Addy Osmani

Bio

Addy Osmani writes on the web platform from the engineering side — performance, developer experience, what the browser is actually doing under the hood. His distinctive turn over the last year has been to translate platform thinking into the AI-native era: when the consumer of your web pages is increasingly an LLM agent rather than a human, the assumptions that govern frontend craft (rendering speed, navigation flow, visual hierarchy) stop being load-bearing in the same way, and a different set of platform affordances start mattering — agent-permissions, llms.txt, capability declarations, token-efficient TL;DRs, copy-as-markdown buttons.
