WebRTC Weekly Issue #662 highlights significant version fragmentation in native WebRTC SDKs, with some vendors lagging up to 30 months behind Chrome's release cycle. The issue also covers the launch of Element's MatrixRTC for decentralized calling and a critical security vulnerability in Signal's RingRTC library.
The widening gap between browser-based WebRTC and native SDKs creates a fragmented security landscape where mobile apps remain vulnerable to bugs already patched in Chrome. As libwebrtc enters a maintenance phase with fewer external contributors like Philipp Hancke, the burden of maintaining homegrown collectors and custom modules like those in mediasoup increases for developers. This shift toward decentralized options like MatrixRTC and the retirement of Azure Communication Services suggests a market pivot away from general-purpose hyperscaler APIs toward specialized or sovereign communication stacks. Watch for whether other major CPaaS vendors accelerate their libwebrtc integration cycles to match the new two-week browser release cadence.
Native video platforms are experiencing significant WebRTC SDK fragmentation, with some lagging up to 30 months behind Chrome's two-week update cycle. This gap leaves mobile applications vulnerable to security flaws already patched in browsers. Consequently, the industry is shifting toward decentralized alternatives like MatrixRTC and specialized communication stacks over general-purpose APIs.
Native SDKs from seven major video platforms show update delays ranging from 1.5 to 30 months compared to the Chrome M156 release.
MatrixRTC is a decentralized, end-to-end encrypted alternative to centralized group calling services, recently launched by Element.
Microsoft is retiring standalone Azure Communication Services by September 2028, limiting future calling features to Teams-integrated use cases.
CVE-2026-113380 was a critical security flaw in Signal's RingRTC library that allowed audio and video transmission to continue even after users hung up.
