How to download and start OpenBullet 2



In this guide, I will explain all the steps required to install and run OpenBullet 2 on your system. This can be achieved in several ways.


Running a precompiled build

If you don’t want to mess with docker and don’t want to compile your own build, you can use the latest automatically compiled build available on github.

First of all visit this page 562 and download the file (do not select the source code option). Once you downloaded it, unzip it to a folder of your choice.

Now it’s time to install the core runtime 545. You can find instructions on how to install it on your system at the link provided.

When you’re done, you can test if it got installed properly by opening a command prompt and typing dotnet --version, which should output a version number like 5.0 or above.

Navigate to the folder where the file OpenBullet2.dll is located (the one you just unzipped) and launch it by using the following command:

dotnet ./OpenBullet2.dll

If you’re on Windows, you can double click on OpenBullet2.exe instead to achieve the same result.

You should now be able to navigate to http://localhost:5000 on your browser in order to see the OpenBullet 2 setup screen.

Using docker

Install docker from Get Docker | Docker Documentation 74
Create a local folder called UserData where your settings will be stored and run

docker run -p 8069:5000 -v UserData:/app/UserData -it openbullet/openbullet2:latest

and finally navigate to http://localhost:8069 to access your dockerized OB2 instance!

Let’s break down the docker command:

-p 8069:5000 will map your local port 8069 to the container’s port 5000 where OB2 is listening

-v UserData:/app/UserData will map your local UserData directory to the UserData directory inside the container so that even if you switch container in the future you won’t lose your settings

-it will start an interactive shell that lets you see the output of the OB2 webserver for debugging purposes. You can remove this if you don’t care about it.


Compiling your own build

Install git from Git - Downloads 93.
Install the .NET 5 SDK (not runtime) from Download .NET 5.0 (Linux, macOS, and Windows) 545
Open your favourite terminal (or git bash) and run

git clone

now cd into the folder where OpenBullet2.csproj resides

cd OpenBullet2/OpenBullet2

and compile OB2 using

dotnet build --configuration Release

you can then navigate to the build folder and start OB2 with the usual command

cd bin/Release/net5.0

dotnet ./OpenBullet2.dll
