plumber vs uproot5
A side-by-side editorial comparison of plumber and uproot5 — release velocity, themes, recent moves, and the top alternatives to consider.
plumber vs uproot5: at a glance
What is plumber?
R's API framework grew its serializer catalogue, then went quiet on features.
plumber is at 1.3.3, and the last three releases are small: a Swagger redirect fix for hosted environments, a test-robustness change, and Arrow IPC Streams serializers. The feature weight sits further back — 1.3.0 added excel serializers and parsers, ragg and svglite graphics devices, port validation against IANA ranges, and stopped writing parsed bodies to disk.
What is uproot5?
Uproot quietly made RNTuple the default write format — filed under 'chore'.
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.

R's API framework grew its serializer catalogue, then went quiet on features.
◆ Current state
plumber is at 1.3.3, and the last three releases are small: a Swagger redirect fix for hosted environments, a test-robustness change, and Arrow IPC Streams serializers. The feature weight sits further back — 1.3.0 added excel serializers and parsers, ragg and svglite graphics devices, port validation against IANA ranges, and stopped writing parsed bodies to disk.
◆ Where it's heading
The pattern across the window is a framework extending what it can exchange rather than what it can do. GeoJSON and parquet in 1.2.0, excel in 1.3.0, Arrow IPC Streams in 1.3.1 — each release adds a format, while routing, OpenAPI and the annotation model stay where 1.1.0 left them. The recent tags suggest that expansion has slowed to hosting-compatibility fixes.
◆ Prediction
Given three consecutive small releases and no open feature thread in the notes, the next version most likely continues as a maintenance patch rather than adding another serializer family.

Uproot quietly made RNTuple the default write format — filed under 'chore'.
◆ Current state
Uproot ships small, frequent 5.7.x releases in which the RNTuple work dominates and is often buried below the feature list. Since switching the default write format to RNTuple in 5.7.0, the releases have been about making that path complete: entry bounds and report=True for RNTuple.iterate, GPU interpretation of RNTuple data with nvCOMP decompression, support for the v1.0.1.0 format, and the library kwarg finished. Two of the six releases in this window list no new features at all.
◆ Where it's heading
This is a migration project wearing patch-release clothing. The direction is that RNTuple, ROOT's newer columnar format, becomes what Uproot writes and reads by default, with the older TTree path maintained rather than developed. The GPU decompression work points further out: reading physics data straight into accelerator memory rather than staging it through the CPU. Expect the remaining gaps to keep surfacing as bug fixes in the RNTuple path as more of the field writes in the new format.
◆ Prediction
Continued 5.7.x patches closing RNTuple feature parity with TTree, with the GPU and nvCOMP path the most likely area to gain rather than just get fixed.
