FireHydrant vs Jaeger
A side-by-side editorial comparison of FireHydrant and Jaeger — release velocity, themes, recent moves, and the top alternatives to consider.
FireHydrant vs Jaeger: at a glance
What is FireHydrant?
FireHydrant stops paging people at night for alerts that can wait until morning.
Support hours now do something during off-hours. Alerts arriving outside a team's window and at or below a new Off-hours Priority Threshold are snoozed, then re-enter the escalation policy from the top when the next window opens. Higher-priority alerts still notify immediately, and a Slack, Teams or webhook destination can report what is queued. The change is opt-in per team until January 2027, when remaining teams are moved over.
What is Jaeger?
Jaeger's query service learns to search individual spans, not just whole traces.
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.

FireHydrant stops paging people at night for alerts that can wait until morning.
◆ Current state
Support hours now do something during off-hours. Alerts arriving outside a team's window and at or below a new Off-hours Priority Threshold are snoozed, then re-enter the escalation policy from the top when the next window opens. Higher-priority alerts still notify immediately, and a Slack, Teams or webhook destination can report what is queued. The change is opt-in per team until January 2027, when remaining teams are moved over.
◆ Where it's heading
The year's table-stakes work for switchers is giving way to on-call quality of life. Schedule overrides made changes safe, and snoozing now reduces unnecessary pages, with visibility built in through a Snoozed filter and alert timelines. The January date makes this the default for everyone, and FireHydrant says it waited until after the holidays so the change does not land in customers' busiest weeks.
◆ Prediction
Expect guidance and prompts pushing teams to set thresholds before the January 2027 switch. API and Terraform coverage for these settings is plausible, but the entry does not mention it.
Jaeger
2.5INFRA · APIS
Jaeger's query service learns to search individual spans, not just whole traces.
◆ Current state
Jaeger 2.21 and 2.22 extend the 2.x storage and query rework. ClickHouse storage moved to a stable feature gate in 2.21, and the release removed v1 HTTP endpoints the UI no longer calls. In 2.22 the query service gains FindSpans with RFC 0014 pagination, Elasticsearch span search, and structured filters promoted to beta, while native Elasticsearch trace summaries go stable.
◆ Where it's heading
The earlier trace-summaries work made search cheaper; span search changes what can be asked. Pagination and structured filters give both the UI and MCP clients a way to query without pulling whole traces. MCP keeps getting practical limits and input checks, and search_traces no longer needs a service name on backends that declare support for that.
◆ Prediction
Expect span search to spread beyond Elasticsearch and memory storage, and structured filters to move from beta to stable as other gates have. Further removal of v1 surface is likely, since 2.21 already started it.
