Open Source Analytics Apps

Open-source AI observability platform for tracing, evaluating, and debugging LLM applications with built-in intelligence and MCP support.

The all-in-one open source product platform combining analytics, session replay, feature flags, error tracking, AI observability, and a built-in data warehouse in a single self-hostable stack.

Self-host your entire observability stack — logs, metrics, traces, and LLM monitoring — in one OpenTelemetry-native platform, without the Datadog bill.

Self-hosted uptime and infrastructure monitoring with multi-protocol checks, global geo-coverage, and beautiful real-time dashboards.

Turn SQL queries and markdown files into polished, interactive data apps and business intelligence reports — no drag-and-drop, no GUI, just code.

Self-hosted session replay and product analytics suite that lets you see exactly what users do on your web app — without sending data to third parties.

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.

Redash lets anyone connect to 35+ SQL and NoSQL data sources, write a query in the browser, and turn the result into a shared dashboard — no separate BI suite required.

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.

Self-hosted WakaTime-compatible coding statistics backend that gives developers full control over their coding activity data.

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

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.
