What Webhook.site is good at

Webhook.site generates unique URLs and email addresses so developers can inspect HTTP requests, webhook payloads, headers, query strings, and bodies without building a receiver.

It also supports forwarding, retries, replay, scripts, and automation through Custom Actions. Both products cover more than request inspection; compare the specific response, delivery, and integration behavior you need.

Where FastHook fits

Start with a free request bin or website form. Continue in the dashboard when you need response rules, delivery, or automation.

Build a website form with choice groups, file uploads, and rich text; create its receiving address in the builder, preview it, and copy or download the HTML.
Save a temporary bin to your account while keeping its URL and captured requests.
Configure Source responses with JSON, text, or XML; dynamic rules can match the method, path, query, headers, or body and set the response status, headers, and body.
Use Source proxy mode to forward a request and return the upstream HTTP response to the sender.
Route one Source to multiple Destinations with independent filters, transformations, and retry rules.
Inspect request traces and delivery attempts, replay requests with optional changes, and save reusable test fixtures.
Forward deliveries to localhost with the FastHook CLI, or build sequential Workflows with connected-account Actions.

The core difference between FastHook and Webhook.site

Both products capture webhooks, build website forms, and support forwarding and automation. FastHook connects request bins and form submissions to Sources, Connections, delivery attempts, and Workflows. Webhook.site combines its HTTP, email, and DNS inbox with Custom Actions. Their response handling and specialized features differ.

Webhook.site is strongest when: request inspection with email and DNS capture, plus Custom Actions for forwarding and automation

FastHook vs Webhook.site: feature comparison

Capability	Webhook.site	FastHook
Free HTTP request inbox	No-signup URL with method, URL, query, headers, and body inspection. Free URLs expire after seven days and stop accepting requests at the 100-request limit.	No-signup request bin with method, path, query, headers, and body inspection. Temporary URLs expire after seven days; the tool shows the expiration time.
Access to captured requests	Free inbox data is accessible to anyone who knows the URL identifier. URLs associated with a paid account are protected by login by default.	Reading a public bin requires a separate read token. Knowing the receiving URL alone does not grant inbox access. Keep the token and any link containing it private.
Keep a test URL	Associate a URL with a subscribed account.	Save a public bin to your account, keeping its URL and captured requests under normal retention.
Website form builder	Drag and drop form components, enter a Webhook.site URL, and copy HTML for your website. Process submissions with Custom Actions.	Build and preview forms with text, choice groups, dates, files, and a full rich-text editor. Create the receiving address in the builder, copy or download HTML, and show a thank-you page after successful submission. Continue with FastHook Workflows.
Custom HTTP responses	Default response settings and synchronous Modify Response Custom Actions.	Source responses support JSON, text, XML, and conditional status/header/body rules. These are configured in the dashboard, not in the public bin.
Proxy and localhost	Cloud forwarding and a CLI that can return the localhost response to the sender.	Source proxy mode returns an upstream HTTP response. CLI Destinations deliver requests to localhost; they do not provide the same synchronous response path.
Retries and replay	HTTP Request retries and replay of Custom Actions.	Connection retry rules, delivery attempts, request replay with optional modifications, and saved test fixtures.
Automation	Custom Actions, conditions, scripts, loops, and schedules.	Workflows with connected-account Actions, conditions, transformations, Code, loops, and schedules.
Search and export	Search request content and headers; CSV export is available with a subscription.	Request filters and identifier search, plus API access. No equivalent body/header history search or built-in CSV export.
Email and DNS capture	Generated email addresses and DNSHooks alongside HTTP URLs.	The request bin captures HTTP requests. Connected email integrations are separate from a disposable email or DNS inbox.

Build a website form with FastHook

The free Form Builder creates HTML you can embed on your own website. Configure up to 20 fields, test the preview, and receive submissions at your FastHook Source.

