Vendor release data
Vendor release data
This compares reported versions with vendor releases, not security fixes or vehicle update eligibility. ESR and staged rollouts may differ.
Reported values can be rounded, hidden or spoofed. API presence does not promise permission or successful use.
Compare your reported version with stable releases.
How to use
- Open this page on the device you want to inspect.
- Read the reported browser and expand a section for details.
- Open the Chrome or Tesla view to compare Chromium releases.
How it works
Your browser reports its identity through a user-agent string and, where available, client hints. Full version hints take priority; a string ending in 0.0.0 may reveal only the major version. Other sections show the capabilities this page can read without asking permission.
Update comparisons use official vendor release feeds. Versions are compared number by number: 120.10 is later than 120.9. The major-version gap is the current major minus your major, with a minimum of zero. Release-date gaps use the earliest Chrome serving dates available for both majors, divided by an average month.
A browser may hide its brand, reduce device details or report another browser for compatibility. An unidentified Chromium browser might be a private derivative. Screen dimensions are CSS pixels, storage estimates concern this website, and media results describe fixed sample formats. None of these readings proves hardware performance or security.
Worked example
How far behind is major 120 when stable is 125?
- Subtract the reported major from the stable major: 125 − 120 = 5.
The example is 5 major versions behind. Matching majors alone cannot establish patch currency.

Frequently asked questions
Which browsers have update comparisons?
Official feeds cover Chrome, Firefox desktop, Edge desktop, Brave desktop and Vivaldi for Windows. Missing product versions remain unknown.
What does major matches mean?
The visible major matches stable, but the browser concealed its patch version. It is not a full up-to-date verdict.
Why is my version newer than stable?
You may be using a preview release, or the browser may report an altered version. The page cannot identify the release channel reliably.
Does this check Firefox ESR?
No. ESR has a separate support schedule; an older number can still receive fixes.
What happens if a feed is unavailable?
Other providers still work. Stale or missing release data cannot establish update status.
