Ravada VDI

Ravada VDI is a self-hosted broker for connecting users to virtual desktops. It is best suited to sysadmins who can administer Linux servers and want to manage an on-premise desktop service. Its strongest case is free software with web-based controls; the cost is the technical work of deployment and client setup.

Overview

Ravada brings user access to machines and settings together with administrator controls for VM pools and templates. That gives teams a central web interface for day-to-day access and management, while leaving the server infrastructure in their care.

KVM is the backend it supports today. Although the project is designed to accommodate other hypervisors later, teams using a different backend should not count on that support now. Users need both a browser and a SPICE-compatible remote viewer, so this is not browser-only desktop access.

Key features

• Web-based access and administration: Users can reach their machines and settings, while administrators manage pools and templates. It covers useful VDI controls without replacing server administration.
• SQL and LDAP authentication: Support for both makes Ravada a practical fit for organizations already using either approach to authentication.
• Linux deployment choices: Packages are supported for Ubuntu, Debian and Fedora servers, and Docker is another installation route. The choice helps accommodate different Linux setups, but Linux administration remains part of the job.
• SPICE access: A compatible remote viewer is required alongside a web browser. Documentation covers Linux and Windows viewer clients and includes client setup for macOS, giving users on those systems a documented route to connect.
• Production security guidance: A deployment guide covers SPICE-TLS configuration, a useful resource for administrators planning a production setup.
• AGPL licensing: The code is licensed under AGPL, a relevant consideration for teams adopting or modifying the software.

Pricing

Ravada's Free plan costs nothing and is billed Free to use. It includes self-hosted deployment, Linux-based server administration and the currently stated KVM support. With no paid tier described, the main trade-off is not a feature ladder but the operational responsibility: teams provide and manage the server environment themselves.

The free plan is a strong fit for technically capable organizations that want control over an on-premise VDI deployment without a software charge. It is a weaker fit for teams that need a managed service or a personal support hotline; the project directs users to documentation, GitHub issues, a Google group and a public Telegram group, and its developers are unpaid volunteers.

Platforms

Ravada is listed for Linux, macOS, Windows, web and self-hosted use. The server runs on Linux distributions, with supported packages for Ubuntu, Debian and Fedora or installation through Docker. Users connect through a browser and a SPICE-compatible viewer; client setup documentation covers Linux and Windows, with macOS setup pages as well.

Who it's for

Ravada suits sysadmins building on-premise virtual desktops who are comfortable with basic GNU/Linux administration, KVM and SPICE client setup. SQL or LDAP authentication support may also make it a natural fit for organizations already using either. Teams seeking a managed, hands-off service, a different currently supported hypervisor, or direct personal support should look elsewhere.

Pros and cons

Pros

• No software charge: The free plan is billed Free to use, making it an accessible option for teams able to provide their own infrastructure.
• Useful administration surface: One web frontend covers user machine access and settings alongside pool and template management.
• Established authentication options: SQL and LDAP support can fit existing identity setups.
• Multiple Linux installation routes: Supported packages and Docker give administrators alternatives for deployment.

Cons

• Linux expertise is expected: Deployment is self-hosted and calls for Linux-based server administration.
• KVM is the current backend: Teams relying on another hypervisor cannot treat future extensibility as present support.
• Client setup takes more than a browser: Users also need a SPICE-compatible remote viewer.
• Community channels, not a support hotline: Help is directed through documentation and public community channels, with developers working as unpaid volunteers.

Alternatives

Compare virtual desktop infrastructure software if you want to survey the category before choosing a self-hosted broker.

• QVD is another free-plan option, with a developer-and-tester Community Edition and GitHub community support.
• ThinLinc is worth considering if you want a free tier capped at 10 concurrent users or a paid Standard plan priced per user per year.
• Hive Fabric may suit teams looking for a free perpetual community license for one physical host and unlimited VMs.
• Hydra offers a community edition with limited tenants and host pools, or a Windows 365 plan priced monthly.
• Kasm Workspaces has a free Community plan capped at five concurrent sessions and restricted to non-commercial use.
• Amazon WorkSpaces is a paid alternative with a Windows single-session user fee of $4.19 a month, plus provisioned instance-hour charges.
• Citrix Workspace is a paid alternative for readers comparing commercial workspace software.
• IsardVDI is another free, open-source VDI option.

Verdict

Choose Ravada if you want a free, self-hosted VDI broker, can administer Linux and KVM, and are prepared to support SPICE clients and the deployment yourself.