Create a receiving address directly in the builder, or paste an existing FastHook Source URL. A newly created temporary address lasts seven days; save it to your account for ongoing use.
Choose fields: text, email, phone, number, password, long text, a checkbox, dropdowns with single or multiple selection, radio groups, checkbox groups, dates, times, local date/time, range sliders, colors, hidden values, and single or multiple file uploads. Add headings, text blocks, and submit, reset, or plain buttons.
Configure labels, field keys, help text, placeholders, default values and selections, required fields, minimums, maximums, steps, text length, and textarea rows where applicable. Edit choice labels and values, use inline choice groups, and allow an Other answer for radio and checkbox groups. Required checkbox groups need at least one selection. Set file-type hints for the file picker.
Enable rich text for long answers: headings, fonts, sizes, colors, alignment, lists, indents, links, images, tables, YouTube/Vimeo embeds, and special characters. Paste formatted text or raster images; use undo/redo, search and replace, HTML source, preview, print, and fullscreen. Formatted answers are sent as sanitized HTML.
Duplicate and reorder fields with drag handles or Up/Down controls. Edit the form title and button text, add CSS class names, and choose Minimal, Modern, Dark, Terminal, or unstyled output. The builder saves the configuration in this browser so you can resume editing.
Preview and test your form, then copy the embed code or download the HTML. Forms submit directly to the Source; file uploads use multipart encoding. Rich text and interactive choice features use JavaScript. Successful submissions open the FastHook thank-you page.
Inspect submitted fields and download captured attachments in FastHook. Connect the Source to delivery routes or Workflows when you want to send submissions to your other apps.

When to choose FastHook

You want a free request bin without signup, with an option to save the same URL to your account.
You want to build an embeddable form, collect formatted messages and files, and send submissions into FastHook Workflows.
You want request inspection, dynamic Source responses, proxy mode, saved fixtures, and delivery attempts in one platform.
You need to forward the same webhook to multiple destinations with separate rules.
You want retries and replay after a destination outage.
You need provider Actions such as Slack, Telegram, email, Discord, SMS, or WhatsApp.
You want local testing, staging, and production to share the same source-connection-destination model.

When to choose Webhook.site

You need email capture alongside webhook capture for a test.
You need DNSHook capture, a built-in CSV history export, or search across request content and headers.
You rely on synchronous Custom Actions to calculate the HTTP response, or on a response delay for timeout tests.
You need the Webhook.site CLI to return a localhost response to the original sender, or require its Enterprise SSO and custom domains.

How to migrate from Webhook.site to FastHook

Create a free FastHook request bin without signing up for an initial HTTP capture test.
Send a sample payload to FastHook and compare headers, body, query params, and path with the Webhook.site request.
Save the bin to your FastHook account to keep its URL and captured requests, or create a separate Source for production.
Use sequential Workflows with connected-account Actions for app integrations. Use Destinations for HTTP, CLI, PostgreSQL, SendGrid, R2, and S3 delivery.
Move forwarding logic into FastHook connections, filters, and transformations.
Run both URLs during a short validation window if the sender allows duplicate endpoints.
Switch the provider webhook URL to FastHook and use events, attempts, retry, and replay for ongoing operations.

FastHook vs Webhook.site pricing considerations

FastHook's public request bin is free to create without signup. For ongoing use, compare each product's current plans by request volume, history retention, automation usage, team access, and specialized features. Saving a bin preserves its URL but does not promise unlimited payload retention.

Frequently Asked Questions

Can I create a free request bin without signing up?

Yes. Open FastHook's request bin tool, select Create request bin, copy the URL, and send a webhook. You can inspect the request without creating an account.

How long does a free request bin URL stay active?

FastHook temporary request bin URLs expire after seven days, and the tool displays the expiration time. Webhook.site free URLs also expire after seven days and have a 100-request limit. URL expiration and stored-request retention are separate considerations.

Can someone read my requests just by knowing the receiving URL?

For a FastHook public bin, inbox access requires a separate read token. The receiving URL accepts submissions but does not itself grant read access. Keep the token and links containing it private. After saving the bin to your account, use the authenticated dashboard.

Can I build a form without creating a request bin on a separate page?

Yes. Open Form Builder and create the receiving address there, or use an existing FastHook Source URL. Add fields, test the preview, and copy or download the HTML. Temporary addresses expire after seven days unless saved to your account. Use a Source that accepts form submissions without authentication; proxy mode must be off for the built-in thank-you redirect.

Can I keep the same URL when I sign up?

Yes. Use Save this request bin to move it into your FastHook account while keeping the URL and captured requests. Normal data-retention policies still apply.

Does FastHook already support custom responses and proxy mode?

Yes. In the dashboard, Sources support custom and conditional HTTP responses, including status, headers, and body. Source proxy mode can return an upstream server's response. These settings are separate from the public request bin.

Do both products support retries, replay, and automation?

Yes. Webhook.site has Custom Actions, HTTP retries, and replay. FastHook has Connection retry rules, request replay with modifications, saved fixtures, and app Workflows. Compare their execution and response behavior for your use case.

Does FastHook replace every Webhook.site feature?

No. Check specialized requirements such as disposable email capture, DNSHooks, content search, CSV export, synchronous responses from actions, and Enterprise SSO or custom domains before switching.
