ShipCheck
Summary
A pull request can look clean in review while quietly deleting the authorization check that keeps non-owners from canceling each other's subscriptions — and no diff-reader catches what was never in the diff. ShipCheck gives repositories a persistent memory of behavioral guarantees, then surfaces violations when a PR breaks them.
ShipCheck connects to GitHub, requires no configuration, and maps behaviors already encoded in your codebase — authorization logic, validation rules, API contracts, session handling — into named, protected expectations. When a future PR changes code that touches those behaviors, ShipCheck classifies the impact as preserved, introduced, intentionally changed, or violated, rather than just summarizing the diff. Historical origin tracing mines git history across implementation and test files so you know not just that a behavior broke, but when it was introduced and what evidence supported it. The tool operates as a one-shot PR scanner, not an autonomous agent, so every finding surfaces in the pull request rather than running downstream tasks on its own. Teams protecting security boundaries or API contracts in actively changing codebases are the target fit.
Bottom line: ShipCheck earns its place in repositories where authorization rules and API contracts change hands across many PRs — but teams that need it to trigger downstream actions, integrate into non-GitHub CI pipelines, or expose findings via API will hit a hard wall fast.

Pros
Sign in to edit- GitHub-native setup with no config required, so teams get behavioral regression detection active on the first PR without a separate deployment or integration project.
- Behavioral diff classification — preserved, introduced, intentionally changed, or violated — so reviewers see the impact on what the software was supposed to guarantee, not just what lines changed.
- Historical origin tracing mines git history across implementation and test files, which means you can identify not just that a safeguard broke but when it was first established and what code supported it.
- Cross-file evidence linking connects a protected behavior to its authentication boundaries, callers, helpers, and tests, so a regression in one file that affects a guarantee defined elsewhere still gets caught.
- Freemium entry point with a free tier, so individual developers can protect behavioral contracts across multiple repositories without a budget approval cycle.
Cons
Sign in to edit- GitHub is the only supported platform — teams on GitLab, Bitbucket, or any self-hosted VCS cannot use ShipCheck at all, and the only path forward is waiting for the vendor to add support or choosing a different tool.
- No API is available, so findings cannot be consumed programmatically by downstream systems, dashboards, or CI gates; teams that need behavioral regression data to block a merge automatically or feed a security audit trail must build around a gap the tool does not close.
- Behavior discovery is automated inference from existing code, not a declarative spec — if the codebase has poorly tested or undocumented contracts, ShipCheck has little to surface, and the protection is only as good as what the repository already encodes.
- The tool is not self-hosted, meaning any team operating under data residency requirements or prohibitions on third-party code scanning cannot deploy it, and the alternative is a self-hosted static analysis or SAST tool that covers some of the same regression ground.

Hidden Behavior Breaks in Pull Requests
A pull request can look clean in review while quietly deleting the authorization check that keeps non-owners from canceling each other’s subscriptions — and no diff-reader catches what was never in the diff. ShipCheck connects to GitHub, requires no configuration, and maps behaviors already encoded in your codebase — authorization logic, validation rules, API contracts, session handling — into named, protected expectations.
How it works
When a future PR changes code that touches those behaviors, ShipCheck classifies the impact as preserved, introduced, intentionally changed, or violated, rather than just summarizing the diff. Historical origin tracing mines git history across implementation and test files so you know not just that a behavior broke, but when it was introduced and what evidence supported it. The vendor states behavior discovery is automated inference from existing code.
Limitations to weigh
GitHub is the only supported platform. No API is available, so findings cannot be consumed programmatically by downstream systems or CI gates. The tool costs $15/month on a subscription model, with a free tier limited to 3 repositories, 30 behavioral AI analyses, and 10 regression tests per month during beta.
Who it is for / who should skip it
Best for individual developers managing multiple repositories, teams needing shared behavioral policies, and projects requiring contract and safeguard verification. Skip it if you need GitLab or Bitbucket support or programmatic API access for automated merge blocking.
