CatchHook vs. Webhook.site
The most popular webhook testing tool, rebuilt for modern developer workflows.
Webhook.site is a well-established tool for capturing and inspecting HTTP requests. It's been around since 2017 and serves 400,000 monthly users. CatchHook builds on the same core idea but adds developer-focused features: one-click replay, Endpoint Actions with retries, localhost tunneling, AI-powered debugging, and team collaboration.
Feature Comparison
| Feature | CatchHook | Webhook.site | Notes |
|---|---|---|---|
| Real-time inspection | |||
| Request search & filtering | |||
| Replay with request editing | Webhook.site requires Custom Actions to replay; CatchHook supports editing body, headers, and query params before replaying | ||
| Endpoint Actions (forward, tag, notify, ignore) | Both products support ordered conditional workflows. CatchHook integrates provider-aware conditions, request triage, and durable ActionRun/step traces directly into each captured event; Webhook.site provides Custom Actions, conditions, scripts, and action debugging. | ||
| Localhost tunneling (CLI) | |||
| AI payload summaries | |||
| AI handler code generation | |||
| Multi-channel alerts | Webhook.site only sends action failure emails | ||
| Team access controls | Webhook.site requires Enterprise ($69/mo) | ||
| Workspace isolation | Webhook.site has 'Groups' for organizing URLs (Enterprise only) but no isolated workspace environments | ||
| Custom response codes | |||
| CSV/JSON export | |||
| Request diff & compare | Side-by-side semantic diff of any two requests on the same endpoint | ||
| Health dashboard & diagnostics | Per-endpoint health status, recommended actions, inline delivery timeline | ||
| Request triage (tag, ignore, resolve) | Tag, ignore, or resolve requests to exclude noise from health metrics and alerts. No equivalent in Webhook.site. | ||
| Signature verification | |||
| No-code workflow builder | Both provide configurable workflow builders. CatchHook emphasizes provider-aware conditions, post-capture triage, and durable per-event execution traces; Webhook.site offers a broader Custom Actions integration catalog and scripting. | ||
| Custom domains | CatchHook allows one custom domain per workspace (multiple workspaces per account). Webhook.site requires Enterprise ($69/mo) and offers one domain per account with no workspace isolation. | ||
| Inbound email catching | CatchHook catches emails with full SPF/DKIM/DMARC verification, provider detection, and normalized JSON forwarding. Webhook.site captures emails without authentication analysis. | ||
| Per-request response capture | CatchHook records the exact status code, headers, and body returned to the webhook sender on every request | ||
| MCP server for AI editors | Debug webhooks from Claude Code, Cursor, Windsurf, or Codex CLI with 20 tools over Streamable HTTP |
Where CatchHook Stands Out
Replay & Forward in One Click
Replay captured webhooks to remote targets, or use the CLI tunnel for localhost. Paid Action Forward steps add bounded retries and durable execution traces.
Built-in Localhost Tunneling
No separate tool needed. The CatchHook CLI streams real webhook traffic to your local machine over WebSocket -- works with temporary endpoints too, no account required.
AI-Powered Debugging
Get instant plain-English summaries of complex payloads and generate handler code in Ruby, Python, and Node.js. Like having a senior dev review every webhook.
Alerts That Actually Route
Detect missing webhooks, error spikes, and traffic anomalies. Route alerts to Slack, PagerDuty, Discord, Teams, email, or any webhook URL.
