Middleman is a hosted webhook proxy that captures, transforms, and forwards HTTP requests.

Templates reshape JSON bodies on the way through, so Middleman can act as an adapter between incompatible systems — no glue code needed.

How it works

Features

• Capture — every HTTP request your endpoint receives is recorded with full headers and body.
• Inspect — view captured requests and responses in the dashboard's history pane.
• Transform — reshape JSON request bodies with a simple template language.
• Forward — relay each request to a target URL you configure.
• Guest mode — try it with a temporary endpoint that lasts 7 days, no signup needed.

Paid plans add retries, replay, response mocking, and more — see pricing.
