Raspberry Pi Remote Access: Easy, Free Solutions & Tips!

Are you tired of being tethered to your Raspberry Pi, wishing you could tinker with your projects from anywhere? The ability to remotely access and control your Raspberry Pi is no longer a futuristic dream but a readily achievable reality.

The modern digital landscape demands flexibility, and the Raspberry Pi, with its compact power, has become a cornerstone for hobbyists, educators, and professionals alike. Yet, its full potential is often limited by the need for direct physical access. Imagine the freedom of accessing your home automation system, debugging a robotics project, or managing a server, all from the comfort of your couch or while on the move. This is where remote access solutions step in, transforming your Raspberry Pi from a stationary device into a versatile, accessible tool.

Remote access to your Raspberry Pi can be achieved through various methods, each with its own set of pros and cons. The core principle remains the same: establishing a secure connection to your device, allowing you to interact with its desktop environment and command line interface. This capability opens up a world of possibilities, from monitoring and controlling IoT devices to providing remote technical support. Several paths lead to this goal, each with its own characteristics in terms of security, ease of use, and cost. Lets delve into some of the prominent solutions available, keeping in mind that the best choice often depends on your specific needs and technical expertise.

One of the most straightforward approaches involves utilizing VNC (Virtual Network Computing). This technology essentially allows you to view and control your Raspberry Pi's desktop from another device. To implement VNC, you can either expose SSH or VNC directly over the internet, set up a Virtual Private Network (VPN), or leverage external services such as RealVNC's cloud VNC viewer. Setting up a VPN provides an additional layer of security by encrypting the communication between your device and the Raspberry Pi. Services like RealVNC offer a user-friendly interface and often simplify the setup process by handling the complexities of network configurations.

Another option is Raspberry Pi Connect, a free screen-sharing and remote shell service developed by the Raspberry Pi Foundation. Announced with great fanfare, this service aims to simplify remote access for individual users, offering a secure and accessible platform directly on Raspberry Pi devices. The goal is to make remote access as user-friendly and efficient as possible. Raspberry Pi Connect has gone through beta releases, indicating active development and improvement. It is designed to remove the technical hurdles that often accompany remote access setup.

For those seeking a free software alternative, Nomachine is a viable option. Similar to popular remote desktop tools like TeamViewer and AnyDesk, Nomachine allows you to share your Raspberry Pi's desktop and enable remote interaction. It is known for its performance and ease of setup, making it a solid choice for various remote access needs. The user-friendly interface makes the process intuitive for both beginners and experienced users.


Twingate emerges as a secure, hassle-free remote access solution, specifically designed to eliminate the need for VPN configurations, port forwarding, static IP addresses, or Dynamic DNS (DDNS) setup. The simplicity of Twingate is a major draw, making it a strong choice for users who want to avoid the complexities that often accompany remote access setup. Twingate's focus on ease of use, combined with robust security features, presents a compelling option for Raspberry Pi users.

Other tools, such as TeamViewer, AnyDesk, and Chrome Remote Desktop, offer their own strengths in terms of remote access. These established solutions are known for their ease of use and cross-platform compatibility, making them accessible from almost any device. While some of these solutions may require initial configuration, their widespread availability and feature sets make them attractive options for various remote access requirements.

One of the key benefits of utilizing remote desktop software is the ability to access and control your Raspberry Pi from anywhere in the world, provided you have an internet connection. This is particularly valuable if you're working on projects that require constant monitoring or interaction but don't need to be physically present. This is essential in scenarios such as managing a home automation system, overseeing industrial applications, or assisting clients with remote technical support.

RealVNC server is a free to use on the Raspberry Pi, allowing you to view and control your Raspberry Pi from any device with the viewer app installed. The viewer is free, and by creating a free account, you can access up to five devices remotely. This makes RealVNC a cost-effective solution for those needing to manage multiple Raspberry Pi devices.

Another critical use case is remote access to IoT devices. With remote access solutions, you can manage and monitor IoT devices, set up cloud alerts, and run batch jobs from a remote location. This capability is crucial in industrial and embedded applications, where continuous monitoring and control are paramount.

When you opt for solutions like RealVNC, remember that your customer's network has WiFi. Your Raspberry Pi can connect to the internet via WiFi. On the Raspberry Pi, a webserver (HMI) will run so your customer can view/control the PLC which is connected directly to the Pi, thus allowing you to remotely support your customers.

When selecting a remote access solution, remember the importance of security. While services like Raspberry Pi Connect and Twingate aim to simplify the process, its essential to understand the security implications. Always choose solutions that encrypt data and provide strong authentication mechanisms to protect your device and network. Carefully assess the requirements of your project, the level of technical expertise, and the need for ease of use to determine which solution best fits your needs. Don't take any chances with your network security. It's always better to be safe than sorry.
