What is Nusku and how do I try it?

Nusku's an open-source eBPF profiler for Linux CPU debugging. Clone from GitHub, build with Cargo, run `nusku --pid ` on any process.

How does Nusku compare to perf or flamegraphs?

Perf dumps data; Nusku shows live, symbolized stacks in terminal. Flamegraphs are static; this updates real-time, zero setup.

Is Nusku production-ready?

Low-overhead eBPF yes, but polish incoming (TUI, memory). Test on non-crit first; roadmap targets prod simplicity.
