local webhook testing tool

If you want a local webhook testing tool, here are the most common options:

Quickest options

• ngrok — exposes your local server to the internet so services can hit your webhook locally.
• webhook.site — generates a temporary public URL and shows incoming requests.
• RequestBin / Pipedream / Beeceptor — similar “inspect incoming webhooks” tools.

If you want fully local-only

• Webhook Relay
• LocalStack (for AWS-style integrations)
• Mockoon — create a local mock API and inspect requests
• Postman Mock Server — for testing request/response flows

Simple self-hosted option

Run a tiny local server and inspect payloads:

• Node.js/Express
• Python/Flask/FastAPI
• Go / Rust / PHP, etc.

Example with Node.js:

import express from "express";

const app = express();
app.use(express.json());

app.post("/webhook", (req, res) => {
  console.log("Headers:", req.headers);
  console.log("Body:", req.body);
  res.sendStatus(200);
});

app.listen(3000, () => console.log("Listening on http://localhost:3000/webhook"));

Then point your webhook provider to:

• http://localhost:3000/webhook if it can reach your machine
• or use ngrok to get a public URL

If you want, I can recommend the best tool for your exact use case:

• testing Stripe/PayPal/GitHub webhooks
• local development only
• production debugging
• no-code setup
