Fireship: Jeff Delaney's coding and AI channel

Jeff Delaney's Fireship channel has 4.28M subscribers for fast coding and AI explainers; its courses moved to fireship.dev after the 2026 ui.dev merger.

Fireship is the YouTube channel and online persona of software developer Jeff Delaney, whose channel page dates from 7 April 2017. It is known for a fast-cut editing style and for the formats "100 Seconds of Code" and "The Code Report", which compress programming concepts, framework releases and AI news into short videos; the channel now has 4.28 million subscribers across 843 videos. The channel started on web and mobile development — Firebase, JavaScript frameworks, general programming — and has steadily added AI tools, large language models and AI coding assistants as those topics took over developer discussion. Delaney also built the companion course platform Fireship.io, whose address now resolves to fireship.dev. In January 2026 Fireship and ui.dev, Tyler McGinnis's course company, announced they were joining forces: ui.dev's content and platform moved onto fireship.dev and a subscription to either side now covers both course libraries. Delaney wrote that he keeps creative control over what the team makes and still works on and voices every video.
