Level Up Tutorials is the online course platform of Scott Tolinski, a US developer best known as the co-host (with Wes Bos) of the long-running Syntax podcast. Level Up Tutorials has been publishing modern web-development course material continuously since 2012 — one of the longer-running independent course platforms in the JavaScript ecosystem.
The course catalog covers the modern full-stack JavaScript landscape: React (including Next.js), Svelte / SvelteKit (Scott has been a long-running advocate for Svelte), Vue, GraphQL, Node.js, MongoDB, the testing tracks, Tailwind CSS, animation patterns, and the surrounding tooling. Material is structured around long-form project-based tutorial series rather than disconnected feature videos.
The CourseFlix listing under this source carries over 10 Level Up Tutorials courses spanning that range. Material is paid; Level Up Tutorials runs on a monthly / annual subscription on the original platform. Courses are aimed at intermediate-and-up web developers.
