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 Hex?
Hex turns its agent from a query helper into a governed app builder.
Hex now ships weekly around two surfaces: the Hex Agent and Generative Apps. The agent builds projects from chat, runs under published eval suites, and works through Slack, CLI and API; Generative Apps have gained chat, scheduled exports, direct text editing and targeted chart edits. The latest release adds classifications of agent activity, giving admins a view of what the team actually asks the agent to do.

Calibre

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.
Hex
6.3ANALYTICS
Hex turns its agent from a query helper into a governed app builder.
◆ Current state
Hex now ships weekly around two surfaces: the Hex Agent and Generative Apps. The agent builds projects from chat, runs under published eval suites, and works through Slack, CLI and API; Generative Apps have gained chat, scheduled exports, direct text editing and targeted chart edits. The latest release adds classifications of agent activity, giving admins a view of what the team actually asks the agent to do.
◆ Where it's heading
The work has shifted from adding agent capability to making that capability manageable: evals, approval skipping, bring-your-own-provider, model visibility, and now usage classification. Generative Apps are being rounded out in parallel so that agent-built output can be edited, shared and scheduled like a regular Hex app.
◆ Prediction
Expect the activity classifications to feed further admin tooling, such as usage reporting tied to credits or evals, alongside continued weekly iteration on Generative App editing.
