## What it is
Tinybench is a tiny (~10KB) JavaScript benchmarking library built on Web APIs with accurate timing via process.hrtime or performance.now. It provides statistically analyzed latency and throughput results, concurrency support, and works across multiple JS runtimes with zero dependencies.

## Use cases
- benchmark javascript functions
- compare performance of two implementations
- measure latency and throughput of code
- run microbenchmarks in node or browser
- get statistical analysis of benchmark results
- benchmark async tasks

## When to choose
- you need a lightweight, zero-dependency benchmarking library for JavaScript
- you want statistically rigorous results (std dev, margin of error, percentiles)
- you need benchmarks to run across multiple JS runtimes
- you want a simple API like bench.add() and bench.run()

## When to avoid
- you need full profiling with flame graphs or CPU sampling
- you benchmark non-JavaScript code
- you need a full benchmarking suite with CI dashboards and historical tracking

## Facets
- artifact type: library
- maturity: active
- function: benchmarking
- domain: developer-tools, performance, testing
- platform: cross-platform, cli
- tags: microbenchmarking, javascript, typescript, lightweight, web-apis, tinylibs, nodejs
