Kasm Workspaces streams browsers, desktops and apps to any web browser via containers. See pricing, features, pros, cons and alternatives for 2026.
Kasm Workspaces is a container-streaming platform that delivers browsers, virtual desktops, and applications directly into a standard web browser using isolated Docker containers, with no client software installation required. Kasm Technologies was founded in 2017 in McLean, Virginia, by CEO Justin Travis and co-founder Matt McClaskey, with roots in secure collaboration work for US federal and Department of Defense programs.
The platform is built on Kasm's own open-source container streaming technology, including KasmVNC, its web-native VNC implementation, which streams each session as video/pixel data to the browser rather than requiring a locally installed remote-desktop client. This design makes Kasm particularly suited to security-sensitive environments where controlling exactly where data and compute live is critical.
Kasm Technologies remains a privately held, founder-led company with an estimated 25 to 50 employees, and it continues to serve both a large open-source Community Edition user base and a growing roster of enterprise, government, and managed security provider customers on its paid tiers.
Kasm's core capability is Remote Browser Isolation, which opens websites inside disposable, sandboxed containers so malware or malicious scripts never reach the end user's actual device, alongside Desktop as a Service for streaming full Linux or Windows desktops on demand. It also supports secure remote access to internal web applications as a VPN alternative.
A large marketplace of pre-built Workspace images covers browsers like Chrome and Firefox, full Linux desktop environments, and developer tooling, letting admins spin up standardized environments in seconds. DevOps and CI teams use the same container technology to create ephemeral, disposable test and build environments.
Administrative features include session recording and casting for support or compliance monitoring, auto-scaling to handle load spikes, and enterprise authentication via SAML, SSO, LDAP, and Active Directory, making it deployable inside existing enterprise identity infrastructure.
The Community Edition of Kasm Workspaces is completely free for individuals, home-server users, non-profits, and evaluation purposes, though it is capped at 5 concurrent sessions and supported only through a public community issue tracker rather than dedicated support channels.
Commercial editions follow a per-user-per-month model, starting as low as 5 dollars per user per month for personal use and around 10 dollars per user per month for team, enterprise, self-hosted, or private/hybrid cloud deployments, with higher session limits, SSO, and dedicated support available at custom enterprise pricing negotiated directly with Kasm's sales team.

It is a security technique where websites are opened inside disposable, sandboxed containers on Kasm's servers rather than the user's device, so malware or malicious scripts never reach the actual endpoint.
Yes, Kasm can provide secure remote access to internal web applications without requiring a traditional VPN client, streaming access through the browser instead.
Yes, in addition to Linux desktop streaming, Kasm supports streaming Windows virtual desktops as part of its Desktop as a Service capability.
Kasm offers similar desktop and app streaming capability but is built on an open-source, self-hostable container architecture, giving organizations, especially government and security-focused ones, more control over where session data lives compared to Citrix or VMware's more traditional licensing models.
