What is Subtrace?

Subtrace is a debugging tool specializing in monitoring Docker containers by bringing a Wireshark-like interface for HTTP request analysis in backend servers. It offers developers an in-depth view of all incoming and outgoing requests, detailing payloads, headers, status codes, and latency—information typically lacking in tools like Sentry and OpenTelemetry. With its user-friendly, Chrome DevTools-style interface, Subtrace simplifies production debugging, API troubleshooting, security auditing, and performance monitoring. Featuring automatic tracing, powerful request filtering, and a self-hosted option, Subtrace facilitates seamless integration with Linux, Docker, and Kubernetes environments while maintaining user data privacy locally.
