Flutter ARB file checker

Drop your template (app_en.arb) and the translated ARB files together. The page reads each file's @@locale, compares every translation with the template, and reports what flutter gen-l10n or your users would hit: renamed or missing placeholders, ICU messages that do not parse, plural categories the language needs, dropped tags and missing keys.

Choose files

Drop .arb files here, or use Choose files. Your files stay in this browser tab: the page runs the same parser, checks and writer as npx shipglot check, and nothing is sent anywhere.

The locale comes from @@locale, else from the file name (app_fr.arb). The template's locale is the source locale.

Run the same checks on every pull request

The same checks as a GitHub Action, with annotations on the lines that break. The Flutter ARB CI guide has a config and workflow for this format.

name: Translations
on: pull_request
jobs:
  shipglot:
    runs-on: ubuntu-latest
    permissions:
      contents: read
    steps:
      - uses: actions/checkout@v5
      - uses: aurelien64/shipglot@v0
        with:
          fail-on: error

Translate

Hosted translation is not open yet. The checks on this page work today with no account: run the open-source gate in your project,

$ npx shipglot check

or add the GitHub Action from the Flutter ARB CI guide to check every pull request.

When hosted translation opens, it will run from your repository, not from this page. With a free Shipglot account, shipglot translate sends only new and changed Flutter ARB strings to Shipglot, writes the translations into your files with the same writer this page uses, and updates shipglot.lock. The free plan will cover projects up to 500 source keys, with translation included.

npx shipglot init        # writes shipglot.config.json for your layout
export SHIPGLOT_TOKEN=...  # from your Shipglot account
npx shipglot translate
npx shipglot check

In GitHub Actions, run it as a step and commit the result, or run it locally before you push:

- uses: actions/checkout@v5
- run: npx shipglot translate
  env:
    SHIPGLOT_TOKEN: ${{ secrets.SHIPGLOT_TOKEN }}
- uses: aurelien64/shipglot@v0
  with:
    fail-on: error

Every check has its own page with a failing and a passing example: all checks.
