Thor is a Node.js CLI tool for benchmarking and load testing WebSocket servers. It generates large numbers of persistent WebSocket connections with configurable message traffic, filling a gap left by HTTP-only tools like ab and wrk.

Use cases

• load test a websocket server with thousands of concurrent connections
• benchmark ws and wss endpoints
• stress test reverse proxies and load balancers handling websocket traffic
• send configurable message sizes and counts per connection
• generate custom websocket message payloads for testing

When to choose

• you need to load test WebSocket servers rather than plain HTTP endpoints
• you want a simple CLI to open thousands of persistent ws/wss connections
• you need control over message count, size, protocol version, and concurrency

When to avoid

• you need to benchmark regular HTTP request/response performance
• you want a maintained tool with recent updates and active development
• you need a GUI or detailed metrics dashboards rather than CLI output
