Open OpenKernel EDU What do you get with OpenKernel EDU?
A named system of 4 components — not a list of features, a description of what the software actually does.
Assembly Playground
Write, step through, and debug x86 assembly with instant in-browser feedback. No toolchain to install, no compiler to configure, no account required.
Teacher Dashboard
Assign modules, track student progress, and review submissions — all in-browser, zero IT setup required. Any device with a browser qualifies.
CS Fundamentals Pack
Aligned to core CS concepts: data structures, algorithms, OS basics, and networking. Usable from grade 9 through introductory university courses.
Who built this, and why does it work?
Used in classrooms and libraries where IT constraints make conventional tooling impractical. Any modern browser is the only requirement — no installation, no accounts.
