Limits

Most limits are the same whatever the plan; storage and the monthly credit allowance depend on it. The plans page has the plan-dependent numbers.

Each limit has a visible consequence — a refused action, or a run that ends with a reason — so you can tell which one you reached.

Limit	Applies to	What happens
Storage	Account and one workflow	A file that would take you over is refused. Files already stored stay available and deletable.
Secrets	100 per account, 5 per workflow, 32 keys per secret	Creating one more is refused; delete an unused secret to make room.
Run duration	15 minutes per attempt	A run still working at the limit is stopped and marked failed. A resumed run starts a new attempt with a fresh 15 minutes.
Concurrent runs	2 runs you start yourself	A third is refused while the other two are running. Scheduled and webhook runs do not take one of those slots.
Webhook deliveries	60 per minute, per trigger and per account	The delivery is refused, and the sender can retry it.
AI builder conversation	10 messages	Start a new conversation to keep going. The charge is once per conversation, not per message.

Storage and the monthly credit allowance are plan features; the plans page lists them, and Billing and credits explains how a run is charged.
