Quick start

From payment to a running app in about five minutes.

1. Get a license key

Pay $19 via Wise from the pricing section. Then email [email protected] with your Wise transaction ID and the address you want the key sent to. We verify the payment and email your key, normally within 24 hours.

2. Install

Pick your platform on the download page, or run:

# macOS and Linux
curl -fsSL https://usingopen.com/install.sh | bash

# Windows PowerShell
iwr -useb https://usingopen.com/install.ps1 | iex

The installer asks for your key, downloads the build through the licensed endpoint, and verifies the SHA-256 before installing.

3. Clear the first-launch warning

The builds are not signed yet. On macOS, Gatekeeper asks you to confirm; on Windows, SmartScreen does. The macOS and Windows guides show the exact steps.

4. Start the app

Launch UsingOpen Studio and follow the first-run screen. If anything fails, the troubleshooting guide covers the common cases, and [email protected] reaches a human.
