RustDesk vs TeamViewer: which should you use?

If your use is work-related and the budget is zero, pick RustDesk. If you need a polished commercial support platform and can pay for it, pick TeamViewer. Everything else in this comparison is details around that fork.

Quick comparison

	RustDesk	TeamViewer
Free for commercial use?	Yes — unrestricted (open source)	No — personal use only
Free-tier enforcement	No commercial-use detection	Aggressive; sessions can drop after ~5 minutes with “commercial use suspected”
Self-host	Yes (open-source `hbbs`/`hbbr`, optional Server Pro)	No equivalent free on-prem path
Setup effort	Higher if you self-host; public servers work with less work	Lower — install, connect
Best fit	No-budget work support, Linux fleets, privacy-minded self-host	Paid support desks that need breadth and vendor support
Weak spot	Less polish; public servers have no SLA	Cost; false positives on free licence

The licensing difference that actually matters

TeamViewer’s free version is for personal use: helping family and friends, or reaching your own non-commercial devices. TeamViewer’s own documentation defines commercial use broadly — supporting customers or colleagues, home-office access to a work PC, server administration, and many non-profit cases where people are paid. When usage looks commercial, TeamViewer flags IDs and sessions start failing with “commercial use suspected” (often after roughly five minutes). Reinstalling does not clear it; you submit IDs through TeamViewer’s reset process, and review can take days.

RustDesk does not have that clause. The client is AGPL-3.0, free for commercial use, with no personal-use-only free tier. Optional paid product is RustDesk Server Pro for central management — not a tax on every work session. That is why people who hit TeamViewer’s detector usually land here.

Features and day-to-day use

TeamViewer wins on breadth when you pay: file transfer, session recording, remote printing, address book, wake-on-LAN, multi-monitor handling, and tooling aimed at managed fleets. For a real support desk with budget, that still matters.

RustDesk covers the core job — ID/password connect, control, file transfer, clipboard, unattended password — across Windows, macOS, and Linux (and mobile clients exist). It is less polished. Expect occasional rough edges between releases. Current release noted on this site’s review at research time: 1.4.9 — always download from the project, not random mirrors.

Self-hosting

RustDesk’s structural advantage is infrastructure you can own. Server OSS is two components:

hbbs — ID / rendezvous
hbbr — relay when peer-to-peer fails

Docker deployments are documented; point clients at your host and third-party relay drops out of the path. Public RustDesk servers also work, with no SLA — fine for family help, weak foundation for a paid support business.

TeamViewer does not offer a free self-hosted equivalent. If on-premises is a hard requirement and you want a supported commercial product instead of DIY, look at ISL Online rather than stretching free TeamViewer.

Platforms and caveats (both tools)

Same platform limits apply industry-wide:

You cannot remotely *control* an iPhone or iPad — view only. See AnyDesk for iPhone for the plain explanation.
Android control usually needs an extra accessibility / plugin step.
Mac incoming sessions need Screen Recording and Accessibility permissions or you get a black screen — same class of problem covered on AnyDesk for Mac.

On Linux, RustDesk is often the stronger free choice: native builds both ways. TeamViewer still works widely when licensed.

Recommendation by scenario

Clients or colleagues, no budget: RustDesk. Self-host if sessions must not ride shared public infrastructure.
Family / friends: Either works on free personal use. Many people prefer AnyDesk for speed on poor connections; TeamViewer is fine until detection misfires.
Paid support desk: TeamViewer if you want the most capable commercial platform. ISL Online if you need self-host or pay-per-minute. LogMeIn for multi-tech queues and enterprise auth — and the budget that implies.
Many machines, small paid budget: Iperius Remote (concurrent connections, not per device) is often cheaper than TeamViewer entry plans.
Two machines permanently, commercial OK free: Getscreen.me.

FAQ

Is RustDesk free for commercial use?

Yes. Open source under AGPL-3.0 with no personal-use-only free tier. Server Pro is optional paid management, not a requirement to support clients.

Why does TeamViewer say commercial use suspected?

Free TeamViewer is personal-use only. Heuristics flag work-like patterns. Sessions then drop; reset goes through TeamViewer’s form, not a reinstall.

Can RustDesk replace TeamViewer for a help desk?

For basic remote control and free commercial use, yes. For session queues, reporting, vendor support contracts, and deep managed-device tooling, paid TeamViewer (or ISL Online / LogMeIn) is still the more complete desk product.

Do I need to self-host RustDesk?

No. Public servers work. Self-host if you want control, reliability you own, or to keep traffic off shared infrastructure.

Which is better for helping family?

Either on a free personal licence. If install friction matters, AeroAdmin (2 MB, no install, no account, Windows) is often easier for the person being helped.
