Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
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.
Weglot
- Free plan is capped at 2,000 words and a single language
- Starter plan at $17 per month is limited to 1 language; reaching 3 languages requires the $32 per month Business plan
