Score: 10/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 52, release rhythm 35, longevity 100
- inputs: {"age_days": 4159, "days_push": 288, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Catapult is a collection of performance tools from the Chromium project for gathering, displaying, and analyzing performance data, including Trace-viewer, Telemetry, the Performance Dashboard, Systrace, and Web Page Replay. The GitHub repository is deprecated; development continues at chromium.googlesource.com/catapult.

## Use cases
- analyze chrome performance traces
- run web page performance benchmarks
- visualize trace files from chrome or android
- monitor website performance over time
- record and replay web pages for testing
- profile android app performance

## When to choose
- you need to inspect or analyze Chrome/Android trace files
- you want to benchmark web pages with Telemetry
- you need Chromium's performance dashboard tooling

## When to avoid
- you want a general-purpose profiler unrelated to Chrome
- you expect active development on the GitHub mirror - it is deprecated
- you need a lightweight one-off benchmarking tool

## Facets
- artifact type: framework
- maturity: maintenance
- function: benchmarking, monitoring, tracing, data-visualization, testing
- domain: performance, developer-tools, web-development, monitoring
- platform: windows, python, cross-platform
- tags: chrome, chromium, trace-viewer, telemetry, performance-dashboard, systrace, profiling, linux, macos
