Shareable benchmark pages
Save benchmarks as stable URLs with revisions instead of treating results as disposable scratchpad state.
JavaScript and TypeScript
Write modern typed snippets, keep source readable, and run prepared JavaScript where engines require it.
Beyond browser-only results
Use Deep Analysis and the optional worker path for QuickJS, V8, Node, Deno, and Bun context.

When jsPerf is a good fit

Use jsPerf when a benchmark should be easy to revisit, share, and explain.

You want stable URLs for team discussions, issues, pull requests, or docs.

You need benchmark revisions as the code or methodology changes.

You want runtime context beyond one browser execution environment.

How to start

A good migration keeps the benchmark focused.

Copy the setup data into preparation or setup code.

Add each competing implementation as a separate test case.

Save the benchmark and link teammates to the canonical jsPerf URL.

Benchmark clarity

Frequently asked questions

Short answers for searchers, with enough context to help them create a better benchmark.

Is jsPerf an alternative to JSBench?

Yes. jsPerf is an online JavaScript benchmark tool for creating, running, saving, and sharing benchmark pages. It also supports TypeScript and deeper runtime analysis.

What is the difference between jsPerf and a simple benchmark playground?

jsPerf focuses on saved benchmark pages, revisions, browser results, and optional deeper analysis from QuickJS, V8, Node, Deno, and Bun.

Can I migrate an old benchmark idea to jsPerf?

Yes. Create a new benchmark page, move shared data into setup, add each approach as a test case, and save the page as a shareable URL.

Does jsPerf support TypeScript benchmarks?

Yes. jsPerf supports JavaScript and TypeScript benchmark snippets, including typed setup and test bodies.
