hotpath-rs is an easy-to-configure Rust performance profiler that pinpoints where code spends time, burns CPU, and allocates memory. It instruments functions, channels, futures, streams, SQL queries, HTTP calls, and I/O, offering one-off reports and a live TUI dashboard, plus MCP support for AI coding agents.

Use cases

• find cpu bottlenecks in rust code
• profile memory allocations and leaks in rust
• measure sql query performance with sqlx or diesel
• monitor throughput and latency of io streams
• profile async channels and futures
• track http client and axum route latency
• let an ai agent set up profiling in a repo

When to choose

• you need a low-setup profiler for Rust covering CPU, memory, SQL, HTTP, I/O and async
• you want to distinguish I/O-bound from CPU-bound slowness
• you want live TUI monitoring or agent-friendly profiling setup

When to avoid

• you need profiling for languages other than Rust
• you need a full-fidelity sampling profiler with flamegraphs rather than instrumentation-based metrics
• your project cannot tolerate instrumentation overhead in hot paths
