n8n
n8n is a visual workflow automation platform that connects apps, APIs and AI models in node-based flows. It is mainly used to automate business processes, integrate services and orchestrate AI agents, in the cloud or on a self-hosted server.

Who it's for
Best for
Teams wiring many apps and internal APIs into one auditable workflow
Developers who want to self-host automations on their own server
Not for
Non-coders who need a working automation without scripting or paid lessons
Careful buyers who need a guaranteed way back into a lost cloud account
Features
Visual workflow builder
Flows are built from nodes on a canvas, with code dropped in where it is needed. Opening any step shows what it does.
Agent visibility and approvals
Agents can be watched working live or reviewed in past runs inside the same workflow, with structured inputs, outputs and human approval steps.
Self-hosting and source access
Deployment is available on-prem or with Docker to keep data in a private environment, and the source code sits on GitHub alongside a hosted version.
Step-level retries and errors
Errors are spotted at a glance and a single broken step can be re-run on its own instead of restarting the whole workflow.
Documentation built into the flow
The workflow itself serves as documentation, so no separate docs or handover write-ups are needed.
What users say
Pros
- A failed run can be followed node by node on the canvas, so the broken step is obvious instead of guessed.
- Runs on a Raspberry Pi or a cheap VPS, so workflows stay up around the clock without a cloud subscription.
- Flows set up once keep running unattended for months, including a five-node missed-call text-back that catches leads.
- A flow that reads a calendar and writes an AI summary takes about five minutes to assemble.
- Rebuilt from Zapier, the same automations fail less often and the price model is far easier to justify.
Cons
- Once a workflow grows large, the canvas turns into a tangle of nodes that is hard to trace and debug.
- A run can finish green while producing nothing, with scanned PDFs returning empty fields and no error fired.
- Marketed as no-code, but real workflows need scripting, code nodes or paid lessons before anything works.
- Workflows sit apart from the codebase, so refactoring the project means rechecking and fixing automations separately.
- Credits get spent fixing a workflow that broke on its own, so failed runs still cost money.
- A cloud account tied to an expired sign-up email is lost for good, and answers to recovery emails arrive about a day apart.
