GitHub App, command line and CI

Check every change before it ships

Your AI writes code all day. Redproof checks each pull request and marks problems on the exact lines. It reads JavaScript, Python, Go, Ruby, PHP, Java and C#, mobile apps, and the Docker, Terraform and CI files around them.

rredproofCritical

Credits are added for the user id sent in the request, not the signed-in user. Anyone can top up any account.

m/redproof fix

Fix pull request #42 opened: use user.id and check the code was not used before

The GitHub App

Install it once; every pull request gets a "Redproof" check. Works on private repositories too. Code is read in memory and never stored.

On the exact line. Each issue appears on the line that causes it, as a review comment.
Quiet by design. Only the files the pull request changes are reported.
Blocks only what matters. Critical issues fail the check; everything else is a warning you can merge past.
Free: the automated checks on every pull request.
Solo $49, Team $149, Business $449 a month: an AI review of the changed files and fix pull requests within a monthly allowance. Comment /redproof fix and review the fix before merging.

Command line and CI

Run it in your project folder, or add it to any pipeline. It exits with an error when the score is too low, so a risky build never deploys.

npx redproof-cli --yes
npx redproof-cli --yes --min-score 80 --fail-on critical

GitHub Actions:

- uses: actions/checkout@v4
- run: npx redproof-cli --min-score 70 --fail-on critical

Inside your AI tool

Let Claude, Cursor or any MCP client run the check and apply the fix prompts, without leaving the editor.
