Amundsen vs OpenMC
A side-by-side editorial comparison of Amundsen and OpenMC — release velocity, themes, recent moves, and the top alternatives to consider.
Amundsen vs OpenMC: at a glance
What is Amundsen?
Amundsen's last release was a config flag, and the feed has been silent for two years
Amundsen ships as several separately versioned components — databuilder, metadata, frontend, common — cut from one repository, and the release feed shows the same changelog republished under three different component tags on the same afternoon. Reading past the tag names, the content is overwhelmingly dependabot bumps, Python compatibility-matrix maintenance and mypy upgrades, with real features appearing a couple of times a year. The final release, databuilder 7.5.1 in August 2024, contains exactly one change: a config option for implicit transactions in the neo4j extractor.
What is OpenMC?
OpenMC's random ray solver has gone from new arrival to the centre of every release
OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.

Amundsen's last release was a config flag, and the feed has been silent for two years
◆ Current state
Amundsen ships as several separately versioned components — databuilder, metadata, frontend, common — cut from one repository, and the release feed shows the same changelog republished under three different component tags on the same afternoon. Reading past the tag names, the content is overwhelmingly dependabot bumps, Python compatibility-matrix maintenance and mypy upgrades, with real features appearing a couple of times a year. The final release, databuilder 7.5.1 in August 2024, contains exactly one change: a config option for implicit transactions in the neo4j extractor.
◆ Where it's heading
The direction is contraction. Python 3.7 support was dropped and the matrix narrowed to 3.8 and 3.9 before 3.10 was cautiously added to everything except the metadata service, contributor names moved to emeritus status, and organisations were removed from the README's adopter list. What feature work exists is small and peripheral — a PowerBI logo, aggregated alerts, a gremlin proxy method — rather than anything touching how the catalog works. Nothing has been published since August 2024.
◆ Prediction
There is no signal in these entries of planned work, and a two-year silence following a single-flag release means the practical expectation is no further releases; the component version skew across databuilder, metadata and frontend is now frozen where it stopped.

2.5ANALYTICS
OpenMC's random ray solver has gone from new arrival to the centre of every release
◆ Current state
OpenMC is a Monte Carlo particle transport code for neutronics and radiation analysis. Since the random ray transport solver landed in 0.15.0 it has received substantial work in every subsequent release, most recently local adjoint sources, temperature and distributed-density feedback, fission-heating tallies and a weight-window bootstrapping workflow. The other consistent thread is shutdown-dose and depletion tooling, where 0.15.3 introduced an R2SManager to automate the rigorous two-step workflow and 0.16.0 extended it with reactivity control, CRAM substeps and multiple meshes.
◆ Where it's heading
The project is layering a deterministic-adjacent solver alongside its Monte Carlo core rather than replacing it, and the ratio of random-ray work to core-solver work in each release keeps rising. In parallel it is packaging expert workflows into objects — R2SManager is the clearest case, turning a multi-stage shutdown dose calculation into a class rather than a recipe. The Python API is where most of that packaging surfaces, and it is also where the compatibility breaks land, with the minimum version moving to 3.12 in 0.16.0.
◆ Prediction
Given that every release since 0.15.0 has expanded the random ray solver's feedback and tally coverage, the next is likely to continue closing the gap between it and the main solver's feature set. The notes do not indicate whether it is intended to become a default path.
