At Proton, our commitment to transparency and privacy has always guided how we develop our services. We believe you must be able to investigate and verify apps for yourself if you want to make an informed decision about what happens to your data. Today, we’re proud to announce that all Proton Drive apps are now fully open source, including the Proton Drive desktop apps.
This milestone underscores our mission to build privacy-first solutions that you can trust. By making all our apps open source, we empower our community and the broader security sphere to inspect, verify, and trust the protections we’ve built into Proton Drive to safeguard your data.
You can find the source code for all Proton Drive apps.

Why open source matters
Making our apps open source is one way we demonstrate our belief that privacy shouldn’t require blind trust. By providing full access to our source code, we enable anyone to verify that our apps function as promised, delivering the security and privacy we claim.
Sharing our apps’ source code publicly also allows us to leverage the security community to quickly find, identify, and resolve potential vulnerabilities rather than rely on security through obscurity. Developers, security researchers, privacy advocates, and anyone who is interested can inspect any Proton Drive app. This transparency strengthens the security of our services and gives our users full confidence in how their data is protected.
We believe that open-source code is one of the keys to building a better internet where privacy is the default. In addition to making our apps open source, we maintain two of the most popular open-source cryptographic libraries (OpenPGP.js(nieuw venster) and GopenPGP(nieuw venster)) that make it easier for developers to secure their apps with strong encryption. We also regularly support open-source projects with our Lifetime Account Charity Fundraiser, such as WireGuard, Qubes OS, and Tails.
Get involved
We believe that the privacy and security of the internet is a collective effort. By making our code freely available, we’re empowering everyone to contribute to the future of online privacy and security. Explore our code on GitHub(nieuw venster), participate in our Bug Bounty Program, and join us in building a more private and secure internet.
