Which one should you pick?

n8n

Workflow automation with hundreds of integrations and AI nodes. Its Fair-code license is source-available rather than open-source: the code is public, but commercial use is restricted. Read the license before you build on it. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Activepieces

No-code automation, an open Zapier alternative. Its MIT license is permissive — free to use commercially, embed and modify. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Huginn

Build agents that monitor and act on the web for you. Its MIT license is permissive — free to use commercially, embed and modify. Because it is self-hostable, your data can stay entirely on your own infrastructure.

Switching from Zapier without the drama

1. Export your data from Zapier first — most tools above can import standard formats.
2. Run your top pick in parallel for a week or two before committing; self-hosted options can be tried locally in minutes.
3. Migrate one team or one project at a time, keeping the old account read-only until everything checks out.
