Webhook Alternatives
RequestCatcher Alternative
RequestCatcher is a lightweight way to create a subdomain and watch requests arrive in real time. FastHook is the alternative when that request stream needs routing and recovery.
This page is for developers who have outgrown a browser-visible request catcher and need event history, destinations, retries, replay, filters, and transformations.
Fast path
Create a FastHook source, connect it to one or more destinations, then use events, attempts, retries, and replay to operate the webhook flow after the first test succeeds.
What is RequestCatcher
RequestCatcher creates a subdomain for testing applications, webhooks, HTTP clients, and API calls, then forwards incoming requests to the browser in real time.
It targets developers who want a simple, temporary request catcher without configuring a full webhook gateway.

Why users search for alternatives to RequestCatcher
Users search for a RequestCatcher alternative when a simple inspection page is not enough for team-owned webhook delivery.
- Pricing may not be the issue; the bigger concern is production feature depth.
- A browser-forwarded request stream is simple, but not a complete delivery pipeline.
- Missing retries, replay, transformations, and multi-destination routing can block production use.
- Vendor or tool lock-in is low, but operational history can be missing when tests are temporary.
- The learning curve is tiny for capture, then jumps when teams need durable routing.
- Free or lightweight usage is ideal for quick tests but not long-lived provider endpoints.
FastHook vs RequestCatcher
| Capability | RequestCatcher | FastHook |
|---|---|---|
| Webhook Capture | RequestCatcher captures HTTP requests sent to generated URLs and exposes request details. | Built in through stable source URLs with request, event, and attempt history. |
| Webhook Testing | Strong for quick sender tests, payload discovery, and temporary endpoints. | Supports source URLs, mock destinations, CLI delivery, replay, and receiver validation. |
| Webhook Debugging | Good for inbound inspection; production delivery evidence depends on the product and plan. | Links inbound request data, routed events, transformed payloads, delivery attempts, and responses. |
| Retry Logic | Retry policy is usually not the primary model for request-bin style tools. | Connection-level retry rules for recoverable destination failures. |
| Replay Events | Captured requests may be replayed or resent when the product supports it. | Replay individual events or recovery windows after a downstream fix. |
| Filtering | Rules or custom actions may exist, but routing branches are usually lighter than a gateway. | Connection filters can match headers, body fields, query params, and paths. |
| Transformations | Payload shaping often depends on scripts, custom actions, or external automation. | JavaScript transformations can reshape payloads before delivery. |
| Multi Destination Routing | Forwarding is possible in some flows, but fan-out routing is not the core workflow. | One source can fan out through multiple connections to separate destinations. |
| Google Sheets | Usually requires custom actions, a script, or a separate automation platform. | First-class destination for appending webhook events as rows. |
| Slack | Usually requires custom actions, a script, or a separate automation platform. | First-class destination for Slack channel notifications. |
| Telegram | Usually requires custom actions, a script, or a separate automation platform. | First-class destination for Telegram chats or channels. |
| Email capture or notifications may exist, but email delivery is not the main routing model. | Gmail and SendGrid Email destinations are available for human workflows. | |
| API Access | API access varies by product, account, and plan. | REST API and CLI operations for sources, destinations, connections, events, and retries. |
| Team Features | Enough for tests; deeper team workflows usually need paid or production features. | Team-scoped resources, dashboard workflows, event evidence, and shared routing objects. |
| Pricing | Often attractive for low-volume tests, with limits around privacy, retention, requests, or teams. | Best evaluated by routed event volume, retention needs, destinations, and recovery workflows. |
| Ease of Use | Very easy when the job is just creating a temporary URL. | Designed around source, destination, connection, then test request. |
When RequestCatcher is the better choice
- You need the simplest possible request catcher.
- You are testing a client and watching requests live in a browser.
- No team workflow, retention, or routing is required.
- The endpoint is temporary and not part of production.
When FastHook is the better choice
- You need stable webhook source URLs and delivery history.
- You want to route requests to services, people, and storage.
- You need replay and retry after failures.
- You want filters and transformations before delivery.
- You need a product that teammates can use for operations.
How to migrate from RequestCatcher to FastHook
- Create a FastHook source to replace the temporary RequestCatcher subdomain.
- Send the same curl or provider test payload to FastHook.
- Create destinations for the receiver, chat channel, email, Sheet, or archive.
- Add filters or transformations only after the raw request shape is confirmed.
- Use FastHook events and attempts to validate delivery behavior.
- Switch the provider URL when the FastHook flow is stable.
Frequently Asked Questions
Is FastHook a good RequestCatcher alternative?
FastHook is a good RequestCatcher alternative when the job is webhook routing, debugging, replay, retries, and delivery to multiple operational destinations. RequestCatcher remains a better fit when the primary need is simple real-time request capture in a browser.
What is the main difference between FastHook and RequestCatcher?
RequestCatcher is a lightweight live request viewer, while FastHook is a webhook gateway with routing, delivery attempts, retries, replay, transformations, and integrations.
Can FastHook capture webhooks like RequestCatcher?
Yes. FastHook sources provide public webhook URLs and preserve request evidence. The difference is that captured requests can immediately become routed events with filters, transformations, retries, replay, and destination attempts.
Does FastHook support webhook retries and replay?
Yes. FastHook supports retry rules for failed destination deliveries and replay workflows for recovery after a receiver is fixed. This is one of the main reasons teams compare FastHook with RequestCatcher.
Can FastHook route one webhook to multiple destinations?
Yes. A FastHook source can connect to multiple destinations through separate connections, so each branch can have its own filters, transformations, retry behavior, and delivery history.
Does FastHook send webhook data to Google Sheets, Slack, Telegram, and email?
Yes. FastHook includes destinations for Google Sheets, Slack, Telegram, Gmail, SendGrid Email, Discord, Cloudflare R2, AWS S3, Twilio SMS, Twilio WhatsApp, HTTP, CLI tunnels, and mock receivers.
When should I keep using RequestCatcher?
Keep using RequestCatcher when its core strength matches the project: simple real-time request capture in a browser. FastHook is meant for teams that want the webhook stream itself to become a managed routing and recovery layer.
How hard is it to migrate from RequestCatcher to FastHook?
Migration is usually straightforward when you inventory existing webhook URLs, copy provider secrets, recreate destinations, and test with a parallel FastHook source. The main work is turning a temporary request catcher URL into a stable source connected to real destinations.
Does FastHook fully replace RequestCatcher?
Not always. If RequestCatcher is being used for simple real-time request capture in a browser, it may remain useful. FastHook replaces the parts related to reliable inbound webhook capture, routing, debugging, transformation, retries, replay, and integrations.
How should I compare pricing for FastHook and RequestCatcher?
Compare the cost of a simple free catcher against the operational need for retention, team access, retries, replay, and production destinations.
