Exacto: Resize windows to exact pixel-perfect dimensions instantly.

Hi Product Hunt! 👋

Ever found yourself dragging your browser window edge back and forth, trying to hit that exact 768px breakpoint? Yeah, me too. That's why I built Exacto.

I'm Jun, maker of Exacto. As a developer, I got tired of the endless cycle: drag the window, open DevTools, check the size, adjust, check again... I had the same problem recording tutorial videos—trying to get every window capture to match across scenes. My streamer friends dealt with it too: their OBS layouts would break every time a window changed size by a few pixels. We didn't need another generic window manager—we needed a precision tool.

Who needs Exacto?

Web developers testing responsive designs at exact breakpoints (375px, 768px, 1440px...)
Streamers who need pixel-perfect OBS layouts every single time
Designers doing QA between Figma specs and actual implementation
Content creators capturing screenshots for App Store assets or social media formats

Here's what makes Exacto different:

Eliminate Guesswork: Set your window to exact dimensions (like 375x667 for iPhone SE or 1920x1080 for recordings) instantly via hotkeys—no more dragging and measuring.
Lightweight & Fast: Stays out of your way until you need that perfect size.
Fair Pricing: No subscription fatigue. Just a simple one-time purchase.

Whether you're testing your mobile breakpoint, setting up a professional stream, or preparing screen recordings at exact specs, Exacto ensures your windows are exactly where—and what size—they need to be.
