Cloud · Documentation · Slack · Quickstart

OpenObserve (O2) is a cloud-native observability platform for logs, metrics, traces, analytics, Real User Monitoring (RUM), and AI/LLM observability. It's a cost-effective alternative to Datadog, Splunk, and Elasticsearch for teams that need full observability without the complexity or cost — with Parquet columnar storage and an S3-native design that cuts storage costs by up to 140x.

Product Tour

OpenObserve ships with a powerful, unified web UI for every signal — logs, traces, metrics, dashboards, RUM, alerts, incidents, pipelines, and AI observability.

🏠 Unified Overview

A single home for your workspace — active incidents, service health (error rate, latency, requests), anomalies, and recent events at a glance.

📊 Logs

Centralized log management with full-text search, SQL queries, quick filters, and a visual query builder. Instantly search across all your logs, build dashboards from log data, and set up alerts — all on Parquet columnar storage for 140x lower storage cost than Elasticsearch. Read more →

🔍 Distributed Tracing

Powered by OpenTelemetry, tracing helps you follow requests across services and pinpoint performance bottlenecks. Explore the full request flow with waterfalls, flame graphs, and Gantt charts; click any span to drill into the trace. Read more →

🕸️ Service Graph

Visualize service-to-service dependencies and request flow across your system, with per-edge request counts and health-based coloring (healthy, degraded, warning, critical) to spot problem hotspots at a glance.

📈 Metrics

Explore metrics from your infrastructure and applications, then query them with SQL or PromQL. Browse thousands of metrics with faceted filters, preview them inline, combine multiple queries with formulae, and visualize the results with 19+ chart types. Read more →

📉 Dashboards

Build custom dashboards from any signal with 19+ built-in chart types and 200+ visualization variations, a drag-and-drop panel builder, template variables, and geo maps. Read more →

👀 Frontend Monitoring (RUM)

Real User Monitoring with Core Web Vitals, error tracking, performance analytics, and full session replay — so you can see exactly what your users experience. Read more →

🔔 Alerts

Get notified when something unusual happens on any signal — logs, metrics, or traces. Define thresholds, scheduled or real-time alerts, and notification channels, with alert history and anomaly detection to catch issues early. Read more →

🚨 Incidents

Correlate related alerts into incidents and track them through their lifecycle — open, acknowledged, and resolved — with severity and dimension context for faster response.

🔀 Pipelines

Enrich, redact, reduce, or normalize data at ingest time with a visual editor. Build stream-processing flows — including logs-to-metrics conversion — from source, transform (VRL functions and conditions), and destination nodes. No external tools required. Read more →

🤖 AI Observability

Monitor your GenAI and LLM applications: track cost, tokens, latency percentiles, and error rates across models, with agent graphs, session traces, and evaluation/quality scoring.

✨ O2 AI Assistant

An in-product assistant that writes your SQL, VRL, and PromQL and walks you through logs, traces, metrics, and incidents — turning natural-language questions into queries, dashboards, and alerts.

For the full feature list, see the documentation.

Architecture

OpenObserve achieves 140x lower storage costs and high performance through a modern, cloud-native architecture:

• Parquet columnar storage — efficient compression and fast analytical queries
• S3-native design — inexpensive object storage with intelligent caching
• Built in Rust — memory-safe, high-performance, single binary
• Partitioning, indexing, and smart caching — reduces search space by up to 99% for most queries
• Native multi-tenancy — organizations and streams as first-class concepts with complete data isolation
• Stateless architecture — rapid scaling and low RPO/RTO for disaster recovery

Scale & Deployment

• Thousands of concurrent users can query a single cluster simultaneously
• Single binary scales to terabytes — unique in the observability space
• High Availability mode scales to petabytes for the most demanding workloads
• Multi-region deployments with cluster federation via Super Cluster architecture (Enterprise)
• Federated search across regions and clusters (Enterprise)

High Availability & Disaster Recovery

Deploy in High Availability mode with clustering for mission-critical workloads requiring maximum uptime. OpenObserve's stateless architecture with S3-backed storage enables very low Recovery Point Objective (RPO) and Recovery Time Objective (RTO): stateless nodes restart rapidly, and durability is guaranteed by S3's 99.999999999% (11 nines).

FAQ

How does OpenObserve achieve 140x lower storage costs?

Through a combination of Parquet columnar storage (efficient compression) and an S3-native architecture (inexpensive object storage). See the cost comparison chart in the Why OpenObserve? section.

What are the limitations?

All data in OpenObserve is immutable — once ingested, it cannot be modified or deleted (only entire retention periods can be dropped). This is by design and is a feature for logs and compliance use cases, ensuring data integrity and audit trails.

Is this production-ready?

Yes. OpenObserve runs in production across thousands of deployments worldwide, including environments processing in excess of 2 PB/day. See our customer stories for real-world examples.

How does query performance compare to Elasticsearch?

OpenObserve delivers better performance than Elasticsearch for most workloads, with faster search and significantly faster analytics — while using about a quarter of the hardware. The columnar Parquet format is particularly effective for complex aggregations and analytics.

Is there a steep learning curve?

No. OpenObserve is designed to be intuitive from day one:

• Familiar query languages — SQL for logs and traces, PromQL for metrics; no proprietary query language to learn
• Easy-to-use GUI — an intuitive interface with a drag-and-drop dashboard builder
• No complex tuning — unlike Elasticsearch, there are no shards, replicas, or heap sizes to manage. Just install and go.

Most users are productive within hours, not weeks.
