Miro vs Slack
A side-by-side editorial comparison of Miro and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Miro vs Slack: at a glance
What is Miro?
Miro is closing the gap between the workshop board and the deck built from it.
The board is becoming a source for generated deliverables: Miro AI now produces structured Slides presentations from scattered board content. Prototyping is the other heavy investment — an Advanced tab of 76 components, Code to Prototype, prototyping from screenshots and Figma, SVG and Copy-to-Figma export, connector visibility and precise sizing in Focus Modes. Diagramming continues to widen with an electrical-engineering shape pack and style-aware AI diagrams.
What is Slack?
Slack now hosts any A2A agent without Slack-specific code.
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.

Miro is closing the gap between the workshop board and the deck built from it.
◆ Current state
The board is becoming a source for generated deliverables: Miro AI now produces structured Slides presentations from scattered board content. Prototyping is the other heavy investment — an Advanced tab of 76 components, Code to Prototype, prototyping from screenshots and Figma, SVG and Copy-to-Figma export, connector visibility and precise sizing in Focus Modes. Diagramming continues to widen with an electrical-engineering shape pack and style-aware AI diagrams.
◆ Where it's heading
Miro is pushing outward at both ends of the canvas — generating the presentation that used to be built elsewhere afterwards, and generating prototypes from code, screenshots and Figma files beforehand. The canvas is being positioned as the middle of a pipeline rather than a standalone whiteboard.
◆ Prediction
Expect the Slides and Prototypes paths to keep converging on generation from existing artifacts, with the add-on boundary deciding how much of it is included.

6.3COMMSCOLLAB
Slack now hosts any A2A agent without Slack-specific code.
◆ Current state
Slack's developer channel is almost all agent plumbing. On 10 November Slack became an A2A (Agent2Agent) client: a team hosts its own agent, publishes an Agent Card, and Slack calls it when people talk to it, with no request URL, event handling or Slack-specific logic. This follows Slackbot skills managed through Web API methods, a Slack CLI that points coding agents to the Slack MCP server, and a new requirement that Work Objects embeds allow the slack-mcps.com frame ancestor.
◆ Where it's heading
Slack is lowering the cost of putting outside agents in front of its users: first skills as code, then MCP pointers for coding agents, now a standard protocol in place of the Slack app model for agents. The platform is positioning itself as the place where agents built anywhere meet the people who use them.
◆ Prediction
Expect more A2A follow-ups, such as agents appearing in Slackbot or skills surfaces and richer Agent Card features, given how fast the agent releases have stacked up since October.
