campsis vs Cobbler
A side-by-side editorial comparison of campsis and Cobbler — release velocity, themes, recent moves, and the top alternatives to consider.
campsis vs Cobbler: at a glance
What is campsis?
Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.
Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.
What is Cobbler?
A backport branch kept alive for downstreams, with the main line nowhere in sight.
Every release in Cobbler's visible history describes itself the same way: backports from main to make Cobbler more stable for the community. The 3.3.x line has absorbed real work under that framing — collection indices, lazy loading, new XML-RPC endpoints — but none of it originates here. The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.

Campsis breaks its API on purpose: snake_case throughout, RxODE compatibility cut loose.
◆ Current state
Campsis runs clinical-trial simulations from pharmacometric models, sitting on mrgsolve and rxode2 as interchangeable engines, with the sibling package Campsismod supplying the model object layer. Version 1.9.0 is the release where the suite stops carrying its history: the whole API migrates to snake_case, backward compatibility with the old RxODE package is removed, and result processing is refactored into output functions that can be applied as a collection, with an NCA table the first substantial one. Campsismod made the same snake_case move a week earlier, so this is a suite-wide rename rather than one package's decision.
◆ Where it's heading
The 1.8 and 1.9 releases together describe a package being made drivable from outside R. JSON interfaces arrived first for models in Campsismod 1.3.0 and for datasets in Campsis 1.8.0, then extended to scenarios, settings and study replication; the output side has now been generalised the same way, from fixed result processing to a collection of output functions applied to simulated results. Renaming every function and cutting RxODE loose is the cost of that consolidation, paid in one deliberate breaking release rather than spread across several.
◆ Prediction
With the rename and the RxODE removal behind it, the next releases should restore the rxode2 engine to the test suite, which 1.9.0 removed temporarily, and continue filling out the output-function catalogue beyond NCA. The JSON surface looks like the intended entry point for driving Campsis from outside R, though the entries do not say what is meant to consume it.
Cobbler
0.0INFRA · APIS
A backport branch kept alive for downstreams, with the main line nowhere in sight.
◆ Current state

The most recent item is a 3.2.3 build carrying the CVE-2024-47533 fix to an older branch, with its Fixed and Added sections left as literal TBD placeholders.
◆ Where it's heading
This is a stabilization branch serving downstream packagers rather than a product advancing on its own. The work that does land splits cleanly into three buckets: distribution coverage (Ubuntu 22.04, Debian 12, AlmaLinux, RHEL9, openSUSE and SLE signatures), API surface for integrators, and security backports. 3.3.3 flagged dump_vars as the replacement for get_blended_data as of 3.4.0 — a version that has not appeared in any release since.
◆ Prediction
Expect continued single-purpose backports to 3.3.x and older branches as CVEs surface; the entries give no indication of when or whether the 3.4.0 work these releases keep deferring to will ship.
