Localizeflow is the production layer on top of Co-op Translator
Built to run multilingual documentation at scale.
Originally developed for Microsoft open-source ecosystems.
Powering multilingual docs for open-source on GitHub
Built on Co-op Translator
The open-source engine used across 16 Microsoft OSS repositories and 50+ languages.
Co-op Translator made multilingual documentation possible.
But as documentation grew across repositories and languages in Microsoft open-source projects, GitHub Actions workflows started to break down.
Where CI starts to break
- Jobs became too large and slow
- CI time limits caused failures
- Large translation workloads were hard to manage
- Recovery and retries were unreliable
Localizeflow was built to solve these problems.
It moves translation workflows beyond CI, splits large jobs into distributed workloads, and ensures reliable PR-based synchronization at scale.
Built for real-world documentation systems.
Production translation workflows for open-source ecosystems, developer platforms, and educational content at global scale.
Coordinate multilingual docs across many repositories, maintainers, and release cadences.
