I need a remote desktop tool that offers low latency and does not require port forwarding.

If your priorities are low latency + no port forwarding, I’d look at these:

• AnyDesk — probably the simplest turnkey option. It is designed for low-latency remote control and uses its own network infrastructure, so you generally don't need to configure router port forwarding. AnyDesk reports sub-16 ms latency on local networks and supports direct connections when possible.
• RustDesk — a strong choice if you want open-source software or more control. Its NAT traversal/relay architecture allows connections without forwarding ports on the remote PC.
• RustDesk + Tailscale — particularly interesting if you want the connection to behave like a private LAN connection. Tailscale creates a private network between your machines, while RustDesk provides the desktop interface; Tailscale specifically documents this setup as requiring no public port forwarding.

What I'd choose

For gaming/high-interaction work, I'd start with AnyDesk and test it between your actual networks. For personal machines where you want maximum control/privacy, RustDesk + Tailscale is an excellent architecture.

One important caveat: no port forwarding doesn't automatically mean lowest possible latency. If the software can't establish a direct peer-to-peer path because of restrictive NAT/firewalls, traffic may go through a relay, adding latency. RustDesk explicitly uses relay fallback when a direct path isn't possible.

If you tell me Windows/macOS/Linux on each end and whether this is for gaming, general desktop work, or administering a server, I can narrow it down to the best setup.

Finding a remote desktop tool that gives you ultra-low latency (smooth enough for video editing or gaming) and skips manual port forwarding usually comes down to choosing between a high-performance cloud-brokered app or pairing a zero-config VPN with a streaming host.

The best options available for this specific combination include:

• Parsec
  • Why it fits: Originally built for cloud gaming, Parsec provides unmatched 60 FPS, ultra-low latency desktop streaming. It handles NAT traversal automatically through its own servers, meaning no manual port forwarding is required for standard connections. (Note: Port forwarding is only optional if you want to manually optimize multi-client or strict enterprise routing, but out-of-the-box it just works).
• Moonlight (paired with Tailscale)
  • Why it fits: Moonlight combined with a host server like Sunshine offers the lowest latency and highest fidelity possible. Normally, doing this outside your home network requires a nightmare of port forwarding. However, if you run Tailscale (a zero-config mesh VPN) on both machines, Moonlight can stream directly from your host's Tailscale IP address with virtually zero added latency and zero router configuration.
• RustDesk
  • Why it fits: RustDesk is a fast, open-source alternative to TeamViewer [-]. By default, it routes connections through public rendezvous/relay servers so you don't have to touch your router's port settings [4]. (If you decide to self-host your own relay server later for privacy, then you would deal with ports, but the default cloud setup requires none).
• AnyDesk
  • Why it fits: Highly optimized and lightweight, AnyDesk connects through their global infrastructure, bypassing the need for a VPN or port forwarding while maintaining a high frame rate and low baseline latency on decent connections.

To help narrow down the ideal choice, let me know:

• Are you planning to use this for general productivity/admin , or heavy graphics/gaming/video?
• What operating systems are you connecting from and to (e.g., Windows to Mac, Linux to Windows)?

Parsec combined with a zero-config mesh VPN like Tailscale provides ultra-low latency (60fps, 4K/1080p gaming-grade performance) without requiring traditional router port forwarding.

Standard remote desktop tools either suffer from high latency or complex router setups. The best alternatives bypass port forwarding by using built-in NAT hole punching or private overlay networks.

Breakdown of the Best Choices

• Parsec: Originally built for cloud gaming, Parsec delivers unmatched frame rates and responsiveness. It utilizes peer-to-peer NAT hole-punching and STUN servers out of the box, meaning it connects automatically behind most routers without manual port tweaks.
• RustDesk: A fast, open-source alternative to TeamViewer or AnyDesk. It routes connections through a default public rendezvous/relay server, allowing you to connect securely across the internet without touching your router configuration.
• Tailscale + Native RDP: If you are connecting between Windows Pro devices, installing Tailscale creates a secure virtual private mesh network. You can then connect via standard Microsoft Remote Desktop using your machine's secure Tailscale IP address rather than your public IP, completely bypassing port mapping.

