No signup · no upload · no guesswork

Start with evidence from your own repository

forthwith check

Run it before you create an account. Review concrete defects with file locations, fix them yourself, or continue into Forthwith's guarded repair and translation workflow.

Private by default

The check runs on your machine. It does not contact the Forthwith API or require an account.

Find real defects

Catch missing keys, malformed files, placeholder mismatches, plural gaps, duplicates, and untranslated values.

Stay in control

Repair findings manually, or initialize a project and use the paid --fix workflow for supported issues only.

Run your first check

Free evidence. Paid only when you choose.

Check locally. Fix precisely. Ship every locale.

The free check stands on its own. When you want Forthwith to do the work, continue with the same repository and pay only for the repair or translation you approve.

From a founder

What customers say

Forthwith made adding translations to my site fast and genuinely painless — a few languages and the whole thing was live. The output felt natural and register-appropriate, and it respected my do_not_translate list across 250+ strings without me having to babysit it.
