JSLinux

JSLinux is a RISC-V emulator written by Fabrice Bellard. It enables you to run Linux in your web browser.

Each program takes a few seconds to load the first time, depending on your internet speed. But once loaded they are quite usable on a modern computer. On my M1 Mac Mini in Chrome it runs my Primes benchmark in 190 seconds, comparable to a 200 MHz single-issue RISC-V CPU.

There are versions with Fedora 33 or Buildroot, console or X Windows.

Both Fedora and Buildroot have the GNU toolchain installed so you can write and build C or assembly language programs and run them. There is objdump to disasemble the binary code. Both include sample C and Python programs.

Fedora of course has a lot more software included, including emacs, vi/vim, nano, wget and curl, git, ssh&scp. So you can grab things from the internet and try them.

RISC-V Fedora Linux console version

See the main JSLinux page for other versions.

You can also download the underlying TinyEMU and Linux disk images and run them on your own computer.
