RustDesk

RustDesk review

RustDesk is the only tool on this site with no licensing question attached. It is open source under AGPL-3.0, free for commercial use, and you can run the entire server side yourself so no third party ever handles your connections. If TeamViewer’s “commercial use suspected” message is what brought you here, this is the answer.

What RustDesk is

RustDesk is a remote desktop application written in Rust, with a Flutter interface across desktop and mobile. Functionally it behaves like the commercial tools: each installation gets an ID and a password, you enter them, you see and control the other screen.

The difference is structural. RustDesk is not a service with a free tier — it is software, published under the AGPL, and the infrastructure it talks to is software you can also run. There is no account required, no usage analysis, and nothing that decides your session looks too professional.

The current release is version 1.4.9. This matters more than usual: RustDesk moves quickly, and older builds are common on download aggregator sites. Get it from the project directly.

Free for commercial use, genuinely

This is the reason to pick RustDesk, so it is worth being precise. The client is AGPL-3.0. There is no personal-use clause, no session cap, no device limit and no detection heuristic. An IT consultancy can use RustDesk to support paying clients without buying anything.

Compare that with the alternatives:

There is a paid product, RustDesk Server Pro, but it is an optional commercial extension of the server for central management — a web console, user accounts, device groups, permissions. The client stays free regardless, and so does the open-source server.

Self-hosting, and why you might

RustDesk’s server side is two small components, both AGPL-3.0 and packaged together as RustDesk Server OSS:

• hbbs — the rendezvous and signalling server. It hands out IDs and helps two clients find each other.
• hbbr — the relay. It carries session traffic when a direct peer-to-peer connection cannot be established.

Both run comfortably on a very small Linux VM, and Docker images are published, so a working private deployment is a Docker Compose file and two open ports. Point your clients at your own host and every session runs on infrastructure you control.

For a business, this is the genuinely differentiating feature. It is not merely cheaper than TeamViewer — it removes an entire third party from the path between your technician and your customer’s desktop, which is an argument you can make to an auditor.

You can also use RustDesk’s free public servers and skip all of this. They work. They are shared, best-effort infrastructure with no service commitment behind them, which is fine for helping a relative and not a foundation for a support business.

Platforms

Windows, macOS and Linux are all fully supported in both directions — each can control and be controlled. Android and iOS clients exist, and there is a browser-based client too.

The mobile caveats are the same platform restrictions every vendor faces, and they are not RustDesk’s doing:

• iOS devices cannot be controlled remotely. Apple does not permit it, for any app. An iPhone can control other machines.
• Android needs an accessibility permission before a remote operator can send input, for the same reason AnyDesk needs a plugin.

Getting connected

1. Download the client for each machine from the official site or the project’s releases page.
2. Launch it. Each machine shows an ID and a one-time password.
3. Enter the other machine’s ID and the password it displays.
4. For repeat access, set a permanent password in the client’s settings rather than reading out the rotating one.
5. To use your own server, open Settings → Network and enter your hbbs host and key.

Where RustDesk falls short

• It is less polished. Rough edges in the interface, occasional regressions between releases. It is a fast-moving open-source project and it feels like one.
• Self-hosting is real work. Straightforward if you are comfortable with Docker and DNS; a genuine barrier if you are not.
• The public servers carry no guarantees. No SLA, no support desk, no promise of capacity.
• No enterprise support contract unless you buy Server Pro — which is exactly the trade for the price.
• Antivirus software sometimes flags it, as it does most remote access tools, because the behaviour is indistinguishable from what an attacker would want.

Security

Connections are end-to-end encrypted, and self-hosting removes the vendor from the trust equation entirely — a stronger position than any proprietary competitor can offer, since with a self-hosted relay there is no company whose breach could affect you.

The usual warning still stands, and applies to every tool here. Remote desktop software is the standard instrument of technical support scams. Never give your RustDesk ID and password to someone who contacted you first.

Who it is for

RustDesk is the right choice if you need free commercial use, if you want to self-host, if you work on Linux, or if you object on principle to a third party sitting in the middle of your remote sessions. It asks more of you than the commercial products and gives back control that none of them offer.

Pick something else if you want the smoothest possible experience with zero setup — AnyDesk is faster and more polished for personal use — or if you need a vendor with a support contract, which is TeamViewer’s territory.

Weighing it against the commercial options directly? RustDesk vs AnyDesk and RustDesk vs TeamViewer go through the trade-offs side by side.
