Startup · AI-augmented testing
Keep your UI in check with tests that heal themselves.
Your team ships fast, but who verifies what customers actually see? Nerro Labs catches pixel-level regressions and automatically adapts when your interface changes.

The testing gap
Manual QA can't keep up with how fast you ship
Writing brittle selectors and eyeballing screenshots doesn't scale. Nerro Labs replaces both with deterministic, self- maintaining visual AI.
Manual & brittle testing
- Tests break on every CSS change
- Hours spent debugging flaky locators
- Bugs reach production anyway
- QA can't keep pace with releases
Nerro Labs visual AI
- Tests adapt automatically to UI changes
- Zero time spent on locator maintenance
- Pixel-level regressions caught pre-merge
- One suite, every browser and device
Visual AI
See every pixel that changed, instantly
Nerro Labs compares renders against a visual baseline and flags exactly what moved, resized, or disappeared — not just that a screenshot looks different.
Cross-browser
One test, every browser and device
Run the same suite across Chrome, Firefox, Safari, and Edge, on desktop, tablet, and mobile viewports, without maintaining separate test code for each.
Self-healing
Tests that fix themselves
When a locator breaks, Nerro Labs matches the element by visual and structural similarity and updates the test automatically — no PR required.

Is Nerro Labs a new company?+
Yes — we're an early-stage AI visual testing startup based in Kathmandu, Nepal, built closely with our first group of design-partner teams.
How is this different from Selenium or Playwright?+
Playwright and Selenium are the engines that drive a browser. Nerro Labs sits on top, adding visual AI comparison and self-healing locators — it works with your existing framework rather than replacing it.
What counts as a 'visual diff'?+
Any pixel-level change between a baseline render and the current one — a shifted button, a broken layout, a missing icon — flagged with the exact region highlighted.
Do I need to rewrite my existing tests?+
No. Nerro Labs integrates as a plugin for your existing Playwright, Cypress, or Selenium suite — most teams add visual checks to existing tests in an afternoon.
Is there a free plan?+
Yes, every account starts with a free tier that covers small projects and open-source repositories.
