Grafana Mimir vs spiro

Grafana Mimir vs spiro: at a glance
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.
What is spiro?
Cardiopulmonary exercise test data in R, one metabolic cart vendor at a time.
spiro imports and processes cardiopulmonary exercise testing data in R, handling the file formats that metabolic carts from Cosmed, Cortex, Vyntus, and ZAN emit, then interpolating, smoothing, and summarizing them into comparable variables. The bulk of ongoing work is vendor format compatibility rather than analysis features — 0.2.4 fixed Cosmed imports failing in rare cases and Cortex imports on newer devices, and 0.2.2 added English-language Vyntus files after 0.1.2 added French ones. The analysis side, spiro_max(), spiro_smooth() and spiro_plot(), has been stable for some time.

Mimir's feed is a weekly Helm bot, with the 3.2 candidate the only real release in months
◆ 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.

Cardiopulmonary exercise test data in R, one metabolic cart vendor at a time.
◆ Current state
spiro imports and processes cardiopulmonary exercise testing data in R, handling the file formats that metabolic carts from Cosmed, Cortex, Vyntus, and ZAN emit, then interpolating, smoothing, and summarizing them into comparable variables. The bulk of ongoing work is vendor format compatibility rather than analysis features — 0.2.4 fixed Cosmed imports failing in rare cases and Cortex imports on newer devices, and 0.2.2 added English-language Vyntus files after 0.1.2 added French ones. The analysis side, spiro_max(), spiro_smooth() and spiro_plot(), has been stable for some time.
◆ Where it's heading
This is a mature rOpenSci package whose remaining work is dictated by other people's file formats. Each device firmware revision, each regional language variant, and each ggplot2 release generates maintenance, and that is what fills the changelog. The API itself settled early, with the 0.1.0 rOpenSci review pass renaming the protocol helpers to the pt_* prefix and 0.2.0 replacing the confusingly named spiro_import() with spiro_raw().
◆ Prediction
Expect the pattern to continue: import fixes as vendor formats shift and periodic plotting updates tracking ggplot2, with no indication of new analysis capability.
