Opera Desktop brings Maestro to your computer, on Windows, macOS and Linux. It can also host a Sampler Hub for your other devices, and keep your conversations, settings and providers in sync with them.

Install a release

Download your build from the download page or from the latest Opera release:

Platform File Install
Windows x64 opera-windows-x86_64-setup.exe Run the installer. It installs for your user only, no administrator rights needed.
Windows ARM64 opera-windows-aarch64-setup.exe Same installer, built for Snapdragon and other ARM PCs.
macOS (Apple silicon) opera-macos-aarch64.dmg Open the disk image and drag Opera to Applications.
Linux x86_64 opera-linux-x86_64.AppImage or .deb Make the AppImage executable and run it, or install the package with sudo apt install ./opera-linux-x86_64.deb.
Linux arm64 opera-linux-aarch64.AppImage or .deb Same as x86_64.

If a build is not available for your platform, run Opera in the browser or build it from source.

Run from source

You need Node.js and npm. A Rust toolchain is only required for the Tauri desktop shell, which also builds against a Sampler-Hub checkout placed next to the Opera repository.

Terminal window
npm install
npm start

From the Expo dev server you can:

  • press w to open the web build;
  • press a for Android.
Terminal window
npm run web
npm run desktop         # Opera Desktop against the dev server
npm run build:desktop   # installer for the current machine

The web build runs in any modern browser. On the web, Opera can use the browser’s built-in model, a remote OpenAI-compatible endpoint, or Whisper for local speech recognition.

Host Sampler Hub from desktop

The desktop app can run a Sampler Hub without a separate installation:

  1. Open Settings → Sampler Hub.
  2. Choose Host the hub here.
  3. Pair your phone or browser with the code shown by the app.

This is the quickest way to try sync and shared models. For an always-on hub, install the standalone service instead: Sampler Hub.

Desktop behaviour

  • Local storage. The desktop shell uses the same SQLite-backed store as the app. Your data stays in the app’s data directory.
  • Local providers. Ollama and OpenAI-compatible servers are reached over the network you configure. A local server on the same machine is the lowest-latency option.
  • Updates. Opera checks the latest GitHub release and shows a notice at the top of Settings when a newer version is out. Install it over the current one, your data is kept. On the first launch after an update, a What’s new sheet shows the release notes. Source builds update with git pull and a rebuild.
