Sigma Computing vs OpenHouse
A side-by-side editorial comparison of Sigma Computing and OpenHouse — release velocity, themes, recent moves, and the top alternatives to consider.
Sigma Computing vs OpenHouse: at a glance
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.
What is OpenHouse?
OpenHouse adds time-zone-aware retention and per-database table caps.
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.

Sigma Computing

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.
OpenHouse
5.0ANALYTICS
OpenHouse adds time-zone-aware retention and per-database table caps.
◆ Current state
OpenHouse ships small versioned releases straight from merged pull requests. On November 13 it shipped five: retention policies on string date columns can now take a time zone, operators can cap live tables per database with metrics on usage and rejections, view requests and operations are now audited in full, and two fixes make view property SET/UNSET and REPLACE behave. Earlier in November failed Spark maintenance jobs began exiting as failed.
◆ Where it's heading
OpenHouse is adding the controls a shared lakehouse needs at scale: quotas, audit trails and retention that matches business calendars. Views are getting the same governance tables already had.
◆ Prediction
Expect more views milestones after audit (the release is labeled Views M1), and further operator controls for quotas and maintenance.
