VPN Unlimited, developed by KeepSolid and headquartered in the United States, is available across a range of platforms. This guide walks through the installation and basic setup process on each supported platform so you know what to expect before getting started.
Windows
Download the Windows client directly from the VPN Unlimited website (vpnunlimitedapp.com) or through the Microsoft Store. Run the installer and follow the on-screen prompts to complete installation. Once installed, open the app, sign in with your KeepSolid account, select a server location from the list, and click the connect button. The Windows client supports several protocols including WireGuard, OpenVPN, and IKEv2, which can be switched from within the settings menu.
Mac
The macOS app is available through the Mac App Store or as a direct download from the VPN Unlimited website. After installation, open the app and log in with your KeepSolid credentials. Server selection and protocol options work similarly to the Windows version. Note that macOS may prompt you to allow a VPN configuration profile — you will need to approve this in System Settings for the connection to function.
iOS
Install VPN Unlimited from the Apple App Store by searching for the app name. After downloading, open it and sign in. iOS will ask permission to add a VPN configuration to your device; tap Allow to proceed. The app interface on iOS is streamlined, offering server selection and a single connect toggle. Protocol options may be more limited on iOS compared to desktop versions due to Apple's platform restrictions.
Android
The Android app is available on the Google Play Store. Download and install it, then sign in with your KeepSolid account. The app will request permission to set up a VPN connection on your device, which you must grant. Android users generally have access to a wider range of protocol options than iOS users. The interface follows a similar layout to other mobile versions of the app.
Linux
VPN Unlimited does not offer a dedicated graphical Linux client. Linux users must configure the VPN manually using supported protocols such as OpenVPN, WireGuard, or IKEv2/IPSec. Configuration files and setup instructions are available through the KeepSolid user office (the account management portal). The process involves downloading the appropriate configuration files, installing the relevant protocol software on your Linux distribution, and importing or entering the configuration details manually. This makes Linux setup considerably more involved than on other platforms and requires a degree of comfort with the command line.
Amazon Fire Stick
VPN Unlimited can be installed on Fire Stick devices, though it is not always directly available in the Amazon Appstore depending on your region. One common method is to enable apps from unknown sources in Fire Stick settings and then use the Downloader app to sideload the Android APK from the VPN Unlimited website. Alternatively, if the app appears in your regional Amazon Appstore, it can be installed directly. Once installed, the experience mirrors the Android app. Performance on Fire Stick hardware may vary depending on the server and protocol selected.
Router
There is no dedicated router firmware from VPN Unlimited, but manual configuration is possible on routers that support OpenVPN or IKEv2. You will need to download the appropriate configuration files from the KeepSolid user office and enter them into your router's VPN client settings. This approach covers all devices on your network without needing individual app installations. Compatible router firmware includes options such as DD-WRT and Tomato, though setup complexity varies by router model. Router-level VPN connections may also reduce throughput compared to direct device connections.
Given VPN Unlimited's overall score of 52% in our testing, users should weigh the setup process against the service's broader performance characteristics before committing.
