When sharing development URLs with teammates or QA, verify each service's current browser and API behavior on the selected plan.
ngrok provides local tunnels with traffic inspection, verification, and replay. SDNBros provides a persistent event workflow with provider detection, delivery diagnostics, and replay-safety guidance.
When a webhook delivery fails, SDNBros doesn't just show you a 500 status. It analyzes the response body, correlates with known provider error patterns, and tells you why it failed — "Signature verification failed: clock skew of 47 seconds" or "Endpoint returned 503: upstream database connection refused." No more guessing.
Before you replay a failed event, SDNBros checks whether it's safe. A payment_intent.succeeded might create a duplicate charge. A customer.updated is safe to retry. You get a clear verdict before clicking replay.
SDNBros automatically identifies the webhook provider (Stripe, GitHub, Shopify, Slack, Twilio, and 22 more) from request headers and payload structure. Events are tagged, grouped, and searchable by provider without any configuration. ngrok treats every request identically.
