Automation and integrations decision
n8n Cloud
A narrow, self-hosted workflow runner (webhooks, HTTP nodes, code steps, and logging) is realistic for a small team to build and maintain, but reproducing n8n Cloud's breadth (UI polish, 400+ nodes, templates, hosted scaling, AI credits, and enterprise features) is substantial and better justified when those needs are critical.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
Code n8n Cloud publishes itself
Not a way out of the subscription — these are the vendor’s own repositories. Worth a look for how they build, and for anything you would have to integrate with.
What a replacement has to do
- Receive trigger (webhook/schedule) → run node graph (HTTP/code/AI) → store/stream execution results → retry/alert on failure
What it still won’t have
- Hosted UI, templates and pre-built node catalogue
- Managed scaling, observability and audit/log streaming
- Built-in AI credits and assistant preview
- Enterprise features (SSO, extended retention, dedicated SLA)
- Broad community & vendor support channels
What remains hard
- Brand trust
Top 50 Github. Our 199.3k stars place us among the most popular projects.
- Brand trust
4.7/5 stars on G2.
- Infrastructure at scale
n8n handles up to 220 workflow executions per second on a single instance.

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 3 seats.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal hosted workflow runner in Node.js (Express) + Postgres + Redis + worker pool. Scope in: REST API to create/update JSON workflow graphs, webhook and cron triggers, an execution worker that runs HTTP request nodes and executes user JS/Python code safely (use a sandbox like vm2 or spawn isolated subprocesses), execution queue with Redis and BullMQ, store execution logs in Postgres, basic web UI to list workflows and recent executions, and simple retry/error notification via email. Out of scope: full visual drag-and-drop editor, 400+ built-in integrations, enterprise SSO, paid billing. Include input validation, authentication (JWT), rate limiting, CI tests for worker and API, and sane error handling and retries.
How we checked
How the score was reached

- Price verified on pricing page+3
- Hard moats found in the evidence-3
- Evidence score60
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
