mlr3proba is shedding weight as its survival work moves into sibling packages
A side-by-side editorial comparison of probably and Trackingplan — release velocity, themes, recent moves, and the top alternatives to consider.
The package that made calibration a step instead of an afterthought.
probably started as a small utility for class predictions and equivocal zones, and version 1.0.0 turned it into tidymodels' calibration and uncertainty package: cal_plot_*, cal_estimate_*, cal_validate_* and cal_apply across binary, multiclass and regression problems, plus conformal prediction intervals. Since then the work has been consolidation — a large internal refactor with no API change, split conformal and conformal quantile regression, bound_prediction(), and required_pkgs() and butcher methods so conformal objects can be deployed and stripped.
Trackingplan turns tracking-plan validation into AI-assisted, consent-aware observability.
Trackingplan monitors analytics implementations for drift and now anchors its workflow on two pillars: an AI Debugger that supplies root-cause analysis and recommended fixes, and Consent Monitoring that watches CMPs for privacy compliance. Recent releases connect these — deep links from charts into RCA and Data Explorer, shareable warning links, and consolidated troubleshooting views.

The recent releases are about making these objects survive leaving the session. butcher and required_pkgs() methods are what a model needs to be pinned, containerised and served, and their arrival alongside workflows adding a tailor postprocessing stage and vetiver adding probably support points the same way: calibration is being moved out of analysis scripts and into the deployed pipeline. The cal_*_none() reference implementations are the tell that calibration is now something people tune rather than apply once.
Expect the calibration functions to be reachable directly from a tuned workflow's postprocessing stage rather than applied to predictions afterwards, following the tailor integration that workflows just shipped.

Recent releases connect these — deep links from charts into RCA and Data Explorer, shareable warning links, and consolidated troubleshooting views.
The product is moving from passive tracking-plan validation toward active, guided remediation. Each release tightens the loop between detecting a problem (a warning, a consent gap) and resolving it — AI Debugger is spreading from generic warnings to consent warnings, and the UI is being rebuilt around single-surface investigation rather than scattered reports.
Expect AI Debugger to reach more warning types and Consent Monitoring to add further CMP integrations, continuing the pattern of extending both features to new surfaces rather than shipping a new pillar.
