The short version

  • Only OmegaT has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Plunet pricing is never published and licensing is per user, so a growing agency faces a recurring negotiation each time it adds project managers.
  • They diverge on capability: OmegaT covers Translation memory, Plunet covers CAT tool connectors.
  • Prices and features above were last checked on 1 September 2026.

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.

Plunet

  • Pricing is never published and licensing is per user, so a growing agency faces a recurring negotiation each time it adds project managers.
  • Configuration to match an agency real workflow is substantial, and firms report months of setup before the system reflects how they actually work.
  • It manages the business layer only; you still need and pay for separate CAT tools, so total software spend is higher than the Plunet quote alone suggests.
  • The interface is dense and built for full-time project managers, which makes it a poor fit for occasional users or very small teams.
  • Reporting and dashboards are functional rather than modern, and firms wanting BI-grade analytics typically export data to a separate tool.
