crosstalk vs loo
A side-by-side editorial comparison of crosstalk and loo — release velocity, themes, recent moves, and the top alternatives to consider.
crosstalk vs loo: at a glance
What is crosstalk?
crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.
crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.
What is loo?
loo keeps rewriting the diagnostics Bayesian modellers read off model comparison
loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.

crosstalk is frozen infrastructure: four releases in five years, mostly CRAN upkeep.
◆ Current state
crosstalk provides the shared-selection and filtering layer that lets independent htmlwidgets communicate on a page without Shiny. Its visible history is four releases across five years, one of which made a substantive change and three of which were fixes. The most recent exists only to clear an R CMD check NOTE.
◆ Where it's heading
The package is finished in the sense that matters: it does one thing, widget authors depend on it, and it changes when R or CRAN forces it to. The single directional move here is 1.2.0 dropping the bundled Bootstrap dependency so crosstalk stops imposing a CSS framework on the pages that embed it. Nothing since suggests further design work.
◆ Prediction
The next release is most likely another CRAN-compliance fix; the entries show no feature work in progress.

◆ Current state
loo computes leave-one-out cross-validation and model comparison for Bayesian models in the Stan ecosystem. Two releases in this window changed what users actually read: 2.7.0 replaced the fixed Pareto-k thresholds with sample-size-dependent ones and dropped the middle category, and 2.10.0 reshaped loo_compare's output into a data.frame with new uncertainty columns. The releases between are diagnostic robustness fixes and moment-matching corrections.
◆ Where it's heading
The package is being brought in line with the current PSIS literature rather than extended with new features, and the practical effect is that the numbers practitioners quote in papers keep changing meaning. Work is increasingly delegated to posterior for shared computations, and the project has added contributor process, benchmarks and a published AI contribution policy.
◆ Prediction
Expect further work on comparison diagnostics — the p_worse and diag_* columns are new enough that their defaults and documentation will likely be revised next.
