Webhook Alternatives
FastHook as a 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.

turning a temporary request catcher URL into a stable source connected to real destinations
What RequestCatcher is good at
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.

Where FastHook fits
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.
The core difference between FastHook and RequestCatcher
RequestCatcher is a lightweight live request viewer, while FastHook is an automation platform with app Workflows and webhook routing, delivery attempts, retries, replay, and transformations.
RequestCatcher is strongest when: simple real-time request capture in a browser
When to choose FastHook
- 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.
When to choose RequestCatcher
- 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.
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 or archive and Actions for the chat channel, Gmail, or Google Sheet.
- 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.

Compare the cost of a simple free catcher against the operational need for retention, team access, retries, replay, and production destinations.
Frequently Asked Questions
Is FastHook a good RequestCatcher alternative?
For this webhook-focused comparison, evaluate FastHook for routing, debugging, retries, replay, and supported downstream Actions or Destinations. Check RequestCatcher against the specific requirements of your process, including simple real-time request capture in a browser.
What is the main difference between FastHook and RequestCatcher?
This page compares the webhook use case with RequestCatcher's focus on simple real-time request capture in a browser. FastHook provides webhook capture and delivery controls alongside app Workflows. Verify the capabilities your process requires before treating the products as interchangeable.
Can FastHook capture webhooks like RequestCatcher?
FastHook Sources receive webhooks and preserve request evidence. Events can feed Workflows or delivery routes with filtering, transformations, retries, replay, and destination attempts. Check sender authentication, response requirements, and payload compatibility for your use case.
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. When moving a RequestCatcher workflow to FastHook, one source can connect to multiple destinations through separate branches with independent filters, transformations, retries, and delivery history.
Does FastHook send webhook data to Google Sheets, Slack, Telegram, and email?
Yes. Beyond RequestCatcher, FastHook can deliver to 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 capabilities meet requirements that you have not reproduced elsewhere. Review simple real-time request capture in a browser and verify app operations, execution behavior, deployment needs, and any specialized features before migrating.
How hard is it to migrate from RequestCatcher to FastHook?
Effort depends on the existing configuration, app operations, credentials, data shapes, and failure behavior. Inventory these first, rebuild supported routes or Workflows, and test with isolated destinations before cutover. The focus of this guide is turning a temporary request catcher URL into a stable source connected to real destinations.
Does FastHook fully replace RequestCatcher?
A complete replacement requires verifying every required capability. FastHook supports webhook delivery tools and app Workflows, but this comparison does not establish parity with all RequestCatcher features. Test the full business outcome and any specialized requirements.
How should I compare pricing for FastHook and RequestCatcher?
Start with both current pricing pages, then model expected RequestCatcher usage against FastHook by request volume, retention, team access, destination count, recovery features, and engineering work that remains outside either subscription.
