## What it is
BuckyClient is a browser/Node library that collects client-side performance data (page load times, AJAX request durations, function timings) and sends it to a Bucky server for forwarding into statsd, Graphite, or OpenTSDB. It measures real user page loads rather than synthetic in-vitro benchmarks.

## Use cases
- measure real user page load times in the browser
- track how long AJAX requests take from actual clients
- time how long specific functions take to run in production
- send client-side performance metrics into statsd or OpenTSDB
- subsample performance data collection from high-traffic sites
- monitor frontend performance across browsers with performance.timing

## When to choose
- you already use statsd, Graphite, or OpenTSDB and want real-user browser performance data
- you want a lightweight script-tag drop-in for page and request timing
- you need to measure performance on actual user page loads rather than synthetic tests

## When to avoid
- you need a modern, actively maintained RUM solution (last release was 2016)
- you use modern observability platforms like Datadog, Sentry, or OpenTelemetry instead of statsd
- you need server-side or full-stack tracing rather than browser-only metrics

## Facets
