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 OpenReplay?

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

Fathom Analytics vs OpenReplay: editorial side-by-side

Fathom Analytics logo1.3

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.

5.0

OpenReplay moves its Go backend to pgx v5 and patches vulnerable deps across 1.25–1.27.

◆ Current state

On Oct 28 OpenReplay pushed backup tags on the 1.25, 1.26 and 1.27 lines that migrate the Go backend to pgx v5, bump vulnerable Go dependencies such as golang.org/x/net, and then fix a replay query that broke under the migration by casting issue_types to text. The previous days moved the assist and sourcemap-reader services to Node 26 LTS on the same lines and on 1.22.

◆ Where it's heading

The release feed is all maintenance: dependency and runtime upgrades backported to several self-hosted lines at once, published as timestamped backup tags without feature notes. The quick follow-up fix shows the pgx migration is touching real query paths.

◆ Prediction

Expect more backup tags as the pgx v5 change reaches 1.22 and any further query fixes land; nothing in the entries points to a feature release.
