FireHydrant vs Skipper: 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 Skipper?
Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.

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.

Skipper trims a 4x memory regression out of routesrv, days after shipping h2c
◆ Current state
Zalando's HTTP router ships patch tags almost daily, and most carry a single dependency bump or a one-line auth fix. The substance in this window is v0.27.63, which stops routesrv holding an uncompressed route tree alongside the compressed buffer: retained memory in the release's own benchmark falls from 30.7 MB to 2.0 MB, undoing most of the 4x increase zone-aware routing had introduced. Around it sit narrow auth repairs, and an eskip parser change that finally accepts negative numeric arguments in predicates and filters.
◆ Where it's heading
Two threads run through the recent tags. The data path keeps getting real work - leastRequests balancing, then h2c end to end in v0.27.57, now the memory cost of zone-aware routing being paid back. The auth filters, by contrast, are only being maintained: token introspection, grant auth, and now the OIDC Referer handling are fixes rather than new capability, and several are follow-ups to each other rather than independent bugs.
◆ Prediction
Zone-aware routing looks like the source of the recent memory attention, so expect further tuning around route storage and the hash computation done on every pull, which the release's second benchmark already isolates. The OIDC cookie change is the second link in an auth chain that started with the grant-auth fix, and is likely to draw another follow-up.
