AI-Generated Review

What is lazypprof?

lazypprof is a keyboard-driven TUI built in Go for exploring pprof profiles from your terminal. It loads CPU, heap, goroutine, mutex, or block profiles from files, diffs two for regressions, or polls live services over HTTP—no browser needed, and it works anywhere, including over SSH. Ditch the clunky go tool pprof -http workflow for instant top lists, call trees, flame graphs, and goroutine breakdowns.

Why is it gaining traction?

It's faster than firing up a browser for pprof -http, with vim-like keys for zooming flame graphs, expanding trees, and filtering by regex. Live mode auto-polls localhost:6060 or custom endpoints at tunable intervals, history navigation, and diff coloring (red for regressions, green for wins) make profiling feel snappy. Terminal flame graphs and goroutine state grouping stand out—no JavaScript bloat, just pure keyboard flow.

Who should use this?

Go backend devs debugging production services remotely via SSH, ops engineers hunting heap leaks or goroutine blocks without GUI tools, and CI/CD folks diffing profiles across builds. Ideal for anyone tired of browser tabs during perf spikes on low-resource servers.

Verdict

Grab it for quick terminal profiling—installs easily via go install or brew, solid docs and demos. With only 10 stars and 1.0% credibility, it's early but battle-tested with tests and releases; worth a spin if you live in pprof.
