Co-op Translator across Microsoft open source
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.
GitHub-native workflow
From source changes to reviewable pull requests.
Localizeflow detects repository structure, runs translation workloads outside CI, and returns the result through GitHub.
Translate outside CI, then return synchronized updates as GitHub pull requests maintainers can review and merge.
