py-spy is a sampling profiler for Python programs. It lets you visualize what your Python program is spending time on without restarting the program or modifying the code in any way. py-spy is extremely low overhead: it is written in Rust for speed and doesn't run in the same process as the profiled Python program. This means py-spy is safe to use against production Python code. py-spy works from the command line and takes either the PID of the program you want to sample from or the command line of the python program you want to run. py-spy has three subcommands record, top and dump. py-spy supports recording profiles to a file using the record command. ...

Buildprof is a Linux build profiler that records every process launched during a build and turns the trace into an interactive browser timeline. It follows the full process tree across build systems, compilers, linkers, code generators, and arbitrary scripts. Users can inspect command lines, working directories, exit statuses, timing, and file accesses to find slow steps or gaps in parallelism.

Twiggy is a specialized code size profiler designed for analyzing WebAssembly (Wasm) binaries, helping developers understand why their compiled output is large and how different functions contribute to that size. It works by inspecting a binary’s call graph and providing detailed breakdowns of which functions are included and how they are interconnected, allowing developers to trace dependencies and identify unnecessary code paths.
