geobounds vs tulpa
A side-by-side editorial comparison of geobounds and tulpa — release velocity, themes, recent moves, and the top alternatives to consider.
geobounds vs tulpa: at a glance
What is geobounds?
geobounds relicensed to MIT and drew a line between its code and the data it downloads.
geobounds is an R client for the geoBoundaries administrative boundary database. Version 1.0.0 relicensed the package itself from CC BY 4.0 to MIT while documenting that downloaded boundaries keep their own terms, including differing gbOpen licenses, UN OCHA conditions, and the non-commercial restriction on UN SALB data. The functional groundwork came in 0.1.0, which renamed the download functions to object_verb() form, switched the source files from GeoJSON to shapefiles, and added retry handling.
What is tulpa?
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

geobounds
0.0ANALYTICS
geobounds relicensed to MIT and drew a line between its code and the data it downloads.
◆ Current state
geobounds is an R client for the geoBoundaries administrative boundary database. Version 1.0.0 relicensed the package itself from CC BY 4.0 to MIT while documenting that downloaded boundaries keep their own terms, including differing gbOpen licenses, UN OCHA conditions, and the non-commercial restriction on UN SALB data. The functional groundwork came in 0.1.0, which renamed the download functions to object_verb() form, switched the source files from GeoJSON to shapefiles, and added retry handling.
◆ Where it's heading
The package is following rOpenSci conventions closely: the function renaming cited the developer guide directly, and 1.0.0 pairs a permissive code license with explicit, per-source attribution guidance rather than a blanket statement. That distinction matters for a client whose value is entirely in redistributing third-party geodata. Feature work has slowed since 0.1.0 in favor of licensing, documentation, and test isolation.
◆ Prediction
With licensing settled and the API renamed, the next releases most likely track upstream geoBoundaries data releases and boundary coverage rather than changing the interface again.

7.5ANALYTICS
The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.
◆ Current state
tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.
◆ Where it's heading
Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.
◆ Prediction
Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
