Kasm Technologies provides containerized workspace and browser isolation software (Kasm Workspaces). Licensing governs feature access (community vs. enterprise tiers), deployment scale (concurrent sessions, nodes), support, and entitlements like SSO, persistent workspaces, GPU acceleration, and advanced policies. License keys are the mechanism that activates and enforces those entitlements on deployed Kasm clusters.
The word "top" in your search query implies you are looking for the best possible licensing solution. In the Kasm ecosystem, there is no "Pro Max" or "Ultimate" version—instead, there are two primary paid tiers: Professional and Premier.

Issue A: "Invalid License Signature"
Issue B: "License Expired" even though you just bought it.
Issue C: No HA option visible.

The Role of Licensing in Kasm Workspaces Kasm Workspaces is a leading container-based platform that streams applications and entire Linux distributions to a web browser, providing a secure and scalable environment for remote work. Central to the deployment of its Professional and Enterprise tiers is the activation key, which serves as the primary mechanism for unlocking advanced features and increasing user capacity beyond the free Kasm Community Edition. Licensing Models and Availability
Kasm offers two distinct licensing models to accommodate different organizational needs: Issue B: "License Expired" even though you just bought it
Per Named User: This model is based on the total number of users registered in the system. It is ideal for high-volume users who require guaranteed, constant access.
Per Concurrent Session: This flexible model focuses on the number of active sessions running simultaneously. It is typically better for environments where many users need access at different times. The Activation Process
To upgrade from the Community Edition, users must obtain an Activation Key through the Kasm checkout process. For standard installations, this key can be applied directly within the web application under Diagnostics -> System Info -> Licenses.
In more complex environments, licensing follows specific workflows:
Offline Activation: Installations without internet access require an additional step using the Kasm Workspaces Activation Tool. Users must combine their Installation ID with their Activation Key to generate a unique License Key for offline use.
Automated Deployment: Administrators can pass the activation key to the initial installation script using the -a or --activation-key-file parameter to automate licensing during setup.
Programmatic Management: The Kasm Developer API allows organizations to manage licenses and "seats" programmatically, enabling them to split a single large license across multiple installations. Issue C: No HA option visible
While the Community Edition remains a robust, free tool for non-profits and individual testing—supporting up to 5 concurrent sessions—the transition to a paid license key is essential for enterprises seeking professional support and unrestricted scalability.
