Quick Answer
For local integration testing, use the Stripe CLI (stripe listen). For inspecting raw payloads and sharing with teammates, use Requex.me — no installation, no account, instant URL.
Best Tools for Testing Stripe Webhooks
A practical comparison of Stripe CLI, Requex, ngrok, and webhook.site — so you pick the right tool for each stage of your Stripe integration.
Comparison at a Glance
| Tool | Cost | Setup | Signature Support | Real-Time | Sharable URL | Best For |
|---|---|---|---|---|---|---|
| Stripe CLI | Free | Install + login | Yes (auto) | Yes | No | Local handler testing |
| Requex | Free | Zero — instant URL | View raw header | Yes | Yes | Payload inspection & sharing |
| ngrok | Free tier / Paid | Install + auth | Pass-through | Yes | Temporary | Full end-to-end local test |
| webhook.site | Free / $9/mo | Zero | View raw header | Yes | Yes | Quick one-time inspection |
Stripe CLI — Best for Local Testing
The Stripe CLI is the official Stripe-provided tool and the gold standard for local webhook testing. Running stripe listen --forward-to localhost:3000/webhook tunnels live Stripe events directly to your local handler, complete with automatic signature generation.
This means your handler code actually runs. The CLI signs requests with a test webhook secret so your stripe.webhooks.constructEvent() call works identically to production.
The limitation: it requires installation, a Stripe login, and a running local server. It's not sharable — your teammates can't inspect the same payloads you're seeing.
Requex — Best for Payload Inspection
Requex gives you an instant HTTPS URL — no install, no account. Point Stripe at it, trigger an event, and see the raw payload immediately: every header including Stripe-Signature, the full JSON body, query params, and the HTTP method.
This is most useful at the start of an integration when you need to understand exactly what Stripe sends before writing any handler code. It's also useful for debugging production issues — paste the URL into your Stripe dashboard's webhook configuration, trigger the event, and share the inspection URL with teammates.
Requex also supports response simulation — return a 200, 400, or 500 to test Stripe's retry behaviour without deploying code.
ngrok — Best for End-to-End Local Testing
ngrok creates a public HTTPS tunnel to your localhost. Unlike the Stripe CLI, ngrok is provider-agnostic — it works for Stripe, GitHub, Shopify, or any service that sends HTTP requests.
ngrok does require installation and an account (for persistent URLs). The free tier assigns a new random subdomain each session, which means you need to update the webhook URL in Stripe's dashboard on every restart.
For Stripe specifically, the CLI is usually a better choice because it handles signature injection automatically. ngrok shines when you're testing multiple providers at once and need a single persistent tunnel.
When to Use Which
| Situation | Recommended Tool |
|---|---|
| Understand what Stripe sends before writing code | Requex |
| Test your local webhook handler end-to-end | Stripe CLI |
| Share a live payload URL with a teammate | Requex |
| Test Stripe + other providers simultaneously | ngrok |
| Simulate 500 errors to test Stripe retries | Requex |
| Quick payload peek, no install | Requex or webhook.site |
