Heal creates production-like local sandboxes from a codebase and runs automated end-to-end tests to find bugs, aimed at software development teams using coding agents. It also documents codebases into specs for spec-driven development and keeps sandboxes, specs, and tests in sync as code changes.

Company profile
researched Aug 2026Heal (heal.dev) builds software quality-assurance tooling that creates a production-like, locally running sandbox from a team's codebase and then exercises it with end-to-end tests to identify bugs. The company frames its product as an opinionated testing strategy rather than a general-purpose coding agent, and its stated output is a list of tests, what each test proves, and what remains broken, rather than a coverage percentage.
The product follows a four-step loop: set up a sandbox that closely mimics production so there is a realistic target to test against; scan the codebase to create or update specifications usable for spec-driven development; implement and run tests against the sandbox, recording a video of each run as proof of work; and keep the sandbox, specs and tests synchronized as the codebase changes. Heal positions itself against common failure modes it describes on its site, including staging environments that pass while production breaks due to missing dependencies such as third-party webhooks, ambiguity about which user flows constitute happy paths, and reported code-coverage figures that correspond to no end-to-end integration testing.
As of the material reviewed, Heal is operating an early-access waitlist and publishes demonstration sandboxes built on public open-source repositories, including formancehq/payments and windmill-labs/windmill, showing the number of tests run and bugs found for each.
Business model
Heal offers its sandbox-and-testing product to software teams, with access currently gated behind an early-access signup. It states that the product is free for open-source projects, with credits offered to open-source maintainers who contact the company via its social account.
Traction
Public demonstration sandboxes include formancehq/payments, with 186 tests run and 11 bugs found, and windmill-labs/windmill, with 121 tests run and 2 bugs found.

Market position
Heal describes itself as not an agent but an opinionated testing strategy, emphasizing production-like local sandboxes, end-to-end coverage of real integration paths, and video proof of executed tests, in contrast with reported code-coverage percentages that it says do not reflect tested integration paths.
Technology
Heal spins up a fully functional local sandbox that closely mimics a production environment, including services that the company says are otherwise untestable. It scans the codebase to generate or update specifications, implements and executes end-to-end tests against the sandbox, records video of test runs as evidence, and re-synchronizes the sandbox, specs and tests as the codebase evolves. Its interface presents an architecture view with nodes for features, tests, sandbox, data catalog, agent and system under test, including scope boundaries.
Go-to-market
Access is distributed through an early-access signup on the company website. Heal seeds interest by publishing live sandboxes for well-known open-source repositories with published test and bug counts, and by offering free credits to open-source projects that reach out through its social channel.
Software engineering teams that use coding agents and need end-to-end verification of changes, including maintainers of open-source repositories.
