Rune

Rune is a code editor and a terminal multiplexer in one native window. Editors, terminals, and an AI agent sit side by side across nine workspaces, and Rune Network opens a project living on another of your machines as if it were local. GPU-accelerated, no Electron, GPL v3. It was built in private and opened up in September 2026.

It runs on macOS 13.3 or later and Linux with glibc. No Windows, no Alpine. Install is a curl script or a DMG. Vim, Emacs, and standard keymaps are built in. Language support is the limit: Go and Python are fully supported, Rust and Zig are beta, TypeScript is still on the roadmap, and 300 other languages get syntax highlighting only. The agent is a separate install and takes OpenAI, Anthropic, Gemini, or Bedrock keys, a ChatGPT or Claude subscription, or local models.

Solo: free, including Rune Network for 2 connected machines. Rune Pro is $10/mo or $100/yr for 10 machines and premium support. Enterprise adds SSO, SCIM, and running the network stack on your own servers, by quote. TypeScript shops should stay on zed-industries/zed or microsoft/vscode for now.

The catch: telemetry is on by default, and it includes your machine's host name. Remote access needs a Rune account and runs through the company's coordination server unless you pay for Enterprise.
