HOMER vs Kaltura
A side-by-side editorial comparison of HOMER and Kaltura — release velocity, themes, recent moves, and the top alternatives to consider.
HOMER vs Kaltura: at a glance
What is HOMER?
Homer's storage churn pauses long enough to ship a catalog backup CLI.
The release stream is a rapid sequence of production failures found and closed, nearly all of them in the DuckDB/DuckLake storage layer. 11.0.320 bounded a DuckDB compaction merge that was silently SIGKILLing the process with the catalog lock held and told operators not to switch to the native engine; 11.0.321 then made native compaction safe for a live catalog and added hours as a retention unit. 11.0.323 is the first quiet release in the run — a QoS chart axis fix for dashboard timezones, plus the catalog backup and restore CLI that shipped untagged in 11.0.322. Around these sit alert-query replay, per-user dashboard IDs, raised DuckDB memory caps for SIPREC ingest, and two inline GHSA fixes hardening node /query auth.
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.

HOMER
5.0MEETINGS
Homer's storage churn pauses long enough to ship a catalog backup CLI.
◆ Current state
The release stream is a rapid sequence of production failures found and closed, nearly all of them in the DuckDB/DuckLake storage layer. 11.0.320 bounded a DuckDB compaction merge that was silently SIGKILLing the process with the catalog lock held and told operators not to switch to the native engine; 11.0.321 then made native compaction safe for a live catalog and added hours as a retention unit. 11.0.323 is the first quiet release in the run — a QoS chart axis fix for dashboard timezones, plus the catalog backup and restore CLI that shipped untagged in 11.0.322. Around these sit alert-query replay, per-user dashboard IDs, raised DuckDB memory caps for SIPREC ingest, and two inline GHSA fixes hardening node /query auth.
◆ Where it's heading
Homer is stabilizing a storage rewrite by moving work out of DuckDB rather than tuning it further — native compaction merges in Go, outside DuckDB's memory_limit, and lets DuckLake alone allocate snapshot and file IDs, the exact behavior that corrupted catalogs before. A backup and restore path for the catalog is the logical next admission that the catalog is the thing most likely to break, and shipping it inside another release rather than tagging it separately fits a project releasing several times a week. Defaults stay conservative while each escape hatch is proven.
◆ Prediction
If native compaction holds up in the field, expect it to become the default engine and the DuckDB compaction path to be deprecated; the near-term releases will likely keep closing memory and catalog-locking edges around it.
Kaltura
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.
