AFFiNE vs Slack
A side-by-side editorial comparison of AFFiNE and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs Slack: at a glance
What is AFFiNE?
AFFiNE's canaries add managed AI model routing, with OpenRouter support for self-hosters.
AFFiNE's November 10 canaries rework its server-side Copilot: managed model routing with route choices and defaults, OpenRouter and more request formats, and route options for self-hosted deployments, while cloud deployments can no longer set provider profiles. A follow-up resizes images to WebP for AI chats and reports images that fail to load instead of dropping them. Earlier November canaries fixed CalDAV setup and item ordering.
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.

5.0COLLAB
AFFiNE's canaries add managed AI model routing, with OpenRouter support for self-hosters.
◆ Current state
AFFiNE's November 10 canaries rework its server-side Copilot: managed model routing with route choices and defaults, OpenRouter and more request formats, and route options for self-hosted deployments, while cloud deployments can no longer set provider profiles. A follow-up resizes images to WebP for AI chats and reports images that fail to load instead of dropping them. Earlier November canaries fixed CalDAV setup and item ordering.
◆ Where it's heading
After weeks of fixes and dependency bumps, the AI assistant is getting structural work: which model handles a request is becoming configurable, especially for self-hosters. Cloud and self-hosted setups are diverging in how much of that they control.
◆ Prediction
Expect more Copilot routing and error-handling fixes in the coming canaries; whether a stable release follows is not clear from the entries.

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.
