ngrok vs localtunnel vs webhook.site 2026

TL;DR

ngrok is the industry standard for local tunneling — HTTPS out of the box, persistent subdomains, request inspection UI. localtunnel is the open-source zero-config alternative — no account required, free forever, but ephemeral URLs and no inspection. webhook.site is purpose-built for webhook debugging — you don't run it locally at all; it gives you a hosted URL that logs every request in real-time. For most developers: start with webhook.site for quick debugging, add ngrok when you need a stable URL for CI or testing, consider localtunnel for lightweight personal use.

Key Takeaways

• ngrok is the most mature and reliable — fixed URLs, request replay, OAuth proxy, dashboard
• ngrok Free now limits to 1 static domain and requires an account (email verification)
• localtunnel is zero-friction for one-off use — npx localtunnel --port 3000 with no account
• webhook.site is the fastest way to inspect webhook payloads — no local server needed
• smee.io (bonus) is GitHub's own webhook proxy — purpose-built for GitHub webhook testing
• Cloudflare Tunnel is the production-grade alternative for persistent internal services
• All three tools use HTTPS by default — your local service doesn't need SSL configured

The Webhook Development Problem

Building against webhooks is uniquely annoying compared to REST API consumption. With REST APIs, you make outbound calls — your app initiates contact. With webhooks, the service calls you — which means your local development server needs to be publicly reachable.

Three scenarios where this matters:

1. Stripe/Paddle webhooks — payment events (checkout.session.completed, payment_intent.succeeded) must hit a real HTTPS URL
2. GitHub Actions webhooks — push, pull_request, deployment_status events during local testing
3. Slack/Discord bots — slash commands require a live HTTPS endpoint to respond within 3 seconds

The naive solution is deploying to staging every time you want to test a webhook event. A tunnel tool makes local development work.

ngrok — The Industry Standard

Best for: Developers who need reliable tunnels, fixed subdomains, and request inspection

ngrok has been the default tunnel tool since 2015. In 2026, it's expanded into a developer networking platform — beyond tunneling, it handles OAuth, request inspection, rate limiting, and even OIDC authentication proxying.

Getting started:

# Install
brew install ngrok/ngrok/ngrok

# Authenticate (free account required)
ngrok config add-authtoken YOUR_TOKEN

# Start a tunnel
ngrok http 3000

# Output:
# Forwarding  https://abc123.ngrok-free.app -> http://localhost:3000
# Web Interface: http://127.0.0.1:4040

The ngrok inspection UI at localhost:4040 is one of the most underrated developer tools available. Every request is logged with:

• Full headers and body
• Response status and latency
• One-click Replay button — resend any captured request without triggering the original event

# Replay a webhook from the CLI
ngrok api requests --tunnel-name default

ngrok's developer features:

# Static subdomain (free tier: 1 domain)
ngrok http --domain=myapp.ngrok-free.app 3000

# OAuth proxy — add Google login to any local service
ngrok http --oauth=google --oauth-allow-domain=mycompany.com 3000

# Basic auth on your tunnel
ngrok http --basic-auth="admin:secret123" 3000

# Custom response headers
ngrok http --response-header-add="X-Frame-Options:DENY" 3000

# Traffic policy (rate limiting)
ngrok http --traffic-policy-file=policy.yaml 3000

ngrok pricing:

Plan	Price	Features
Free	$0	1 static domain, 1 tunnel, basic inspection
Personal	$8/month	3 domains, 3 tunnels, OAuth proxy
Pro	$20/month	10 domains, custom domains, TCP tunnels
Business	$30/month/agent	SSO, team management, audit logs

ngrok's config file for multi-service development:

# ~/.config/ngrok/ngrok.yml
version: "3"
agent:
  authtoken: your_token_here

tunnels:
  api:
    proto: http
    addr: 3000
    domain: myapi.ngrok-free.app
  frontend:
    proto: http
    addr: 5173
  webhook-receiver:
    proto: http
    addr: 8080

# Start all: ngrok start --all

Where ngrok falls short: The free tier has become more restrictive over time. No custom domains on free. Tunnels drop when your laptop sleeps (use ngrok start --all with restart-on-failure). The ngrok binary phones home — some security-sensitive environments block it.

localtunnel — Zero-Friction Open Source

Best for: Quick one-off exposure of a local port without creating an account

localtunnel is the npm package that gives you a public HTTPS URL in one command with no account, no API key, and no CLI installation required.

