Activepieces

Activepieces is an open source no-code automation platform for connecting apps and running workflows without writing code. It sits in the same category as Zapier and Make, but deploys on your own infrastructure and does not charge per task or per workflow. With 22.5k GitHub stars, it is one of the most actively developed self-hosted alternatives in this space.

The flow builder uses a visual canvas where you chain triggers and actions together into a workflow. Triggers fire on a schedule, on a webhook, or on an event from a connected app. Actions cover the standard operations each integration supports: create a record, send a message, update a row, post to an API. Branches and loops handle conditional logic and iteration without dropping into code. For steps that do require custom processing, a code piece accepts JavaScript or TypeScript directly inside the flow.

The AI piece connects to OpenAI and other LLM providers as a first-class workflow step. You can classify incoming data, summarise text, extract structured fields from unstructured content, or generate responses as part of a larger automation, without building a separate AI pipeline.

Activepieces also offers an embedded SDK for SaaS builders who want to give their own users access to automation without building the integration infrastructure themselves. The white-label capability makes it worth considering not just as an internal automation tool but as a product feature.

The commercial tier covers SSO, audit logs, and custom branding. For self-hosted teams that do not need those features, the MIT core is fully functional.
