n8n
Source-available workflow automation that combines visual building with custom code and AI agents.
n8n is a workflow automation platform built for technical teams that want the speed of no-code without giving up the flexibility of code. You build automations on a visual canvas by connecting nodes for over 400 apps and services, and can drop into JavaScript or Python whenever a step needs custom logic. Its AI capabilities let you build agents whose reasoning is traceable step by step on the canvas, making it a popular choice for RAG pipelines, IT operations, security automation, and lead workflows. Because the source is available and the platform is self-hostable, teams with strict data requirements can run n8n entirely on their own infrastructure, while n8n Cloud offers a managed option. With one of the most popular repositories on GitHub, the community contributes thousands of ready-made workflow templates.
Pros
- Self-hostable, so sensitive data never has to leave your infrastructure
- Fair-code license with a free community edition for self-hosting
- Far more flexible than typical no-code tools thanks to code steps
Cons
- Steeper learning curve than consumer automation tools like Zapier
- Cloud plans meter workflow executions, which can need planning at scale
