A side-by-side editorial comparison of Kaltura and Nextcloud Talk — release velocity, themes, recent moves, and the top alternatives to consider.
Kaltura vs Nextcloud Talk: at a glance
What is Kaltura?
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
Kaltura is in the middle of a sharp pivot toward agentic AI for rich-media platforms. In a single month it has open-sourced an AI Agent Skills suite (so any third-party AI agent can build rich-media experiences), introduced Event OS for AI Agents (natural-language event creation and orchestration), unveiled an avatar-powered roleplay solution for enterprise training, and is presenting an Agentic Revenue Engagement Platform at Forrester. The releases are tightly aligned around one thesis.
What is Nextcloud Talk?
Nextcloud Talk patches v22 and v23 while v25 stable sits five weeks past its last RC.
Nextcloud Talk's newest releases are maintenance drops for the v22 and v23 branches: a faster conversation-list unread cache, rate limiting on public-share and video verification, and a Matterbridge domain check against DNS rebinding. v23.0.12 also fixes SIP so direct incoming calls register as phone participants. The v25 line, which carries classified conversations, an owner role and configurable AI call summaries, has not moved past RC3 since September 10.

8.8MEETINGS
Kaltura goes all-in on agentic AI video — Event OS, avatar roleplay, and an open-sourced AI Agent Skills suite.
◆ Current state
Kaltura is in the middle of a sharp pivot toward agentic AI for rich-media platforms. In a single month it has open-sourced an AI Agent Skills suite (so any third-party AI agent can build rich-media experiences), introduced Event OS for AI Agents (natural-language event creation and orchestration), unveiled an avatar-powered roleplay solution for enterprise training, and is presenting an Agentic Revenue Engagement Platform at Forrester. The releases are tightly aligned around one thesis.
◆ Where it's heading
The arc is clearly from a video platform into an agentic-AI orchestration layer that happens to specialize in video. Kaltura is staking out the position that video, events, training, and revenue engagement should all be run through AI agents talking to its platform — and is willing to open-source the agent-skills layer to make Kaltura the default endpoint for rich-media agents.
◆ Prediction
Expect a paid agent runtime or pricing model on top of the open-sourced skills, deeper avatar/roleplay options for enterprise L&D, and Event OS plug-ins for major collaboration platforms (Teams, Slack, Google Workspace). The next big tell will be how serious enterprise adoption of Event OS becomes versus staying a demo-stage capability.
Nextcloud Talk
5.0MEETINGS
Nextcloud Talk patches v22 and v23 while v25 stable sits five weeks past its last RC.
◆ Current state
Nextcloud Talk's newest releases are maintenance drops for the v22 and v23 branches: a faster conversation-list unread cache, rate limiting on public-share and video verification, and a Matterbridge domain check against DNS rebinding. v23.0.12 also fixes SIP so direct incoming calls register as phone participants. The v25 line, which carries classified conversations, an owner role and configurable AI call summaries, has not moved past RC3 since September 10.
◆ Where it's heading
The feature story is still v25's compliance and governance set aimed at regulated, self-hosted deployments. Meanwhile the older branches are getting security hardening rather than features, which fits a team prioritizing stable-line safety before a major cut. The long gap after RC3 suggests the v25 release is gated on something not visible in these notes.
◆ Prediction
The next notable release is v25.0.0 stable or a further RC; the entries don't show why it has stalled, so timing is unclear.
