Tox is a privacy-centric messaging application that emphasizes decentralization and security, making it suitable for users who prioritize privacy over convenience. In contrast, Facebook Messenger offers a feature-rich experience with extensive integrations and a large user base, but it comes with privacy trade-offs and a need for a Facebook account.
