Tool Open source
Swarm Rebuild is a Chrome extension that replaces a web page with a blank canvas and reconstructs it live using a swarm of multiplayer cursors, including drawn boxes, typed text, pen-tool lines, ruler guides, media, and duplicated elements. It is a tribute to Joel Califa's Swarm website.
The extension snapshots the live DOM, including open shadow roots, into a blueprint of styled boxes, text layers, borders, media, repeated elements, and alignment guides. It then overlays the page with an isolated layer and uses task-specific cursor scripts to rebuild the snapshot as the user scrolls; duplicates wait for their master elements, and the swarm uses orbiting, alignment, and mouse-avoiding flocking effects. Synthesized sound effects are generated with the Web Audio API rather than audio files.
It can be activated from the toolbar or with Alt+Shift+S, supports replay, live-page restoration, variable build speeds, and an optional sound mode. The repository also includes a self-contained test page and instructions for loading the extension unpacked. It is dependency-free, distributed as a Manifest V3 extension, and has no license yet; the project notes that parts of the original Swarm site were adapted and reuse should be checked with its creator.

A Chrome extension tribute to Joel Khalifa's Swarm website. Pressing a shortcut wipes the page to a blank canvas and a crowd of multiplayer cursors rebuilds it from a snapshot with synthesized sound effects. Written in JavaScript with no dependencies.
