OpenObserve Surpasses 20,000 GitHub Stars as Developers Embrace Open Source Observability

Milestone caps a year of rapid growth for the Rust-based platform, now used by more than 8,000 organizations, including Fortune 100 enterprises ingesting petabytes of telemetry daily

MENLO PARK, Calif.--(BUSINESS WIRE)--OpenObserve, the open source, unified observability platform, today announced that its flagship project has surpassed 20,000 stars on GitHub, placing it among the most popular open source observability projects in the world. The milestone reflects growing developer demand for a simpler and more cost-effective alternative to legacy tools such as Datadog, Splunk, and Elasticsearch.

Built in Rust and deployable as a single binary, OpenObserve consolidates logs, metrics, traces, frontend monitoring, pipelines, and LLM observability into one platform. By storing telemetry in columnar format on low-cost object storage, OpenObserve delivers up to 140x lower storage costs than Elasticsearch, a value proposition that has resonated with engineering teams facing rising telemetry volumes and unpredictable SaaS bills.

"Twenty thousand stars represent tens of thousands of engineers who looked at the status quo in observability and decided there had to be a better way," said Prabhat Sharma, founder and CEO of OpenObserve. "Every star is a developer who believes observability should be open, simple, and affordable at any scale. This community is the foundation of everything we build, and we're just getting started."

Momentum Across the Board

The GitHub milestone follows a period of significant momentum for the company. More than 8,000 organizations now run OpenObserve, including Fortune 100 enterprises that ingest over 2.5 petabytes of telemetry data per day. In May 2026, the company announced a $10 million Series A led by Nexus Venture Partners with participation from Dell Technologies Capital, fueling its vision for Observability 3.0. That vision is already taking shape with recently released capabilities including AI SRE features, anomaly detection, and LLM monitoring for AI-native applications.

OpenObserve is OpenTelemetry-native, supports both SQL and PromQL, and scales horizontally with a stateless architecture, from a laptop to petabyte-scale production clusters, with no vendor lock-in.

Thanks to the Community

OpenObserve extends its gratitude to the contributors, users, and community members worldwide whose issues, pull requests, feedback, and advocacy have carried the project to this milestone. Developers can join the community, star the project, and get started at github.com/openobserve/openobserve.
