Fathom Analytics vs OpenCTI: at a glance
What is Fathom Analytics?
Fathom rebuilds its query engine and bolts on Search Console, reaching for GA4's lunch.
Fathom shipped a complete analytics-engine rebuild in March 2026, paired with secondary dimensions, faster queries, and more accurate time-on-page measurement. The product is closing the feature gap with mainstream analytics tools while keeping its cookie-free, privacy-first stance. Recent additions — Google Search Console integration, entry/exit pages, dashboard ZIP exports, and a fresh layer of bot detection — directly target reasons users still keep GA4 open in another tab.
What is OpenCTI?
OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
OpenCTI ships on a roughly weekly date-stamped cadence, and the last six releases divide cleanly: the connector catalog was redesigned into a faceted marketplace, then the surrounding integrations experience was reworked around it, then the platform gained two-way connection with Filigran's XTM Hub. Alongside that, saved searches and saved filters became shareable and reusable across dashboards. The most recent releases are weighted toward fixes rather than new surface.

Fathom Analytics

Fathom rebuilds its query engine and bolts on Search Console, reaching for GA4's lunch.
◆ Current state
Fathom shipped a complete analytics-engine rebuild in March 2026, paired with secondary dimensions, faster queries, and more accurate time-on-page measurement. The product is closing the feature gap with mainstream analytics tools while keeping its cookie-free, privacy-first stance. Recent additions — Google Search Console integration, entry/exit pages, dashboard ZIP exports, and a fresh layer of bot detection — directly target reasons users still keep GA4 open in another tab.
◆ Where it's heading
The roadmap is clearly aimed at making Fathom a viable single-pane replacement for Google Analytics rather than a privacy-first complement to it. Expect continued investment in detection accuracy, reporting depth (custom exports, secondary dimensions), and Google-side integrations. The new analytics engine is foundational — it is what makes the next layer of features possible.
◆ Prediction
Next likely moves are deeper UTM and campaign analytics, an experimentation or goals-funnel surface, and tighter agency tooling that builds on self-serve site transfer and shared-dashboard exports.
OpenCTI
6.3ANALYTICS
OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
◆ Current state
OpenCTI ships on a roughly weekly date-stamped cadence, and the last six releases divide cleanly: the connector catalog was redesigned into a faceted marketplace, then the surrounding integrations experience was reworked around it, then the platform gained two-way connection with Filigran's XTM Hub. Alongside that, saved searches and saved filters became shareable and reusable across dashboards. The most recent releases are weighted toward fixes rather than new surface.
◆ Where it's heading
The centre of gravity is moving from OpenCTI as a self-contained platform to OpenCTI as a client of Filigran's wider ecosystem — connectors sourced from a catalog with support tiers, custom views deployed from XTM Hub, an MCP server exposed through XTM One. The workflow engine is maturing in parallel, picking up draft approval, transition restrictions and full reset. Telemetry coverage expanded significantly in the same period, which is what makes the catalog's adoption measurable.
◆ Prediction
Expect more of the platform's configuration surface — dashboards, playbooks, mappers — to become distributable through XTM Hub the way custom views and connectors already are. The workflow approval features suggest governance controls are the next area to fill in.
