Latest Chrome User-Agent API

Every web scraper eventually hits the same silent failure: the hardcoded User-Agent string in your code slowly goes stale. Chrome ships a new stable version roughly every four weeks, and a UA claiming to be Chrome/109 in a world where everyone else is on Chrome/138 is an easy flag for Cloudflare, Akamai, and even basic server-side filters. You either maintain your own list (and forget to update it), copy one from a gist last edited in 2023, or generate fake strings that get the platform token format subtly wrong.

This API removes that chore. One HTTP call to /latest returns a correctly-formatted, current Chrome User-Agent for the platform you ask for — Windows, macOS, Linux, Android, or iOS — updated with every Chrome stable release. Need variety across a request pool? /random gives you a realistic UA each call, /all returns the full current set, and /platforms lists what's available.

Typical uses:

• Web scrapers and crawlers that need to blend in with real browser traffic instead of announcing python-requests/2.31
• HTTP clients and SDKs that want a sane, current default UA without shipping updates for it
• Automated browsers and bots (Puppeteer, Playwright, Selenium) that override the UA for consistency across a fleet
• Testing and QA pipelines that verify how your own site responds to current Chrome on each platform
