Orkestral ships as a native desktop app for the three major platforms. The local models come bundled inside the installer, so the app works fully offline from the first launch, no extra download.

​
Download

Download for macOS

Apple Silicon (M1+) · .dmg

Download for Windows

x64 · .exe (installer)

Download for Linux

x86_64 · .AppImage
You can also grab any installer from the releases page.
The installers are large (~1.7–2 GB) because the local execution model (the Forge) ships inside the app, so it runs offline from the very first launch.

​
Install by platform

  1. Open the .dmg and drag Orkestral to Applications.
  2. The first time, macOS may warn that the developer is unverified, right-click the app and choose Open (or System Settings → Privacy & Security → Open anyway).
  3. Open Orkestral.
Builds are not code-signed yet, so the OS shows a one-time warning on first launch. It’s safe, there’s just no developer certificate yet. Code signing and notarization are on the roadmap.

​
First launch

On the first run, Orkestral sets up its local models, the Forge (code execution) and embeddings (semantic search). Since they’re bundled, this is a quick local step, not a big download. Everything is stored under ~/.orkestral (database, workspace files, models).

​
System requirements

  • macOS 12+ (Apple Silicon), Windows 10/11 (x64), or a modern Linux x86_64 distro.
  • ~4 GB of free disk space after install.
  • For premium adapters (optional): the Claude Code (claude) and/or Codex (codex) CLIs installed and authenticated. The Forge needs nothing extra.
