The agent says the work is done. But would you know if it wasn't?

AI agents like Claude, Cursor, Lovable, Bolt, and Replit are good at writing code. They tell you it's done — but after the app ships, you have no clear way to tell whether it actually does what you asked. Reading the code shows what is supposed to happen, not what happened. Logs are hard to read and don't answer the question. Meanwhile, real users are already using it.

  • The agent says it's done. It can't tell you what happened after that.

  • The code shows what should happen, not what did.

  • Logs don't tell you which users were affected.

What Viewo does

Your app sends Viewo a record of important things as they happen — a signup, a payment, a file export. Viewo runs checks against those records and, when a check finds something wrong, shows you the exact case in plain English: what happened, which user, and when.

How Viewo works

We review every request by hand — you'll get a confirmation email within 24–48 hours. Once you're in:

  1. 1
    Connect your agent.

    You paste a setup message into the AI agent that built your app. You don't write any code yourself.

  2. 2
    Walk through your app.

    The agent updates your app to report to Viewo and builds a page where the reports show up. As you click through, the reports appear on that page next to your app — so you can confirm Viewo is seeing what it should.

  3. 3
    Pick the bugs to catch.

    You and the agent agree on what would count as a bug. The agent writes each one as a check. Viewo runs the checks around the clock and shows you anything they catch.

What it can catch

Anything that shows up in your app's events. Some examples:

Permissions & data access

  • A customer downloaded another company's private report.
  • A free user used the export feature.
  • A non-admin opened the admin panel.

Money & access

  • A customer charged twice within an hour.
  • A paid customer still locked out 60 seconds later.
  • A cancelled account still had access a minute later.

Things that didn't complete

  • A signup with no welcome email 60 seconds later.
  • A password-reset link neither used nor expired.
  • An order with no matching payment record.

What Viewo can't see

A quiet check is never a clean bill of health — it means Viewo has caught nothing, not that nothing happened. Viewo also tells you when it has gone blind: if your app stops sending an event it was watching, Viewo flags that as silent; if a check was never tested on a sample, Viewo marks it as unproven. It shows you the gaps instead of hiding them.
