Deploy. Invoke. Receive.

Every workflow gets a URL.

Every call runs the workflow and sends the result back when it's done.

FAQ.

Do I host anything?
No. You deploy a file and call a URL. The rest runs on our side.
What if a step fails?
It retries, up to the count you set on the step. If that runs out, the run fails and your webhook receives a run.failed event.
Do steps run in parallel?
Yes. A step waits only for the steps listed in its needs. Steps that need nothing from each other start together.
Can runs overlap?
Yes. Every call is its own run, and runs go in parallel: 10 at a time on Hobby, 100 on Pro.
How is it billed?
Credits are US dollars. A model call costs the provider's price plus 20%. A run costs a tenth of a cent.
