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 waldo?

waldo keeps shedding dependencies while teaching its diff engine new object systems

waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.

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.

waldo keeps shedding dependencies while teaching its diff engine new object systems

◆ Current state

waldo produces the object comparisons that testthat failure messages are built from. The recent releases do two things: drop dependencies - tibble, rematch2 and fansi have all gone - and extend comparison to object systems that did not exist when it was written, notably S7. Correctness of missing-value and tolerance semantics accounts for most of the rest.

◆ Where it's heading

This is a package deliberately shrinking its footprint while widening what it understands. Since it is imported by testthat, every dependency it drops is one fewer package in the check environment of most of CRAN, which is clearly the motivation. The comparison logic itself changes only when R gains a new way to represent objects.

◆ Prediction

Expect S7 support to deepen from basic to complete as S7 adoption grows, and further dependency removals; the diff algorithm itself looks settled.
