n8n

n8n is a workflow automation platform that lets technical teams connect apps, APIs, and services into automated pipelines through a visual, node-based editor. It pairs no-code convenience with the option to drop into custom JavaScript or Python, and it has grown into a popular tool for building AI agents and LLM-powered workflows.

It is designed for developers, IT teams, and technical operators who want automation they can extend, version, and self-host for privacy and control. Because the source is openly available, many run n8n on their own infrastructure, avoiding per-task pricing and keeping sensitive data inside their environment.

n8n offers a free self-hosted community edition alongside paid cloud and enterprise plans that add collaboration, scaling, and support. Founded by Jan Oberhauser in 2019 and based in Berlin, the company has become one of Germany's most valuable software startups.
