About Last9

Last9 provides a unified observability platform that integrates metrics, logs, traces, and APM into a single view, enabling teams to triage issues faster and maintain full visibility without cost explosions. It is designed to be AI-native, offering AI copilots that explain alerts, errors, and traces within existing tools like Slack, Claude, or Cursor. The platform works with existing telemetry sources, eliminating the need for agents or rip-and-replace migrations, and provides granular context by monitoring every user, tenant, and request in full fidelity without dropping labels or sampling data. The platform offers a powerful Control Plane to manage telemetry before storage, allowing users to drop noise, route critical signals, and monitor costs in real-time. It supports high-cardinality visibility, correlating all data types and allowing queries using PromQL, LogQL, TraceQL, or SQL. Last9 also includes user monitoring for frontend and backend correlation, advanced alerting with GitOps support, and one-click migration tools for dashboards and monitors from platforms like Datadog, Grafana, and New Relic. It's built for developers, SREs, and engineering leaders to improve reliability, reduce costs, and accelerate debugging with AI-powered insights and root cause analysis.
