Top Recommended Replacements
RustDesk
FREEBest Direct Replacement
Why we like it
The 2025 favorite for unbundling TeamViewer; written in Rust for incredible speed; supports self-hosted relay servers so your data never touches third-party servers; includes end-to-end encryption and custom branding (Pro).
Keep in mind
Requires manual setup of an ID server for maximum performance outside of local networks.
MeshCentral
FREEBest for IT Management
Why we like it
A full-featured web-based remote management console; handles thousands of devices from a single dashboard; supports Intel AMT for hardware-level control (even when the OS is crashed); completely free.
Keep in mind
The UI is technical and built for admins, not casual users; setup requires server-side expertise.
Tactical RMM
FREEBest for MSPs
Why we like it
A full Remote Monitoring and Management (RMM) suite built on top of MeshCentral; adds automation, patching, and script execution to remote access; completely open-source.
Keep in mind
Steep learning curve; requires a dedicated server to host the management backend.
HelpWire
FREEBest for Client Support
Why we like it
Specifically designed to disrupt the paid support market; 100% free for commercial use; features high-speed connections and an incredibly simple 'One-Click' client for customers.
Keep in mind
Cloud-only; no 'On-Premises' option for high-security environments.
Remotely (Tactical RMM Fork)
FREEBest Lightweight Option
Why we like it
Extremely fast web-based remote desktop; handles file transfers and multiple monitors well; works entirely through the browser.
Keep in mind
Smaller community support compared to RustDesk; development can be sporadic.
UltraVNC
FREEBest for Legacy Systems
Why we like it
The most battle-tested VNC flavor; includes a 'Single Click' (SC) module that allows clients to connect back to you without installing anything; extremely lightweight.
Keep in mind
VNC protocol is inherently slower than modern proprietary codecs over low-bandwidth connections.
Apache Guacamole
FREEBest Clientless Gateway
Why we like it
A clientless remote desktop gateway; use RDP/VNC/SSH from any browser with zero local software; perfect for giving contractors access without VPNs.
Keep in mind
Performance is limited by browser rendering; complex to configure initially.
Sunshine + Moonlight
FREEBest for High-Performance/GPU
Why we like it
The gold standard for low-latency streaming in 2025; allows for 4K/60fps remote work with zero lag; zero cost; ideal for remote video editors or designers.
Keep in mind
Requires a bit of network knowledge (Port Forwarding/Tailscale) to access over the internet.
NoMachine
FREEBest for Multimedia/Mac
Why we like it
Highest quality audio and video streaming among free-tier apps; very stable on macOS; highly efficient NX protocol.
Keep in mind
Enterprise features for massive deployments require a paid license.
HopToDesk
FREEBest for Ease of Use
Why we like it
A fork of RustDesk optimized for simplicity; 100% free for commercial use; no session limits or nag screens; works behind NAT automatically.
Keep in mind
Lacks the deep management 'Policy' controls of TeamViewer Tensor.
DWService
FREEBest Browser-Only Access
Why we like it
100% web-based; access your host from any device with a browser; includes built-in file manager and shell access; supported by community donations.
Keep in mind
Slightly higher latency than native applications.
