Activepieces charges per flow, Zapier per task. One is open-source and self-hostable, the other connects to far more apps. Here's an honest, side-by-side look at which fits your automations, and what switching really involves.
Activepieces and Zapier both let you automate work by connecting your apps, but they charge in opposite ways. Zapier charges per task, meaning each action that runs. Activepieces charges per active flow, no matter how often it runs. Zapier connects to far more apps. Activepieces is open-source and can run on your own server. Which one wins depends entirely on how much your automations run and how many apps you need. Flows vs Zaps: What's the Difference in Name?
Most Activepieces vs Zapier comparisons start with a simple fact: both tools do the same basic thing, they just use different words for it. In Zapier, an automation is called a Zap. In Activepieces, it's called a flow. Both start with a trigger (the event that kicks things off) and then run one or more actions (the steps that follow).
Activepieces is often described as an open-source Zapier alternative, and that label captures the real split: it does what Zapier does, but with an open, self-hostable foundation underneath. The differences that matter aren't in the name. They're in pricing, app selection, AI features, and who each tool is built for. How They Charge You: The Biggest Difference This is where the two tools split most sharply, and it's the thing most likely to decide which one is cheaper for you.
Zapier charges by the task. A task is one action that finishes successfully. If a Zap has three actions and runs 200 times a month, that's 600 tasks. Your bill goes up as your automations run more often. Activepieces charges by the active flow. You pay a flat amount per flow you have switched on, and it can run as many times as you want without the price changing. A flow that runs 100 times and a flow that runs 100,000 times cost the same.
The plain-language takeaway: if your automations run a lot, Activepieces tends to get cheaper, because you're not paying per run. If you have only a few automations that don't run often, Zapier's model can work out fine, and its free plan lets you test first. App Selection: Where Zapier Pulls Ahead Zapier connects to far more apps than Activepieces does. Zapier links to thousands of services, one of the largest libraries of any automation tool.
Activepieces connects to a few hundred apps, which covers the common ones (email, CRMs, Slack, spreadsheets) but is more likely to be missing a less common tool you use. If your automation depends on a specific or unusual app, check that both tools support it before choosing. This is the area where Zapier's head start matters most. Control and Ownership: Where Activepieces Pulls Ahead Activepieces is open-source, which means its code is public and you can run it on your own server if you want.
