Puffin is a lightweight instrumentation profiler for Rust, primarily aimed at game development, using scope macros that cost ~1ns when disabled. It supports in-game visualization via egui and remote profiling over TCP with puffin_http and puffin_viewer.

Use cases

• profile frame times in a Rust game
• find slow functions with flamegraphs
• profile a running application remotely over TCP
• add low-overhead profiling scopes to hot code paths
• visualize profiler data in-game with egui

When to choose

• you're building a game or real-time Rust application and need per-frame profiling
• you want near-zero overhead when profiling is disabled
• you want flamegraph visualization in-game or via a standalone viewer

When to avoid

• you need sampling-based profiling without code instrumentation
• you're profiling non-Rust code or need system-wide profiling
• you need production monitoring/telemetry rather than development profiling
