Features

Everything you can't see right now

Your pipeline is a black box. KiwiMediator opens it — without touching your handlers. Completely free.

📋

Handler Registry

See every registered handler at a glance — request type, response type, assembly, registration lifetime.

⏱️

Execution Timings

Average, min, and max execution time per handler. Spot slow handlers before your users do.

🔗

Pipeline Behavior Order

See exactly which behaviors wrap each request and in what order. No more guessing the pipeline.

🔴

Live Request Log

Watch requests flow through the pipeline in real time. See what fired, when, and how long it took.

Exception Tracker

Capture and display unhandled exceptions per handler with stack trace — without polluting your logs.

🛡️

Dev-only by default

Inspector endpoint is disabled in Production automatically. Zero risk of accidental exposure.
