Show HN: Microterm runs Linux VM in any browser tab via WASM, RISCV64 emulation
Xlab Sunday, February 22, 2026
Microterm is a fully compliant Linux virtual machine that runs in any browser tab. It is designed for real development and operations workflows, not demo-only terminal output. You can use it on desktop, tablets, and phones, including iOS home-screen PWA installs.
Under the hood, Microterm combines Restty (libghostty + WebGPU) web terminal rendering and a TinyEMU-backed Alpine Linux guest on RISC-V64. The VM image is chunk-loaded in the browser and booted locally.
I successfully used it to run Codex directly without leaving an in-app preview inside X app or Telegram :) Can be used to SSH to any server, play with Kubernetes and Tailscale.
Let me know what you guys think!!
