Messenger (Meta)

Messenger is Meta's messaging app, consuming shared Meta client-infrastructure libraries alongside WhatsApp and Instagram. Referenced on this wiki as a deployment target for cross-product Meta libraries (media processing, RTC audio codecs) rather than as the subject of a deep-dive post.

• sources/2026-01-28-meta-rust-at-scale-an-added-layer-of-security-for-whatsapp — Messenger is one of three Meta products (WhatsApp + Messenger + Instagram) that receive the Rust-rewritten wamedia library monthly — "billions of phones, laptops, desktops, watches, and browsers."
• sources/2024-06-13-meta-mlow-metas-low-bitrate-audio-codec — Messenger is one of the platforms shipping Meta's MLow RTC audio codec (2× POLQA MOS over Opus at 6 kbps).
• sources/2026-04-09-meta-escaping-the-fork-webrtc-modernization — Messenger is one of the 50+ RTC use cases migrated onto the dual-stack WebRTC shim. The shim retires Meta's years-divergent libwebrtc fork while preserving per-app A/B testing of every new upstream Chromium release (launched webrtc/latest at M120, now at M145).
