jor1k is an OpenRISC 1000 (and RISC-V) CPU emulator written in JavaScript that boots and runs Linux entirely in a web browser. It supports features like SMP multi-core emulation and is used in interactive demos such as editing, compiling, and running C code online.
Use cases
- run linux in the browser without installing anything
- emulate openrisc 1000 cpu in javascript
- edit compile and run c code online in a browser vm
- demo symmetric multiprocessing with multiple emulated cores
- teach operating systems and systems programming with a browser-based vm
- try rtems real-time operating system in a browser
- test a risc-v cpu implementation in the browser
When to choose
- you need a zero-install browser-based linux environment for teaching or demos
- you want to experiment with OpenRISC or RISC-V emulation without native tooling
- you want to embed a runnable VM in a web page or educational course
When to avoid
- you need high-performance or cycle-accurate emulation for real hardware work
- you need to run modern x86/ARM software or full desktop distributions
- you need a maintained general-purpose virtualization solution
