TCPCopy is a TCP stream replay tool that captures live production traffic and replicates it against a test server. It enables realistic stress, performance, stability, and regression testing by generating workloads that mirror production request diversity and network latency.

Use cases

• replay production HTTP traffic to a staging server
• stress test nginx or mysql with real-world traffic
• validate stability of a new system before launch
• run regression testing with live traffic patterns
• compare performance across server versions or configurations
• pre-warm caches with replicated production requests

When to choose

• you need realistic production-like workloads instead of synthetic load generators
• you want to replay live TCP traffic (HTTP, MySQL, Redis, etc.) with minimal production impact
• you need distributed stress testing across multiple servers

When to avoid

• you only need simple synthetic load testing without real traffic
• your environment cannot run raw-socket packet capture or route response packets to an assistant server
• you need a cross-platform GUI tool rather than a Linux C command-line utility
