QA built for agentic coding.

You ship faster with AI. Your QA doesn't.

Nua is the QA that keeps up. It finds bugs before your users do and turns them into regression tests automatically, so coverage grows as fast as you ship.

How it works

Two ways Nua keeps your app working.

Exploration
  1. 01 / Crawl
    Nua crawls your app and maps every state it can reach.
  2. 02 / Probe
    Then it walks the app as the people who use it. Your coding agent can't catch what it wrote. Nua is independent, so it can.
  3. 03 / Evidence
    Every finding comes back with a screen recording, repro steps, and the console and network trace that caused it.
Regression
  1. 04 / Locked in
    It becomes a regression test and a ticket in Linear or Jira.
  2. 05 / Your own tests
    Add your own: drop in a PRD, describe it in plain English, or record yourself clicking through the flow.

Under the hood

It knows your product, and every version you ship.

What it knows

It reads what your team already wrote.

What it covers

Built for configurable apps. Feature flags, plans, roles and tenants all change what a user sees, and your default login only ever shows you one of those versions.

For domains with their own rules, Nua goes deeper with knowledge built for that field.

The problem

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

One bug, start to finish. The fix takes the same 45 minutes either way. Everything in front of it is what you are actually paying for.

Waiting and triageMaking it happen againWriting the fix
The queue

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

Every report arrives already reproduced.

The worst ones

The bugs nobody can reproduce stay open for weeks, then come back at the worst time.

If it happened, Nua can show it happening.

Finding bugs used to look like this.

Load-testing a new rail bridge
Locomotives as the proof of safety
Edison at the test bench
The first actual bug, taped into the logbook
Test flight, Cape Canaveral
Human computers checking the math
Rooms of people, checking by hand
Verifying runs on the mainframe floor
Crash testing before the road

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

No tradeoff

Stop choosing between shipping fast and shipping working software.

Senior time back

The half-day repro hunt is the most expensive part of a ticket. Nua does it.

One product team

PM, dev and QA used to be three roles. AI made them one. Nua is how that team ships.

Get out of the bug business.

We're onboarding teams shipping with AI now. Setup is a login. Codebase access is optional. If bugs are eating your roadmap, book a call and we'll show you what Nua finds in your app.
