A standalone GUI for visualizing and analyzing Linux perf data, featuring flame graphs, timeline filtering, and off-CPU profiling.
What is hotspot?
Hotspot is a standalone GUI application for performance analysis on Linux, specifically designed to visualize and explore data recorded with the Linux `perf` tool. It transforms raw perf output into interactive flame graphs, timeline views, and detailed call stacks, helping developers identify bottlenecks and optimize their applications. The tool also supports advanced features like off-CPU profiling and embedded system analysis.
Linux developers, performance engineers, and system analysts who need to profile and optimize applications using Linux perf but prefer a graphical interface over command-line tools.
Hotspot provides an intuitive and feature-rich GUI that makes Linux perf data accessible without sacrificing depth, offering unique capabilities like integrated off-CPU profiling, timeline filtering, and support for embedded systems—all as a free, open-source alternative to proprietary profiling tools.
