About two minutes to a real finding. No account until you want one.
Download the binary for your machine from the latest release, check it against the checksum beside it, and put it on your path. Builds for macOS on Apple silicon and Intel, Linux on x86_64 and arm64, and Windows.
Run peko init and then peko lint --all. Every finding names the rule, the file, and the line, and says what to change. Nothing leaves your machine.
The GitHub Action runs the same engine on a pull request, and findings land on the line they belong to through Code Scanning. Pin the version.
Everything above is free and stays free. An account adds rejection diagnosis and the audit tier, which reads the code with a model and judges the guidelines a file cannot settle on its own.
