I kept needing screenshots of apps and websites at multiple sizes — different aspect ratios for marketing, app stores, social posts — and couldn't find a tool that handled it without a lot of manual resizing and re-exporting. So I built one: SimplShot (free, open source, macOS — https://simplshot.com)

Curious how others handle this. Is there a workflow or tool I've missed? And more broadly, is the pain of producing screenshots at multiple sizes for a launch or campaign something others run into, or just me?
