Show HN: NUA an agent that tests for product correctness

QA built for agentic coding.

Nua finds bugs before your users do, reproduces the ones they report, and turns every fix into a regression test you never think about again.

Ship fast. Break nothing.

The problem

The expensive part of a bug isn't the fix. It's finding it and reproducing it.

TodayWith Nua

A bug report lands with no steps and no context. A senior engineer loses half a day just making it happen again.

Nua reproduces it first: steps, a screen recording, console errors, network requests. Your dev starts at the fix.

Dozens of reports a day, one or two days to turn each around. Feature work waits.

Every report shows up already reproduced, with a fix prompt ready to paste into Claude Code or Cursor.

The worst bugs are the ones you can't reproduce. They stay open for weeks and come back at the worst time.

If it happened, Nua can show it happening. And once it's fixed, a regression test keeps it fixed.

How it works

A bug report goes in. A ready-to-paste fix comes out.

The bug bash

Nua doesn't wait for bug reports.

It explores your app the way a real user would, plugged into your PRDs, tickets, and customer calls. That's how it finds the bugs nobody thought to write a test for: functional bugs, UX issues, and visual drift from AI-generated components.

Found the AI-generated table that overflows on a 13-inch screen.

Finding bugs used to look like this.

Rooms of people, checking by hand.

Then rooms of testers, clicking by hand.

Then scripts that broke every release.

AI made shipping features easy. What customers feel is the last 20 percent. Getting from 80 to 100 is the moat now.

This is how it's done now

It never comes back

Every fix becomes a test that keeps it fixed.

When your app changes, the tests adapt on their own. Nothing you fixed comes back.

Where it pays off

What your team gets back.

Under the hood

Nua tests your app like someone who works there. It reads what your team already wrote.

Get out of the bug business.

We're onboarding dev teams now. Setup is a login, not an integration project. Codebase access is optional. If bug reports are eating your roadmap, we should talk.
