FlowMux

FlowMux is a web app (with an optional lightweight desktop agent) for integration teams who are tired of brittle, hard-to-debug system-to-system workflows. It captures real integration traffic (HTTP, webhooks, and queue messages) from selected services, redacts sensitive fields, and lets you replay the exact payloads into staging or a sandbox endpoint to reproduce failures. It also versions “contracts” (schemas + required fields + example payloads) per integration and flags breaking changes when a payload drifts from what downstream systems expect. The product focuses on observability + reproducibility rather than trying to replace your iPaaS. Expect pushback from security and platform teams: you’ll need strong redaction, encryption, and audit logs to be taken seriously. If you can’t earn trust here, you won’t get deployed.
