Why Consider TeamViewer Alternatives?
TeamViewer offers excellent features, but several factors make alternatives worth considering:
Cost Constraints
TeamViewer’s commercial licensing model can be expensive for organizations. The company strictly enforces its licensing terms and frequently flags accounts suspected of commercial use under free licenses. This detection system sometimes incorrectly flags legitimate personal use, causing interruptions in service.
Connection Limitations
The free version of TeamViewer imposes strict limitations on the number of devices and connections. These restrictions often prove insufficient for environments with multiple systems to manage.
Commercial Use Restrictions
TeamViewer’s free version is limited to personal use only. Organizations using the free version for business purposes face sudden disconnections and eventual blocking of their accounts.
Security Concerns
In recent years, TeamViewer has experienced security incidents that have raised concerns among IT professionals. In 2019, TeamViewer confirmed an intrusion into its systems, and users have reported unauthorized access attempts to their computers through the software.
Version Control Issues
TeamViewer often requires users to run the same version on both ends of the connection. This requirement creates complications in environments where version control is strictly managed.

Top 5 Free TeamViewer Alternatives
1. AnyDesk
AnyDesk has gained popularity as a lightweight yet powerful remote control solution. The software uses a proprietary codec called DeskRT, which provides fast performance even on connections with limited bandwidth.
Key Features
- Custom Client Branding: Customize the client with your company logo in the free version
- Session Recording: Record remote sessions for documentation or training purposes
- File Transfer: Transfer files between machines without interrupting the remote session
- Address Book: Save frequently accessed computers for quick connections
- Custom Aliases: Create custom addresses for easier connection to remote machines
- Multi-Platform Support: Windows, macOS, Linux, Android, iOS, FreeBSD, and Raspberry Pi
- Unattended Access: Connect to machines without someone present on the other end
Security Implementation
AnyDesk uses TLS 1.2 encryption and RSA 2048 asymmetric key exchange to secure all connections. Each device receives a unique ID, and you can set additional passwords for unattended access. The banking-standard security architecture protects against man-in-the-middle attacks.
Enterprise Deployment
The free version allows for personal use with basic features. While not explicitly blocking commercial use like TeamViewer, AnyDesk offers paid versions with additional features for enterprises:
- Directory service integration
- Central management console
- Policy management
- Advanced access control
Performance
AnyDesk excels in performance tests, particularly in low-bandwidth environments. The software requires minimal system resources with a small installation file (3MB) and low CPU usage during sessions. It performs well across varied connection speeds, maintaining usable remote control down to 100 Kbps.
Limitations
- Free version lacks some administrative features
- Custom permissions require the paid version
- No built-in scheduler for maintenance tasks
2. Chrome Remote Desktop
Google’s free remote access solution offers simplicity and security for basic remote control needs. It works through the Chrome browser or as a standalone application, making it accessible across multiple platforms.
Key Features
- Google Account Integration: Secure access using existing Google accounts
- Simple Setup: Easy configuration process with minimal technical knowledge required
- Cross-Platform Compatibility: Works on Windows, macOS, Linux, Android, and iOS
- Automatic Connection: Reconnects automatically if the connection drops
- Multiple Monitor Support: Navigate between multiple displays easily
Technical Architecture
Chrome Remote Desktop uses the Chromoting protocol, which operates over XMPP for the initial handshake and WebRTC for the actual remote session. The connection uses SSL/TLS encryption and is facilitated through Google’s infrastructure, which helps bypass many firewall issues.
Enterprise Limitations
As a consumer-focused solution, Chrome Remote Desktop lacks several enterprise features:
- No centralized management console
- Limited user permission controls
- No integration with Active Directory
- No session auditing or reporting capabilities
Security Framework
The solution leverages Google’s security infrastructure. Each connection requires a PIN code that’s generated for each session, and all data is encrypted during transit. Authentication is tied to Google accounts, which allows for two-factor authentication.
Chrome Remote Desktop works well for smaller teams and basic support scenarios but lacks the administrative features needed for large enterprise deployments.
3. RustDesk (Open Source Option)
RustDesk represents the next generation of open-source remote desktop software. Written in the Rust programming language for security and performance, it offers both self-hosted and public relay server options.
Self-Hosted Architecture
RustDesk consists of three main components:
- RustDesk Client: The application for connecting to remote machines
- RustDesk Server: The ID/rendezvous server that facilitates connections
- RustDesk Relay: Relays traffic when direct connections aren’t possible
System administrators can deploy these components within their network infrastructure for complete control over data flow and security.
Key Features
- Full Source Code Access: Review and modify the code to meet specific requirements
- No Installation Required: Can run as a portable application
- File Transfer: Bidirectional file sharing capabilities
- Cross-Platform Support: Windows, macOS, Linux, Android, iOS
- Multi-Session Support: Connect to multiple machines simultaneously
- Clipboard Synchronization: Share clipboard contents between local and remote systems
- Terminal Access: Direct command-line interface to remote systems
Security Analysis
The self-hosted option provides enhanced security as all data remains within your network perimeter. RustDesk uses TLS for encryption and offers additional features like blank screen during remote control and permission-based access controls.
Enterprise Considerations
RustDesk’s open-source nature makes it highly adaptable for enterprise environments:
- Customizable to specific security requirements
- Scalable based on organizational needs
- No costs for adding additional seats
- Complete control over the server infrastructure
The primary limitation is the need for technical expertise to set up and maintain the server components, making this option better suited for organizations with dedicated IT resources.
