n8n-nodes-flowproof

An n8n community node that validates a workflow export imports cleanly — before you ship it to a client, publish it, or trust one you downloaded. It catches the exact things that break shared templates on import:

• 🔑 leaked credentials embedded in the JSON (must never ship)
• 🧩 missing / community nodes not installed on the target instance
• ⬆️ version drift (a node exported from a newer n8n than the importer runs)
• 🪢 broken connections and structural corruption
• ⚠️ deprecated nodes & parameters

Runs entirely inside your n8n. No API, no network, no credentials — your workflows never leave the instance.

Operations

• Check — full diagnostic report (importable, fidelity_score, blockers, manual steps, required community packages, per-issue detail).
• Verify — a pass/fail verdict + the blockers, designed to gate a deploy (toggle Fail Node on NOT-Importable to stop a run).

Why trust the verdict

FlowProof's verdicts are arbitrated against a live n8n import — in testing against 20 real workflows from 3 sources, the check matched the live importer with 0 mismatches. This node re-implements that same logic in TypeScript and a CI parity test asserts it agrees with the reference engine on every fixture.

The free CLI version (Python, MIT) lives at https://github.com/AkuchiS/flowproof. FlowProof Pro goes further: it repairs the workflow and hands you an import-ready file + a content-hashed "FlowProof Checked" certificate + a client-ready handover.
