OpenHouse vs Sigma Computing
A side-by-side editorial comparison of OpenHouse and Sigma Computing — release velocity, themes, recent moves, and the top alternatives to consider.
OpenHouse vs Sigma Computing: at a glance
What is OpenHouse?
LinkedIn's Iceberg control plane, shipping one pull request per release.
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
What is Sigma Computing?
Sigma is moving data modeling out of its own UI and into the terminal.
Sigma shipped a plugin for Claude Code that builds complete data models — metrics, relationships, columns, descriptions — from the terminal, alongside guidance on building Sigma Agents that handle schema discovery and model creation against Snowflake semantic views. Automated Actions landed for running reports, refreshing data, calling APIs, and triggering agents on a schedule, and embedded analytics gained bidirectional JavaScript events over postMessage.

OpenHouse

◆ Current state
OpenHouse is LinkedIn's open-source control plane for Iceberg tables, and it releases per merged pull request — version numbers climb several times a week with a single change each. The current work is concentrated on making the service defensible in production: a fix for CREATE OR REPLACE AS SELECT silently wiping table policies, request-ID correlation and a typed exception hierarchy in the data loader, and targeted scheduler logging for jobs observability.
◆ Where it's heading
The theme across these releases is treating table metadata as something that must not be lost by accident, and making failures attributable. Policies now merge rather than being rebuilt from the request. Data loader errors carry a request ID and distinguish authentication from transport failure instead of retrying auth errors as transient. Feature toggles gained self-service table overrides so server-side ramps and table-owner opt-in can coexist.
◆ Prediction
The jobs-observability plan explicitly defers OTEL gauges, a heartbeat sampler, and DLQ counters to a later phase, so those are the concrete next steps visible in these entries.
Sigma Computing
0.0ANALYTICS
Sigma is moving data modeling out of its own UI and into the terminal.
◆ Current state
Sigma shipped a plugin for Claude Code that builds complete data models — metrics, relationships, columns, descriptions — from the terminal, alongside guidance on building Sigma Agents that handle schema discovery and model creation against Snowflake semantic views. Automated Actions landed for running reports, refreshing data, calling APIs, and triggering agents on a schedule, and embedded analytics gained bidirectional JavaScript events over postMessage.
◆ Where it's heading
Two directions are converging on the same idea: Sigma as a system that runs without someone watching it. Automated Actions handles the scheduled half, the Claude Code plugin and agent guidance handle the authored half, and the embedding work makes Sigma a component inside someone else's application rather than a destination. The recurring argument in the writing — that read-only dashboards are no longer enough — is consistent across all three.
◆ Prediction
Expect the agent surface to extend from model creation into model maintenance, since schema drift is what makes hand-built models rot. The embedded and automation threads suggest write-back workflows will keep deepening.
