GoReplay is an open‑source command‑line tool that captures live HTTP traffic from a network interface and replays it against a test environment. It enables reality‑driven testing, shadow deployments, and load testing without modifying production services.
Use cases
- capture live HTTP requests and replay them to a staging server
- shadow test a new release by sending a copy of production traffic to it
- load test an API using a recorded workload at controlled speed
- debug production bugs by replaying captured requests and comparing responses
- record HTTP traffic to a file and later replay it for performance analysis
When to choose
- you want to test with real production traffic without instrumenting the application
- you need a lightweight, no‑code‑change solution for shadow or load testing
- you prefer a CLI tool that works on Linux, macOS, and Windows
- you want to capture traffic after TLS termination and replay as plain HTTP
When to avoid
- your service uses non‑HTTP protocols or binary protocols not supported by the open‑source version
- you require deep request/response manipulation beyond simple filtering
- you need a fully managed SaaS solution with built‑in analytics
- you cannot obtain the required root/CAP_NET_RAW permissions on the host
