Retool
Retool is retiring standalone Assist while folding the same capability into the app builder.
A side-by-side editorial comparison of estimatr and openairmaps — release velocity, themes, recent moves, and the top alternatives to consider.
Fast design-based estimators for experiments, coasting on CRAN patches.
estimatr provides the design-based regression estimators the DeclareDesign ecosystem is built on — robust and cluster-robust standard errors, blocked and clustered randomization inference — implemented for speed rather than generality. The last three releases carry no substantive notes: each is a merge commit for a CRAN patch, one of them accompanied by a typo fix.
The mapping half of the openair stack, currently dismantling its own static plotting in favour of the parent package.
openairmaps puts openair's air quality analysis onto interactive maps — polar markers on leaflet, trajectory paths and gridded trajectory levels, and popup construction from site metadata. It now requires openair 3.0.0 and R 4.1, and its polar markers are drawn by ggplot2 as a consequence, which brought a theme argument for customising them. The latest release turns off the automatic captions that openair 3.1.0 started adding, and points the remaining static trajectory functions at openair's own implementations.

Direction cannot be read from this feed. The release notes are unedited merge-commit messages, so the only signal is cadence — roughly annual, each release framed as a CRAN patch rather than as feature work. That pattern is consistent with a package whose estimators are considered finished and which now moves only when CRAN policy requires it.
On the evidence here the next release is another CRAN compliance patch, but the notes are too thin to support a confident read of what the maintainers are actually working on.

This package follows rather than leads. The ggplot2 polar markers, the pipe change, and the R version floor all arrived because the parent package moved first, and the two now ship within hours of each other. The clearer local trend is contraction: the polarMapStatic() family has been removed outright, the static trajectory functions are now thin wrappers around openair equivalents with removal stated as the plan, and argument names keep being retired in favour of openair's. The package is narrowing toward the one thing openair does not do — interactive maps.
The static trajectory wrappers are explicitly flagged for removal, so the next significant release should drop them and leave the package purely interactive.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Infra & APIs. estimatr and openairmaps are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. estimatr and openairmaps are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
