Free Alternative to TeamViewer/AnyDesk

I tested version 1.2.3. The UI looks suspiciously like TeamViewer. This is entirely intentional. It gives you a numerical ID and a one-time password. You share those credentials, and the other person connects. I found the public relay servers to be surprisingly fast. I experienced about 50 milliseconds of latency when connecting from New York to Chicago. The true power of RustDesk is self-hosting. You can spin up your own relay server using Docker in about ten minutes. This bypasses their public servers completely. The macOS client handles file transfers natively. I did notice the clipboard sync occasionally stops working if you switch between text and images too quickly. It is written in Rust. It barely touches your CPU during idle periods.

Google built a remote access tool directly into Chrome. You install a host package on the Mac. You then access it through a web portal from any other machine. It feels strange to control a whole desktop from inside a browser tab. The performance holds up well for basic tasks. I used it to sort through a massive folder of RAW photos. The image quality degrades slightly when you scroll fast to save bandwidth. It tops out at 30 frames per second. You will not want to edit video over this connection. The biggest advantage is the total lack of firewall configuration. If you can load a webpage, you can connect. I hate that it forces you to use a Google account for authentication.

This is my personal favorite method. Tailscale is a zero-config VPN built on WireGuard. It assigns a static IP address to every device you own. You install it on your Mac. You install it on your laptop. They can now talk to each other securely over the internet. You just open the native macOS Screen Sharing app and type in the Tailscale IP address. Apple built their VNC client into the operating system years ago. It performs beautifully. I use this to manage my headless Plex server. The connection never drops. The obvious limitation is that you have to install Tailscale on both ends. This makes it terrible for one-off tech support with strangers. For accessing your own machines, it beats any paid software on the market.

NoMachine uses a proprietary protocol called NX. It was designed specifically for high-performance video and audio streaming. I tested version 8.11 on my M3 Mac. I was actually able to play a low-resolution indie game remotely. The frame rate hovered around 60fps over my local network. The interface feels dated. It looks like a holdover from 2015. The configuration menus are dense with network terminology that will confuse average users. It also struggles with remote access outside your home network unless you know how to forward ports on your router. If you need to access a Mac on the same Wi-Fi network with zero lag, this is the absolute best option.

This is a relatively new fork of RustDesk. The developers took the open-source code and added end-to-end encryption by default for all connections. I installed it via Homebrew. The setup process is identical to its parent project. You get an ID and a password. The network traffic routes through their own global privacy network. I found the connection speeds to be slightly slower than plain RustDesk during peak hours. I waited a full two seconds for a window drag to register on one occasion. The security model is appealing. They promise never to track IP addresses or collect metadata. The Mac client feels native enough. It does prompt you aggressively to enable Accessibility permissions upon first launch.

DWService takes a completely different approach to remote access. You install a tiny Node.js agent on the host Mac. You then log into their website to control the machine. The screen sharing happens entirely within an HTML5 canvas element. I expected this to be horribly slow. I was wrong. The latency is manageable for basic file management and system updates. The web dashboard gives you direct access to the Mac terminal and file system without even loading the graphical interface. I used the remote shell to run Homebrew updates on a machine in another room. The screen scaling can get weird if you are connecting from a small laptop to a 4K iMac. It is entirely free and funded by donations.

VNC is an ancient protocol. TigerVNC is one of the few actively maintained clients that still works well on modern macOS builds. I installed the viewer to connect to a Linux box. I also tested it Mac-to-Mac. It strips away all the modern conveniences. There are no relay servers. There is no NAT traversal. You need a direct IP connection to the host machine. The tradeoff is absolute control. You can tweak the JPEG compression ratio manually. You can force the connection to use specific color depths. I dropped the color depth to 8-bit to check an email over a terrible hotel Wi-Fi connection. The screen looked awful. The mouse moved instantly. This is strictly for network administrators and power users.

Splashtop is a massive commercial enterprise now. They still offer a free personal tier for local network use. I installed the streamer app on my Mac mini. I put the client on my MacBook. The video rendering is incredible. They use hardware acceleration to encode the screen capture. I watched a 1080p YouTube video through the remote connection with perfect audio sync. The catch is the artificial paywall. The moment you leave your house, the app refuses to connect. You have to pay a monthly fee for the Anywhere Access pack. It also forces you to create a cloud account just to connect to a machine sitting three feet away. I tolerate it only because the local performance is so good.

RealVNC created the original VNC protocol. They offer a free viewer application that is highly polished. The interface is clean. It saves your connection history with nice little screenshot thumbnails. I use it strictly as a client to connect to machines running the native Apple screen sharing server. The scrolling feels smoother than Apple's built-in app. It handles international keyboard layouts perfectly. I never get weird character outputs when typing passwords. They recently killed off their free server tier for home users. You cannot use this to host a session for free anymore over the internet. It remains an excellent, lightweight viewer app to keep in your dock.

Guacamole is an enterprise-grade clientless remote desktop gateway. I installed it using Docker on a home server. It bridges the gap between your web browser and the VNC server running on your Mac. You do not install a client app. You just go to a local URL. You log in. Your Mac desktop appears in the browser. I set this up for a client who wanted access to their office iMac without installing software on their personal laptop. The initial setup is brutal. You have to configure Tomcat and the guacd daemon. Once it is running, it never breaks. It supports two-factor authentication natively. I would never recommend this to a casual user.
