Subtrace

Subtrace is a debugging tool tailored for Docker containers, offering a Wireshark-like experience focused on HTTP requests within backend servers. It gives developers detailed visibility into all incoming and outgoing requests, providing information often missing in tools like Sentry and OpenTelemetry. Subtrace captures and displays every request passing through a backend server, providing details such as the full payload, headers, status code, and latency. It uses BPF technology without requiring root privileges or code changes, and offers a self-hosted option with Kubernetes support, metadata tagging, and powerful filtering.
