Inspectr is a lightweight and high-performance API Proxy designed for reviewing, analyzing, and debugging API requests, MCP tool calls, and webhook events. It also offers a built-in tunnel option for securely sharing local services publicly, streamlining integration testing, monitoring, and troubleshooting payload issues.

inspectr is currently grouped under Observability, which makes it easier to evaluate through workflow fit instead of isolated features alone. Based on the available data, it leans most heavily toward Inspect API Requests: View headers, query parameters, request bodies, and response details. and Debugging During Development: Real-time monitoring and inspection of requests to identify malformed data or errors.. The listed license is GPL-3.0, which is useful when adoption constraints matter. It also shows measurable community traction with 13 GitHub stars.

How it compares

≈inspectr sits in the Observability category, so it makes more sense to evaluate it alongside tools like worldmonitor instead of in isolation.

≈If your main need is closer to "Debugging During Development: Real-time monitoring and inspection of requests to identify malformed data or errors.", that use case is a better lens for comparison than broad feature checklists alone.

≈inspectr uses a GPL-3.0 license, and community traction are both easier to judge in category context.
