Python APIs and bindings for Perfetto (perfetto.dev)
Decision gist · record as of 2026-08-14
Yes, if you need to programmatically analyze Perfetto traces or other compatible trace formats. The low install friction, active maintenance, permissive license, and zero known vulnerabilities make it a safe choice. The alpha status means the API may change, so pin the version in production. Not necessary if you only need the browser-based UI or one-off manual trace inspection.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with a single runtime dependency (protobuf).
- Active maintenance with recent releases; last commit 2026-08-14 and version 0.57.2 released 2026-07-07.
- Alpha status indicates the API may still evolve.

What it is and what it does
Perfetto is a Python interface to Perfetto's trace processor, enabling programmatic analysis of system and application performance traces. It lets you load trace files and query them using SQL, making it possible to automate trace analysis, extract custom metrics, and integrate trace inspection into Python workflows. The package is built on top of Perfetto's production-grade tracing infrastructure, which is the default system for Android and Chromium.
The package depends only on protobuf and installs as a pure Python wheel, making it lightweight to add to existing projects. It's designed for developers, performance engineers, and SREs who need to analyze traces captured by Perfetto daemons or other compatible tools—such as Linux perf, Chrome JSON traces, or macOS Instruments—without manually parsing binary formats.
Use it for
- Automate analysis of Android app performance traces to detect slow startups, dropped frames, or memory issues
- Query Linux kernel traces to analyze scheduling behavior, syscalls, and CPU performance bottlenecks
- Extract custom metrics from Chromium browser traces for performance regression detection
- Batch-process multiple trace files to generate performance reports and SRE dashboards
- Integrate trace analysis into CI/CD pipelines to flag performance regressions automatically
