webhook.site is free but HTTP-only — no WebSocket, no SSE, no AI. ngrok requires CLI installation and a local server. Postman is general-purpose, not event-focused. SynapHook is 36 tools across 3 modules: capture webhooks in real time, test WebSocket and SSE connections from your browser, and AI-generate production-ready handler code from captured payloads. Privacy-first: payloads auto-expire, never permanently stored. No account. No CLI. No server to run.
A complete event integration testing environment. Capture real webhooks, inspect payloads and headers, mock provider responses, and replay scenarios with automated diffing. Built for backend developers, integration engineers, and QA teams who need to verify webhook handling before production.

Module walkthrough
17 tools. Generate webhook endpoints with one click. Inspect incoming HTTP requests — headers, payload, signature, source IP — in real time. Simulate Stripe, GitHub, Twilio signatures. Test retry logic, error handling, and edge cases.
Module walkthrough
6 tools. Connect to WebSocket and SSE endpoints directly from your browser — no proxy, no relay. Inspect messages in real time. Test auto-reconnection behavior. Simulate connection drops and message floods.
Module walkthrough
13 tools. AI generates production-ready handler code (Express, Fastify, Flask, Go, PHP) from captured webhook payloads. Debugs failing handlers. Diffs schema changes. Generates integration tests. Audits security. Simulates event sequences.
SynapHook runs in your browser. Webhook endpoints are hosted on Lambda + DynamoDB — no deployment required. WebSocket and SSE connections are browser-native.
SynapHook is not just a request bin. It is a complete event integration testing platform — HTTP webhooks, WebSocket, SSE, and AI-powered handler code generation in one tabbed interface.
One click → working HTTP endpoint. No forms, no config, no server to run. The endpoint is the product. WebSocket and SSE connections open directly from your browser — no proxy, no relay.
Every header, query param, body, timestamp, and source IP — visible in real time. No filtered view. The unhappy path (429s, 500s, timeouts) is as visible as the happy path.
Captured payloads generate production-ready handlers in Express, Fastify, Flask, Go, and PHP — not pseudocode. AI debugs failures, diffs schema changes, and audits security.
HTTP webhooks + WebSocket + SSE in one platform. No switching tools when the event transport changes. Tabbed interface keeps all three surfaces visible.
Payloads auto-expire via DynamoDB TTL — displayed and discarded, never permanently stored. Realtime connections are browser-native — data never touches our servers.
Every CAMTECH AI product solves a real problem — for us, for our clients, or for the internet.
Testing webhooks is painful. You deploy your app, configure Stripe to send events to production, trigger a test payment, and hope the webhook arrives. If it fails, you check logs, fix the handler, redeploy, and try again. Every iteration costs minutes of deploy-and-wait. Webhook testing tools exist (webhook.site, ngrok) but none provide scenario recording with diffing, signature verification testing, or retry logic simulation.
Integration engineers spend 30–40% of their development time on webhook handler verification — most of it waiting for deployments.
CAMTECH AI built SynapHook to eliminate the deploy-and-wait cycle for webhook testing. Capture real events once — replay them instantly with identical timing and diff runs to find exactly what changed. Mock provider failures: 429 rate limits, 500 errors, connection drops. Verify HMAC-SHA256, JWT, and custom signatures. Simulate delivery failures with exponential backoff and duplicate events to confirm idempotency. All from the browser — zero deployment, zero CLI, zero server to run. AI generates production-ready handler code in Express, Fastify, Flask, Go, and PHP from captured payloads. Built on the same stack as every CAMTECH AI product: Next.js static export, AWS Lambda + DynamoDB for hosted endpoints with auto-expiring payloads.
SynapHook is built and maintained by the same team that delivers AI automation and managed infrastructure for PYMEs across LatAm and the US.
