Early access · Lovable first, more builders soon

Catch what breaks in your Lovable, Bolt, Replit or Cursor app before your users do.

Bugwhisper tests your app like a real user after every publish. When something breaks, you get a plain-English answer and a fix you can paste straight into Lovable. Then it proves the fix worked.

Product demo: Bugwhisper tests four user flows on a notes app. “Save a note” fails because the database rejects new notes, even though the app shows “Saved!”. Bugwhisper explains the cause in plain English, gives a fix prompt to paste into Lovable, re-checks after publishing, and confirms the fix works.

The silent failure

Your app says “Saved!”
It didn't save.

This is the bug that hurts most, because nothing looks wrong. Your users think it worked, and you find out weeks later, if at all.

What your user sees

Meeting notes for Friday
Save note
Saved!

Looks perfect.

What actually happened

  1. Button pressed
  2. App sent the note to your database
  3. Database refused it: no rule allows adding notes
  4. App ignored the error and showed “Saved!”

The note is gone. So is your user's trust.

What Bugwhisper watches

The breakages that cost you users

Data that never saves

Forms that look like they worked but silently lose what people typed. Usually a database permission rule.

Sign-up & login failures

New users stuck at the door, or never getting the confirmation email.

Blank pages after a publish

You changed one thing. A page you didn't touch went white.

Broken integrations

Payments, emails or outside services quietly stop answering.

Hidden errors

Errors your users never report, but that quietly stop buttons from working.

Checks after every publish

Bugwhisper notices each time you publish and re-tests the flows that matter, so a new change can't quietly break an old feature.

How it works

From “something's off” to proven fixed

  1. 1

    Paste your app's link

    Bugwhisper suggests the flows that matter, like sign-up, login and saving. You approve them in plain English.

  2. 2

    It tests like a real user

    A real browser clicks through your app on a schedule and after every publish.

  3. 3

    You get a clear answer

    What broke, why, and how serious it is, with the evidence behind every sentence.

  4. 4

    Fix it, then prove it

    Paste the fix into Lovable and publish. Bugwhisper re-tests and only says “fixed” when it is.

Why not just ask the AI?

Guessing vs. knowing

Asking Lovable to “fix it”

  • It can't see what your users see
  • It guesses at the cause
  • The fix may break something else
  • You find out from an annoyed user

With Bugwhisper

  • Tests your live app like a real user
  • Pinpoints the cause with evidence
  • Gives Lovable an exact, specific fix
  • Re-tests to prove it worked

You stay in control

Bugwhisper never edits, publishes or changes settings in your app.

Evidence, not guesses

Every answer points to the screenshot or error it's based on.

Careful with your data

Tests that create data run only with your OK, and are labelled “[Bugwhisper test]”.

Questions

Good to know

Do I need to know how to code?

No. Bugwhisper is made for founders who build with AI. Answers are in plain English and fixes come as prompts you paste into Lovable. The technical details are there if you want them, tucked away by default.

Will Bugwhisper change my app?

Never. It doesn't edit, publish or change settings. You decide whether to apply each fix.

Will it create test data in my app?

Only for tests you approve, like checking that sign-up or saving works. Every test record is labelled “[Bugwhisper test]” so it's easy to find and remove.

Does it work with Bolt, Replit or Cursor apps?

We're starting with Lovable so diagnoses are as accurate as possible. Bolt is next. Join anyway and tell us what you use; it helps us decide.

What will it cost?

Early access, including your health check, is free. Later there'll be a free plan and paid plans for continuous monitoring, and you'll always see prices before paying anything.
