Get started
Start with one repo.
We plant realistic bugs in your code one at a time and run your own tests against each. It's free during early access, and every repo gets the full report: your score, and every miss with the test that would catch it.
- You send the repo.Public repos need nothing. For a private repo, we reply with how to give us read-only access. Nothing is ever pushed to it.
- We freeze the bug list first.The bugs are written without reading your tests, and the list is hashed before anything runs.
- You get a private link.The report has your score and every miss with the file, the line and the test to add.
Before you send it
- We take a few new repos each week, in the order they arrive. If your suite can't run as it is, for example because it needs paid API keys, we'll tell you rather than guess.
- Private repos: nothing runs until you give us read-only access, and your code stays in a private copy on our CI. Security and data has the detail.
- Real bugs come first. If a run turns up a genuine bug in your shipped code, we tell you separately, whether or not you go further.
- Nothing is published. We never publish a result that names your project without your consent.
- It runs every month. Last month's bugs are planted again, to prove your new tests hold. Early access has the detail, and the sample report shows what a report looks like.
