b3gbi vs gcube
A side-by-side editorial comparison of b3gbi and gcube — release velocity, themes, recent moves, and the top alternatives to consider.

b3gbi vs gcube: at a glance
What is b3gbi?
b3gbi pulled confidence intervals out of its indicator workflow and handed them to dubicube.
b3gbi computes biodiversity indicators from GBIF occurrence cubes for the B-Cubed project, and sits at 0.9.4 in a JOSS review run-up. The 0.9 release decoupled uncertainty from indicator calculation: confidence intervals are no longer produced inline but added afterward with add_ci(), backed by whole-cube bootstrapping from the sibling dubicube package. Everything since has been grid-parsing and compatibility repair around that split.
What is gcube?
gcube's recent releases are all packaging metadata, not simulation code
gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.

◆ Current state
b3gbi computes biodiversity indicators from GBIF occurrence cubes for the B-Cubed project, and sits at 0.9.4 in a JOSS review run-up. The 0.9 release decoupled uncertainty from indicator calculation: confidence intervals are no longer produced inline but added afterward with add_ci(), backed by whole-cube bootstrapping from the sibling dubicube package. Everything since has been grid-parsing and compatibility repair around that split.
◆ Where it's heading
Two forces are shaping releases. Internally, the uncertainty split produced an indicator-specific rule book — species-level indicators bootstrap the whole cube, raw counts resample within year, evenness gets a logit transform — and that rule book is where the statistical thinking now lives. Externally, GBIF's taxonomic backbone migration to the Catalogue of Life forced string taxon keys through process_cube() and the plotting paths, while recurring EEA and MGRS grid-code fixes mark coordinate parsing as the least settled area.
◆ Prediction
The 0.9.4 notes are entirely JOSS review items — contributors, examples, tracked datasets — so the next release is most likely a JOSS-accepted 1.0 rather than new indicator work.

◆ Current state
gcube simulates biodiversity data cubes — generating occurrence points, sampling them under configurable detection bias, and designating them to a grid — as a testbed for the B-Cubed project's indicator tooling. The visible release history is almost entirely metadata and release-automation work: Zenodo grant IDs, ROR URL fixes, publisher fields, funder and rights-holder descriptions. The simulation functionality itself is not what these entries are about.
◆ Where it's heading
The February 2026 cluster reads as a package wiring up its archival identity rather than developing: four releases in four days, one of them explicitly a test of the GitHub release path. That is characteristic of research software preparing to be cited — a Zenodo DOI, correct funder attribution and a checklist-compliant description are the deliverables when the funder requires them. Substantive work on mapping functions and grid designation appears earlier and only through tutorial fixes.
◆ Prediction
With the Zenodo integration and metadata now settled, expect attention to return to the simulation functions themselves, most likely driven by what the sibling indicator packages need to test against.
