A trigger is the Checkly event that starts a workflow. An action is what FlowMattic does in Checkly from a step.
| Event | What it does | Type |
|---|---|---|
| Webhook Alert Channel | Triggers when a check fails, recovers, or experiences a performance degradation. | Trigger |
The builder keeps the order you think in: connect the app, choose what starts the workflow, add what should happen.
Add a Checkly connection under Connects and reuse it in every workflow. Credentials stay in your WordPress database.
Start from a Checkly event, or from a WordPress event, a form, a webhook, a schedule or any of the 918+ integrations, then capture a sample so later steps can map real fields.
Chain Checkly actions with Router, Filter, Iterator and Delay, test each step against captured data, then switch the workflow on.
Each example pairs Checkly with an app it is often used with. Build any of them on the canvas, or start from the workflow library.

30-day money-back guarantee Unlimited workflows and runs Self-hosted
It is self hosted and wordpress based. So you can effectively run this on any shared hosting with unlimited tasks. And new integrations are constantly being added. It's crazy how valuable this tool is.
The software works really well, and the team is adding integrations constantly, so I'm positive it eventually will catch up with Zapier. The flows are very easy to create and if you have any doubt, the team will give you great support.
