Distributed SQL database for real-time analytics at scale

Open-source column-oriented database that delivers real-time analytical queries on petabyte-scale data with millisecond latency.

Open-source metadata platform that unifies data catalog, lineage, quality, and governance into a single searchable graph, with an MCP server that gives AI agents governed access to that context.

A high-performance, open-source time-series database built for financial market data, IoT telemetry, and real-time analytics, combining a zero-GC Java/C++ core with SIMD-accelerated SQL and a WAL-to-Parquet storage engine.

Open-source GenBI engine that lets AI agents turn natural-language questions into governed SQL, charts, and shareable dashboards across 20+ data sources — no vendor lock-in, no black-box prompts.

eBPF-powered observability with AI root cause analysis — zero code changes required, full-stack visibility out of the box.

The fastest BI tool for humans and agents — define metrics, models, and dashboards as code and query them instantly on ClickHouse or DuckDB.

Single C++ binary SQL engine for real-time stream processing, ETL, and analytics on Kafka, Redpanda, and ClickHouse with sub-millisecond latency.

Replace Google Analytics, UptimeKuma, and Prometheus with one self-hosted platform that tracks websites, monitors uptime, and reports server health.

The dbt-native data observability CLI that turns your existing dbt tests and metadata into anomaly detection, lineage graphs, and Slack/Teams alerts — no separate platform required.

Build and deploy an open-source analytics agent that understands your data warehouse and answers business questions in plain English.

Open-source time-series database built for real-time ingest, fast SQL queries, and embedded Python automation — powered by Apache Arrow and Parquet.

Build analytics dashboards, reports, and customer-facing analytics by writing pure SQL — powered by DuckDB and designed for self-hosted deployment.

A self-hosted Rust PaaS that replaces Vercel, Sentry, PostHog, Pingdom, Resend, and E2B with one binary — plus 440+ CLI operations agents like Claude Code can drive directly.

A pretrained decoder-only foundation model by Google Research that delivers zero-shot time series forecasting with calibrated quantile prediction intervals — no training required.

ktx builds a self-improving context layer over your data warehouse so AI agents like Claude Code and Codex query it with approved metric definitions instead of reinventing SQL logic from scratch.

An open-source AI gateway and LLM observability platform that routes requests to 100+ models while logging cost, latency, and full traces for every call.

Open-source business intelligence platform with drag-and-drop dashboards, multi-source SQL connectors, and Kubernetes-ready deployment built by Yandex.

A visual and textual programming platform for data prep and analysis where the node graph and the underlying Enso code are always perfectly in sync, built by an Alteryx co-founder on a GraalVM engine.

Cookie-free, AI-powered web analytics you can self-host in 30 seconds with Docker.
