FunnelSitter

For people shipping with Cursor, Lovable, Bolt, Replit, and v0

FunnelSitter watches your signup, login and checkout so you don't have to.

Uptime checks stay green while the button is gone. Paste a URL and a real browser opens that one page. No account.

The free check loads one page only. It is a quick health check of that page: HTTP status, console errors, broken links, unfinished buttons, load time, and a screenshot. It does not test signup, login, or checkout. Full flow monitoring comes with an account.

One page only. It does not test signup, login, or checkout. We ask for an email only on the result, and only if you want it sent.

Works with apps built on Lovable, Bolt, v0, Replit, and Cursor

Checkout was down for days

The homepage still returned 200. Ads kept spending. Nobody noticed until a customer said so.

An agent release broke login

The first deploy after a coding agent touched auth locked every customer out. The founder found it in production.

The signup form died quietly

Traffic arrived. The form crashed. Leads were gone for almost two weeks.

How a check actually works

The free check looks at one page. A monitor, after you prove the domain, walks the flow you describe.

  1. 01

    Paste the URL

    The free check loads that one page in a real browser. It does not sign up, log in, or check out. No account.

  2. 02

    Prove the domain is yours

    A DNS TXT record, a meta tag, or a file. Then we will watch it on a schedule.

  3. 03

    Describe the flow

    Click, fill, submit, expect. Or write one sentence and we turn it into steps.

  4. 04

    Get the failure, not a green dot

    After two failures in a row: screenshot, plain language, and a prompt for Cursor or Lovable.

Help

What does the free check do?
The free check loads one page only. It is a quick health check of that page: HTTP status, console errors, broken links, unfinished buttons, load time, and a screenshot. It does not test signup, login, or checkout. Full flow monitoring comes with an account.
Can the bot solve a captcha?
No. The bot cannot solve captchas. A step that stops on a captcha fails.
Can it finish an email confirmation?
No. Email-confirmation steps cannot be completed with example.com test addresses. Those addresses do not receive mail.
What happens to the test accounts?
Test accounts stay in your app. Each run, including a retry, uses a new example.com address so the second try does not fail with “already exists”. FunnelSitter does not delete those accounts from your product.
