HookRipple
Start free
BETAFree for everyone. No credit card.

Every request
has a ripple.

Send an API request, catch the webhook it sets off, and see the whole conversation side by side. One private workspace instead of five tabs.

  • Google or GitHub sign-in
  • Private by default
  • Nothing to install
Illustrative: a request (cyan) gets its response. When the API later sends a webhook (violet), HookRipple captures it and links it to the request by correlation ID. Not every request triggers a webhook.

FEATURES

Both directions of an integration.
One connected flow.

Send the request, catch what comes back, and understand how the two relate, all in one private workspace.

  1. 01 · SEND

    API client that stays out of your way

    REST and GraphQL over HTTP with ten auth schemes: Basic, Digest, Bearer, OAuth 2.0, API key, AWS Signature, Hawk, JWT and collection inheritance. Import from cURL, export code in six languages.

  2. 02 · CATCH

    A unique URL in one click

    Get a private webhook URL instantly. Every delivery is kept exactly as received: headers, query strings, form values and raw bytes. Copy any of them as cURL.

  3. 03 · LIVE

    Live, with catch-up

    Deliveries stream in the moment they land. Close the tab, come back later: missed events replay from durable storage.

  4. 04 · UNDERSTAND

    Cause meets callback

    Drop {{webhook_url}} into any request and HookRipple links the call you made to the webhook it triggered.

  5. 05 · VARIABLES

    Project, environment & request variables

    Layered variables with clear precedence, dynamic values like {{$guid}} and {{$timestamp}}, and secrets encrypted at rest.

  6. 06 · ORGANISE

    Collections with a runner

    Organise requests, set auth once per collection, and run the whole collection in order with a single click.

  7. 07 · CHECKS

    Checks, not scripts

    Assert on status codes, headers, JSON paths, body text and response time. Checks run on every response and in the collection runner; nothing you type is executed as code.

  8. 08 · REPLAY

    Replay, deliberately

    Edit a captured delivery, review exactly what will be sent, then confirm. One explicit attempt at a time, fully recorded.

HOW IT WORKS

From first request to replay
in about a minute.

  1. 01

    Create an endpoint

    Open the Webhook Inbox and create a private delivery URL on hooks.hookripple.com.

  2. 02

    Send your request

    Put {{webhook_url}} in the callback field of any request and hit Send.

  3. 03

    Watch it ripple

    The response lands on the left, the webhook streams in on the right, linked together.

  4. 04

    Replay with edits

    Tweak the payload, review the exact request, confirm. Every attempt is recorded.

SECURITY

Built like the payloads matter.
Because they do.

Webhooks carry customer records, tokens and order data. HookRipple treats every byte as confidential and every destination as untrusted.

Read the security overview

  • Encrypted at rest

    Payloads, request definitions and secrets are sealed with AES-256-GCM before they reach the database.

  • Isolated workspaces

    Membership checks in the app, plus PostgreSQL row-level security under restricted database roles.

  • Sandboxed outbound relay

    A separate executor with no access to secrets, pinned DNS, TLS verification and no redirects. Private networks are blocked at the kernel level too.

  • Short retention

    Captured payloads and history expire after 24 hours by default, and you can clear them anytime.

FAQ

Questions, answered.

Is HookRipple really free?

Yes. Everything is free while HookRipple is in beta: no credit card, no trial timer. If paid plans arrive later, the beta limits below stay free and you will get plenty of notice.

How do I receive a webhook?

Sign in, create an endpoint in the Webhook Inbox and paste its URL into the service that sends webhooks. Deliveries appear instantly, and you can inspect, download or replay each one.

Can it call localhost or my private network?

Not yet. The cloud relay only reaches public HTTP and HTTPS destinations on ports 80 and 443, which is what keeps the service safe for everyone. Browser-direct mode can reach anything your browser can, subject to CORS.

How long is data kept?

Captured payloads and request history are kept for 24 hours by default and then deleted automatically. Collections, environments and endpoints stay until you remove them.

Who can see my workspace?

Only you. Every workspace is isolated at the application layer and again by PostgreSQL row-level security. Sign in with Google or GitHub; we never see or store a password.

Will replaying a webhook trigger real actions?

It can, which is why replay is never automatic. You review the exact request first and confirm it explicitly. Original provider signatures may not validate on a replay.

Stop guessing what your
webhooks are doing.

Free during beta. Sign in with Google or GitHub and you're in.
