CatchHook vs. ngrok
ngrok exposes and governs live services; CatchHook keeps webhook capture and debugging available even when localhost is offline.
ngrok is a connectivity and API gateway platform. Its agent exposes a live service, while its cloud Traffic Inspector can search captured traffic, retain full captures for the plan window, and replay or edit requests. Traffic Policy can verify supported webhook signatures before forwarding. CatchHook instead gives the provider a persistent hosted endpoint that captures whether or not a local process is online, then supports provider-aware inspection, replay, Replay Cases, Actions, alerts, email ingress, and optional fast-ack local relay.

Feature Comparison
| Feature | CatchHook | ngrok | Notes |
|---|---|---|---|
| Expose a live local service | This is ngrok's core job across HTTP, TCP, TLS, gateway, and ingress use cases. | ||
| Persistent hosted webhook capture | CatchHook receives and stores the request even when no local relay is connected. | ||
| Traffic inspection and search | ngrok Traffic Inspector searches cloud captures; CatchHook searches retained endpoint history. | ||
| Editable request replay | Both edit and replay. CatchHook adds provider identity regeneration, supported re-signing, and replay-risk guidance. | ||
| Webhook signature verification | ngrok verifies supported providers in Traffic Policy. CatchHook records verification alongside the captured event when an endpoint secret is configured. | ||
| Provider-aware debugging context | CatchHook carries supported-provider event, setup, signature, and replay context through the UI, API, and MCP. | ||
| Replay Cases with assertions | CatchHook turns a captured delivery into a rerunnable case with deterministic assertions. | ||
| API gateway and Kubernetes ingress | ngrok serves substantially broader production ingress and policy jobs. |
Where CatchHook Stands Out
Choose ngrok to expose or govern a running service
It is the broader connectivity platform, with multiple protocols, Traffic Policy, ingress, identity, and production gateway controls.
Choose CatchHook for always-on webhook capture
The provider-facing endpoint persists independently of localhost and retains the event for later search, replay, comparison, or local delivery.
Preserve the provider-specific fix
CatchHook Replay Cases combine a captured request, deterministic assertions, and run evidence after the handler is repaired.
