StarTree

StarTree is a real-time analytics platform built on Apache Pinot, the open-source OLAP database for user-facing and agent-facing analytics. StarTree Cloud is the fully managed, enterprise-grade service — sub-second queries at high concurrency, streaming and batch ingestion up to millions of events per second, scalable upserts, in-place queries on Apache Iceberg tables, and ThirdEye anomaly detection. It ships enterprise security (RBAC, SSO, encryption, SOC 2 / ISO 27001 / HIPAA) with SaaS, BYOC, and BYOK deployment options, and exposes Controller, Broker, and Query REST APIs plus an official MCP server for agents.

StarTree publishes 1 API on the APIs.io network: Query API API. Tagged areas include Company, Data, Analytics, Real-Time Analytics, and OLAP.

StarTree’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 21 more developer resources.
