webKnossos is open-source, so you can install it on your own server. We recommend a server with at least 4 CPU cores, 16 GB RAM, and as much disk space as you require for your datasets.
This tutorial shows how to install webKnossos on a fresh VM which is available over the public internet and has a domain name (or a subdomain) already configured. webKnossos will then be available with over a secured connection (HTTPS) with automatic certificate management.

For installations on localhost, please refer to the Code Readme.
When starting with webKnossos you first need to create an organization. An organization represents your lab in webKnossos and handles permissions for users and datasets. Choose a descriptive name for your organization, e.g. "The University of Springfield", "Simpsons Lab" or "Neuroscience Department".
In the onboarding flow, you are asked to create a user account for yourself. This will be the first user of your organization which will automatically be activated and granted admin rights. Make sure to enter a correct email address.
Without any data, webKnossos is not fun. Luckily, there are some sample datasets that you can download directly from the onboarding screens. Once you've completed the onboarding, you can also import your own datasets.
For small datasets (max. 1GB), you can use the upload functionality provide in the web interface. For larger datasets, we recommend the file system upload. Read more about the import functionality in the Datasets guide.
By default, datasets are visible to all users in your organization. However, webKnossos includes fine-grained permissions to assign datasets to groups of users.
