# Heal

> Find reproducible bugs by running your application in a sandbox

Heal runs an application in a sandbox to find defects that depend on actual behavior. It sets up the product and its supporting services, explores workflows, and investigates functional bugs, security weaknesses, and performance problems. Findings include reproduction steps and a failing test, so developers can examine the evidence and check whether a fix resolves the issue. Teams can use it before a release or periodically across an existing product, alongside their usual code reviews. External services can be mocked or emulated to test failure conditions without relying on a live payment or messaging integration. A discovered defect can then be handed to a coding agent and verified through the supplied test.
