POEditor
A competent engineer can build a useful self-hosted TMS that covers POEditor's core workflows in a few months; POEditor’s durable advantages are compliance, EU-hosting, and polished enterprise features which are expensive to replicate but don't prevent a small replacement for typical teams.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All POEditor alternatives, with the arithmetic →
What a replacement has to do
- A minimal self-hosted replacement must ingest localization files, store and version strings, provide an online editor for translators with real-time edits and comments, export/import via API and repo integration, and apply basic translation memory / QA checks.
What it still won’t have
- ISO 27001 certification and associated compliance assurances
- EU-hosted physical infrastructure guarantee and related DPA specifics
- Official MCP server for tightly integrated AI tooling
- Enterprise-grade polished UI, SLAs (99.9% uptime claim), and vendor support
- Built-in marketplace of language service providers and ordering flow
What remains hard
- Compliance and regulation
ISO 27001 certified

Runnable build prompt
Build a self-hosted minimal translation management system using Next.js (React) frontend, Postgres database, Node.js (Express/Fastify) backend, Redis for realtime presence, and Docker for deployment. In scope: import/export of JSON, XLIFF, PO; project and contributor models; online editor with realtime presence, inline comments, and basic locking; REST API for push/pull; GitHub webhook to import base files; translation memory (exact-match reuse) and a simple QA checker for placeholders/punctuation; authentication (email/password + optional OAuth). Out of scope: enterprise SSO integrations, ISO27001 certification, hosted EU physical infra guarantees, MCP server, and LSP ordering marketplace. Deliverables must include database schema, OpenAPI spec, Docker compose and production deployment docs, unit and integration tests covering parsing, API endpoints, and editor actions, and error handling/logging for imports, exports, and background jobs.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
