cfr vs Grafana Mimir
A side-by-side editorial comparison of cfr and Grafana Mimir — release velocity, themes, recent moves, and the top alternatives to consider.
cfr vs Grafana Mimir: at a glance
What is cfr?
cfr packaged delay-corrected severity estimation, then went quiet on maintenance.
The package estimates disease severity and case ascertainment while correcting for the delay between a case being reported and its outcome being known. After the 0.1.1 rework of the estimation internals and a maintainer handover to Adam Kucharski, activity dropped to a vignette and an R-devel compatibility patch in February 2025.
What is Grafana Mimir?
Mimir's feed is a weekly Helm bot, with the 3.2 candidate the only real release in months
The visible cadence is an automated weekly Helm chart release opened by a bot with a two-line body, now at 6.3.0-weekly.408. The only substantive entry in the window is the 3.2.0 release candidate from early August, which carried query engine work and native histogram support.

◆ Current state
The package estimates disease severity and case ascertainment while correcting for the delay between a case being reported and its outcome being known. After the 0.1.1 rework of the estimation internals and a maintainer handover to Adam Kucharski, activity dropped to a vignette and an R-devel compatibility patch in February 2025.
◆ Where it's heading
The methodological work is done and consolidated: likelihood approximation is now selected automatically from outbreak size and an initial severity estimate, and the internals were renamed with a dot prefix to close the public surface down to cfr_static(), cfr_rolling() and the data-preparation generic. Releases since have been documentation and compatibility only.
◆ Prediction
The 0.1.0 notes flagged time-varying ascertainment as future work and it has not appeared in the two releases since; nothing in these entries indicates when or whether it lands.

◆ Current state
The visible cadence is an automated weekly Helm chart release opened by a bot with a two-line body, now at 6.3.0-weekly.408. The only substantive entry in the window is the 3.2.0 release candidate from early August, which carried query engine work and native histogram support.
◆ Where it's heading
Packaging and the engine move on separate clocks: the chart ships weekly regardless of whether anything changed underneath, while Mimir itself cuts a minor roughly monthly. The weekly stream tells you nothing about direction and will keep dominating the feed by volume.
◆ Prediction
The chart line moving from 6.2.0-weekly to 6.3.0-weekly points at a 6.3.0 chart release carrying Mimir 3.2 once the candidate goes final.
