The short version

  • Each has a real cost: Localazy the price ladder is stepped rather than continuous, so a project that grows from 2,500 to 2,600 source keys jumps a whole bracket rather than paying slightly more.; OmegaT there is no commercial support contract available, so a business relying on it for critical work has only community forums to fall back on when something breaks.
  • They diverge on capability: Localazy covers Per source key pricing, OmegaT covers Translation memory.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Localazy

  • A mobile or web application that ships in twenty or more locales, where per-word pricing would multiply the bill by every added marketnot OmegaT
  • An indie developer or small studio that needs a genuinely free tier rather than a fourteen day trialnot OmegaT
  • Teams that want strings pulled from Figma so copy is localised before the interface is built rather than afternot OmegaT
  • Continuous localisation in a build pipeline through the CLI and GitHub Actions, with runtime delivery through the CDNnot OmegaT

OmegaT

  • A freelance translator who wants translation memory and fuzzy matching without paying for a Trados or memoQ licencenot Localazy
  • A small language service provider standardising on a free tool for individual translators before investing in a shared TMSnot Localazy
  • A translator working with files from clients using commercial CAT tools, leveraging Okapi’s format support for compatibilitynot Localazy
  • A developer or power user who wants to inspect, modify or extend the tool since it is open source under the GPLv3not Localazy

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Localazy

  • The price ladder is stepped rather than continuous, so a project that grows from 2,500 to 2,600 source keys jumps a whole bracket rather than paying slightly more.
  • Single sign-on, audit logs, an SLA, priority support and audit trails are all Enterprise-only, and Enterprise is the one tier with no published price, so the moment a security review lands you leave the transparent pricing behind.
  • Counting by source key penalises content models where every paragraph is a separate key, so a documentation site or a marketing site can consume brackets far faster than an application with the same amount of text.
  • Human translation is sold in the platform but its rates only become visible after you have signed up, and whether Localazy takes a margin on that work is not disclosed anywhere public.
  • It is a company of roughly twenty people with no disclosed investors and no published legal entity details, which is a real continuity question for anyone putting a multi-year product localisation pipeline through it.

OmegaT

  • There is no commercial support contract available, so a business relying on it for critical work has only community forums to fall back on when something breaks.
  • It lacks the cloud-hosted, real-time collaborative project management features of commercial TMS platforms like memoQ or Smartling.
  • The interface is a Java desktop application with a dated look and feel compared with modern web-based CAT tools, which affects onboarding speed for new users.
  • Release cadence and feature development depend on volunteer contributor availability rather than a company roadmap, so some requested features take a long time to arrive, if ever.
  • Machine translation integration requires configuring third-party API keys (Google, DeepL) separately, adding setup steps a commercial all-in-one tool would handle natively.

Answered from the vendors’ own pages

Localazy: What exactly is a source key?

One segment of text in your source language, such as a button label or a short paragraph. The same key translated into ten languages still counts as one key, and languages are unlimited on every plan.

OmegaT: Is OmegaT really free, with no paid version?

Yes, it is fully free and open source under the GPLv3, with no commercial edition or vendor support contract sold alongside it.

Localazy: Is the free plan a trial?

No, the 200 key free plan is permanent and includes unlimited seats and languages. Separately, new signups get a fourteen day trial of the Business plan.

OmegaT: Who maintains OmegaT?

A volunteer open source community, not a company; this differs from MateCat, which is developed and hosted by the company Translated.

Localazy: How does it compare with per-word pricing?

It stops scaling with locale count. If you ship in three languages the difference is small; if you ship in thirty, per-key pricing is structurally cheaper rather than marginally so.

OmegaT: Can it open files from Trados or Wordfast?

Yes, via the bundled Okapi Filters plugin, which supports SDLXLIFF, TTX, TXML and many other commercial CAT tool formats.

Localazy: Can I get single sign-on?

Only on Enterprise, which is quoted rather than published. There is no mid-tier SSO option.
