## What it is
Perfetto is an open-source suite of SDKs, daemons, and tools for production-grade system profiling, app tracing, and trace analysis on client and embedded systems. It is the default tracing system for Android and Chromium, offering a low-overhead C++ tracing SDK, OS-level probes, a browser-based trace viewer, and a SQL-based trace analysis engine.

## Use cases
- debug android app jank and slow startups
- profile cpu and memory usage on linux
- instrument c++ application with trace points
- visualize large multi-gb traces on a timeline
- query traces with sql to extract metrics
- trace linux kernel scheduling and syscalls
- analyze chrome json traces and perf data
- root-cause anrs and low memory kills on android

## When to choose
- you need low-overhead tracing on android or linux
- you want to correlate app-level events with system-wide profiling data
- you need to analyze very large traces with sql
- you want a browser-based offline trace viewer
- you are developing for android or chromium

## When to avoid
- you need distributed tracing across many machines like jaeger or zipkin
- you only need simple application logging rather than timeline tracing
- you need a managed cloud profiling service
- your target platform is not android, linux, or a browser

## Facets
- artifact type: framework
- maturity: stable
- function: tracing, monitoring, benchmarking, data-visualization, analytics
- domain: developer-tools, performance, operating-systems, mobile-development, web-development
- platform: windows, browser, cpp, python
- tags: trace-viewer, ftrace, system-profiling, sql-trace-analysis, android-tracing, chromium-tracing, heap-profiling, callstack-sampling, linux, macos, android
