## The panel's verdict

SimpleLocalize, a translation-management service from Jakub Pomykała Software, a sole proprietorship in Wrocław, Poland, scored strongest on integrations and formats (7 to 9): a native CLI, a GitHub App that opens pull requests, over-the-air SDKs for Android, iOS and macOS, a REST API with an OpenAPI spec and thirty-plus file formats are documented. Weakest is portability and exit (4 to 5): exports run to formats including Excel and JSON, but we found no public information on exporting the translation memory or glossary as TMX or TBX, on a migration path from another tool, or on a self-hosted edition. Sovereignty scores hold at 7 on exclusively AWS EU hosting, encrypted EU backups and a published data processing agreement; the EU-storage promise carves out optional machine translation and AI features. Pricing transparency scores 7 to 8, with all four tiers public from Community at €0 for ever to Business at €99 / month billed yearly. Judges' differences stayed narrow — never more than two points, widest on integrations and formats, where the developer persona scored 9 and the data protection officer 7.

**Speaks for it:**
- A native CLI on Windows, macOS and Linux, a GitHub App that opens pull requests, and over-the-air SDKs for Android, iOS and macOS are all publicly documented
- Auto-translation runs through named engines — DeepL, Google Translate, OpenAI, Anthropic, Gemini, OpenRouter or a custom endpoint — and using your own API key does not consume the plan's character quota
- Customer data is hosted exclusively in AWS EU regions, with daily encrypted backups in geographically redundant EU locations, under a publicly available data processing agreement
- All four tiers and add-ons are public — Community €0 for ever, Developer €12 / month billed yearly, Team €35 / month billed yearly, Business €99 / month billed yearly, plus +500 translation keys €5.00, +250k characters €12.00 and +25 team members €25.00 — with no per-user upcharge
- Translation memory applies 100% matches before any engine is called, and automated QA checks for placeholders, broken HTML, ICU syntax and length can block publishing

**Held against it:**
- We found no public information on exporting the translation memory or glossary as TMX or TBX, on a documented migration path from another tool, or on a self-hosted edition
- We found no public information on the translation-key allowance included in each tier, so an annual cost at volume cannot be computed from the public pages
- We found no public information stating that translated texts are not used to train models, or on zero-retention terms with the AI providers
- The ISO 27001 and SOC 2 certifications cited belong to the data centres and hosting infrastructure, with only SOC 2 readiness claimed for the vendor itself
- We found no public information on documented API rate limits, on ordering human translators or agencies inside the product, or on per-segment quality scoring

**Best for:**
- You ship iOS, Android or web software and want a CI-friendly pipeline that returns pull requests and serves translation fixes over the air without a store release
- You want to choose or swap translation engines as cost and quality change, including running local models so texts stay on your own infrastructure
- You must keep customer data in the EU and show your buyer a publicly available data processing agreement with a named subprocessor list
- You are a solo developer or small team budgeting from public prices, starting at Community €0 for ever or Developer €12 / month billed yearly

**Avoid if:**
- Your compliance policy rules out any optional non-EU processing, since the EU-storage promise carves out optional machine translation and AI features
- You require the vendor's own ISO 27001 or SOC 2 certification in the contract, as the published certificates cover the data centres and hosting infrastructure and the vendor's own claim is SOC 2 readiness
- You must compute your full annual cost before committing, as all plans are subject to a Fair Use Policy and we found no public information on the per-tier translation-key limits
- Your exit plan depends on exporting your translation memory and glossary in open formats such as TMX or TBX — portability and exit scored 4 to 5, the lowest-scoring criterion

## 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.
