Environment Details for Better Bug Reports

Developers can’t fix what they can’t reproduce. This page reads your browser, operating system, screen, pixel ratio, language, time zone, GPU and feature support and formats it for Jira, GitHub, Slack or email, so every bug report starts with the environment.

What you can do

  • One-line summary for a bug title, such as “Chrome 141 on macOS 15 · 1512×982 @2x”.
  • Copy as a Markdown table, plain text or JSON.
  • Add the page URL, app build and test account before copying.
  • Shows viewport size, zoom, color scheme, reduced-motion, touch, storage and WebGL/WebGPU support.

Good to know

  • Resize the window and the viewport values update live, so you can capture the size where a bug appears.
  • Chromium browsers share extra details like OS version and architecture; Safari and Firefox share less on purpose, and the page says “Not exposed” when something is hidden.
  • Everything is read locally and nothing is sent to a server.

Frequently asked questions

What should a bug report include about the environment?

At minimum the browser and version, operating system, screen or viewport size, and the page URL. Time zone, language and device type often explain data and layout bugs.

Why do some fields say “Not exposed”?

Browsers limit what they reveal to protect privacy. Chrome and Edge share more than Safari and Firefox.

Is any of this uploaded?

No. Detection runs entirely in your browser.

How do I report the size of my browser window?

Use the Browser viewport value. It is the size of the page area, which is what responsive layouts react to.
