EGroupware vs Slack
A side-by-side editorial comparison of EGroupware and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
EGroupware vs Slack: at a glance
What is EGroupware?
Two branches, one deadline: 23.1 security coverage ends August 15th and 26.x is the only exit.
EGroupware is releasing date-stamped builds on two branches simultaneously, and July was almost entirely security. Three separate advisory waves shipped in a fortnight, twice requiring a same-day follow-up build for vulnerabilities reported after the first fix went out. The 23.1 branch now carries an explicit end date: security coverage stops on August 15th 2026.
What is Slack?
Slack is shipping its developer platform to coding agents, not only to developers.
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.

EGroupware
5.0COLLAB
Two branches, one deadline: 23.1 security coverage ends August 15th and 26.x is the only exit.
◆ Current state
EGroupware is releasing date-stamped builds on two branches simultaneously, and July was almost entirely security. Three separate advisory waves shipped in a fortnight, twice requiring a same-day follow-up build for vulnerabilities reported after the first fix went out. The 23.1 branch now carries an explicit end date: security coverage stops on August 15th 2026.
◆ Where it's heading
Underneath the advisory churn, the 26.x branch is where anything new lands — AiTools gained prompts that fire on entry add, update and delete rather than only from a context menu, and can chain up to five tool calls per prompt; Invoices gained OCR that identifies document type and billing period. Meanwhile CalDAV and ActiveSync fixes keep recurring, the fallout of an internal move from timestamps to DateTime objects in Calendar.
◆ Prediction
Expect a final 23.1 security build before the August 15th cutoff and continued 26.x releases where the AiTools trigger and tool-calling work is the thread to watch.
Slack
6.3COMMSCOLLAB
Slack is shipping its developer platform to coding agents, not only to developers.
◆ Current state
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.
◆ Where it's heading
The MCP and Skills plugin is the clearest signal of where this is going: Slack is packaging its own platform knowledge for consumption by coding agents, and naming Claude Code and Cursor as the first targets rather than shipping a generic endpoint. Meanwhile the SDK work is clearing debt that would get in the way, dropping axios for native Fetch, removing the deprecated Workflow Steps from Apps feature, and raising the Node floor to 20. Modern runtime, fewer legacy surfaces, then agent access on top.
◆ Prediction
The plugin ships for two named agent clients today, so the obvious next step is broadening that list or folding the skills into the CLI itself. The entries do not indicate whether Slack intends the MCP server to reach runtime app behaviour or stay a build-time developer aid.
