What is Nextcloud?

Nextcloud runs three LTS branches in parallel, shipping bug fixes and quiet performance wins.

Nextcloud is simultaneously maintaining three major release lines (32.x, 33.x, 34.x), publishing patch updates every few weeks. Recent work fixes file-sharing edge cases, corrects share permission logic, and patches OCM federation bugs. Performance work targets group membership lookups, swapping full group-object fetches for leaner ID-only queries across branches.

What is Zulip?

Zulip donates itself to a nonprofit foundation as its founder joins Anthropic.

Two consequential moves landed inside three weeks. Tim Abbott, Zulip's longtime leader, is stepping back to join Anthropic along with three senior Kandra Labs engineers, and the for-profit company is being donated to a newly formed independent Zulip Foundation. In parallel, Zulip Server 12.0 shipped — roughly 5,500 commits, end-to-end encryption for mobile push notifications, a major Docker upgrade, and configurable image previews — alongside routine 11.x security patches and a self-hosted AI search integration via Atolio.

Nextcloud vs Zulip: editorial side-by-side

N
Nextcloud
COLLAB
5.0

Nextcloud runs three LTS branches in parallel, shipping bug fixes and quiet performance wins.

◆ Current state

Nextcloud is simultaneously maintaining three major release lines (32.x, 33.x, 34.x), publishing patch updates every few weeks. Recent work fixes file-sharing edge cases, corrects share permission logic, and patches OCM federation bugs. Performance work targets group membership lookups, swapping full group-object fetches for leaner ID-only queries across branches.

◆ Where it's heading

The three-track maintenance cadence signals a hardening phase following v34's release, prioritizing stability over new surface area. OCM fixes accumulating across branches suggest cross-instance federation use is growing and generating real-world bug reports. If this pattern holds, a v35 feature push is the next inflection point — the current batch is largely invisible to end users.

◆ Prediction

The next meaningful surface change will likely come with v35 feature work; the cross-branch group-query performance push and OCM federation fixes hint that enterprise scale and cross-instance collaboration are the focus areas going into the next major.

5.0

Zulip donates itself to a nonprofit foundation as its founder joins Anthropic.

◆ Current state

Two consequential moves landed inside three weeks. Tim Abbott, Zulip's longtime leader, is stepping back to join Anthropic along with three senior Kandra Labs engineers, and the for-profit company is being donated to a newly formed independent Zulip Foundation. In parallel, Zulip Server 12.0 shipped — roughly 5,500 commits, end-to-end encryption for mobile push notifications, a major Docker upgrade, and configurable image previews — alongside routine 11.x security patches and a self-hosted AI search integration via Atolio.

◆ Where it's heading

Governance is being separated from product velocity: the foundation owns long-term stewardship while the technical roadmap (E2E push, self-hostable AI integrations, hardened install path) keeps targeting security-conscious, self-hosted teams. Losing the founder to a frontier AI lab is the kind of transition that either accelerates community ownership or stalls momentum — the 12.0 commit volume suggests the team built up runway before the announcement.

◆ Prediction

Expect the Zulip Foundation to publish formal governance, a maintainer charter, and a funding model in the next quarter, and for the AI integration story (Atolio-style connectors rather than first-party AI) to harden into Zulip's positioning against Slack and Mattermost's first-party AI bets.
