Umami vs Sigma Computing

Umami vs Sigma Computing: at a glance
What is Umami?
Umami spent late 2025 patching Next.js CVEs, then shipped Boards and Session Replay in v3.1.0.
The window splits sharply. Four of six releases are December 2025 patches across the v2 and v3 lines, all responding to the same Next.js and React security advisories plus Docker build breakage — several shipped within days of each other because the first fix updated Next.js without the affected React versions. Then v3.1.0 in April 2026 delivered custom dashboards as Boards, Session Replay, Web Vitals performance tracking, a redesigned share page, and a large batch of fixes.
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.

◆ Current state
The window splits sharply. Four of six releases are December 2025 patches across the v2 and v3 lines, all responding to the same Next.js and React security advisories plus Docker build breakage — several shipped within days of each other because the first fix updated Next.js without the affected React versions. Then v3.1.0 in April 2026 delivered custom dashboards as Boards, Session Replay, Web Vitals performance tracking, a redesigned share page, and a large batch of fixes.
◆ Where it's heading
The security cluster is a framework dependency showing its cost — an analytics tool inheriting its release schedule from Next.js advisories. v3.1.0 is where product work resumes, and its content is telling: Session Replay and Web Vitals move Umami past pageview counting into behaviour and performance, which is the territory occupied by heavier commercial analytics rather than the lightweight privacy-first tools it grew up alongside.
◆ Prediction
Expect the next releases to build on Boards and Session Replay rather than return to the counting core, since both are new surfaces that arrived with a single release and no follow-up yet.
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.
