ZScreenshot – Capture any viewport size without browser resize
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.

Hey HN!

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 export Everything 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...

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
