ngrok tunnels live traffic to your localhost, but it requires a running agent, doesn't persist requests, and has rate limits. WebhookVault captures and stores every webhook for replay anytime.
ngrok is a popular tunneling tool that exposes your local development server to the internet via a secure tunnel. Developers use it to receive webhooks directly on localhost by creating a public URL that forwards traffic to a local port. ngrok is widely used for webhook development, but it's a general-purpose tunnel, not a dedicated webhook tool.
A detailed, side-by-side look at how WebhookVault and ngrok compare across the features that matter most for webhook debugging.
| Feature | WebhookVault | ngrok |
|---|---|---|
| Architecture | Cloud capture + on-demand replay | Local tunnel agent |
| Persistent Storage | All requests stored with full history | No persistence — lost on tunnel restart |
| Offline Capture | Captures while you're offline | Must be running to receive |
| Replay | Replay any request to any URL | No replay capability |
| Stable URLs | Permanent endpoint URLs | URL changes on free tier restart |
| Local Software | None required | ngrok agent must be installed and running |
| REST API | Full API for request retrieval | Local API for active tunnel only |
| CI/CD Integration | API-driven, works in any pipeline | Requires agent in CI environment |
| Rate Limits (Free) | 100 requests/endpoint | 20 connections/minute |
| Pricing | Free tier + $9/mo Pro | Free tier + $8/mo Personal |

We believe in honest comparisons. Here's when each tool is the better fit.
ngrok is the better choice when you need real-time, live traffic tunneled to your local server for interactive debugging, or when you need a tunnel for non-webhook use cases like demos and API testing.
WebhookVault is the better choice when you need persistent webhook capture, the ability to replay requests on demand, offline capture, stable URLs, and API-driven access for CI/CD testing workflows.
