Why switch
Why teams move off Zapier
Self-hosting is not only about saving money. These are the reasons people make the switch.
Own your data
Your data lives on a server you control, not on Zapier's infrastructure. No surprise policy changes and no lock-in.
No per-seat pricing
Most self-hosted alternatives to Zapier are free to run for as many users as your server can handle; source-available ones may cap usage, so check each license. A small VPS often costs less than a single subscription.
Customize and extend
Read the code, add plugins, connect it to your own tools and automate it through open APIs. When you need a feature, you can build it or fund it.

What is the best open-source alternative to Zapier?
Activepieces is the most popular open-source alternative to Zapier, with 24,913 GitHub stars. Huginn and Node RED are also strong choices. Compare features, license and recent activity to find the best fit for your team.
Is there a free alternative to Zapier?
Yes. 6 of the 7 apps on this page are open source; 1 is source-available. The open-source ones are free to self-host without per-user fees; source-available licenses add conditions such as user caps, limits on hosted use or a paid license for production, so read them before you commit. You only pay for the server, and a small VPS is usually enough for personal use or a small team.
Can I self-host an alternative to Zapier?
Yes. n8n, Activepieces and Node RED ship a Docker image, so you can run them on a home server or VPS with Docker Compose in a few minutes. Your data then stays on hardware you control.
How do I migrate from Zapier?
Start by exporting your data from Zapier, then check the import options of the app you pick, since many projects ship importers for popular formats. Run both side by side for a week before you switch so nothing is lost.
