Where each one falls short

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

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.

Unbabel

  • The attractive low per-word rate requires a minimum annual commitment reported around $120,000, which prices out most small and mid-sized businesses.
  • It should not be compared directly to per-character machine translation APIs, since the pricing unit, inclusion of human review and use case are all different, and doing so understates the real cost.
  • Turnaround time is inherently slower than pure machine translation, since human post-editors are part of the pipeline, which matters for real-time chat use cases.
  • Public pricing detail is limited outside the enterprise tier, so smaller buyers get little transparency into what they would actually pay before a sales conversation.
  • Quality and turnaround depend partly on the availability of the human post-editor network for a given language pair, which can vary for less common languages.

Answered from the vendors’ own pages

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.

Unbabel: Is Unbabel comparable to Google Translate’s API on price?

No, they are different products: Unbabel is a managed service billed per word with human post-editing included, while Google’s API is raw machine translation billed per character.

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.

Unbabel: What is the minimum commitment?

Enterprise pricing has been reported as requiring a minimum annual commitment around $120,000, which is a meaningful barrier for smaller buyers.

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.

Unbabel: Does Unbabel offer fully human translation?

Yes, alongside raw machine translation and MT-plus-post-edit tiers, priced differently by the level of human involvement.
