## The panel's verdict

Transifex is a translation platform the bench scores highest on integrations and formats — top marks of 8 from three of six judges — for a documented REST API with an OpenAPI specification, Python and JavaScript SDKs, a CLI for Jenkins and Travis, Git sync across GitHub, GitLab, Bitbucket and Azure Repos, over-the-air SDKs and 46+ file formats. Machine translation and workflow follow at 7-8: eight named engines assignable per language pair, real-time quality scoring that routes weak output to review, an always-included review step and checks configurable with regular expressions. Confidentiality and portability sit at 5-6, held back by no public statement on whether customer texts are used to train models. Sovereignty scores 4: the terms name Transifex Opco LLC of Covina, California under Delaware law, the security page puts hosting on AWS in Ireland, and the privacy policy says information may be viewed and hosted anywhere in the world. The bench genuinely splits — three judges scored 0 across all seven criteria, pairing the same tooling with unanswered questions on provider locations, retention and unpriced plan gates.

**Speaks for it:**
- Integrations and formats scored the top mark of 8 from three of six judges: a REST API with a downloadable OpenAPI specification, Python and JavaScript SDKs, a CLI for Jenkins and Travis, Git sync across GitHub, GitLab, Bitbucket and Azure Repos, over-the-air SDKs, and 46+ file formats.
- Eight named machine translation engines can be assigned per language pair with organization defaults and per-project overrides, and the Translation Quality Index routes weak output to reviewers in real time.
- A review step is always included in the workflow with optional proofreading per project, quality checks configurable with your own regular expressions, and a glossary checked automatically during translation.
- Translation memory exports as TMX with language selection (exports up to 500MB, imports up to 200MB) and the terms grant customers full ownership of their words including the translated content.
- Seats never affect the price, hosted words are included at no charge, and human review never counts toward usage.

**Held against it:**
- The terms name Transifex Opco LLC of Covina, California under Delaware law while the security page puts hosting on AWS in Ireland, and the privacy policy says information may be viewed and hosted anywhere in the world.
- We found no public statement on whether customer texts are used to train models, no zero-retention terms with the named AI providers, and no scope published for the claimed SOC 2 Type II certification.
- Content is retained while the account is active plus thirty days after termination as a courtesy, backed-up versions might exist after deletion, and files shared with other users are not deleted.
- The published 85-90% machine translation accuracy figure comes without its method, and the terms state the AI quality score is a courtesy with no guarantee of accuracy.
- No price figure appears on the captured pages, and the captured pages give different pictures of plan structure — the pricing page says there are no tiers while help pages place automatic machine translation on Growth and style guides and single sign-on on Enterprise Plus.

**Best for:**
- You ship localization through CI/CD and app releases, where the CLI, two-way Git sync and over-the-air SDKs for iOS, Android and web earned the bench's top integration scores.
- You want to run different machine translation engines per language pair with quality-scored routing to review — eight named engines, organization defaults and per-project overrides scored 7-8.
- You need your translation assets to stay portable — translation memory exports as TMX with language selection up to 500MB, glossaries import and export, and the terms grant you full ownership of your words.

**Avoid if:**
- You need an EU contracting party or a documented EU processing chain — the terms put you under Delaware law with Transifex Opco LLC of Covina, California, while the privacy policy says information may be viewed and hosted anywhere in the world.
- Your retention policy requires deletion on exit — content is kept while the account is active plus thirty days after termination as a courtesy, backed-up versions might exist after deletion, and files shared with other users are not deleted.
- Your procurement cannot accept strict contract terms — the terms set a 60-day non-renewal notice, non-refundable payments, renewal fees that may rise to list price, and a one-year limit to bring claims under Delaware arbitration.

## Scores by judge and criterion

Scores out of 5, each judge scoring independently against the published rubric (v1). "n/r" = not rated: the vendor publishes no price, or the judge found no public information on that criterion.

### The judges

- **The Localization Manager** (v1.0): Runs localization for a Hamburg software company whose product, help centre and marketing site ship in fourteen languages, with two agencies and a pool of freelancers. Every release brings a few thousand new strings and a deadline. Wants one translation memory and termbase across all content, machine translation that respects the glossary, review steps per language, QA checks that stop a broken placeholder before it ships, and cost and progress per vendor in one view.
- **The App Developer** (v1.0): Lead developer of a web app and two mobile apps at a Vienna start-up, with strings in JSON, xcstrings and Android XML. Has hand-merged translation files once and will not do it again. Wants a CLI and a GitHub sync that opens pull requests, over-the-air updates so a typo fix does not need an app store release, an API that does everything the interface does, and ideally an open-source edition they could run themselves if the vendor changes course.
- **The In-House Document Translator** (v1.0): Works in the legal and export team of a machine builder in Baden-Württemberg with customers in France, Italy, Poland and China. Translates contracts, operating manuals and supplier correspondence every day, with no translation management system and no wish for one. Needs translations that read like the company wrote them, the company's terms kept through a glossary, Word and PDF files back with their layout intact, and a written promise that a draft contract is not kept or used to train anything.
- **The Data Protection Officer** (v1.0): Data protection officer of a health insurer whose staff translate letters to members, HR documents and internal guidelines. Found a free translator in the proxy logs and had to explain to the board what had been pasted into it. Reads the terms before the feature page: how long texts are kept, whether they train a model, which engines and LLM providers a platform passes them to, who the subprocessors are and where, and whether the contract names a European entity.
- **The E-Commerce Marketer** (v1.0): Runs marketing for a Shopify shop selling cycling apparel from Munich, live in German and English and due in French, Italian, Dutch and Spanish before the spring season. Has no developer and no translator on staff. Wants product pages, checkout and emails translated in days, a way to fix a bad product name by hand, multilingual SEO that search engines index, and a monthly price that does not double when the catalogue grows.
- **The Skeptic** (v1.0): Has seen "human quality" on an engine nobody has evaluated in public, "we never store your data" next to a TMS that forwards every segment to three LLM providers, and a translation memory built over six years that could only leave as a spreadsheet. Reads that a product is "enterprise-grade secure" and asks how long the text is kept, which models it reaches, and whether the memory and termbase export as TMX and TBX — and what leaving would cost.
