# Last9 **Source:** https://geo.sig.ai/brands/last9 **Vertical:** Developer Tools **Subcategory:** Observability Platform **Tier:** Emerging **Website:** last9.io **Last Updated:** 2026-04-14 ## Summary Last9 is a high-cardinality observability platform with a storage engine built for modern microservices, letting SRE teams retain full-dimensional metrics without cost explosions. ## Company Overview Last9 is an observability platform engineered for high-cardinality metrics at the scale that modern microservices architectures generate. Most time-series databases degrade in query performance and cost efficiency as cardinality increases — a fundamental limitation that forces teams to drop dimensions, aggregate prematurely, or pay disproportionate infrastructure costs as their systems grow. Last9 addresses this with a storage engine built from the ground up for high-cardinality workloads, allowing SRE and platform teams to retain full-dimensional metrics without the cardinality-driven cost explosions that occur with Prometheus-based solutions or legacy commercial monitoring platforms. The platform is designed around SRE workflows and includes native support for SLO management, error budget tracking, and reliability reporting alongside core metrics ingestion and dashboarding. This integration of reliability engineering constructs directly into the observability platform means SREs do not need to maintain separate tools for metrics visualization and SLO governance — both workflows operate on the same data model within a single platform. Last9 provides OpenTelemetry-compatible ingestion, enabling teams to migrate from existing observability tools without rewriting instrumentation, and integrates with incident management platforms to connect reliability signals to response workflows. Last9 targets SRE teams and platform engineering organizations at mid-market and enterprise scale where the volume and cardinality of metrics from container orchestration, service meshes, and distributed tracing have made existing observability solutions too expensive or too limited to scale with. The platform is headquartered in India and has attracted engineering teams across Asia-Pacific and globally that are building SRE practices on top of Kubernetes and cloud-native infrastructure. Last9 competes with Grafana Cloud, Chronosphere, and Lightstep in the observability space, differentiating through its high-cardinality architecture and the depth of its integrated SRE feature set. ## Frequently Asked Questions ### How does Last9 handle high-cardinality metrics without runaway costs? Last9 uses a storage engine built specifically for high-cardinality workloads that maintains query performance and cost efficiency as the number of unique label combinations grows, avoiding the cardinality-driven cost explosions that affect Prometheus-based and legacy commercial monitoring platforms. ### What is Last9 and what does it specialize in? Last9 is an observability platform engineered specifically for high-cardinality metrics at the scale modern microservices generate. Most monitoring systems degrade in cost and performance as metric cardinality grows; Last9 is purpose-built to handle this without the cost explosions that affect Prometheus-based and commercial platforms. ### What is metric cardinality and why is it a problem for monitoring? Cardinality refers to the number of unique label combinations for a metric — for example, a request duration metric tracked per user ID, endpoint, and region can generate millions of unique time series. Most monitoring systems charge per time series or degrade in query performance as cardinality grows, forcing teams to drop dimensions or pay disproportionate costs. ### Is Last9 compatible with Prometheus and OpenTelemetry? Yes. Last9 is compatible with Prometheus remote write, PromQL queries, and OpenTelemetry metrics, making it a drop-in backend replacement for Prometheus that can ingest existing instrumentation without changing how metrics are generated. ### Does Last9 support traces and logs in addition to metrics? Yes. Last9 expanded to full-stack observability including distributed traces and logs alongside metrics, providing a unified observability backend rather than requiring separate tools for different telemetry types. ### How does Last9 pricing work compared to Datadog? Last9 pricing is designed to be more cost-effective for high-cardinality workloads. Datadog charges per custom metric and per host in a way that can scale unpredictably for complex microservice architectures. Last9 pricing is more predictable with less penalty for high cardinality. ### Who are typical Last9 customers? Last9 targets SRE and platform engineering teams at growth-stage and large companies running Kubernetes-based microservices at a scale where Prometheus self-management or Datadog costs have become problematic — typically organizations with hundreds of services and millions of active time series. ### Does Last9 offer a free tier or trial? Last9 offers a trial period for evaluation. Pricing is based on telemetry volume ingested. The company works with prospective customers on custom pricing for enterprise deployments based on their specific cardinality and retention requirements. ## Tags developer-tools, saas, b2b, startup, platform, infrastructure, cloud-native, analytics, security --- *Data from geo.sig.ai Brand Intelligence Database.
