Threema ships a rare app change: spam reports for any chat on Android and iOS
A side-by-side editorial comparison of Salesmsg and Stream — release velocity, themes, recent moves, and the top alternatives to consider.
Salesmsg adds call-back requests and a one-click Emergency Stop for all outbound texts.
Salesmsg's autumn releases added survey automation, Click Tracking, upgraded Reviews and an official MCP server, then turned Sherpa AI into an assistant that sends replies and builds broadcasts after approval. The November 12 update moves to calling and safety controls: callers can request a callback instead of holding, Emergency Stop pauses every outbound message at once, inboxes can require call recording, tags can be applied during calls with HubSpot sync, and a weekly recap reports AI agent performance.
Stream ships open-source Vision AI SDK for multi-modal app testing
Stream offers two core infrastructure APIs: real-time chat/messaging for in-app communication, and a new open-source Vision AI SDK for building and testing multi-modal AI applications. The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.

With AI now able to send messages, Salesmsg is adding the brakes: an organization-wide stop switch and weekly reports on what its AI agents did. Calling features keep catching up with texting, with queue callbacks and recording rules.
Expect more controls over what Sherpa and AI agents may send, such as per-agent limits or approval rules, alongside further HubSpot call-data sync.

The Vision AI SDK supports live-edit-test workflows across modalities, targeting engineering teams iterating on AI features rather than end-user consumers.
Stream is extending beyond its established chat messaging infrastructure into AI-native developer tooling. The Vision AI SDK positions Stream as a building block for AI application developers, not just communication product teams. If this pattern continues, expect more AI-specific primitives shipped alongside the core messaging APIs.
The next move is likely deeper integration between the Vision AI SDK and Stream's existing messaging infrastructure, enabling AI apps that combine real-time communication with multi-modal inputs in a single SDK surface.
