What is Courier?

Courier is turning its notification API into a full messaging orchestration platform.

Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.

What is Wire?

Calling is the one surface Wire's web client touches in every documented release.

Wire's web app ships production tags every one to three weeks. Four of the last six carry real upstream release notes and two are bare tags with no GitHub release behind them at all; a third reached our feed looking bare only because Wire published the notes upstream three days after cutting the tag. The documented work concentrates on calling - audio processing, background effects, session recovery - with Files and Shared Drives as the secondary thread.

Courier is turning its notification API into a full messaging orchestration platform.

◆ Current state

Courier has evolved from a transactional notifications API into an orchestration platform anchored by Journeys, its event-driven workflow engine. Recent releases layer optimization and enterprise controls on top — A/B testing inside journeys, isolated environments, and reusable routing strategies. Design Studio has matured into the central authoring surface across email, SMS, push, in-app, and chat.

◆ Where it's heading

The build order is clear: ship the orchestration core first (Journeys, Design Studio, the MCP-aware CLI), then make it production-grade for larger teams. The last quarter is about optimization and governance — experiments, custom environments, decoupled routing — rather than net-new channels. AI is being threaded in as a feature, like localization, not a headline product.

◆ Prediction

Expect continued hardening of Journeys as the hub: more experiment types, richer per-variant analytics, and deeper AI assistance inside Design Studio.

5.0

Calling is the one surface Wire's web client touches in every documented release.

◆ Current state

Wire's web app ships production tags every one to three weeks. Four of the last six carry real upstream release notes and two are bare tags with no GitHub release behind them at all; a third reached our feed looking bare only because Wire published the notes upstream three days after cutting the tag. The documented work concentrates on calling - audio processing, background effects, session recovery - with Files and Shared Drives as the secondary thread.

◆ Where it's heading

Two threads run through the releases that document themselves. Calling is being hardened rather than widened: enhanced audio processing and WebSocket recovery were flipped on by default in early July, background effects were then chased for performance under system load through late July, and in the August release they land inside calls proper. The second thread is file collaboration, where Shared Drives gained filtering and sorting in late July. August adds a narrower third: a user-facing recovery path for Proteus decryption failures, which is encryption plumbing surfacing as something a person can act on.

◆ Prediction

The next documented release most likely continues on calling reliability or extends the background-effects work. Nothing in these entries points to a new surface opening.
