Rune Rune
Rune is a fast, GPU-accelerated, keyboard-driven IDE and terminal multiplexer for macOS and Linux, written in Go with a native OpenGL/Metal graphics pipeline (no Electron). It combines code editing, terminals, CLI tools, language intelligence, debugging, and AI agents in one composable multi-workspace environment, positioned as 'the Unix way, finished as a product' for both manual and agent-driven programming.
Open-sourced under GPL-3.0 on 2026-09-12 with a contributor revenue-share program; repository created 2026-09-10 and at ~1,050 stars within two weeks; latest stable release v1.2.1 (2026-09-11). Linux arm64/x86_64 builds are marked beta, while the macOS Apple Silicon build has been a daily driver for years.
As of
- Native GPU-accelerated UI (OpenGL on Linux, Metal on macOS) with no Electron
- Screen-multiplexer layout: nine workspace slots, unlimited terminals, tabs, and windows
- Built-in coding agent plus IDE-grade skills that external agents can use
- Production-grade language intelligence and debugging out of the box (Go and Python first)
- E2E-encrypted peer network (headscale) to reach any of your Rune instances from any machine
- Plugins and extensions installed from Git repos with `pkg install`, plus official packages
- In-IDE guided tutorial and docs loaded as a workspace the agent can reason over
Power users and terminal-centric developers on macOS or Linux who want an IDE, terminal multiplexer, and coding agent in one fast native app, especially Go and Python developers who work across several machines.
Windows users, teams that need a broad language/extension ecosystem today, or developers who want a familiar VS Code-style editor rather than a keyboard-driven multiplexer model.
Rune is open source under the GPL-3.0 (open-sourced 2026-09-12) and free to install via `curl -fsSL https://rune.build/install.sh | sh`. Unstable Build sells optional hosted services around it (accounts, the headscale-based peer network, official packages) and runs a contributor revenue-share program; the built-in agent uses your own model provider credentials.
Rune is a distinctive take on the AI-native IDE: a native, GPU-rendered multiplexer that treats terminals, language intelligence, and agents as equal citizens rather than bolting chat onto a VS Code fork. It is early as an open-source project and currently strongest for Go/Python on macOS, so evaluate language support and Linux maturity before adopting it as a daily driver.
