About n8n

n8n (pronounced “n-eight-n”) is a low-code / visual workflow automation platform that lets you connect multiple apps, services, and APIs via nodes, triggers, and actions. You can self-host it or use their managed service, add custom code (JavaScript, TypeScript, HTTP requests) where needed, and build complex branching logic, loops, and integrations. Its “fair-code” license lets internal use be open, while commercial redistribution is restricted.

Key Features

Visual node-based workflow editor

Over 400+ integrations / nodes

Triggers (webhooks, cron, polling) and action nodes

Support for custom JavaScript / code nodes

Branching, conditional logic, loops, error handling

Self-hosting or n8n Cloud

Replay / debugging and execution logs

Support for AI / LLM workflows within nodes (via integrations)

Queue / worker mode for scale

Pros

Very flexible and extensible (you can insert custom code)

Rich ecosystem of integrations out-of-box

Visual interface lowers barrier to entry

Can self-host to avoid vendor lock-in

Supports advanced logic (loops, branching, error handling, parallelism)

Has AI / LLM integration features built in

Cons

Complex workflows can become messy graphically

You may need infrastructure overhead when self-hosting (workers, queues, etc.)

Some advanced capabilities (scaling, concurrency) require understanding of internal modes

License is not fully “open source” in the sense of unrestricted commercial use (fair-code / SUL)

Debugging in some edge cases of custom code nodes or API integrations can get tricky
