Requex

Requex - The all-in-one webhook and API development platform

Requex brings together the tools developers usually cobble together from multiple services - webhook inspection, mock servers, and workflow automation - into a single, unified platform.

Webhook Inspection & Debugging Instantly generate unique webhook URLs and capture every incoming request in real time. Inspect headers, payloads, query parameters, and metadata in a clean interface, so you can see exactly what third-party services like Stripe, GitHub, or Shopify are sending you. Replay any captured request against your own endpoints to test fixes without waiting for the event to fire again - no more guessing why a webhook failed. Requex also supports webhook forwarding, which can send one webhook to multiple webhooks.

Schema Drift Detection Requex goes beyond passive logging. It learns the structure of your incoming payloads and alerts you when a provider silently changes their webhook format — catching breaking changes before they break your production integrations.

Mock API Servers Spin up mock endpoints in seconds to simulate APIs that don't exist yet or aren't available in your environment. Define custom responses, status codes, and delays so your frontend and backend teams can build and test in parallel without waiting on real services.

Workflow Automation Turn incoming webhooks into automated pipelines. Route, filter, and transform requests, chain multiple steps together, and forward data to any destination - all with reliable, queue-backed execution. It works like a lightweight n8n alternative

Whether you're debugging a flaky integration, mocking a dependency, or building event-driven automation, Requex replaces tools like webhook.site, RequestBin, Mockoon, and Beeceptor with one coherent platform built for modern API development.
