Webhooks are everywhere in 2026 — Stripe, GitHub, Slack, Shopify, Twilio, and hundreds of other services push events to your endpoints. But testing them without a running server is annoying. That's where hosted webhook inspection tools come in.
This post compares the main options in 2026, so you can pick the right tool for your workflow.
What you actually need from a webhook testing tool
Before comparing, let's nail down the requirements:
- Unique inspection URL — a real HTTPS endpoint that accepts any HTTP method
- Real-time request viewing — see headers, body, query params instantly
- Payload replay — resend captured payloads to your local server without re-triggering the original event
- Persistence — saved history for debugging after the fact
- Transform rules — filter or mask sensitive data before storing (useful for Stripe payloads with card data)
The main free options
webhook.site
The OG. Generates a unique URL instantly, no account needed. Clean UI, shows headers, body, and query params in real-time.
Free plan limits: 50 requests per URL, URLs expire. Paid plans start at $7.50/month for unlimited requests and workflows.
Best for: quick one-off tests where you just need to confirm a webhook fired.
Not great for: long-running debug sessions, replaying payloads, or teams sharing endpoints.
RequestBin (via Pipedream)
RequestBin was acquired by Pipedream and relaunched as part of their platform. It still gives you a free inspection URL, but it's now deeply integrated with Pipedream's workflow automation.
Free plan limits: limited event history, account required.
Best for: developers already using Pipedream who want to chain webhooks into automations.
Not great for: pure webhook inspection — the UI has become automation-first.
ngrok (inspect mode)
ngrok is primarily a tunnel to localhost, but its web inspector at localhost:4040 is excellent for debugging webhooks hitting your local dev environment.
Free plan limits: ngrok URLs change on restart (unless paid), connection limits apply.
Best for: developers who need to test against a locally running service.
Not great for: sharing URLs with external services or when you don't want to keep a local process running.
HookTest
HookTest is a newer option that addresses some of the gaps in the tools above.
Free plan: 3 endpoints, 24-hour TTL, real-time inspection — no account needed.
What's different:
Payload replay — resend any captured webhook to a different target URL. Useful when you want to replay a Stripe event to your local
ngrokendpoint without re-triggering the actual Stripe flow.Transform rules — mask, rename, or filter fields in payloads before they're stored. Handy when Stripe payloads include partial card data and you want to avoid logging it.
Works without ngrok — endpoints are real HTTPS URLs with no local process required.
Pro plan ($9/month): 10 persistent endpoints, transform rules, extended history.
Quick comparison table
| Feature | webhook.site | RequestBin | ngrok inspect | HookTest |
|---|---|---|---|---|
| No account needed | ✓ | ✗ | ✗ | ✓ |
| Real-time inspect | ✓ | ✓ | ✓ | ✓ |
| Payload replay | ✗ | ✗ | ✓ (local only) | ✓ |
| Transform/mask fields | ✗ (paid) | ✗ | ✗ | ✓ |
| Persistent history | ✗ (free) | limited | ✗ | ✗ (free) / ✓ (pro) |
| Custom domain | ✗ (free) | ✗ | ✓ (paid) | upcoming |
| Free request limit | 50/URL | limited | unlimited (local) | 100/endpoint |
Choosing the right tool
- Quick one-time test → webhook.site (fastest, no friction)
- Local development + debugging → ngrok
- Workflow automation → RequestBin via Pipedream
- Replay, masking, team use → HookTest
The real workflow killer is having to re-trigger events from the source to debug a payload parsing issue. With replay, you capture the event once and resend it as many times as you need — even to a different URL (like your localhost).
