RustDesk is an open-source remote-desktop application that has rapidly become the go-to free alternative to TeamViewer and AnyDesk. Its headline is that it's genuinely free and, crucially, you can self-host the relay server — meaning your remote sessions never have to touch a third party's infrastructure. For privacy-conscious users, tinkerers and budget-bound technicians, it's a compelling package; in return you accept a less polished experience and DIY support.
Our verdict
RustDesk is the standout free, open-source remote-desktop tool: self-hosting gives you a level of control and privacy no commercial rival offers for free, and the core features cover most real-world needs. You trade polish and guaranteed support for that freedom, so it suits technically confident users more than businesses wanting a hands-off product — but for the right person it's exceptional value.

Features & capability
RustDesk covers the core of remote desktop well: attended and unattended access, file transfer, cross-platform clients including mobile, and clipboard sync. It won't match the breadth of TeamViewer, but for connecting to a machine and getting work done it's more than capable. The defining feature is the option to run your own relay (and ID) server, so no session data flows through anyone else's servers — something no mainstream commercial tool offers for free.
Security
Sessions are end-to-end encrypted, and self-hosting lets you keep everything in-house, which is a genuine privacy advantage. The flip side: when you self-host, you are responsible for securing, patching and updating that server — get it wrong and you've created a risk rather than removed one. As with any remote tool, enforce strong credentials and never grant access to an unsolicited contact; see our security guide.
Pricing & value
RustDesk is free and open-source. There are paid self-hosting plans and Pro options for teams that want extras without running everything themselves, but the core is free. For value, nothing else on our list competes — provided you can live with community support and a bit of setup. Compare it against the free tiers in our best free remote desktop guide.
Who should use RustDesk?
Best for
Privacy-conscious users, home-labbers, developers and budget-bound technicians who want a free, self-hostable remote-desktop tool and don't mind a DIY approach.
Not ideal for
Businesses needing guaranteed vendor support, polished enterprise management, or a zero-setup experience — a commercial tool will be less hassle.
Frequently asked questions
Is RustDesk really free?
Yes — RustDesk is free and open-source. You can use the public servers or self-host your own. There are optional paid plans for teams that want managed hosting and Pro features.
Can I self-host RustDesk?
Yes, and it's the main draw: you can run your own relay and ID server so remote sessions never pass through a third party. It requires some technical setup and ongoing maintenance.
Is RustDesk safe to use?
Sessions are end-to-end encrypted and self-hosting keeps data in-house. Being open-source, the code is auditable. If you self-host, you're responsible for securing and patching that server.
Is RustDesk a good TeamViewer alternative?
For many users, yes — it's free, cross-platform and self-hostable. It's less polished and lacks enterprise support, so weigh convenience against cost and control. See our TeamViewer alternatives guide.
