What our shortlists say about the one we picked.
Best for: Teams wanting scanning inside the IDE and pull requests
It earns a place because it scans without a build, in seconds to minutes, so the check fits inside the developer's own loop and not a nightly job. That suits teams of any size where developers own their fixes. If source code privacy is a hard rule for you, ask exactly where your code is processed, since it runs as a cloud service.
