httr vs httr2
A side-by-side editorial comparison of httr and httr2 — release velocity, themes, recent moves, and the top alternatives to consider.
httr vs httr2: at a glance
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.
What is httr2?
httr2 is growing production concerns: tracing, throttling and token hygiene.
httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.

◆ 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.
httr2
2.5DEVOPS
httr2 is growing production concerns: tracing, throttling and token hygiene.
◆ Current state
httr2 is the tidyverse's modern HTTP client and the designated successor to httr. Recent releases have moved past request-building ergonomics into operational concerns — OpenTelemetry traces for every request, throttling that behaves correctly across repeated calls, and a fix for OAuth token caches that were never actually being pruned.
◆ Where it's heading
The package is maturing into infrastructure for long-running R services rather than interactive scripts. The 1.2.0 lifecycle purge removed deprecated streaming and mocking APIs in favour of a connection-based model, and debugging affordances like httr2_translate() point at users who need to reproduce a failing request outside R.
◆ Prediction
Expect further observability and credential-handling work, with the rlang-driven cache hash change in 1.3.0 likely to surface follow-up issues as existing caches silently invalidate.