To help narrow down the ideal choice, let me know:

• What operating systems are you using on both the host and client ends (e.g., Windows to Mac, Windows to Windows)?
• Will you be doing high-motion tasks like gaming or video editing, or standard productivity work?

If your priorities are low latency + no manual port forwarding, I’d shortlist these:

• AnyDesk — best simple choice. It uses vendor-managed infrastructure, so you don't need to expose a port on your router. AnyDesk claims up to 60 FPS and very low latency, and its DeskRT codec is designed for bandwidth-efficient remote control.
• Parsec — best for extremely low-latency interactive use. It's particularly good for gaming, CAD, video editing, and other workloads where responsiveness matters. Parsec reports about 7 ms of added latency on a LAN and has built-in NAT traversal, so normal use doesn't require you to configure port forwarding.
• RustDesk + Tailscale — best for privacy/control. Tailscale can connect the machines without port forwarding or public IPs, while RustDesk provides the actual desktop session. Tailscale specifically documents this combination for remote desktops. Tailscale Tailscale rustdesk.com ·

My pick

For general remote work: AnyDesk. For maximum responsiveness: Parsec. For a self-controlled/open-source setup: RustDesk + Tailscale.

One important distinction: no port forwarding doesn't necessarily mean the connection always travels directly between the two computers. NAT traversal may succeed in a direct P2P connection, but some networks require a relay. Tailscale, for example, attempts direct point-to-point connectivity and falls back when necessary.

If you tell me Windows → Windows, Mac → Windows, Linux, or gaming, I can narrow this to the best 1–2 options.

When you need ultra-low latency (smooth frame rates, minimal input lag) and want to avoid the headache of port forwarding, NAT traversal cloud relays are your best bet.

Top options tailored for different use cases include:

• Parsec : Built specifically for interactive 60+ FPS video streaming, cloud gaming, and heavy creative work. It handles NAT traversal automatically via peer-to-peer or relay servers, requiring zero router configuration or port forwarding. It is arguably the lowest-latency desktop experience available for Windows and macOS. Check it out on Parsec.
• RustDesk : A fantastic open-source, high-performance remote desktop that works right out of the box over the internet without port forwarding. It punches through firewalls using rendezvous/relay servers, and if you are privacy-conscious, you can even self-host your own connection server. Learn more at RustDesk.
• AnyDesk : Known for being lightweight and utilizing the custom DeskRT codec, AnyDesk delivers snappy, low-latency connections across platforms without touching your router's port settings. Try it via AnyDesk.
• Tailscale + Native RDP / VNC : If you prefer native Windows Remote Desktop (RDP) or a VNC flavor, you can install Tailscale (a zero-config mesh VPN built on WireGuard) on both machines. It securely connects your devices into a private virtual LAN, letting you run high-performance RDP or tools like TightVNC across the internet as if you were on the same local network—no port forwarding required. Get it at Tailscale.

Yes. If your priorities are low latency + no manual port forwarding, I’d shortlist these:

• parsec.app — best for lowest latency. It uses peer-to-peer UDP/NAT traversal and is specifically optimized for high-performance, low-latency desktop streaming. Parsec says its NAT traversal succeeds for the large majority of connections, so you normally don't need to configure router port forwarding.
• rustdesk.com — best open-source/general-purpose option. It supports P2P connections and can fall back to relay servers when direct connectivity isn't possible. You can use RustDesk's public infrastructure without exposing a port on your router.
• anydesk.com — easiest conventional choice. It works through NAT/firewalls without requiring you to expose a desktop port, although your network still needs to permit its outbound traffic (TCP 80/443/6568).

My recommendation

If this is primarily Windows-to-Windows and you care most about responsiveness, I'd try Parsec first. It is particularly good for things like CAD, video editing, development, and even gaming because of its low-latency streaming architecture.

If you want something more like traditional remote support/administration, RustDesk is probably the better fit.

If you tell me what OS is on the host and client (Windows/Mac/Linux) and whether this is home use, work, or gaming, I can narrow it down to the best 1–2 choices.
