Microterm: The Ultimate Free Linux VM in Your Browser & Pocket

Microterm is a fully functional Alpine Linux virtual machine running directly in any browser tab. It is built for real development work on desktop and mobile, including iOS and Android PWA installation and persistent local storage up to 40 GB.

Microterm uses Ghostty terminal rendering on the web and boots a TinyEMU-backed RISC-V64 Linux VM. This is local computation with maximum privacy: your workloads run on your own device.

Why Choose Microterm

• Free Linux VM on your phone, tablet, and desktop browser.
• Local-first private compute model for coding, testing, and learning.
• Persistent storage up to 40 GB for long-running tasks and datasets.
• Real networking for SSH, Nginx hosting, Linux networking labs, and Kubernetes learning workflows.
• Tailscale connectivity to securely connect your pocket VM to other devices.
• Support for RISC-V64-compatible container payloads and Docker-style workflows.

Built-In Software & Utilities

Alpine Linux (full userspace), bash, coreutils, sudo, htop, iptables, fastfetch, git, make, micro, sqlite, jq, ripgrep, brotli, vips-tools, curl, openssh-client, nginx, croc, nodejs, npm, Codex, and JavaScriptCore runtime (Bun integration WIP).
