ArchR vs silx
A side-by-side editorial comparison of ArchR and silx — release velocity, themes, recent moves, and the top alternatives to consider.
ArchR vs silx: at a glance
What is ArchR?
ArchR returns after three years, mostly to catch up with the ecosystem around it.
ArchR analyses single-cell chromatin accessibility data, and until early 2025 its last release was from 2022. Release 1.0.3 collects roughly three years of accumulated pull requests: ggplot2 3.5 compatibility, Seurat v5 object creation, large-matrix handling via ARMA_64BIT_WORD, trajectory and module-score work, and a published Docker image. The release candidate before it did nothing but lift a 500 MB import ceiling.
What is silx?
silx settles into maintenance a release after its PySide6 migration
silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.

ArchR returns after three years, mostly to catch up with the ecosystem around it.
◆ Current state
ArchR analyses single-cell chromatin accessibility data, and until early 2025 its last release was from 2022. Release 1.0.3 collects roughly three years of accumulated pull requests: ggplot2 3.5 compatibility, Seurat v5 object creation, large-matrix handling via ARMA_64BIT_WORD, trajectory and module-score work, and a published Docker image. The release candidate before it did nothing but lift a 500 MB import ceiling.
◆ Where it's heading
This is a maintenance restart rather than a new direction. The contributor list shifts visibly from the original authors toward newer maintainers handling compatibility work, and the Docker image suggests an acknowledgement that reproducing the environment had become the harder problem. Whether the cadence recovers is not something these entries answer.
◆ Prediction
The entries do not support a confident call on future direction; the immediate question is whether releases resume at a normal interval or 1.0.3 was a one-off catch-up.

silx settles into maintenance a release after its PySide6 migration
◆ Current state
silx is in the quiet phase after a generational release. 3.1.1 is a single fix to FitWidget loading a fit function from file. The release before it, 3.1.0, was the first real feature work since the migration - asinh axis scaling, twilight colormaps, and dark-theme icons - and 3.0.1 was similarly small. The 3.0.0 cut that reset the Qt binding and Python floor still defines what the line is doing.
◆ Where it's heading
The cadence has slowed markedly since April, and the content has shifted from structural change to plotting and colormap refinement. That is the expected shape after a binding migration: downstream beamline code needs a stable target, so the project trades feature velocity for a quiet surface. The gap between 3.0.1 in May and 3.1.0 in August is the clearest signal of the deliberate slowdown.
◆ Prediction
Expect further point releases servicing the plotting and fitting widgets rather than another structural change, with feature work continuing to arrive in the 3.1.x minors rather than patches.
