Every third-party script, every DOM mutation, every JSON parse runs on the one thread that also has to paint pixels and answer clicks, and browsers give you exactly one escape hatch: Web Workers. The problem is that Workers are hostile to work with — <code>postMessage</code> and structured cloning make even a counter tedious. Three open-source projects exist to fix this, and they fix <em>different</em> problems: Comlink (12,784 stars) removes the RPC boilerplate, Partytown (13,762 stars) moves third-party scripts wholesale, and worker-dom (3,263 stars) relocates DOM itself. Picking between them without knowing which layer each one owns is how teams end up with a worker architecture that&rsquo;s slower than the original.</p>
