heal.dev takes a different angle on AI code review: instead of reading the diff, it runs your product in a sandbox that replicates production - real API, real Postgres, test data - and hunts for behavior bugs, runtime vulnerabilities and performance issues.
Each reported issue comes with the failing test that proves it: the site shows an example where an expired discount code displays as applied, then checkout charges full price, proved by a generated spec file. Hunts come in behavior, security and performance modes, each with quick, standard and deep tiers, and fixes can be handed to a coding agent.
Vendor claims to attribute: the homepage quotes users saying it found bugs their code review missed, and links to a vendor-published benchmark comparing its findings against code review. A free trial is offered with no credit card required.
