Baseline analysis
Focus on new issues without getting slowed down by pre-existing.
Approvals
Override with a click when a PR needs to be merged in a hurry.
Triage rules
Customize blocking issues based on path, rule, and category.
No CI setup required
Analysis runs on our cloud, allowing you to be up and running in minutes.
