n8n 

Flexible AI workflow automation for technical teams is the line n8n puts on its page. The About calls it a workflow automation platform that mixes AI with business process work, so people can hook up any app or API and keep both code and no-code. It ships under a fair-code license, can run on your own servers, and has a community of builders. You can start small in the visual builder, then add JavaScript or Python when you need more control, and connect anything to everything. It is privately held and lists backing from Sequoia, Felicis Ventures, Firstminute Capital, Harpoon Ventures and others, plus Kevin Hartz and Ilkka Paananen as individual investors. Founded in 2019, it sits in Berlin. The site is n8n.io.
