What is Beeper?

Beeper stopped aggregating apps and started merging the people inside them.

The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.

What is Slack?

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

Beeper stopped aggregating apps and started merging the people inside them.

◆ Current state

The bridge count keeps climbing, with LINE the most recent addition, but the more consequential work is identity-level. Merge Chats collapses conversations with the same person across multiple networks into a single thread. Around that sits a long run of parity work — group chat creation, delete chat, disappearing messages, message requests — closing the gaps that forced users back into native clients.

◆ Where it's heading

Two tracks run in parallel. Parity work is making Beeper safe to use as the only client, and for the major networks it is close to finished. On top of that, the product is starting to add things no native app can do: cross-network chat merging, in-chat AI models, a unified requests folder. The public call for third-party bridges suggests network coverage is increasingly a community responsibility rather than an in-house roadmap item.

◆ Prediction

With conversations merged across networks, unified contacts and cross-network search are the natural follow-ons — the organizing primitive shifts from the chat to the person.

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.

◆ Current state

Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.

◆ Where it's heading

The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.

◆ Prediction

The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.
