Zerocheck navigates your app like a real user, protecting existing flows and generating new tests from your PR diff. After merge, it continuously monitors production.
Your team ships 3x faster with AI.
But your testing can’t keep up.
Teams ship features in hours with Claude Code, Codex, Cursor, but can’t manually test every PR.
Your integration tests break with every redesign, and bugs reach your customers weeks before you even know about them.
of CI failures are flaky tests, not real bugs.

Features
Push a PR. Zerocheck reads the diff, traces which flows your changes touch, and writes the tests for them.
See change-aware testing →Every test records the browser. You see what happened at each step, with screenshots, step trace, and repro notes posted on the PR.
See SOC 2 evidence automation →Selector-based tests break when you change the UI. Zerocheck interacts visually, using accessibility trees instead of DOM paths.
See zero-to-CI setup →Payment webhook failed
Stripe returned 502 on /webhooks/checkout. Last success: 42m ago.
Zerocheck reruns these flows on a schedule. If checkout breaks due to a completely unrelated change, you find out before you lose customers.
See production monitoring →How it works
Connect GitHub and point Zerocheck at staging. No CI pipeline work required.
Zerocheck generates a new test suite by scanning your app. Review and edit it, or add your own.
Zerocheck traces what your changes affect, including downstream dependencies, generates tests for those flows, and runs the entire suite. Recording, screenshots, and step trace added to every PR as a comment.
After merge, your flows keep running against production on a schedule.

Feature flag rollout broke the control group's checkout flow
OAuth redirect looped after identity provider update
Payments dependency bump crashed checkout for 50% of users
Unit tests catch code issues. They miss a broken checkout, or a CSS change that hides the buy button. That manual click-through is the test nobody wrote.
Wiring it into CI, writing selectors, and fixing them when the UI changes costs 20+ hours a week.
You get a recording, screenshots, and step trace posted on the PR while you’re still in the code. Not a checkmark. What actually happened. When something fails, you see the recording of what went wrong and the exact step that broke.
Playwright MCP gives your coding agent a browser. You still write the test logic, handle assertions, and wire it into CI yourself. Zerocheck reads your diff, generates tests, runs them, and posts results with a recording. MCP is a tool. Zerocheck is a workflow.
| Manual clicking | Playwright DIY | QA hire | Managed QA | |
|---|---|---|---|---|
| Time to coverage | Instant (but no coverage) | 2–6 months | 1–3 months | 2–4 months |
| Weekly maintenance | Your time, every PR | 20+ hrs/week | Their full-time job | Vendor’s team |
| Annual cost | $0 in tools | $0 framework + eng time | $150K+ salary | $48K–$96K/yr |
| When UI changes | You click again | Selectors break | They fix the selectors | Vendor fixes it |

Detailed comparisons
Zerocheck reads the PR diff, writes tests for the affected flows, and runs the full suite. You don't author tests manually, maintain selectors, or spend 20 hours a week on upkeep.
See change-aware testing →Go from zero tests to a green CI pipeline in your first afternoon. You don't set up a framework, design a selector strategy, or hire for it.
See zero-to-CI setup →Stop hunting for screenshots before every audit. Every test run generates a timestamped, commit-bound JSON evidence artifact tagged with your SOC 2 controls.
See SOC 2 evidence →Fifteen minutes. One of your real PRs. You watch the browser navigate your app and see exactly what passed and what broke. If it doesn’t catch something useful, you’ve lost nothing.
