# Built-in checks

Meticulous can detect non-visual regressions and report them before a pull request is merged.
When a check fails, the author of the PR has to acknowledge the result in Meticulous before the pull request can proceed.
Every built-in check can be configured to alert only — reporting its findings as warnings that never fail the status check — so you can adopt a check without blocking pull requests on it.
Available built-in checks:

- [Accessibility](/docs/built-in-checks/accessibility) — catch new accessibility violations introduced by a PR
- [Network requests](/docs/built-in-checks/network-requests) — catch PRs that make your app issue meaningfully more network requests
- [React component renders](/docs/built-in-checks/react-component-renders) — catch PRs that make your React components re-render meaningfully more

More will be added soon. A Meticulous admin can turn these on for your project.

> **info: Closed beta: we're looking for design partners**
> Meticulous checks are in closed beta and not enabled by default. The feature is still evolving, so we're looking for design partners to try it out, share feedback, and help shape it before it's generally available. Reach out to the Meticulous team at [support@meticulous.ai](mailto:support@meticulous.ai) and we'll turn it on for your project and work with you directly on your use case.
