All Android users can now verify whether their Mullvad VPN app is legitimate before downloading and installing it on their device.
That’s because Mullvad starts with version 2025.2, has done its Android VPN app to reproducible.
The move comes in an attempt to give users a reliable and secure VPN application. Reproducible Builds is a guarantee that the app you are installing has not been manipulated by malicious actors
Confirm your Mullvad Android app builds, bit-for-bit
By definition, “A building is reproducible if, considering the same source code, building environment and building instructions, there can be restoring bit-by-bit identical copies of all specified artifacts.”
In short, the app code you see when downloading the app must match the source code published by the app developers. This gives insurance that there has been no change during the construction process.
This comes when 2024 saw an increase in malicious free VPN apps. Cyber criminals are increasingly utilizing the high demand for Virtual Private Network (VPN) tools to spread malware via fake software that mimicked legitimate services.
VPN-based attacks have also continued in 2025, with Google warning of attackers using legitimate VPN applications as a back door to inject malware and get remote control of infected devices.
“We believe that transparency is crucial to security software. Investment in reproducible builds is a testimony to our obligation to give you a reliable and secure application,” wrote Mullvad, one of the best VPN providers in the market right now in its official announcement.
As of version 2025.2, our Android -app buildings are reproducible. This means that you can confirm that the app you download and install is built from the Open Source Code we publish. Read more here: https://t.co/gv1zh8no5oMay 9, 2025
As mentioned earlier, only Mullvad’s latest Android VPN app comes with reproducible builds at the time of writing.
It is not yet clear whether and when the company will expand this feature across its other applications. We approached Mullvad for clarification of this and updates the article when we know more.
The company now calls on all technically prone users to verify Mullvad buildings. The verification process requires some IT skills, but the VPN company has put together a set of instructions to help you do just that.
“To help ensure that we are able to produce reproducible buildings over time, we have added initial such checks to our Continuous Integration (CI) environment,” Mullvad added.
