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.
Fast path
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 a webhook gateway with routing, delivery attempts, retries, replay, transformations, and integrations.
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.

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 Actions and 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?
The practical distinction is scope: FastHook manages inbound webhook capture, routing, delivery attempts, retries, and replay, while RequestCatcher is strongest for simple real-time request capture in a browser.
Can FastHook capture webhooks like RequestCatcher?
Yes. Unlike a basic RequestCatcher capture workflow, FastHook sources preserve request evidence and can immediately create 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. 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 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?
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.
