What Last9 does
Last9 is a cloud-native unified observability platform, founded in 2020 and headquartered in San Francisco with engineering hubs in Mountain View, Pune, and Bengaluru. The platform combines logs, metrics, traces, profiles, real user monitoring, synthetic monitoring, and GPU workload monitoring under a single control plane that routes, transforms, and applies cost controls to telemetry before storage. It is built natively on OpenTelemetry and Prometheus open standards and supports over 100 integrations including Datadog, New Relic, AWS, Azure, GCP, Kubernetes, Kafka, Grafana, and major developer frameworks, enabling customers to migrate from incumbent observability stacks without re-instrumenting code. Underlying the platform is Levitate, a managed time-series data warehouse with tiered storage (Blaze/Hot/Cold) and streaming aggregation, which the company cites as enabling up to 60% TCO reduction versus self-managed Prometheus. The AI layer includes an MCP server, agentic DX for coding agents and SREs, anomaly detection in alerting, and dedicated observability for AI coding tools (Claude Code, Cursor, Codex, Gemini CLI, Cline, goose, GitHub Copilot).
Last9 sells on a usage-based SaaS model (Pro tier at $1,150/month covering 1B events) with no per-seat, per-host, or per-query charges, plus a quote-based Enterprise tier offering custom retention, cardinality quotas, bring-your-own-cloud, and 24x7x365 support. Distribution combines a product-led growth self-serve motion (point existing OpenTelemetry/Prometheus sources to Last9 with minimal configuration, start free, usage-based scaling) with an enterprise field sales motion (dedicated POC and migration support, multi-year commitments). Target buyers are SREs, platform engineers, and engineering leaders at growth-stage and enterprise companies; named customers include Replit, Disney+ Hotstar, CleverTap, Mobile Premier League, Probo, Zoomcar, Tazapay, ToolJet, and Circle, with claimed coverage of 12 of the world's 20 largest streaming companies. The company has raised $13M total ($2M seed in 2020, $11M Series A in 2022 led by Peak XV Partners with Better Capital), holds SOC 2 Type II, ISO 27001, HIPAA, PCI DSS, and GDPR compliance, was named a Gartner Cool Vendor in AI for SRE and Observability in 2025, and carries G2 High Performer, Best Usability, and Highest User Adoption badges with a 4.8/5 rating.

Last9 product offering
Product offeringCore offering
Last9 provides a unified cloud-native observability platform that ingests, correlates, and analyzes high-cardinality telemetry across logs, metrics, traces, and profiles for engineering and SRE teams. The platform includes an AI Control Plane for managing telemetry pipelines, cost controls, and noise reduction before storage, plus an MCP server for agentic developer experience and coding-agent observability. It is delivered as a SaaS subscription (usage-based Pro and custom Enterprise tiers) with OpenTelemetry and Prometheus open-standards compatibility.
Product overview
Last9 is a unified cloud-native observability platform built for high-cardinality telemetry at scale. The core platform, Last9, integrates logs, metrics, traces, and profiles through a unified control plane (Control Plane) that enables route, transform, and cost control before data hits storage. Key modules include Discover (auto-discovery and root cause analysis), Logs, Traces, Metrics, Dashboards, Alerting, SLOs, Real User Monitoring, Synthetic Monitoring, and GPU Workloads monitoring. The platform offers AI-native capabilities through Last9 MCP (Model Context Protocol server) for agentic developer experience and Coding Agent Observability for tracking AI coding agent cost and productivity. Levitate serves as the managed time series data warehouse underpinning the platform with automatic data tiering and cost optimization. The platform is OpenTelemetry-native and Prometheus-compatible, supporting over 100 integrations.

Last9 competitors and assessment
Company assessmentBroad incumbents
- Splunk: Splunk is a broad observability/log analytics incumbent (now part of Cisco). Last9 positions as a cost-efficient OpenTelemetry-native alternative for Splunk migrations, particularly for engineering teams fed up with per-GB ingestion pricing.
- Datadog: Datadog is the dominant broad observability incumbent with a $50B+ market cap. Last9 explicitly positions against Datadog on cost reduction (90% savings claim) and targets Datadog migrations via its Datadog Agent compatibility.
- New Relic: New Relic is a broad APM/observability incumbent with usage-based pricing. Last9 markets directly to New Relic users and offers a one-click migration path for dashboards and alerts—positioning itself as the cost-efficient alternative.
- Dynatrace: Dynatrace is an enterprise observability incumbent with AI-driven automation (Davis AI). Last9 competes for large enterprise observability deals with an AI Control Plane and MCP-based agentic DX narrative.
- Elastic: Elastic Observability is a broad observability offering built on the open-source ELK stack. Both Elastic and Last9 serve log/metric/trace workloads via open-source-adjacent architectures for engineering teams seeking flexibility.
Direct peers
- Grafana Labs: Grafana Labs offers the LGTM stack (Loki, Grafana, Tempo, Mimir) as an open-source-first observability platform. Last9 is Grafana-compatible and competes directly for the same Prometheus/Grafana-native users seeking managed observability with cost controls.
- Chronosphere: Chronosphere is a direct competitor in cloud-native observability with a focus on controlling telemetry costs at scale via its Control Plane. Both companies target the same pain point—exploding observability spend—and compete for the same enterprise SRE/Platform Engineering buyers.
- Coralogix: Coralogix is a direct peer providing full-stack observability with a cost-optimized architecture (similar TCO-reduction narrative). Both target engineering teams seeking alternatives to Splunk/Datadog and emphasize OpenTelemetry compatibility.
- Better Stack: Better Stack offers a unified observability platform combining logs, metrics, and incident management with a strong PLG motion similar to Last9's. Both target developer-led adoption with usage-based pricing.
- Honeycomb.io: Honeycomb is a direct peer offering observability for high-cardinality distributed systems. Both target engineering/SRE teams with tracing, logs, and metrics on a unified platform; Last9 competes head-to-head on high-cardinality workflows and incident triage.
