Start with your app, review the candidate journey tests, and put the approved ones in the PR path.
“I inherited 10,000 lines of code with zero tests. No documentation. No comments. Just spaghetti code from a developer who quit 3 years ago… By day 4, I thought about quitting.”

“I deployed a new checkout flow on Friday afternoon at 4:47 PM. After 6 minutes Slack exploded - payment processing broke and customers couldn’t complete purchases.”
DEV Communitysource
“In the rush to get stuff out, time-consuming things get skipped like user testing, automation, analytics, monitoring, and manual testing… These bugs will keep annoying people using and relying on the software.”
The Pragmatic Engineersource
42% of testers don’t feel comfortable writing automation scripts
41% of committed code is now AI-generated - more code shipped, less confidence
Zero-to-coverage onboarding takes 2–6 months with traditional tools
Enterprise tools cost $100K+/year. Open-source frameworks are free but demand weeks of infrastructure setup and ongoing maintenance. Growth-stage companies often sit between those two options.
The maintenance pattern is common: a team picks Playwright, writes 10 tests, a UI refactor breaks half, the fixes lose priority, and within 3 months they’re back to manual smoke testing.
New engineering lead joins a 20-person startup. The app has 40K lines of code and zero E2E tests. They evaluate Playwright: Day 1 is npm install + config. Day 2 is writing a login test - but OAuth redirects don’t work. Day 3: first test runs, selectors are brittle. Week 2: CSS refactor breaks everything. Week 4: 5 tests exist, 3 engineers are frustrated, momentum is dead.
Start with the production URL. Discovery scans the app, identifies key flows, and saves suggested tests in the dashboard. Engineer reviews and approves the tests that should run. Connect GitHub when the approved suite is ready to run on PRs.
Point Zerocheck at the production app engineers already ship
Find the user journeys your team cannot afford to break
Review readable tests instead of writing selector-heavy scripts
Run approved generated and human-authored coverage on PRs
Other tools document their own platform controls. Zerocheck produces JSON evidence from your executed application tests.
Guard the only code path where a bug is measured in lost dollars per minute.
Magic links and onboarding flows fail quietly. Zerocheck can run approved browser checks after you provide a safe login path.
Playwright is a browser automation library. You still need to build CI integration, write selectors, handle auth, and keep the suite alive. Zerocheck gets you from an uncovered app to reviewed journey checks on GitHub PRs without owning a selector maintenance project.
Zerocheck directly explores your app to find candidate journeys and saves suggested tests for review. Coverage expands when you approve generated tests from discovery and PR diffs.
Keep them. Zerocheck adds intelligence on top: change-aware test generation, visual interaction that survives UI changes, and PR comments with evidence. Your existing tests still run.
QA Wolf deploys a managed team to write and maintain tests for you. Zerocheck is for lean teams that want journey coverage, PR evidence, and production monitoring while keeping engineers in control of what becomes approved coverage.
Get coverage on the flows customers will notice when they break, without turning testing into a quarter-long infrastructure project.