# No installation needed
npx localtunnel --port 3000

# Output:
# your url is: https://silly-butterfly-42.loca.lt

localtunnel's advantages:

• No account — anonymous, no email, no token
• Always free — fully open source, community-funded servers
• Subdomain request — ask for a specific subdomain (not guaranteed)

# Request a specific subdomain
npx localtunnel --port 3000 --subdomain mydev-project
# https://mydev-project.loca.lt (if available)

The catch: localtunnel's public URLs often display a "tunnel password" page for first visitors — a spam protection measure. You can bypass this for automated tools:

# Bypass tunnel warning for automated HTTP clients
curl -H "bypass-tunnel-reminder: anything" https://your-url.loca.lt/api/health

Using localtunnel in scripts:

// In development scripts or tests
import localtunnel from 'localtunnel';

const tunnel = await localtunnel({ port: 3000 });
console.log(`Tunnel URL: ${tunnel.url}`);

// Register webhook with the tunnel URL
await registerWebhook(tunnel.url + '/webhooks/stripe');

// Clean up
tunnel.on('close', () => console.log('Tunnel closed'));
process.on('SIGINT', () => tunnel.close());

localtunnel reliability: The shared server infrastructure is community-maintained, not backed by a company. URLs drop more frequently than ngrok. For critical webhook testing during important demos, ngrok is more reliable.

Where localtunnel wins: Absolute zero friction. No account, no config, paste one command. Perfect for sharing a local prototype with a teammate ("check this out real quick") or quick webhook testing.

webhook.site — The Webhook Debugger

Best for: Inspecting webhook payloads without setting up any local server

webhook.site is a different tool than ngrok or localtunnel. Instead of tunneling to your local server, it provides a hosted URL that captures and displays every request — no server required.

The workflow:

1. Visit webhook.site
2. Get an instant unique URL: https://webhook.site/abc123-def456-...
3. Paste that URL as your webhook endpoint in Stripe, GitHub, Slack, or wherever
4. Trigger the webhook event
5. See the full request in real-time in your browser

# Example: Testing a Stripe webhook
# 1. Go to webhook.site → copy your unique URL
# 2. In Stripe Dashboard → Developers → Webhooks → Add endpoint
#    URL: https://webhook.site/abc123-def456-789012
#    Events: checkout.session.completed
# 3. Create a test payment
# 4. webhook.site shows you the exact payload Stripe sends

What webhook.site shows you:

• Full request headers (Content-Type, Stripe-Signature, etc.)
• Raw body (JSON, form-encoded, XML)
• Query parameters
• Method and path
• Timestamp and latency

webhook.site features:

• Custom responses — set status code, headers, and body to simulate your server's response
• Delay responses — test timeout handling by making webhook.site wait before responding
• Extract variables — parse the incoming payload and use values in the response
• Repeat to URL — forward captured webhooks to your local server (requires webhook.site Pro)
• Email — webhook.site also gives you a temporary email address for testing

webhook.site pricing:

• Free: Unlimited requests, requests visible for 7 days, 1 URL at a time
• Pro: $9/month — multiple URLs, repeat to URL, longer history, team sharing

The "forward to localhost" workflow:

webhook.site Pro's "Repeat to URL" feature turns it into an ngrok alternative for some cases:

1. Configure webhook endpoint as https://webhook.site/your-url
2. webhook.site receives the event from Stripe/GitHub/etc.
3. webhook.site forwards to http://localhost:3000/webhooks/stripe
4. Your local server responds

This is slower than a direct tunnel (double hop) but works well when you want inspection + forwarding.

smee.io — GitHub's Webhook Proxy

Best for: GitHub webhook development (Actions, Apps, OAuth integrations)

smee.io is GitHub's official webhook proxy tool — built specifically for developing GitHub Apps and Actions locally.

# Install the smee client
npm install -g smee-client

# Get a channel URL from smee.io (one click)
# Then:
smee --url https://smee.io/abc123 --target http://localhost:3000/webhooks/github

# Or use the Node.js client in tests:
const SmeeClient = require('smee-client')
const smee = new SmeeClient({
  source: 'https://smee.io/abc123',
  target: 'http://localhost:3000/webhooks/github',
  logger: console
})
const events = smee.start()

smee.io is free, no account needed, and works reliably for GitHub-specific use cases. It's essentially localtunnel but purpose-built for GitHub's webhook format.

Common Patterns

Stripe webhook development:

# Option A: ngrok (most reliable, can replay)
ngrok http 3000
# Register https://abc.ngrok-free.app/webhooks/stripe in Stripe Dashboard

# Option B: Stripe CLI (best for Stripe-specific)
stripe listen --forward-to localhost:3000/webhooks/stripe
# Built-in replay, no ngrok needed for Stripe events

Verifying webhook signatures locally:

// The webhook URL doesn't matter for signature verification —
// what matters is the raw body and the secret
import Stripe from 'stripe';
const stripe = new Stripe(process.env.STRIPE_SECRET_KEY);

app.post('/webhooks/stripe', express.raw({type: 'application/json'}), (req, res) => {
  const sig = req.headers['stripe-signature'];

  let event;
  try {
    event = stripe.webhooks.constructEvent(
      req.body,                          // raw buffer, not parsed
      sig,
      process.env.STRIPE_WEBHOOK_SECRET  // from Stripe Dashboard
    );
  } catch (err) {
    return res.status(400).send(`Webhook Error: ${err.message}`);
  }

  res.json({ received: true });
});
