Resend vs RSelenium
A side-by-side editorial comparison of Resend and RSelenium — release velocity, themes, recent moves, and the top alternatives to consider.
Resend vs RSelenium: at a glance
What is Resend?
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
What is RSelenium?
RSelenium's only release in eight years touched documentation and CI, nothing else.
1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018. The releases before it are equally quiet: a dummy argument in `executeScript`, `phantom()` made defunct, and credential-exposure and driver-startup fixes. The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.

◆ Current state
Most recent entries are about who or what can call Resend rather than about email delivery itself: OAuth 2.1 with PKCE, a remote MCP server tracking the current spec, a Codex plugin, a one-click Claude connector, and support for the Agent Plugins Standard. The email product still gets attention — suppressions, template folders, a compatibility checker in the code editor, and now cancellation of scheduled or queued Broadcasts from the API. Entries are terse one-liners, so the shipping cadence reads faster than the surface area actually changing.
◆ Where it's heading
Resend is treating agents as the next class of sending client and building the authorization and discovery plumbing they need before that traffic arrives. The progression is legible: authenticate third parties (OAuth), be callable (MCP), be installable per vendor (Codex, Claude), then be installable by standard. The Cancel Broadcast API is the first sign of the next phase — once non-human callers can schedule sends, the ability to revoke one programmatically stops being a convenience.
◆ Prediction
Authorization and discovery are covered and reversibility has now started; the remaining gap is what an agent is permitted to send in the first place, so scoped per-agent sending limits or approval gates before dispatch are the natural next piece.
RSelenium
0.0INFRA · APIS
RSelenium's only release in eight years touched documentation and CI, nothing else.
◆ Current state
1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018. The releases before it are equally quiet: a dummy argument in `executeScript`, `phantom()` made defunct, and credential-exposure and driver-startup fixes. The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.
◆ Where it's heading
This is a package being kept installable rather than developed. The 2016-2018 era did the architectural work — moving process management out to wdman, recommending Docker for running a Selenium server, retiring PhantomJS — and nothing since has revisited it. That leaves RSelenium sitting on the older WebDriver arrangement while the browser-automation landscape has moved on.
◆ Prediction
Further releases, if any, are likely to be CRAN-compliance rather than feature work; the entries give no indication of active development resuming.
