OpenAnalytics is an open-source, self-hostable web analytics stack developed by OpenLabs. It uses a lightweight browser tracker without cookies, fingerprinting, or cross-site profiles, and provides aggregate-only analytics for page views, custom events, sessions, web vitals, funnels, retention, embeddable widgets, public sharing, live presence, and Stripe revenue attribution. The repository is a pnpm monorepo comprising a tracker, ingestion collector, queue worker, API, ClickHouse query gateway, realtime SSE service, Next.js dashboard, and CLI. Postgres stores control-plane data, ClickHouse stores events and rollups, and Valkey provides the event queue and realtime cache. The query gateway is the only component permitted to read ClickHouse and verifies Ed25519-signed query envelopes; visitor identity uses a salted hash that rotates nightly, while optional city-level geolocation is resolved against a database on the host. It also includes CSV/JSON import and export, an MCP server, and an AI assistant. The project is licensed under AGPL-3.0. It can be self-hosted with Docker Compose, or used through the authors' hosted instance at getopen.so. Release images are published to GitHub Container Registry.

OpenObserve is an open-source, self-hosted observability platform for logs, metrics, traces, dashboards, frontend monitoring, pipelines, and incidents. It accepts OpenTelemetry data and provides SQL queries for logs and traces and SQL or PromQL queries for metrics. The platform is built in Rust and supports single-binary deployment, using Parquet columnar storage with an S3-native architecture; it also offers a unified web interface and cloud-hosted edition.

OpenTelemetry is an open-source, vendor-neutral observability framework for cloud-native software. It provides APIs, SDKs, automatic-instrumentation agents, and collector services for capturing distributed traces, metrics, logs, and contextual metadata such as baggage. Its context-propagation mechanism correlates telemetry across service boundaries and carries trace identity through an application’s request path, including standard HTTP communication. The OpenTelemetry Collector receives, processes, filters, and routes telemetry to observability backends such as Jaeger, Prometheus, commercial systems, or custom solutions. It supports native SDKs for more than 12 languages and is hosted as a graduated project by the Cloud Native Computing Foundation.

Grafana is an open-source observability and data visualization platform for querying, visualizing, alerting on, and understanding metrics, logs, and traces from multiple data sources. It provides client-side graphs and panel plugins, reusable dashboards with template variables, ad hoc metric queries and drilldowns, log search with preserved label filters, and alert rules that can send notifications to systems such as Slack, PagerDuty, VictorOps, and OpsGenie. Queries can combine different data sources in the same graph, including Prometheus, Loki, Elasticsearch, InfluxDB, PostgreSQL, and other custom data sources. The project is distributed under AGPL-3.0-only, with Apache-2.0 exceptions documented in its licensing files.

Loki is an open-source log aggregation system developed by Grafana Labs that indexes and queries logs using Prometheus-style labels instead of full-text indexing. It ingests log streams via shippers such as Promtail, Fluentd, or other collectors, stores data in local or object-storage backends, and is queried with the LogQL language; it integrates with Grafana for visualization and is available for self-hosting or via Grafana Cloud.
