One run, one locale
de: 2 translated, 12 unchanged, 359 tokens (318 in, 41 out)
A CLI, an SDK, a local Studio and an MCP server, all reading the same lock file.
Translate
Only 4 of 28 translations are new or changed, so only 4 go to your provider.
$ npx @verbatra/cli translate
de: 2 translated, 12 unchanged, 359 tokens (318 in, 41 out)
fr: 2 translated, 12 unchanged, 366 tokens (322 in, 44 out)
total: 725 tokens (640 in, 85 out)
2 succeeded, 0 partial, 0 failedCheck
exit 1
The check exits 1 while a locale is missing keys. It needs no API key, so it runs on every pull request.

Agents
Register the MCP server for the project, and the agent can read status and fix translations. Tools that spend provider tokens stay off until you allow them.

Features
From the first string in your source code to the reviewed translation in production.
A local dashboard over your project: browse every locale, work through the review queue and edit values in place.
Export an Excel workbook, CSV, TSV or XLIFF for a translator and import it back. Imported values stay protected from later machine runs.
Scan your code for translation calls and add the new keys to the source locale before anyone translates them.
Keep a watcher running in development, and every change to the source locale is translated as you save.
Generate TypeScript declarations for your keys and message arguments, so a typo in a key fails the build.
Doctor checks the setup without an API key, and an estimate sizes a run before it costs anything.
Short answers, each with the docs page that goes deeper.
Yes. Verbatra is free and open source under the MIT license (opens in a new tab), and you pay only your provider for the keys that changed; estimating cost sizes a run first.
Anthropic, OpenAI, Gemini, DeepL, Google Cloud Translation, OpenCode, OpenAI-compatible, and LibreTranslate. Set one in provider, or none when only people translate; the providers page covers each.
Only to the provider you configure, when a command translates; there is no telemetry. Keys stay in environment variables, and data handling lists what each provider receives.
Yes. verbatra check exits 1 while a locale has missing or stale keys, with no API key needed; the GitHub Action runs it on pull requests.
It is a CLI that runs on your own committed files, not a hosted platform. The comparison page checks it against other tools, with sources, including where they are stronger.
Before you spend a token
This path is for a project that already has locale files, and neither step needs an API key.
