## What it is
Airspeed Velocity (asv) is a Python benchmarking tool that tracks a project's performance over its git history. It generates an interactive static web frontend for comparing benchmark results across commits and releases.

## Use cases
- benchmark python package over git history
- detect performance regressions between commits
- generate web-based benchmark reports
- compare performance across releases
- set up continuous benchmarking for a library

## When to choose
- you maintain a Python library and want to track performance over time
- you need historical benchmark comparisons across commits
- you want shareable static benchmark reports

## When to avoid
- you need micro-benchmarks for a single code version only
- you benchmark non-Python code
- you need runtime production performance monitoring

## Facets
- artifact type: cli-tool
- maturity: active
- function: benchmarking, data-visualization, cli
- domain: developer-tools, performance, testing
- platform: python, cli, cross-platform
- tags: benchmarking-tool, performance-regression, web-reporting, git-history
