Open Source. Open Trust.
We believe in the power of open source. Honestly, transparency is the only way we know to earn your trust. That’s why every Oi app is open source—and every one has been independently audited and verified by third-party experts. You don’t have to take our word for it. Anyone can look at the code and see that our apps do exactly what we say they do.
Open source makes our products more secure
Open source isn’t just a nice idea—it makes our products safer. Oi’s open-source projects have been independently security-audited by thousands of experts around the world. You can read the audit reports, dig into the code yourself, or even contribute improvements. The door is open.
