Slack
Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Linear and Miro — release velocity, themes, recent moves, and the top alternatives to consider.
Linear closes the loop from issue to shipped code, with agents doing the writing.
Linear has spent the past two months turning its agent from a planning aid into a coding participant. Code Intelligence gave the agent codebase reasoning, MCP brought in external context, Diffs added native review, and Coding sessions now let it write and ship code with Claude Code and Codex. The project tracker is becoming the place where work is also executed, not just coordinated.
Miro is turning its canvas into an AI prototyping surface, now wired to coding agents.
Miro is concentrating its release energy on the Prototypes add-on, steadily converting the whiteboard into a design-to-prototype workspace. Recent updates add prompt-driven prototype generation, screenshot- and Figma-based flow expansion, and an MCP bridge that pulls work straight from coding agents onto the canvas. The core diagramming product still ships incremental shape, markdown, and theming improvements alongside.
Linear has spent the past two months turning its agent from a planning aid into a coding participant.

The project tracker is becoming the place where work is also executed, not just coordinated.
The direction is unmistakable: Linear wants the full plan-write-review-ship loop to live inside its workspace. Each release this quarter has filled one gap in that loop, and the surrounding work (Slack/Teams channels, team documents, releases tracking) keeps feeding the agent more context to act on. Expect the boundary between Linear and the IDE/GitHub to keep blurring.
Next moves likely deepen the coding-session workflow visible in these entries: more review automation on top of Diffs, and tighter loops between agent-written PRs and deployment tracking via Releases.
Miro is concentrating its release energy on the Prototypes add-on, steadily converting the whiteboard into a design-to-prototype workspace. Recent updates add prompt-driven prototype generation, screenshot- and Figma-based flow expansion, and an MCP bridge that pulls work straight from coding agents onto the canvas. The core diagramming product still ships incremental shape, markdown, and theming improvements alongside.
The direction is clear: Miro wants the canvas to be where teams explore, compare, and align on product directions before code is committed. Tying the canvas to coding agents over MCP positions it upstream of the build process rather than as a parallel sketchpad. Expect the Prototypes add-on to keep absorbing AI capabilities that were previously the domain of dedicated prototyping tools.
Next likely move is deeper agent round-tripping — pushing canvas prototypes back into code or design tools — building on the MCP and Copy-to-Figma groundwork already shipped.
