Mattermost
Mattermost leans hard into secure, on-prem collaboration for defense and regulated ops.
A side-by-side editorial comparison of Shortcut and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Shortcut is rebuilding its API for agents and pushing its Korey AI assistant beyond the app.
Two real threads run through the recent log: an API overhaul (coarse-grained token scopes, admin-scoped routes, and a v4 alpha explicitly aimed at agent compatibility) and the Korey AI assistant expanding to a Chrome extension usable on any webpage. Integration and roadmap polish round it out. Note that some recent feed items are brand-guide page content rather than product releases.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.

Shortcut is preparing its platform for agent-driven use, with scoped tokens and an agent-optimized API v4, while extending Korey outward from inside the app to anywhere the user works. The direction is a project tracker that both AI agents and humans can drive through a controlled API.
Expect API v4 to move from alpha toward general availability with agent-oriented capabilities, and Korey to gain more in-context actions across surfaces beyond the Chrome extension.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
