Web Client
If you're a macOS user, you can only use the Web Client.
Installation on macOS
Download the correct updater for your Mac and place it in an empty folder in your file system.
You could also directly download OpenBullet2.Web-osx-x64.zip or OpenBullet2.Web-osx-arm64.zip, but the updater is recommended since it can be used to easily update your installation in the future.
- x64
- arm64
Open a terminal and cd into the folder where you placed the updater. Then execute the following commands:
chmod +x ./ob2-web-updater-osx-x64
./ob2-web-updater-osx-x64
Open a terminal and cd into the folder where you placed the updater. Then execute the following commands:
chmod +x ./ob2-web-updater-osx-arm64
./ob2-web-updater-osx-arm64
If macOS blocks the updater because it is from an unidentified developer, try to open it once, then go to System Settings > Privacy & Security and click Open Anyway for the blocked app.
Once the updater has finished downloading the latest version of OpenBullet 2, execute these commands to start the application:
chmod +x ./OpenBullet2.Web
./OpenBullet2.Web
If macOS blocks the app on first launch, use the same Open Anyway flow in Privacy & Security and start it again.
Wait until it prints the text you see in the picture below.

Finally, navigate to http://localhost:5000 using your favorite browser and you should see the home page.

Troubleshooting
macOS says the app cannot be opened
This is expected for unsigned binaries on macOS. Try to run the updater or app once, then open System Settings > Privacy & Security and click Open Anyway for the blocked executable.
I downloaded the ZIP instead of the updater
Unzip the archive, open a terminal in that folder, then run:
chmod +x ./OpenBullet2.Web
./OpenBullet2.Web
