Keybase vs Slack
A side-by-side editorial comparison of Keybase and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Keybase vs Slack: at a glance
What is Keybase?
Keybase's feed is mostly broken crawls; the one real release (v6.6.0) is iOS polish from March.
Three of the four entries the crawler captured are GitHub error pages ('Sorry, something went wrong') that mostly contain a username and the standard tab navigation — the crawler is hitting profile pages that load partially. The only real content is v6.6.0 on March 6, which shipped iOS sharing improvements, Emoji 16 support, HEIC avatars, and assorted fixes.
What is Slack?
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.

Keybase's feed is mostly broken crawls; the one real release (v6.6.0) is iOS polish from March.
◆ Current state
Three of the four entries the crawler captured are GitHub error pages ('Sorry, something went wrong') that mostly contain a username and the standard tab navigation — the crawler is hitting profile pages that load partially. The only real content is v6.6.0 on March 6, which shipped iOS sharing improvements, Emoji 16 support, HEIC avatars, and assorted fixes.
◆ Where it's heading
Keybase remains in slow-maintenance mode under Zoom: sporadic point releases focused on mobile niceties, no signs of a meaningful directional push. Confidence is limited by the source quality — half the feed is unusable.
◆ Prediction
Source likely needs re-pointing to the GitHub releases feed for the keybase/client repo to capture future releases reliably. Product itself probably ships another iOS-focused point release before any cross-platform feature lands.

6.3COMMSCOLLAB
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
◆ Current state
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.
◆ Where it's heading
Slack is positioning itself as both an MCP host (Slackbot calling external tools) and an MCP server (external agents acting in Slack), while Block Kit gains data-rich primitives and the streaming API matures for assistant experiences. The direction is making Slack a first-class surface for AI agents and data apps.
◆ Prediction
Expect deeper MCP capabilities and more data/visualization blocks, with continued frequent CLI/SDK releases supporting the agent-and-app platform push.
