chromote vs pkgbuild
A side-by-side editorial comparison of chromote and pkgbuild — release velocity, themes, recent moves, and the top alternatives to consider.
chromote vs pkgbuild: at a glance
What is chromote?
chromote turned the browser itself into a pinned, downloadable dependency.
chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.
What is pkgbuild?
A package whose release calendar is written by whoever ships the next Rtools.
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.

chromote turned the browser itself into a pinned, downloadable dependency.
◆ Current state
chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.
◆ Where it's heading
The package has moved from reacting to Chrome upgrades to controlling them. The 0.3.0 and 0.4.0 pair tracked the headless-mode transition by first adding an option and then flipping the default; 0.5.0 removed the need to track it at all by managing versioned binaries through Chrome for Testing. Alongside that, the session API keeps accumulating helpers that collapse multi-step DevTools call sequences, such as $go_to() and $set_viewport_size().
◆ Prediction
The version-management features shipped marked experimental, so the likely next step is stabilizing that API and extending the session helpers that wrap common DevTools sequences.
pkgbuild
0.0INFRA · APIS
A package whose release calendar is written by whoever ships the next Rtools.
◆ Current state
pkgbuild is the layer devtools and pak use to run R CMD build and R CMD INSTALL, and most of what it does is know where the compiler is. Six of its last eight releases are about Rtools: supporting Rtools43, 44 and 45, finding installations that did not come from an installer, reading the Windows registry correctly again, and handling aarch64 Windows when the expected environment variable is unset. The feature surface is a handful of Config/build/* DESCRIPTION options for packages with unusual build needs.
◆ Where it's heading
This is maintenance defined entirely by other people's release schedules — R minor versions, Rtools versions, and the DESCRIPTION options downstream package authors ask for. The one structural change worth noting is that on R 4.3 and later the package stopped special-casing Windows and now tests for build tools by compiling a small package, the same way it always has on Unix. That is the direction: fewer platform branches, more probing.
◆ Prediction
Expect the next release to add support for whichever Rtools ships alongside the next R minor version, and expect the Windows registry lookups to keep shrinking as the compile-probe approach proves out.
