SWACN is a tool that turns terminal recordings into interactive, bootable sandboxes. If you’ve ever used asciinema, you know it’s great for watching a CLI tool in action. SWACN takes that a step further: it captures your terminal session and its filesystem into a tiny, client-side Linux VM (running in WASM). Your audience doesn't just watch a video; they can "flip" the recording and actually use the tool themselves right there in the browser.
