The free cloud plan is a plan, not a trial. No card, unlimited flows, one user, and a daily credit allowance — a fresh batch each morning rather than a monthly bucket, so running out today never eats into tomorrow.
Run out and nothing breaks. The pricing page says your flows stay switched on and runs past the quota simply don't go through until credits refresh the next day. A mistake on this platform costs you a day, not a month.
You would start paying when the free daily allowance stops being enough, or when a second person needs to be in the workspace. Plus and Team are flat monthly plans with much larger credit allowances, and runs beyond the allowance are billed per credit. AI steps cost more credits the more capable the model is, and a paid plan lets you plug in your own AI account to bring every AI step back down to the cost of an ordinary run.
Worth checking before you commit anything real: the Activepieces cloud currently runs in one data region, Germany. If your work has to sit somewhere else, running it yourself is the answer rather than the cloud.
First step: sign up at activepieces.com, open the template library rather than a blank canvas, and run somebody else's finished flow once before building your own.
