Trace anything, fast.
It's all correlated and queryable. Switch between logs, traces and metrics in one click. Query however you prefer—you're in control.
Data Insights at scale
Triage smarter, faster and remediate across your stack with AI. Last9 makes sense of noisy telemetry data for the whole team.
Last9 platform use cases
Control plane
A single control plane to manage telemetry pipelines across logs, metrics, and traces — route, transform, and apply cost controls before data hits storage.
Agentic DX
An AI-native developer experience with an MCP server, so coding agents and SREs can query telemetry, triage incidents, and remediate issues directly from their IDE or chat.
Logs & traces
Correlated logs and distributed traces with full OpenTelemetry support — jump from a slow span to the exact log lines that explain it, with no sampling on errors.
Dashboards
High-cardinality dashboards backed by a Prometheus-compatible query engine — slice by any label without pre-aggregation, and share views across teams.
User monitoring
Real user monitoring (RUM) for web and mobile — capture Core Web Vitals, session replays, and frontend errors, then correlate them with backend traces.
Alerting
Real-time alerting with deduplication, routing, and on-call integrations — define rules in PromQL or our UI and send to Slack, PagerDuty, OpsGenie, and more.
An adaptable platform that works for you
High cardinality data optimized for AI. Complete control over costs. Last9 adapts to the way you work—it's the only observability solution you'll ever need.

Last9 platform features
Unified, high-cardinality observability.
Track database calls, deployments and user flows in real time. Even at 20M+ cardinality per metric.
Fine-tune telemetry before it hits storage.
Drop noise, route critical signals, and monitor costs in real time without black boxes.
Unified observability made fun & easy
It's embarrassingly simple to get actionable insights from your data. Just plug in existing sources to get alerts and see correlated metrics, logs and traces on a single pane.
How Last9 unifies your telemetry
Last9 ingests every telemetry signal — metrics, logs, traces, and profiles — and routes them through an AI Control Plane, Context Store, and Unified Telemetry layer to power three outputs: dashboards, alerts, and AI agents.
- Inputs: Metrics, Logs, Traces, Profiles
- Processing: AI Control Plane, Context Store, Unified Telemetry
- Outputs: Dashboards, Alerts, AI agents
AI-native triage.
Plug in to Claude, Cursor or Slack and let AI co-pilots explain alerts, errors and traces.
Use your own stack.
No agents. No rip-and-replace. Just point your existing telemetry sources to Last9.
Granular context.
Monitor every request, tenant and user in full fidelity. Never drop labels or sample data again.
Minutes to value.
Start with one config. Last9 auto-detects services and instantly generates dashboards.
