Both can open a browser. They start from different places.
Checkly is known for synthetic monitoring that engineers script, including browser checks and API checks. FunnelWatch starts from a sentence and a URL, then keeps the replay cheap.
Checkly
Checkly fits a team that already writes checks the way they write tests, and wants those checks next to the rest of their monitoring.
FunnelWatch
FunnelWatch fits a person who shipped with an AI app builder and does not want to maintain a Playwright suite. You describe the path, prove you own the domain, and get an alert with a prompt when a step breaks.
| Topic | Checkly | FunnelWatch |
|---|---|---|
| Who writes the check | An engineer, as code, in the product built for that workflow. | You, in a sentence, plus the URL. A model writes the script once. Replays do not call the model when the path passes. |
| Browser checks | A core part of what Checkly is known for. We are not claiming they only ping URLs. | Paid plans replay in a browser. The free plan does not. Production checkout stops on the payment page. |
| The alert | A failed synthetic check for the person who owns the monitor. | The failed step, a screenshot, and a prompt aimed at Cursor or Lovable. |
| Safety limit | Their own rules for what a script may do. | Funnels run only on a verified domain. Real card numbers are rejected. A live Stripe secret key is refused. |
