Introducing Web Applets, Rupert Manfredi

February 24, 2025

Natural language UIs are touted by many to be the future of user interfaces. But right now, they still look a lot like the past: a text-based prompt, with text-based answers. (If you squint, it could be MS-DOS.) While there’s growing support to bring richer, more graphical interfaces to these systems, they mostly rely on proprietary, centralized integrations. Will the future of computing look like a handful of privately controlled platforms, or an open thriving ecosystem like the web?

Web Applets are a new open standard for allowing language models to use rich, graphical software, built upon the web.

They are small, local-first, interoperable bits of software that can be used and read by both a human and a machine. This talk introduces the problem that Web Applets aims to solve, shows how they work, and reveals a few examples in action. Attendees will be encouraged to integrate Web Applets into their own applications and collaborate with us in shaping the technology’s future, to help keep software open!

Rupert Manfredi thinks a lot about the future of the human experience of the Web and technology. He’s worked at Mozilla, Google and elsewhere on the ideas and is now developing an open Web based platform for AI agents to interoperate.

Here he talks about Unternet, that platform.
