GoKawiil's interpretation of the reporting above, not reported fact.
Password managers require users to trust software with highly sensitive data, and full source availability lets security researchers audit the code rather than relying on vendor claims. A local-first, copyleft-licensed approach also appeals to users wary of cloud-based managers that have suffered breaches, positioning Sesame as a transparency-focused alternative in a market dominated by closed-source incumbents.
- Sesame is fully open-source under AGPL-3.0-or-later, meaning any modifications must also be shared publicly.
- The password manager is designed to be local-first, reducing reliance on third-party cloud infrastructure.
- High recent commit activity (147 in 30 days) suggests an actively maintained, early-stage project.
