n8n

n8n is a workflow automation and AI orchestration platform that lets you visually connect apps, APIs, and AI models to build complex automations, with the option to self-host or use the cloud. It is positioned as a flexible, developer-friendly alternative to Zapier/Make with fair-code licensing, deep customization, and strong AI-native features. n8n is an open, extensible automation tool where you build workflows from “nodes” (triggers, apps, code, AI, databases, etc.), then run them on schedules, webhooks, or events to move data, call APIs, and orchestrate AI agents.

Core features
Visual workflow builder with 400+ native integrations and generic HTTP, webhook, and database nodes.
​Built‑in JavaScript and Python code nodes, npm/PyPI imports, and an expression editor for dynamic logic.
​70+ AI nodes across LLMs, embeddings, vector DBs, OCR, speech, and vision to build RAG flows and AI agents.
​Advanced debugging with node‑level logs, partial re-runs, test data replay, and branch merging.
​Self-hosting with RBAC, SSO/SAML, Git-based versioning, audit logs, and isolated environments for teams.
​
Key tools it offers
AI nodes & agents: LLM chat/completions, embeddings, vector DB nodes (Pinecone, Qdrant, etc.), speech-to-text, OCR, and tools for building multi-step AI agents and RAG pipelines.
​Forms & webhooks: Built-in form builder and webhook triggers to capture leads, intake data, and kick off workflows without extra tools.
​Workflow templates & marketplace: 1,200+ official templates plus thousands of community workflows you can import and adapt.
​n8n Cloud & self-hosted: Fully managed cloud or free Community Edition you can run on your own server/Docker.
​Git Control & environments (Business/Enterprise): Git-based workflow versioning, promotion between dev/stage/prod, and queue-mode scaling.
​
Benefits for users
For founders & growth teams: Automate lead capture, enrichment, email sequences, and reporting without buying multiple SaaS tools.
​For ops & engineering: Replace brittle scripts with maintainable, observable workflows that still allow custom code where needed.
​For AI/product teams: Experiment with AI features (chatbots, summarization, RAG, agents) quickly and later harden them into production workflows.
