Description
Hey HN!As a developer, I got frustrated with the screenshot workflow for documentation: Open DevTools → Set viewport size → Take screenshot → Switch tabs → Download → Open editor → Annotate → Save → Repeat...Built ZScreenshot - a sidebar extension that keeps everything in one place. Set viewport once, capture instantly, edit in sidebar. No tab switching, no DevTools.Free: • Custom viewport (consistent screenshot sizes, no sidebar interference) • Full-page capture (scrolling pages) • Tab recording with audio • Privacy-first (all local processing except authentication)Pro (14-day free trial, no credit card): • Image editor (arrows, shapes, text, blur, emoji - instant annotations) • Collection (merge multiple screenshots for comparisons) • Bulk ZIP download • MP4 exportEverything happens in the sidebar: Capture → Edit → Download → Access history anytime.Why no "select area before capture"? OS tools (Win+Shift+S, Cmd+Shift+4) already do this perfectly. ZScreenshot focuses on what they can't: viewport control, instant editing, history management. Plus, crop-after-capture gives more flexibility.Chrome Web Store: https://chromewebstore.google.com/detail/zscreenshot/jdgmjck...

Could you build this?
Yes It is a browser extension using the `chrome.debugger` or `chrome.tabs.captureVisibleTab` APIs with Emulated Media/Device Metrics overrides to capture specific viewport sizes and run an image canvas editor.

Same idea, different domain
Nobody's really built a dev tools tool for Sales yet.
