n8n

n8n is an open-source workflow automation platform that combines a visual node-based editor with code capabilities. It allows users to build complex automations and AI agents by connecting 500+ integrations, writing JavaScript or Python directly in workflows, and implementing human-in-the-loop approvals. The platform supports self-hosting for data privacy or a cloud version for convenience. It fits developers, IT operations, and solopreneurs needing to automate business processes, orchestrate AI agents, or integrate legacy systems without vendor lock-in. Typical use cases include employee onboarding, security incident enrichment, CRM lead automation, and backend prototyping.
