HumHub vs Slack
A side-by-side editorial comparison of HumHub and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
HumHub vs Slack: at a glance
What is HumHub?
HumHub 1.19 has left beta, and its first patches are already carrying security fixes.
The 1.19 cycle is out of beta. beta.3 in September carried security fixes, keyboard-accessibility work and leftover Bootstrap cleanup, and the v1.19.1 entry on October 26 is a changelog update noting security fixes, enhancements and bug fixes. HumHub's GitHub releases show 1.19.0 stable on October 12 and 1.19.3 on October 27, neither of which appears in this feed.
What is Slack?
Slack's CLI now points coding agents to its MCP server and Skills plugin
Slack's developer channel is mostly agent plumbing. Slackbot skills can be created and managed through Web API methods and kept current from CI, Slack Code lets agents open ephemeral channels with people, and the Slack CLI now tells coding agents that run slack --help about the Slack MCP and Skills Plugin. Alongside sit a new Block Kit layout block and tighter review rules for low-usage Marketplace apps.
HumHub vs Slack: editorial side-by-side
HumHub
2.5COLLAB
HumHub 1.19 has left beta, and its first patches are already carrying security fixes.
◆ Current state
The 1.19 cycle is out of beta. beta.3 in September carried security fixes, keyboard-accessibility work and leftover Bootstrap cleanup, and the v1.19.1 entry on October 26 is a changelog update noting security fixes, enhancements and bug fixes. HumHub's GitHub releases show 1.19.0 stable on October 12 and 1.19.3 on October 27, neither of which appears in this feed.
◆ Where it's heading
The betas were spent making the upgrade survivable, and the post-stable patches show what that missed: the 1.19.3 changelog repairs activity types that reappeared in e-mail summaries after the update, and a cron failure that could repeat summary mail. Accessibility is the one forward-looking thread, with visible focus and corrected tab order across cards, dropdowns and search.
◆ Prediction
1.19.4 is already listed as unreleased in the project changelog, so another fix-led patch is close. 1.18.7 shipped the same day as 1.19.2, so expect security fixes to keep reaching both lines.
Slack
5.0COMMSCOLLAB
Slack's CLI now points coding agents to its MCP server and Skills plugin
◆ Current state
Slack's developer channel is mostly agent plumbing. Slackbot skills can be created and managed through Web API methods and kept current from CI, Slack Code lets agents open ephemeral channels with people, and the Slack CLI now tells coding agents that run slack --help about the Slack MCP and Skills Plugin. Alongside sit a new Block Kit layout block and tighter review rules for low-usage Marketplace apps.
◆ Where it's heading
Slack is treating AI agents as a primary audience for its developer surface: skills as code, agent workspaces in channels, and now CLI help text written for agents to read. The Marketplace change points the other way, toward less attention for apps nobody installs.
◆ Prediction
Expect more of the CLI and API surface to be documented for agents, likely more MCP-exposed Slack actions. The entries do not show when Slack Code or skills leave developer preview.
