Rankings and alternatives

Self-hosted machine translation scores

Evaluated Nov 8, 2026 Evidence ↓
  • Time to first translation 5

    5/5 means: A downloadable build for Windows, Linux, and Mac

    The README says you can download a build for Windows, Linux, and Mac, including compatibility builds for old hardware and M1.

  • Stays on your machine 5

    5/5 means: A desktop or library the project describes as translating on your own machine

    The README describes translation on your local machine, and the command help text says translations are performed locally. translatelocally.com redirects to private.mt, which calls it a desktop app.

  • Languages 3

    3/5 means: A stated list of stable pairs, or downloadable models with no published total

    Bergamot is the default model repository and OpusMT can be added. The README and the company page do not publish a count of languages. Extra language support is "contact us", with no list.

    Rests partly on what the sources don't mention, which is a weaker signal than what they say.

  • Calling it from software 3

    3/5 means: Native messaging, or a toolchain another program can call

    Other applications and browser extensions can use native messaging. Translator settings can only be changed in the GUI, and the pages checked do not document an HTTP API.

  • What keeps running 5

    5/5 means: Prebuilt binaries and model files, and no database

    The documented way to run it is a downloaded build. Qt, libarchive, and Intel MKL are requirements for compiling, and the README discourages OpenBLAS because it is slower than MKL.

Pricing

  • Desktop app Free The company page says the desktop app is free. Extra languages are by contact, with no price printed.

From the vendor’s pricing page, checked Nov 8, 2026. That page is authoritative.
