What is Calibre-Web?
A yearly release cadence spent almost entirely on Kobo sync and self-hosting hardening.
Calibre-Web is a self-hosted web frontend for an existing Calibre ebook library. It ships roughly one consolidated release a year, each a large bundle in which a short new-feature list sits on top of a much longer set of bug and security fixes. The most recent releases added MOBI and audio metadata extraction on upload, reverse-proxy login via a shared secret header, multi-book editing, and Calibre 9 compatibility. Kobo e-reader sync absorbs a disproportionate share of every release.
What is Skedda?
Skedda Companion can now be pushed to every laptop through MDM for full presence data.
Skedda's last quarter has been about making the data it collects visible and usable: Occupancy Insights, multi-venue comparison, richer visit exports, a read-only API beta and a redesigned Visits page. Skedda Companion 1.2 now installs through Intune, Jamf, Kandji or any MDM and enrols users automatically, so check-ins can be verified from laptop presence without QR codes or hardware.

A yearly release cadence spent almost entirely on Kobo sync and self-hosting hardening.
◆ Current state
Calibre-Web is a self-hosted web frontend for an existing Calibre ebook library. It ships roughly one consolidated release a year, each a large bundle in which a short new-feature list sits on top of a much longer set of bug and security fixes. The most recent releases added MOBI and audio metadata extraction on upload, reverse-proxy login via a shared secret header, multi-book editing, and Calibre 9 compatibility. Kobo e-reader sync absorbs a disproportionate share of every release.
◆ Where it's heading
Development here is maintenance-shaped rather than expansion-shaped, and the shape is getting more pronounced: 0.6.27 lists two new features against roughly thirty fixes, where 0.6.25 a year earlier listed close to twenty additions. The sustained investment sits in two places — keeping Kobo sync working against a vendor API that keeps moving underneath it, and making the app behave correctly behind reverse proxies and in container deployments. Compatibility work with current Calibre and current Python versions is treated as release-blocking, which is the right read for a project whose value depends entirely on staying installable.
◆ Prediction
Given the cadence, expect the next release six to twelve months out as another consolidated bundle led by Kobo sync repairs and Python or Calibre compatibility work rather than new capability. Reverse-proxy authentication is the one area with visible recent momentum, so further authentication-integration options are the most plausible genuinely new addition.
Skedda
6.3COLLAB
Skedda Companion can now be pushed to every laptop through MDM for full presence data.
◆ Current state
Skedda's last quarter has been about making the data it collects visible and usable: Occupancy Insights, multi-venue comparison, richer visit exports, a read-only API beta and a redesigned Visits page. Skedda Companion 1.2 now installs through Intune, Jamf, Kandji or any MDM and enrols users automatically, so check-ins can be verified from laptop presence without QR codes or hardware.
◆ Where it's heading
Skedda is shifting from a booking front end to a source of workplace attendance data. Companion's MDM rollout aims at complete presence coverage, which makes the occupancy analytics and API more valuable as more laptops report in.
◆ Prediction
Expect occupancy and presence data to reach the API, since Skedda said more API capabilities are planned and Companion now feeds richer attendance data.
