Claude needed a strikethrough the slide app did not have, so it added one to the app. Asked to build a deck from a Google doc, it also added text centering and a box that accepts raw SVG, then generated the SVG for a diagram the app could not otherwise draw. That is Kenton Varda's argument in a single move. Software today ships from a developer to users whose feature requests die in Jira, and the escape hatch developers reach for is a plugin architecture rewrite that takes years and never lands. If a user's own agent can add the feature, the core app stays clean and nobody waits. Nothing in current infrastructure supports that. Mobile platforms will not run unsigned code, and 25 years of cloud architecture put one blessed version of every app on the developer's server. Gadgets is his answer, built on Cloudflare Workers with no containers and no database. Each gadget is a single instance of an app, one deck or one board, and sharing is implemented by the platform so the app itself cannot get access control wrong. The UI runs in a null origin iframe that can only postMessage to its parent, over a Cap'n Web RPC session to server code in a dynamic worker sandbox, so an XSS bug in vibecoded code has nothing left to leak. The whole demo ran locally on workerd, so a dead conference network cost him only the one call that needed a model.
