CstWeave is an on-device Chrome extension designed for fast, private tab region recording. Developed by indie hacker FujiDevv, it allows users to quickly snip any area of a browser tab and export high-quality recordings without relying on external servers.
Using CstWeave is straightforward: simply draw a rectangle over any area of a tab to capture it. The tool supports exports in clean GIF formats as well as HD WebM videos complete with system audio. Because the entire process runs 100% on-device using Chrome Offscreen Documents, users experience zero tab lag during capture.
Privacy and speed are central to CstWeave's functionality. There are no cloud uploads, no server rendering queues, and no watermarks added to your clips. CstWeave offers a Lite version that is free forever, alongside a Pro tier available for a $9.99 lifetime payment.
