Hey Product Hunt! 👋 I'm Fuji, creator of CstWeave! Why I Built CstWeave Like many of you, I share dozens of quick UI tweaks, bug clips, and demo snippets every week with my team. But existing tools drove me nuts: Cloud Recorders (Loom, Vidyard): Upload your screen data to third-party servers, take 30+ seconds to generate a link, force monthly subscriptions, and choke on sensitive internal data. Desktop Recorders (CleanShot, ScreenToGif): Great, but heavy—and requires alt-tabbing, full desktop permissions, or Mac-only setups. I wanted something instant, hyper-focused, and 100% private that lives directly inside Chrome. What Makes CstWeave Unique? Instead of streaming your viewport to a remote server queue, CstWeave encodes video frames 100% locally in your browser's RAM using Chrome's native Offscreen Document API (chrome.offscreen). Snip Any Region: Hit Alt+Shift+G (Option+Shift+G on Mac), draw a box over any tab element, and hit record. Zero Cloud & Zero Uploads: Your media frames never leave your machine memory. Period. Instant Export: Save high-FPS WebMs with system audio or Floyd-Steinberg dithered GIFs the exact millisecond you hit stop. No Watermarks / No Monthly Subscriptions: Lite is free forever; Pro is a simple $9.99 one-time lifetime license. Try It Out & Let Me Know! We built CstWeave to give creators, developers, and designers complete control over their screen snippets. I'd love to hear your feedback, feature requests, or favorite workflows! What's the first tab region you're going to snip today?

Love that it's all on-device, no cloud roundtrip is a huge plus for anyone working with sensitive stuff. One thing that would make it even more useful for tutorials: a built-in option to add simple keystroke captions or callouts after recording, so I don't have to drop the file into a separate editor. Would seriously cut my workflow in half.

@travis_hu Thanks! Keystroke visualizers and simple callout overlays are a huge workflow booster—adding this to our feature roadmap for upcoming updates!

Drawing the rectangle is fine but it would be great if I could also schedule a recording to start and stop at set times, so I can capture longer walkthroughs without having to babysit the tab.

@auditpro That's a really interesting use case! Scheduled start/stop timers would definitely save time on longer recordings. Appreciate the feedback!

the on-device rendering with no cloud upload is a really thoughtful call, especially for anyone recording internal dashboards or sensitive work. love that lifetime price too.
