What is Jaeger?
Jaeger folds its MCP server into the query service and drops Elasticsearch 6
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.
What is SigNoz?
SigNoz is turning observability data into a native input for AI coding agents.
SigNoz is shipping on multiple fronts: alert routing integrations (incident.io, Jira, JSM), Kubernetes visibility depth (Containers view, instrumentation scope queries), and dashboard access controls. The most distinctive thread is the Agent Skills plugin (Aug 26), which makes SigNoz data accessible from AI coding environments like Claude Code and Cursor without leaving the editor.

Jaeger folds its MCP server into the query service and drops Elasticsearch 6
◆ Current state
Jaeger's 2.x line is releasing roughly monthly, and two threads dominate. The storage layer is being modernised and pruned — Elasticsearch 6 support removed, rotation and index-cleaner feature gates promoted to beta, ClickHouse gaining TLS and analyzer fixes, configurable max trace duration. The other thread is the query surface: a lightweight trace-summaries endpoint added in 2.19 then given a native Elasticsearch implementation in 2.20, and the MCP extension merged into the query extension.
◆ Where it's heading
Jaeger is treating machine consumption of traces as a first-class query path rather than an add-on. Merging jaegermcp into jaegerquery means the MCP surface ships wherever query ships, and trace summaries give both the UI and any agent a cheap way to scan results before pulling full traces. On storage, the direction is fewer supported backends maintained better, with ClickHouse steadily gaining parity.
◆ Prediction
Expect the trace-summaries path to become the default for search across storage backends, and further ClickHouse feature work as the Elasticsearch surface is trimmed rather than extended.
SigNoz
6.3INFRA · APIS
SigNoz is turning observability data into a native input for AI coding agents.
◆ Current state
SigNoz is shipping on multiple fronts: alert routing integrations (incident.io, Jira, JSM), Kubernetes visibility depth (Containers view, instrumentation scope queries), and dashboard access controls. The most distinctive thread is the Agent Skills plugin (Aug 26), which makes SigNoz data accessible from AI coding environments like Claude Code and Cursor without leaving the editor.
◆ Where it's heading
The product is building a coherent agent-native observability platform. The Agent Skills plugin, the agentic dashboard schema (Jul 29 Perses-based rebuild), and the AI cost investigation skill (Jul 22) form a pattern: SigNoz is positioning itself as the observability layer that AI agents query and act on, not just a UI for human operators. Conventional alerting and dashboard features are being fleshed out in parallel, but the agentic access layer is the differentiating direction.
◆ Prediction
Deeper query skills for specific telemetry types — per-service metrics, trace analysis — are the likely next step, tightening the integration between agent coding workflows and live observability data.
