Never ship an automation you haven't watched run
Flow simulation runs a real record through your automation — before it can touch a customer.
Everyone has an automation horror story. The 3am email blast. The 'Hi {firstName}' to four thousand people. The loop that assigned one poor rep every lead in the database.
The common thread: the flow was tested in production, on customers.
Rehearsal, not hope
Solstral's simulator takes any real record and walks it through your flow: which branch it takes, which emails it would receive, which fields would change, where it would exit. Nothing sends. Nothing writes. You just watch.
The other guardrails
Simulation is the headline, but the quiet protections matter as much: goals that exit people the moment they convert, chain tracking that makes infinite loops structurally impossible, business-day timing, and execution windows so customer-facing steps only fire inside hours you chose.
