UltraHook Alternative — Free Webhook Forwarding Without the CLI
UltraHook is a webhook forwarding service that routes incoming webhooks to your localhost via a registered subdomain. It requires a Ruby gem install, an API key, and a command-line process that must stay running during development. WebhookWhisper provides the same forwarding capability with no install, no Ruby dependency, and a real-time inspection UI.

Why Developers Switch from UltraHook
1. Zero install — no Ruby, no gem
UltraHook requires Ruby and the ultrahook gem: gem install ultrahook. If you are not a Ruby developer, adding a Ruby dependency to your development environment just to forward webhooks is friction. WebhookWhisper runs entirely in the browser — no gem, no language runtime, no PATH setup.
2. Real-time inspection UI
UltraHook is a pure forwarding tool — it relays requests to your localhost but gives you no visibility into what was received. WebhookWhisper captures every incoming request and shows it in a browser UI with full headers, formatted body, and timing. When a webhook fails, you can see why without adding logging to your handler.
3. 35+ one-click provider test payloads
UltraHook does not include test payloads. WebhookWhisper lets you fire authentic Stripe, GitHub, Shopify, Slack, and 30+ other provider payloads with one click — no real account or real event needed to test your handler.
4. Retry logic
If your local server is not running when a webhook arrives, UltraHook drops it. WebhookWhisper retries the forwarding with backoff — you can start your server after the fact and still receive the event.
FAQ
Does WebhookWhisper require me to register a subdomain?
No. WebhookWhisper generates a permanent HTTPS URL for you automatically on free account creation — no subdomain registration or DNS configuration needed.
Does WebhookWhisper work with any webhook provider?
Yes. WebhookWhisper accepts any HTTP POST request and forwards it to your target URL. It is not limited to specific providers, though it includes pre-built test payloads for 35+ popular providers.
What happens to forwarding if I close the browser?
On the free plan, active forwarding is session-based. On Pro, forwarding rules persist and events are queued while you are offline, then delivered when you reconnect.
