Calibre vs Holistics
A side-by-side editorial comparison of Calibre and Holistics — release velocity, themes, recent moves, and the top alternatives to consider.
Calibre vs Holistics: at a glance
What is Calibre?
Calibre is tying every performance number back to the deploy that caused it.
The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.
What is Holistics?
After a summer fencing in its AI layer, Holistics points it at the question analysts get asked most.
Holistics ships short, frequent notes, and the August 31 pair is the first in months that adds capability rather than control. Analyze Changes lets any user right-click a data point and get a two-step investigation: whether the movement is statistically unusual at all, then which dimensions and segments drove it and by how much. Anomaly Detection scans a time-series metric against an expected range built from its own history and flags the outliers, with the resulting chart saveable to a dashboard. Both are named as parts of a new Smart Analysis surface. The weeks before were governance — redaction of data the AI may see, and an AI user attribute restricting what it can reach.

Calibre is tying every performance number back to the deploy that caused it.
◆ Current state
The August release brings deployments into Real User Monitoring: deploy markers run along the bottom of charts, hovering one reveals the commit, author, and time, and clicking through opens the commit in source control, with each deployment compared against the previous. The same day, Synthetic metrics moved from one page at a time to median aggregates across all pages, segmented by test profile, deployment, and page — so a regression can be identified as site-wide or isolated. Before that: automatic measurement of soft navigations in single-page apps, a site-scan crawler that discovers and maintains the monitored page list on its own, self-service SAML SSO with SCIM on the Team plan, and an organisation-wide audit log that exports as NDJSON or streams to a SIEM over signed webhooks.
◆ Where it's heading
Calibre is closing the loop between a metric moving and someone knowing why. Deployment attribution supplies the cause, the all-pages segmentation supplies the scope, and soft-navigation measurement fills the blind spot that made SPA numbers untrustworthy in the first place. Running alongside that is a distinctly enterprise track — SSO, SCIM, and an audit log with SIEM streaming are procurement requirements, and putting SAML on the Team plan rather than reserving it for Company is a deliberate move down-market with them.
◆ Prediction
Expect deployment attribution to grow into alerting — a regression tied to a specific commit is the natural trigger for a notification, and the pieces are now all in place. How far the site-scan crawler is meant to replace manual page management is not yet clear from these entries.

6.3ANALYTICS
After a summer fencing in its AI layer, Holistics points it at the question analysts get asked most.
◆ Current state
Holistics ships short, frequent notes, and the August 31 pair is the first in months that adds capability rather than control. Analyze Changes lets any user right-click a data point and get a two-step investigation: whether the movement is statistically unusual at all, then which dimensions and segments drove it and by how much. Anomaly Detection scans a time-series metric against an expected range built from its own history and flags the outliers, with the resulting chart saveable to a dashboard. Both are named as parts of a new Smart Analysis surface. The weeks before were governance — redaction of data the AI may see, and an AI user attribute restricting what it can reach.
◆ Where it's heading
The AI work has run in a recognizable order: capability, then observability, then access control, then redaction — and now capability again, but aimed somewhere new. Everything Holistics shipped before answered questions about building or querying; Smart Analysis answers why a number moved, which is the request that has always been routed to an analyst. Governance arriving first is what makes it viable: redaction and the AI user attribute decide what the investigator may look at before it is allowed to investigate on its own. Alongside it, presentation keeps moving into AML, so what analysts used to click is versioned as code.
◆ Prediction
The published roadmap already lists AI Dashboard Summaries and organization-level AI memory, so the next step is likely narrative output over the same investigation — an explanation attached to the dashboard rather than produced on right-click. Whether Smart Analysis stays a manual gesture or starts running unprompted against monitored metrics is the open question.
