and Bitcoin donations, one corporate sponsor, affiliate links to hosting providers, and custom models trained on your data at $1000 a language, negotiable. The maintainer is available for hire. That is a lot of small streams for what looks like a one-maintainer project, and it is a plain description of how the work gets paid for. The first download of each language package needs a connection.

What stands out

• An offline translation library with a command line and a desktop app
• MIT or CC0, with an openly described mix of donations and paid work
• Language packages download first, then work offline

For comparison, we also reviewed Google Translate (17/30) as a benchmark.
