Kasm Workspaces alternatives
The 6 alternatives below are grouped by kind of sandbox, and each says what it does differently from Kasm Workspaces. Start from whatever made you look: missing GPUs, session limits, self-hosting, pricing or isolation.
Why teams look beyond Kasm Workspaces
A mature container-streaming VDI platform whose Developer API can hand agents isolated desktops, best suited to teams that already operate it.
- Built as VDI and browser isolation for people; the agent story is positioning rather than an agent-specific SDK
- Container isolation only (no VM option documented) and no documented startup figures
- Commercial pricing is not published; the Community Edition is capped at 5 concurrent sessions and non-commercial use
Kasm Workspaces alternatives, by kind
Browser and desktop sandboxes
Hosted browsers and full desktops that computer-use agents click, type and browse in.
Browserless
Managed headless Chrome, Firefox and WebKit over WebSocket for Puppeteer, Playwright and Selenium, with BrowserQL stealth, REST endpoints and a Docker image you can self-host.
- Not documented
- Open source
- Self-hostable
- GPU
How it differs: Existing Puppeteer, Playwright or Selenium automations that want a managed or self-hosted browser pool. A proven managed browser pool for automation code, less tailored to agents than its newer peers and silent on isolation.
Cua
Open-source computer-use infrastructure: Linux sandboxes as gVisor containers and macOS or Windows sandboxes as VMs, run locally, in your own cloud account or as shared "Spaces".
- gVisor container or VM
- Open source
- Self-hostable
- Pause/resume
How it differs: Teams that want open-source computer-use sandboxes on their own Macs, servers or cloud accounts, including macOS VMs on Apple silicon. The broadest open-source option for computer-use sandboxes across macOS, Linux and Windows, now firmly a self-run toolkit after the hosted cloud shut down.
Hyperbeam
Embeddable hosted virtual computers (Chromium browsers, plus Android and console emulators on request) created by REST API and streamed into web apps for multi-user control.
- Not documented
How it differs: Products that embed a shared, streamed browser for users, where an agent may also drive it through the client SDK. A co-browsing embed product rather than an agent sandbox; usable for agent-plus-human browsing but lacking the automation hooks of agent-focused browser services.
Orgo
Always-on cloud Linux and Windows desktops for AI agents, each an isolated VM billed by the second, with a computer-use API, MCP server, SSH, clone and fork.
- Isolated VM (hypervisor not named)
- GPU
- Pause/resume
How it differs: Agents that keep a persistent cloud desktop running around the clock with a browser, terminal and SSH. A persistent-desktop service for computer-use agents with unusually transparent per-second pricing, though isolation details are thin.
Scrapybara
Hosted Ubuntu, browser and Windows desktop instances for computer-use agents, driven through Python and TypeScript SDKs with pause and resume.
- Not documented
- Pause/resume
How it differs: Computer-use agents that need a ready-made Ubuntu or Windows desktop with a browser, bash, filesystem and Jupyter tools in one API. A compact computer-use desktop API with good tooling, but undocumented isolation and pricing and a parent company that has pivoted make it one to evaluate carefully.
Cloud development environments
Cloud and in-browser development environments that coding agents increasingly run in.
Coder
Self-hosted cloud development environments defined in Terraform (VMs, Kubernetes pods or Docker containers) for developers and coding agents, with a control-plane-hosted agent loop so workspaces hold no model credentials.
- Template-defined (VM/pod/container)
- Open source
- Self-hostable
- Pause/resume
How it differs: Organisations that want to run coding agents in self-hosted workspaces on their own clusters and clouds with audit and governance. The leading open-source, self-hosted workspace platform for agents and developers, with isolation as strong as the Terraform templates you write.
