Kinsta vs rextendr

Kinsta vs rextendr: at a glance
What is Kinsta?
Kinsta is moving MyKinsta's controls into its API, one surface per month
Kinsta's feed is a blog, so releases arrive as truncated posts, but the pattern underneath is consistent: management surfaces that used to require the MyKinsta dashboard keep reappearing in the Kinsta API. Domains, HTTPS, logs, and backups moved in July; visitor analytics — user agents, browsers, request origins — followed in August. Around that sits a year of bot-traffic work and a file manager in the dashboard, and the newest post extends resilience past backups into a named disaster-recovery offering.
What is rextendr?
rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild
rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.

Kinsta is moving MyKinsta's controls into its API, one surface per month
◆ Current state
Kinsta's feed is a blog, so releases arrive as truncated posts, but the pattern underneath is consistent: management surfaces that used to require the MyKinsta dashboard keep reappearing in the Kinsta API. Domains, HTTPS, logs, and backups moved in July; visitor analytics — user agents, browsers, request origins — followed in August. Around that sits a year of bot-traffic work and a file manager in the dashboard, and the newest post extends resilience past backups into a named disaster-recovery offering.
◆ Where it's heading
The direction is toward WordPress hosting that can be operated entirely programmatically, with MyKinsta as one client among others rather than the control plane. Bot handling and now disaster recovery show the second thread: absorbing operational risk customers would otherwise manage themselves. The blog format hides scope — most posts are teasers — so direction is readable here but the size of any single release is not.
◆ Prediction
Expect the next API release to pick off another MyKinsta-only surface on the same roughly monthly rhythm, with the file manager the obvious candidate. How far disaster recovery goes beyond scheduled backups is the open question these posts do not answer.

rextendr put Rust-backed R packages in the browser, then tore itself down for a 1.0.0 rebuild
◆ Current state
rextendr is the R-side toolchain for extendr, scaffolding and compiling R packages with Rust internals. The package is mid-teardown: the 0.4-final tag in October 2025 warns that main may not work as expected and directs users to install from that tag, and April 2026's release is titled as one more developer release before 1.0.0. Meanwhile the CRAN-facing 0.4.x line did the substantive work.
◆ Where it's heading
Two threads run in parallel. The first is reach: 0.4.0 added WebR support out of the box for all extendr packages by enabling the wasm32-unknown-emscripten target, and 0.4.2 followed with the panic and link-time-optimization settings needed to make those builds actually work. The second is CRAN compliance — use_cran_defaults(), vendor_pkgs(), automatic SystemRequirements fields, and configure scripts, all aimed at getting Rust-powered packages accepted on CRAN. The rebuild announced in 0.4-final is a third thread whose shape the entries do not reveal.
◆ Prediction
The stated destination is 1.0.0 built on the new Makevars-linked build process, so that release is the next milestone. What the revamp changes for existing extendr packages is not described in any entry here.
