Signal features and specs

• End-to-End Encryption
  Signal uses end-to-end encryption to ensure that only the sender and the recipient can read the messages. This makes it highly secure against eavesdropping.
• Open Source
  Signal's code is open source, allowing anyone to inspect, audit, and improve it. This transparency helps to build trust and ensure the security of the platform.
• User Privacy
  Signal is designed to collect minimal data from its users. It does not store metadata about contacts, messages, or user activity, thereby prioritizing user privacy.
• Cross-Platform Availability
  Signal is available on a variety of platforms including iOS, Android, and desktop, making it accessible to a broad range of users.
• Multi-purpose Usage
  Beyond just text messaging, Signal supports voice and video calls, as well as file sharing, making it a versatile communication tool.

Possible disadvantages of Signal

• Limited User Base
  Compared to more popular messaging apps like WhatsApp and Facebook Messenger, Signal has a smaller user base, which may limit its utility as a communication tool.
• Dependence on Phone Number
  Signal requires users to register with a phone number, which can be a privacy concern for some people who prefer not to share their number.
• Backup Limitations
  Signal does not offer cloud backups for messages, which means users have to rely on local backups that can be more cumbersome to manage.
• User Interface
  Some users find Signal's user interface to be less polished and user-friendly compared to other mainstream messaging apps.
• Notification Issues
  There have been reports of unreliable notifications that can result in missed messages or calls, potentially impacting the user experience.

WebRTC features and specs

• Real-time Communication
  WebRTC enables real-time voice, video, and data communication directly between web browsers and other devices without requiring plugins or additional frameworks.
• Open Source
  WebRTC is free and open-source, which allows developers to inspect, modify, and enhance the code to suit their needs without incurring licensing costs.
• Peer-to-Peer Architecture
  The peer-to-peer architecture of WebRTC reduces latency and can be more efficient than server-based architectures for real-time communication, saving bandwidth and server resources.
• Cross-Platform Compatibility
  WebRTC operates seamlessly across different platforms (web, mobile, desktop) and operating systems, ensuring broad accessibility and reach.
• Built-in Security
  WebRTC comes with built-in security features such as encryption of data streams (SRTP) and secure access to media devices, which enhances user privacy and data security.

Possible disadvantages of WebRTC

• Network Traversal Issues
  WebRTC can face challenges with firewall and NAT traversal, which might require additional setup and infrastructure like TURN servers to relay traffic.
• Browser Compatibility
  While most modern browsers support WebRTC, there may still be inconsistencies or issues with certain browsers or versions, necessitating thorough compatibility testing.
• Scalability Challenges
  Handling large-scale implementations or group calls can be challenging with WebRTC's peer-to-peer architecture, often requiring additional signaling servers and infrastructure.
• Lack of Quality Control
  WebRTC doesn’t have built-in mechanisms for monitoring and controlling the quality of service (QoS), which can lead to variations in audio and video quality especially under poor network conditions.
• Complexity of Implementation
  Building a complete WebRTC-based application can be complex due to the need for handling signaling, session management, and potential browser-specific issues.
