n8n
Source-available workflow automation with native AI agent building blocks.
Free self-hosting; paid cloud plans; source-available.
n8n is a source-available automation platform in the business category that pairs a visual, node-based editor with the flexibility of code. You build workflows by connecting nodes on a canvas, and because n8n can be self-hosted, teams keep full control over where their data lives and avoid per-execution pricing.
What it does
n8n has become a favourite for AI automation thanks to native agent nodes built on LangChain concepts. You can wire up an AI Agent that chooses tools, keeps memory across steps and calls different model providers, then embed it in a larger workflow alongside databases, APIs and messaging apps. With more than 400 integrations, a universal HTTP request node and JavaScript or Python code nodes, almost anything is reachable. Reusable sub-workflows, webhooks and scheduling keep larger projects organised and maintainable.
Who it’s for
n8n suits developers, technical teams and businesses that want automation without vendor lock-in or metered execution costs. Self-hosting is free but takes some setup, while managed n8n Cloud offers a hosted option for those who prefer not to run their own servers. Its blend of visual building and real code makes it especially strong for AI-heavy, custom workflows.
