Rigorous Cross-Platform Validation of a Matrix Stack: Edge-Case Testing WebRTC, VPNs, and Push Notifications
Self-hosting your communication infrastructure shouldn’t mean accepting a subpar user experience. When organizations move away from Big Tech infrastructure—specifically by stripping Google’s Firebase Cloud Messaging (FCM) out of their Android fleets—the common wisdom is that they must sacrifice battery life and reliability in the name of privacy. We recently set out to prove that assumption…
