Frontend Masters is the dominant subscription video platform for advanced JavaScript and front-end engineering, founded in 2012 by Marc Grabanski and headquartered in Minneapolis. The platform's distinctive contribution is the workshop format: each course is a full-day or multi-day in-person workshop recorded with a live audience, taught by working senior engineers from Vercel, Netflix, Google, and the broader JavaScript-tooling ecosystem.
The roster includes some of the most cited educators in the field — Kyle Simpson (You Don't Know JS), Brian Holt, Jen Kramer, Will Sentance, Steve Kinney, Lukas Ruebbelke, Marcy Sutton, Bianca Gandolfo, Maximiliano Firtman, and many others. Course material covers the full modern web stack: React, Vue, Svelte, Astro, Node.js, TypeScript, accessibility, web performance, computer science fundamentals, and the build / tooling layer.
The CourseFlix listing under this source mirrors a substantial slice of the Frontend Masters catalog — over 160 courses in active rotation. Material is paid; Frontend Masters itself runs on a monthly / annual subscription model on the original platform. Courses range from beginner web fundamentals through senior-level architecture and CS-foundations material.
