For enterprises, a single server is a single point of failure. The Premier license enables Active-Active clustering. You can run Kasm across three or more servers. If one server dies, the session migrates. This is non-negotiable for business-critical remote access.
Let's clear up confusion around the "top" keyword.
Myth 1: "The license key is annual." Reality: Kasm licenses are typically annual subscriptions. You pay yearly for support and updates. However, the software itself does not "brick" if you stop paying; you just lose access to the Enterprise repository updates and support.
Myth 2: "A license key unlocks more CPU power." Reality: Licenses do not unlock computational performance. Performance is entirely based on your own hardware (CPU, RAM, GPU). Licenses unlock features (SSO, clustering, persistence). kasm license key top
Myth 3: "There is a 'Kasm License Key Top' generator online." Reality: These do not exist or are malware. Kasm uses asymmetric cryptography (public/private keys). No website can generate a valid signature without Kasm’s private signing key.
A new table licenses will be created to store key information.
CREATE TABLE licenses (
license_id INT PRIMARY KEY AUTO_INCREMENT,
license_key VARCHAR(255) NOT NULL UNIQUE, -- Stored as hashed value
customer_name VARCHAR(255),
max_sessions INT DEFAULT 0,
expiration_date TIMESTAMP,
license_type ENUM('Trial', 'Standard', 'Enterprise', 'Platinum'),
is_active BOOLEAN DEFAULT TRUE,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);
Understanding the edition is fundamental to any discussion of license keys. For enterprises, a single server is a single
| Edition | License Key Required? | Primary Users | Key Features | | :--- | :--- | :--- | :--- | | Community Edition (CE) | No | Developers, homelabs, small teams | Unlimited concurrent users (but limited to 5 nodes), no persistent profiles, no SAML/OIDC SSO, no support. | | Professional Edition | Yes (perpetual or subscription) | SMBs, departmental deployments | Persistent user profiles, role-based access control (RBAC), premium support, advanced session recording. | | Enterprise Edition | Yes (annual subscription) | Large organizations, MSSPs | High Availability (HA) clustering, SAML/OIDC/LDAP/SCIM, API rate limit customization, dedicated support SLA, usage analytics. | | SaaS (Kasm Cloud) | Not applicable (subscription to cloud) | Teams avoiding self-hosting | Fully managed, automatic updates, no infrastructure management, license included in monthly fee. |
Top Takeaway: If you need more than 5 nodes, persistent data, or enterprise authentication, you must obtain a valid license key for Professional or Enterprise.
