Trayce: Lightweight Network Monitor for Local Docker Containers

Lightweight local Docker container network monitoring tool for developers

From Hacker News Original Article Hacker News Discussion

Trayce is a tool designed to monitor network traffic inside local Docker containers, providing a fast, lightweight HTTP client interface without relying on a browser or Electron. It captures requests using an agent with eBPF probes and supports various protocols like HTTP, HTTPS, GRPC, MySQL, and Postgres.

Why it matters: Developers and testers get instant visibility into container network traffic to debug and test locally without heavy tools.

The big picture: Trayce focuses on local, offline container monitoring rather than production environments, differentiating it from broader monitoring solutions.

The stakes: Licensing confusion exists as the tool is GPL 3 on GitHub, but a purchase is required for continued use, causing community questions.

Commenters say: Users appreciate the Docker-specific integration but note a crowded market and seek clarity on licensing and production use cases.
