• End-to-End Encryption
  Keybase provides end-to-end encryption for messages and files, ensuring that only the intended recipients can read the data.
• Cross-Platform
  Keybase is available on multiple platforms, including Windows, macOS, Linux, iOS, and Android, making it accessible from virtually any device.
• Public Key Directory
  It serves as a public key directory, simplifying the process of finding and verifying colleagues and acquaintances for secure communication.
• Integration with Social Media
  Users can verify their identities by linking their social media profiles, providing an additional layer of trust and authenticity.
• Team Collaboration Features
  Keybase offers robust team collaboration features, including secure team messaging and file-sharing capabilities.
• Open Source

Possible disadvantages

• User Base
  The user base is relatively small compared to mainstream messaging apps, which may limit its usefulness for communication with non-tech-savvy individuals.
• Learning Curve
  New users may find Keybase complicated to set up and use, especially those who are not familiar with encryption and public key infrastructure.
• Resource Intensive
  The application can be resource-intensive, potentially affecting performance on older or low-specification devices.
• Centralized Service
  Despite its security features, Keybase's reliance on a centralized service can be a point of failure or a target for attacks.
• Dependency on Linked Services
  The identity verification process relies heavily on linking to external social media profiles, which may not be ideal for users who prefer to maintain strict separation of their online identities.
• Limited Offline Access
  Keybase requires an internet connection for most of its functionalities, making it less useful in offline scenarios.
