FlowLens - Debug, compare, and replay n8n failures

by•
FlowLens gives n8n developers one focused place to inspect sanitized execution payloads, compare successful and failed runs, save test cases, and deliberately replay corrected requests. It connects through the built-in HTTP Request node, so there is no community node to install. A free plan and live no-account demo are included.

Hi Product Hunt — I built FlowLens to shorten the most frustrating part of operating n8n workflows: moving between execution history, copied JSON, credentials, and ad-hoc webhook tools just to understand and reproduce a failure. The integration is intentionally simple. Import one of the supplied templates or add an HTTP Request node, then FlowLens gives you a sanitized execution inbox, structured comparison, saved test payloads, and deliberate replay to an approved destination. It does not replace n8n; it gives developers and agencies a focused debugging workspace around it. There is a useful free plan, and the complete live demo needs no account. I would especially value feedback from people who operate client workflows: which part of failure investigation still costs you the most time?
