First run, step by step.

macOS

Download: a .zip of RikuFlow.app, one for Apple Silicon and one for Intel. Requires macOS 13.5 or later.

1. Unzip the download and move RikuFlow.app to Applications.
2. Open it. macOS says “Apple could not verify” the app. Click Done.
3. Open System Settings → Privacy & Security, scroll down and click Open Anyway.
4. Confirm once more. From now on it opens normally.

Since macOS 15, right-click → Open no longer bypasses the check. Use Open Anyway in Privacy & Security.

Windows

Download: a .zip. Requires Windows 10 or 11.

Either unblock the zip before extracting:

1. Right-click the downloaded .zip → Properties.
2. Tick Unblock at the bottom, then OK.
3. Extract the zip and open RikuFlow.exe.

Or, if you already extracted it, when SmartScreen appears:

1. Click More info.
2. Click Run anyway.

Linux

Download: a .tar.gz. Requires glibc 2.28 or later.

tar xzf rikuflow-*.tar.gz && ./rikuflow/rikuflow

An optional script in the folder adds a desktop entry so RikuFlow shows up in your app launcher.

After the first launch

• RikuFlow opens in your browser at a local address on your own computer.
• Paste the key from your email to activate. After activation it works offline.
• Connect a provider in Settings, create a project, and run your first node.
• Updates are offered inside the app with their release notes. A backup is taken before each update, and a failed update rolls back on its own.
