Most browsers are resource hogs. Externo was built from the ground up to stay out of your way — so your RAM, your CPU, and your frame times go to the game, not the browser.
Who we are
Externo started because every browser out there treats background processes like they're free. They're not — especially when you're mid-game and suddenly drop frames because your browser decided it was a great time to sync, update, or phone home.
We built Externo to be the browser you leave open while you game. It sits quietly, uses what it needs, and nothing more.
"Your browser shouldn't cost you frames, RAM, or focus. Externo doesn't."
Built for gaming
When you're not actively browsing, Externo throttles itself down. No background JS loops, no hidden processing eating into your game's CPU budget.
Chrome and Edge can eat gigabytes of RAM with a handful of tabs. Externo keeps its footprint tight so your game gets the memory it needs.
Externo doesn't auto-update in the background and demand a restart at the worst possible moment. You update when you want to.
Pop over to look something up mid-session and get back in seconds. No loading spinners, no startup bloat, no waiting.
We don't collect usage data, crash reports, or anything else. Your browsing is yours. Nothing leaves your machine without you knowing.
Built specifically for Windows. It integrates cleanly with the OS, doesn't fight system resources, and behaves the way a Windows app should.
