Activepieces is an open source automation platform from Germany. Flows are built without code from hundreds of pieces, its name for integrations, and AI steps can be added anywhere in a flow. The core is released under the MIT licence.
You can self-host Activepieces or use the hosted cloud, which has a free plan, and the open licence means the code can be audited and extended by anyone. That makes it a European alternative to the American automation services for teams that want no-code automation without giving up control.
