Flameshow is a terminal-based Flamegraph viewer written in Python that renders and lets you interactively explore profiling data. It supports Golang pprof, Brendan Gregg's collapsed-stack flamegraphs, and Python Austin profiles, with keyboard and mouse navigation.
Use cases
- view a golang pprof goroutine dump in the terminal
- interactively zoom into flamegraph spans from the command line
- analyze CPU profiling output without a browser
- inspect python austin profiler output in a TUI
- render collapsed-stack flamegraph files in a terminal
When to choose
- you profile servers over SSH and want flamegraphs without a GUI or browser
- you work with golang pprof dumps and want quick terminal inspection
- you prefer keyboard-driven TUI tools for performance analysis
When to avoid
- you need rich web-based flamegraph features like diffing or search across large profiles
- your profiler emits an unsupported format and you cannot convert it
- you need a GUI with persistent sharing or embedding of flamegraphs
