FireHydrant vs RSelenium: at a glance
What is FireHydrant?
FireHydrant turns Opsgenie's shutdown into a no-code land grab
FireHydrant is executing on incident management end-to-end while aggressively courting migrations. The June headline is an in-app, no-code Signals Migrator that pulls teams, schedules, and escalation policies out of PagerDuty or Opsgenie and stages them for review before go-live. Around it the platform is maturing on all fronts — a redesigned Teams experience, deeper incident analytics, an EU instance, MS Teams transcription (Scribe), and a long tail of AI-summary and Terraform refinements.
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.

FireHydrant turns Opsgenie's shutdown into a no-code land grab
◆ Current state
FireHydrant is executing on incident management end-to-end while aggressively courting migrations. The June headline is an in-app, no-code Signals Migrator that pulls teams, schedules, and escalation policies out of PagerDuty or Opsgenie and stages them for review before go-live. Around it the platform is maturing on all fronts — a redesigned Teams experience, deeper incident analytics, an EU instance, MS Teams transcription (Scribe), and a long tail of AI-summary and Terraform refinements.
◆ Where it's heading
The strategy is clear: reduce switching cost to near zero and capture responders displaced by Atlassian's Opsgenie wind-down (data deletion set for April 2027). Everything else — EU data residency, MS Teams Scribe, configurable AI conference-bridge summaries — broadens the surface so a migrated team lands on a complete platform, not a thinner alternative. AI runs through the product as summaries and related-incident detection rather than as a standalone feature.
◆ Prediction
With Opsgenie's clock ticking toward 2027, expect FireHydrant to keep hardening the migration path and marketing it hard, while closing feature gaps (Teams parity, EU coverage) a switching customer would notice.
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.
