Subtrace
Zero code network tracer
Subtrace is a network monitoring tool that surfaces every HTTP request in production infrastructure without code changes, showing full payloads, latency, status codes, headers, and logs. It is installed with a single command and works across major languages, providing real-time visibility into production traffic for debugging.
Features include time travel replay of any production request locally with headers and body intact, copy as cURL, per-request latency breakdowns for understanding p99 behavior, and scoping the impact of third-party outages. It supports Node.js, Python, Go, Java, PHP, Rust, and Ruby, and runs on Docker, Kubernetes, AWS, Azure, and Google Cloud. Search is built on ClickHouse, and the tool is open source.
Subtrace is aimed at developers and teams debugging backend and production systems. It offers a free tier for hobbyists with limits on users and containers, paid Team and Scale editions with centralized billing and increasing retention, and an Enterprise edition with custom features, on-premise support, and uptime SLAs. A 14-day trial is available for commercial use, and annual subscriptions are offered on higher tiers.
