  • Each has a real cost: MateCat the hosted version most users rely on depends on Translated srl’s continued operation and infrastructure decisions, unlike a self-run desktop tool.; SDL Trados Studio it runs on Windows only, so macOS translators pay for a virtual machine or a second computer before they can accept work.
  • They diverge on capability: MateCat covers Browser-based CAT interface, SDL Trados Studio covers Term base integration.

Where each one falls short

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

MateCat

  • The hosted version most users rely on depends on Translated srl’s continued operation and infrastructure decisions, unlike a self-run desktop tool.
  • It is developed by a commercial translation company whose own paid services sit alongside the free tool, which is worth being aware of when evaluating vendor neutrality.
  • Being browser-based, it requires a stable internet connection, unlike OmegaT’s fully offline desktop application.
  • Advanced terminology management and enterprise-scale project features are more limited than a paid commercial TMS such as memoQ or Smartling.
  • Self-hosting the open source LGPL code independently of Translated’s hosted service requires technical setup effort that most individual translators are unlikely to undertake.

SDL Trados Studio

  • It runs on Windows only, so macOS translators pay for a virtual machine or a second computer before they can accept work.
  • A perpetual licence covers the version you bought, and each major release is a further purchase, so the total cost over five years resembles a subscription without being described as one.
  • The learning curve is long: project settings, filters and memory configuration have to be understood before quality output is possible, which makes casual use impractical.
  • Memories and projects are local by default, and real collaboration needs GroupShare or the cloud tiers at extra cost, so two translators sharing one memory is a paid upgrade.
  • Third party plugins from the app store are maintained by their authors and frequently stop working after a major Studio release, which strands workflows that depend on them.

Answered from the vendors’ own pages

MateCat: Is MateCat really free?

Yes, it is free to use as a hosted browser-based tool and released as open source under the LGPL.

SDL Trados Studio: Is it still called SDL Trados?

The product is now sold as Trados Studio by RWS, which acquired SDL in 2020. Older documentation and job adverts still say SDL Trados.

MateCat: Who maintains MateCat?

Translated srl, an Italian translation company, develops and hosts it; this differs from OmegaT, which is maintained by a volunteer open source community.

SDL Trados Studio: Do I need it if my clients use a cloud TMS?

Often yes. Agencies still send Studio packages, and accepting them without the tool means manual conversion and lost memory matches.

MateCat: Can I self-host MateCat instead of using Translated’s hosted version?

The code is open source under the LGPL and technically self-hostable, but doing so requires meaningful technical setup most individual users skip in favour of the hosted service.

SDL Trados Studio: Can I run it on a Mac?

Not natively. Translators use Parallels, Boot Camp on older hardware, or a Windows virtual desktop.
