Product · Glossa
Localisation that lives in your repo, not in a per-seat SaaS.
Extract every translatable string from your code. Translate the missing ones. Verify the translations are safe. Keep it all in files that merge without conflicts.

What you get
What Glossa does.
Every framework
React, Vue, Svelte, Solid, iOS Swift, Android XML, Flutter, Python, Go, Ruby, PHP, and resource formats like JSON, YAML, PO, Fluent and XLIFF.
A safety gate
Translations that drop a variable, break a markup tag or smuggle in HTML or scripts are rejected before they reach production.
Merge without conflicts
The lockfile merges in any order, so two people translating different features do not collide.
Typed messages, no runtime
Generate TypeScript or Rust accessors with compile-time checks, and edit copy in context with a local visual editor.
How it works
Three steps.
- 1
Extract
Lift strings from every supported source into one intermediate form.
- 2
Translate
Fill missing keys with your provider, reusing prior translations.
- 3
Verify
Run the integrity gate and a CI check on coverage.
Limits up front.
Know the limits
- Glossa is built to replace tools like Lingo.dev, Inlang, Tolgee and Crowdin. Speed and memory figures are the project's own measurements against real tool runs, not independent results.
- Translation quality depends on the provider you choose. The gate checks structure, not meaning.
- It ships as its own command-line tool under the Apache 2.0 licence. The hosted API offers translation checks and string extraction (
/v1/localization/checkand/v1/localization/extract); translating itself runs in the CLI with your own provider key.

FAQ
Questions.
Can I migrate from another tool?
glossa import reads existing Inlang, Tolgee, Crowdin and Lingo configuration, and lingo works as an alias.
Which translation providers work?
