Quick Verdict
RustDesk is the better TeamViewer/AnyDesk replacement — it's a full remote desktop solution with native clients, file transfer, and direct peer-to-peer connections. Apache Guacamole is better as a remote access gateway — access RDP, VNC, and SSH sessions through a web browser without installing anything on the client side.
Overview
RustDesk is a self-hosted remote desktop application written in Rust. You run a relay/rendezvous server, install the RustDesk client on both machines, and get a TeamViewer-like experience with peer-to-peer connections, file transfer, and clipboard sharing. It replaces TeamViewer, AnyDesk, and similar commercial tools.
Apache Guacamole is a clientless remote desktop gateway. It runs as a web application and lets you access RDP, VNC, SSH, and Telnet sessions through your browser. No client installation needed — just a web browser. It's designed for centralized access to multiple remote machines.
Feature Comparison
| Feature | RustDesk | Apache Guacamole |
|---|---|---|
| Client required | Yes (native app) | No (browser-based) |
| Protocols | RustDesk protocol | RDP, VNC, SSH, Telnet, Kubernetes |
| File transfer | Yes (built-in) | Yes (SFTP, RDP drive) |
| Clipboard sharing | Yes | Yes |
| Audio forwarding | Yes | Yes (RDP) |
| Multi-monitor | Yes | Yes |
| Mobile client | Yes (iOS, Android) | Browser-based (works on mobile) |
| Unattended access | Yes | Yes (via RDP/VNC) |
| Session recording | No (OSS version) | Yes (built-in) |
| Connection management | Basic (address book) | Full (users, groups, connections) |
| Two-factor auth | No (OSS) | Yes (TOTP, Duo) |
| LDAP/SSO | No (OSS) | Yes (LDAP, OIDC, SAML) |
| Peer-to-peer | Yes (direct P2P with relay fallback) | No (all traffic through gateway) |
| Latency | Low (P2P) | Medium (gateway adds hop) |
| Wake-on-LAN | Yes | No |
| Language | Rust/Flutter | Java/C |
Installation Complexity
RustDesk Server requires two processes (hbbs for rendezvous, hbbr for relay) in a single Docker container using network_mode: host. Setup is quick — about 10 minutes. You then install the RustDesk client on each machine and configure it to use your server. See our RustDesk setup guide.
Apache Guacamole requires three containers: guacd (the connection daemon), the Guacamole web app, and a database (PostgreSQL or MySQL). You must manually initialize the database schema with SQL scripts. Setup takes 20-30 minutes. See our Guacamole setup guide.
Performance and Resource Usage
| Resource | RustDesk Server | Apache Guacamole |
|---|---|---|
| RAM (idle) | 30-50 MB | 200-400 MB |
| RAM (active session) | 50-100 MB | 300-600 MB per session |
| CPU | Low (relay only) | Medium-High (protocol transcoding) |
| Bandwidth | Low (P2P bypasses server) | All traffic flows through server |
| Disk | Minimal | Moderate (session recordings) |
RustDesk's server is lightweight because it primarily handles connection establishment — actual screen data flows peer-to-peer when possible. Guacamole processes all remote desktop traffic through the server, so it scales linearly with concurrent sessions.
Community and Support
RustDesk: Active open-source project with 82k+ GitHub stars. Regular releases (v1.1.15 as of January 2026). Strong community, active development. Note: some advanced features (2FA, LDAP, address book sync) require the Pro version.
Apache Guacamole: Apache Software Foundation project. Stable and mature (v1.6.0 as of June 2025). Enterprise-grade reliability. Slower release cadence but very stable. Extensive documentation.
Use Cases
Choose RustDesk If...
- You need a TeamViewer/AnyDesk replacement with native clients
- Low latency matters (peer-to-peer connections)
- You want to support friends/family remotely (give them the client, connect via ID)
- You need mobile remote access with a native app
- File transfer between machines is important
- You want minimal server resource usage
Choose Guacamole If...
- You need browser-based access (no client installation)
- You manage multiple servers/machines from a central dashboard
- You need to access RDP, VNC, and SSH from one interface
- Session recording for auditing is required
- You need LDAP/SSO integration for team access
- You want to give users access to specific machines without VPN
Can You Run Both?
Yes, and it makes sense in many setups. Use Guacamole as a centralized gateway for your server infrastructure (SSH, RDP to servers), and RustDesk for remote desktop support of user machines (laptops, desktops).
Final Verdict
RustDesk for remote desktop support. Guacamole for infrastructure access.
If you're replacing TeamViewer or AnyDesk for remote support — helping family, accessing your own machines, or providing IT support — RustDesk is the direct replacement. Native clients, peer-to-peer performance, and a familiar remote desktop experience.
If you manage multiple servers and want browser-based access to RDP, VNC, and SSH sessions from anywhere — Guacamole is purpose-built for this. No client installation, centralized connection management, and session recording.
FAQ
Can Guacamole replace RustDesk for remote desktop support?
Partially. Guacamole can connect to machines running VNC or RDP, but it requires those protocols to be pre-configured on the target machine. RustDesk handles the full workflow: install client → get ID → connect. Guacamole assumes the target is already set up for remote access.
Does RustDesk work without the self-hosted server?
Yes, but with limitations. RustDesk has public relay servers, but they may be slow or unavailable. Self-hosting the server gives you reliable connectivity and keeps traffic off public infrastructure.
Can I use Guacamole on mobile?
Yes — it's browser-based, so it works on any device with a modern web browser. The experience on small screens varies by protocol (SSH works well, RDP is usable, VNC depends on resolution).
Which is more secure?
Both can be secured properly. RustDesk encrypts all connections with Ed25519 keys. Guacamole supports 2FA, LDAP, and session recording. Guacamole has the edge for enterprise security requirements; RustDesk is simpler to secure for personal use.
Does RustDesk support Linux?
Yes. RustDesk has native clients for Windows, macOS, Linux, Android, and iOS. The Linux client supports both X11 and Wayland.
