Open-source Unito alternatives

n8n is a workflow automation platform for connecting apps, moving data between them and triggering actions without writing a full integration from scratch. Workflows are built on a visual canvas, and when a step needs more logic you can drop in JavaScript or Python and use npm packages. It is often compared with Zapier and Make, but the source is public and it can run on your own infrastructure.

Recent versions put a lot of weight on AI. You can build multi-step agents and LLM workflows that call OpenAI, Anthropic, Google or open-source models, add human approval steps, and inspect what happened afterward. The project advertises over a thousand integrations and a large library of ready-made workflow templates, and you can extend it with your own nodes.

n8n is distributed under a fair-code model: the Sustainable Use License, plus a separate enterprise license for additional features. The code is always visible and can be self-hosted, for example with Docker, but it is not an OSI-approved open-source license, so commercial redistribution is restricted. A managed cloud edition is available if you would rather not run it yourself.

Activepieces is an open-source replacement for Zapier, positioned as an all-in-one AI automation tool. Automations are built from pieces, which are type-safe TypeScript npm packages, and the interface is meant to work for both technical and non-technical users. The topics also describe it as an alternative to n8n. The repository metadata lists the license as Other.

Pieces that are contributed to the project automatically become available as MCP servers, so LLM clients such as Claude Desktop, Cursor and Windsurf can use them. The platform includes native AI pieces for working with different providers, an AI SDK for building agents inside the builder, and human-in-the-loop steps that delay execution or require approval. Developers can set up tools, then others in the organization use the no-code builder. It can be self-hosted, including in network-gapped environments, and supports branding customization.
