httpuv vs httr: at a glance
What is httpuv?
httpuv ships almost nothing, which is what you want from the web server under Shiny
httpuv is the C++ HTTP and WebSocket server that Shiny runs on. Across this window it added exactly one user-facing function - runStaticServer() for serving a directory - and spent every other release on race conditions, compiler and linker changes, CRAN check warnings, and mime type table updates.
What is httr?
httr's last releases are housekeeping - the package now points users at httr2
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.

httpuv ships almost nothing, which is what you want from the web server under Shiny
◆ Current state
httpuv is the C++ HTTP and WebSocket server that Shiny runs on. Across this window it added exactly one user-facing function - runStaticServer() for serving a directory - and spent every other release on race conditions, compiler and linker changes, CRAN check warnings, and mime type table updates.
◆ Where it's heading
There is no direction here in the usual sense, and that is the honest read: the package is a stable foundation whose releases are triggered by the toolchain moving, by R-devel warnings, or by a threading bug surfacing under load. The one recurring theme with substance is connection reliability - WebSocket keepalive pings, race conditions in the I/O thread - which is what actually breaks Shiny apps in production.
◆ Prediction
Expect continued small releases tracking Rtools, R-devel and mime data, with any substantive change most likely coming from a threading or WebSocket issue reported by Shiny users rather than from planned work.
httr

httr's last releases are housekeeping - the package now points users at httr2
◆ Current state
httr is in wind-down. The last release with real feature work was 1.4.0 in 2018; everything since is test stabilization, CRAN-driven fixes, and unwinding a dependency on the httpbin service. Version 1.4.7 removed the vignette contents outright and redirects readers to httr2.
◆ Where it's heading
This is a succession, not a decline. The maintainers are keeping httr installable and passing checks for the very large base of packages that depend on it, while all design work happens in httr2. The pattern across these six releases is unambiguous: nothing lands here unless CRAN, a test service, or a platform forced it.
◆ Prediction
Expect continued patch releases driven only by CRAN checks and toolchain changes; the interesting HTTP work in R will keep landing in httr2.
