We built a free tool that audits n8n workflows. Paste your JSON, get a report in under a minute.
It catches overpriced LLM calls, broken nodes, and runaway loops before production does. There’s also a Workflow Sanitizer to strip sensitive data before you share a workflow publicly.
We’re still testing the engine, so your feedback would genuinely help us improve it.

great tool. Saw your post on reddit. Looks very promising.
a useful audit should separate structural checks from business checks. structural checks can catch missing credentials, disconnected nodes, invalid expressions, and unsafe sharing of secrets. business checks need sample payloads that verify the workflow produces the right result, not just that every node executes. i would keep three fixtures per workflow: a normal case, an empty or partial case, and a downstream failure. run those in a dry environment, record execution time and model cost, then require a human to review the diff before production. sanitizing exported json before sharing is worth making automatic.
