Webhook testing is a critical part of modern API development. Whether you're integrating with Stripe, GitHub, Shopify, or building your own event system, you need a reliable way to inspect, debug, and test incoming webhooks.

Here's a comparison of the most popular webhook testing tools in 2026.

1. HookSense

Best for: AI agents that need to await async callbacks over MCP, plus the local forwarding and replay tooling around them.

  • Agent-native callbacks: create_callback_endpoint + wait_for_callback over MCP — no polling
  • Works in Claude Desktop, Cursor, Claude Code, any MCP client: npx @hooksense/mcp
  • Callbacks signature-verified and decrypted before the agent acts (Stripe, GitHub, Shopify, custom HMAC)
  • Request replay with one click
  • CLI for local forwarding: npx hooksense listen -p 3000
  • 14-day retention + permanent URLs on free plan
  • From $29/mo for advanced features (paid plans early-access)

2. Webhook.site

Best for: Quick, one-off webhook inspections.

  • Instant URL generation — no signup required
  • Clean UI for viewing requests
  • 24-hour data retention on free plan
  • No real-time updates (requires page refresh)
  • No CLI or local forwarding
  • No request replay
  • Premium from $12/mo

3. WebhookDebugger.com

Best for: Simple webhook inspection with a minimal UI.

  • Free to use
  • Basic request inspection
  • Limited features compared to alternatives
  • No CLI, no replay, no signature verification

4. Hookdeck

Best for: Production webhook infrastructure and routing.

  • Webhook gateway with routing, filtering, and transformations
  • Automatic retries and delivery guarantees
  • More infrastructure-focused, less developer-tool-focused
  • Complex setup for simple testing use cases
  • Higher pricing for individual developers

Our Recommendation

If your webhooks feed an AI agent, HookSense is the one purpose-built for it — the agent awaits callbacks over MCP with wait_for_callback instead of polling, and every callback is signature-verified and decrypted first. You also get replay, signature verification, and CLI forwarding on a generous free tier.

If you need production webhook infrastructure with routing and retries between your own services, consider Hookdeck. For quick one-off inspections without signing up, Webhook.site works fine.
