Automatic Device & Browser Details
Every bug report includes browser name, version, OS, viewport size, screen resolution, and page URL. No more asking “what browser are you using?”
Callout automatically detects the user's browser, operating system, viewport dimensions, screen resolution, and current page URL. This environment data is included in every bug report so your team can reproduce browser-specific or viewport-specific bugs without asking the user for any technical information.
Environment data
collected instantly.
No user input. No forms to fill. Just automatic detection.
Browser and OS detected
Callout reads the user agent string and browser APIs to identify the exact browser name, version, and operating system. Chrome 120 on macOS 14.2, Firefox 121 on Windows 11 — it is all captured automatically.
Viewport and screen measured
The current viewport dimensions, screen resolution, and device pixel ratio are read from the browser. This tells your team whether the user was on a small mobile screen or a large desktop monitor.
Page URL recorded
The exact page URL where the bug was reported is captured. Your team knows the precise route, query parameters, and hash fragment — no need to ask the user which page they were on.
Reproduce bugs
on the first try.
No More “What Browser?”
The most common follow-up question on bug reports is eliminated. Browser name, version, and OS are automatically included. Your team never needs to ask.
Catch Viewport-Specific Bugs
Layout issues often depend on viewport size. With exact viewport dimensions and screen resolution in every report, your team can match the user's display conditions precisely.
Know the Exact Page
The full page URL — including path, query parameters, and hash — is captured. Your team opens the same URL and starts reproducing immediately, no back-and-forth.
Faster Triage
Device details are formatted as a scannable list in the issue. Browser, OS, viewport, resolution, and URL are each on their own line. Your team can glance at the environment in seconds.
Common
questions.
What device and browser details does Callout capture?
Callout captures browser name and version, operating system, viewport dimensions, screen resolution, device pixel ratio, and the current page URL. All of this is detected automatically from the user agent and browser APIs.
Does the user need to provide their browser details manually?
No. Callout detects all environment details automatically. Users never need to check their browser version, look up their OS, or copy their URL. Everything is captured behind the scenes and included in the report.
Why are browser details important for bug reports?
Many bugs are browser-specific or viewport-specific. Knowing the exact browser version, OS, and screen size helps developers reproduce the issue faster. Without this information, teams waste time going back and forth asking users for environment details.
How are device details displayed in the bug report?
Device details are formatted as a clean, readable section in the GitHub issue (or Linear/Jira ticket). Each detail — browser, OS, viewport, resolution, URL — is listed on its own line for quick scanning during triage.
