leaflet vs Seurat
A side-by-side editorial comparison of leaflet and Seurat — release velocity, themes, recent moves, and the top alternatives to consider.
leaflet vs Seurat: at a glance
What is leaflet?
leaflet relicensed to MIT and finished migrating off R's retired spatial stack
leaflet is the R binding for the Leaflet mapping library. Its recent releases are dominated by one long migration: away from sp, rgdal, rgeos and raster, and toward sf and terra. Version 2.2.3 completed the user-facing half of that - sp is no longer installed by default, and bundled datasets ship as sf objects - while also relicensing the package from GPL-2 to MIT.
What is Seurat?
Seurat's centre of gravity has moved from single cells to spatial data and on-disk matrices
Seurat is the dominant R toolkit for single-cell analysis, and the 5.x line reads as two ongoing projects. One is spatial: successive releases absorb each new 10x output format - Visium HD, Xenium protein data, Space Ranger 4.0 segmentations - and add plotting and selection tools for them. The other is scale, where BPCells on-disk matrices keep gaining support in functions that previously required everything in memory.

leaflet relicensed to MIT and finished migrating off R's retired spatial stack
◆ Current state
leaflet is the R binding for the Leaflet mapping library. Its recent releases are dominated by one long migration: away from sp, rgdal, rgeos and raster, and toward sf and terra. Version 2.2.3 completed the user-facing half of that - sp is no longer installed by default, and bundled datasets ship as sf objects - while also relicensing the package from GPL-2 to MIT.
◆ Where it's heading
This is a package being brought into line with an ecosystem that changed underneath it. The retirement of rgdal and rgeos forced the terra and sf work; the license change and dependency reductions are the maintainers taking the opportunity to clean up while they are already in there. Feature work, such as the full viridisLite palette set, arrives as a side effect of the tidying.
◆ Prediction
With the sp path now opt-in and the retired geospatial dependencies gone, expect the remaining work to be small: palette and provider-tile handling, and keeping the bundled JavaScript current.
Seurat
0.0ANALYTICS
Seurat's centre of gravity has moved from single cells to spatial data and on-disk matrices
◆ Current state
Seurat is the dominant R toolkit for single-cell analysis, and the 5.x line reads as two ongoing projects. One is spatial: successive releases absorb each new 10x output format - Visium HD, Xenium protein data, Space Ranger 4.0 segmentations - and add plotting and selection tools for them. The other is scale, where BPCells on-disk matrices keep gaining support in functions that previously required everything in memory.
◆ Where it's heading
Both projects are driven from outside. The spatial work tracks whatever 10x ships, which is why data loaders and coordinate handling get rewritten release after release; the BPCells work tracks dataset sizes that no longer fit in RAM. Clustering and dimensionality reduction, the parts Seurat actually owns, change mainly by exposing more of uwot's and igraph's options rather than by new method development.
◆ Prediction
Expect the next release to absorb whatever instrument output 10x publishes next, and BPCells support to keep spreading into the functions that still densify matrices; the interactive spatial selection tooling looks like the one area with room to grow on its own terms.
