Three short demos: a behavior change, a performance regression, and a security leak that shipped undetected for seven years. Each one takes a few minutes to watch, and your engineers can run the same thing on a public repo.

Choose a demo to watch

Run it yourself

git clone https://github.com/Curtail-Inc/hello-ReGrade
cd hello-ReGrade
docker compose up -d --build
