Mysterium VPN Goes Open Source With v2.4.8, Adding OpenVPN Support for Android

The Mysterium VPN team is thrilled to announce that our app code is now open source, making the app's repository public for anyone to inspect, run, and contribute to. The first result of this move is already live: Mysterium VPN v2.4.8 introduces OpenVPN support for Android, giving users an additional way to stay connected when a network restricts or interferes with the WireGuard protocol.

The App Is Now Open Source

The Mysterium VPN app repository is now public. This means the code that powers the Mysterium VPN app can be reviewed, run locally, and contributed to by anyone, not just the internal team.

What's in the Repository

The public repository includes:

• Instructions for preparing the development environment, running the app, generating code, and executing tests
• Documentation of the runtime configuration variables required for local development
• Contribution guidelines and code-style expectations
• A private process for reporting security vulnerabilities
• Public issue tracking and pull-request workflows

With sample configurations available, external contributors can run the app locally, inspect the code, report issues, and suggest improvements.

Why Open Source the App?

Opening the app code supports several goals:

• Transparency: Anyone can see how the app works, rather than taking it on faith.
• Community participation: Developers outside the core team can get involved directly.
• Easier external review: More eyes on the code means issues surface faster.
• More opportunities for contribution: The community can propose features and fixes, not just report bugs.

OpenVPN support for Android is the first concrete example of that process in action: a protocol addition shaped, in part, by opening the code to wider review.

What's Not Included

Publishing the app code doesn’t provide access to Mysterium VPN production systems or services. Normal authentication, subscription, and service-access requirements continue to apply. Only the app code itself is public — not the broader Mysterium VPN platform.

OpenVPN Support for Android (v2.4.8)

Mysterium VPN v2.4.8 adds OpenVPN as a supported protocol on Android, alongside WireGuard. Having more than one protocol available matters because some networks restrict or interfere with WireGuard connections specifically. When that happens, switching to OpenVPN can keep a connection alive without needing a different app or workaround.

That flexibility reaches beyond phones. OpenVPN's broad compatibility makes it a practical choice for using OpenVPN on older routers that predate newer protocols, and router-level coverage is what extends protection across a whole home network, including securing IoT and smart devices.

Users can select their preferred protocol from the app settings and switch between WireGuard and OpenVPN whenever needed.
