What is downlit?

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

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.

downlit's HTML contract was set in 0.4.0; every release since tracks R itself.

◆ Current state

downlit does syntax highlighting and automatic linking of R code to documentation, and is the engine behind pkgdown's code blocks. Version 0.4.0 restructured its output into the class taxonomy themes style against, and 0.4.1 completed it with base pipe support and per-line spans. The three releases since are compatibility fixes for R and R-devel.

◆ Where it's heading

The package reached its intended shape in the 0.4.x pair and has been static since. Its work now is reacting to the language and toolchain: a new pipe operator to highlight, an R-devel change to survive, a UTF-8 parsing crash routed around by simplifying the algorithm. Autolinking coverage, which drew steady contributions through 0.4.1, has not been extended since 2022.

◆ Prediction

Expect the next release to track another R or pandoc change rather than extend highlighting or linking.

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.
