Last9
AI-native observability platform unifying metrics, logs, and traces for high-cardinality data.
About
Last9 is an observability platform built for high-cardinality telemetry, unifying metrics, logs, traces, real user monitoring, and alerting in one place. It is OpenTelemetry-native and Prometheus-compatible, keeps high-cardinality labels queryable at scale, and runs single-tenant inside the customer's own AWS or GCP account.
Its AI capabilities work in both directions: an assistant, an MCP server, and an alert-investigating agent available in the app, Slack, and the IDE, plus dedicated LLM and agent monitoring for teams shipping their own AI products. A Control Plane lets teams drop, aggregate, and reshape telemetry before storage to control costs.
What it can do
- Unified metrics, logs, traces, RUM, and alerting with PromQL and LogQL
- AI assistant, MCP server, and alert-investigating agent in app, Slack, and IDE
- Control Plane for pre-ingestion telemetry shaping and cost control
- LLM and AI agent monitoring alongside traditional observability
Setup
Sign up on last9.io, then send telemetry via OpenTelemetry SDKs, the OTel Collector, or Prometheus remote write. Choose SaaS or bring-your-own-cloud deployment.
Prerequisites
Instrumented services emitting OpenTelemetry or Prometheus telemetry; an AWS or GCP account for the single-tenant deployment option.
