Show HN: Open-source and AI native web analytics

OpenLabs-so released OpenAnalytics, an open-source, AI-native web analytics platform self-hostable under AGPL-3.0, featuring a lightweight tracker, ClickHouse-based storage, and an AI assistant, with a hosted instance at getopen.so. The monorepo includes apps for tracking, collection, querying, and a dashboard, and supports page views, funnels, revenue analytics, and an MCP server. Self-hosting requires a Linux host with Docker, four DNS records, and about 4 GB of RAM, with installation via a single docker compose command.

Open-source, privacy-first web analytics. One lightweight tracker script, no cookies, no cross-site profiles, aggregate-only reads — self-hostable on your own hardware under AGPL-3.0. A hosted instance runs at getopen.so , operated by the authors: the same code, someone else's servers. ▶ Watch the dashboard in motion , a tour of these same screens on YouTube.

What it does, in one list: page views, custom and attribute-driven events, sessions, web vitals, funnels, per-site retention, embeddable widgets, public share links, revenue analytics from your Stripe account, CSV/JSON import and export, an MCP server, and a CLI. Who is on the site now , from a presence cache rather than a table scan. Names are generated per visitor and mean nothing outside the day they were minted. Where one visitor went , session by session. The identity behind a trail is a salted hash that rotates every night, so the trail is as long as a visit and never as long as a person. Where they are , at city level and only when a site opts in. The lookup runs against a database on your own disk and never leaves the host. Architecture rules CI enforces, not conventions: apps/web may import only packages/contracts — the OpenAPI document is the single seam between frontend and backend.- ClickHouse is reachable only through the query gateway, which verifies Ed25519-signed query envelopes minted by the api. - The tracker has a hard byte budget; a change that exceeds it fails CI. - The Postgres schema this repository builds contains no billing tables, and a CI job asserts that against a real database rather than a file list. SELF-HOSTING.md is the guide: a generator script, one docker compose up -d , automatic TLS, and an explanation of every secret and every failure mode. Requirements are a Linux host with Docker, four DNS records and about 4 GB of RAM. Installing is a pull, not a build. A release publishes ten images to ghcr.io/openlabs-so/openanalytics , so a fresh host is a few minutes and needs no toolchain on it. Point four names at the host before you start. Certificates are issued on the first boot and issuance fails without them, half an hour later and nowhere near the cause: app.example.com api.example.com c.example.com rt.example.com git clone https://github.com/OpenLabs-so/openanalytics cd openanalytics git checkout "$ git tag -l 'v ' --sort=-v:refname | sed '/-/d' | head -1 " newest release, not main cd infra/selfhost ./generate-secrets.sh --domain example.com --email you@example.com --with-geoip docker compose pull && docker compose up -d then open https://app.example.com and create the first account The checkout is where the version is chosen, and it is chosen once. The generator reads the tag back out of the tree it is standing in and points .env at that release's images, printing which it picked and why; on a branch, on main , or with no git at all it writes the build defaults instead. That is not a convenience — the compose file, the env templates and the migrations ship with the images, so a release's images against another tree is a configuration nobody has tested. Images are amd64. On arm64, or to run a branch, build the ten here instead: same compose file, one flag, about ten minutes and swap on a 4 GB box. Later, ./upgrade.sh moves between releases and takes the snapshot ./rollback.sh needs, because migrations do not go down : the way back is a restore, and a restore discards what arrived after the upgrade. It tells you that before it starts, not at rollback time when you no longer have a choice. RELEASING.md /OpenLabs-so/openanalytics/blob/main/RELEASING.md is what a version number here means. To run it from source instead — for development, or to slot the services into infrastructure you already have — follow Running from source /OpenLabs-so/openanalytics/blob/main/SELF-HOSTING.md running-from-source . The order matters and one obvious order does not work: the migration runners are compiled output, so pnpm run build comes before pnpm run migrate:postgres . infra/selfhost/env/ .env.example documents every variable each service reads, and there is one file per service on purpose — the environment schema forbids some keys to some services, so a single shared .env cannot be correct. The AI assistant OPENAI API KEY and object storage are optional: unset, those surfaces disable themselves and everything else runs. Run the test suite the way CI does: pnpm run test unit + contract + tracker, no infrastructure needed pnpm run verify everything CI checks, including boundaries and the size budget No cookies, no fingerprinting, no cross-site identifiers. Visitor identity is a daily-rotating salted hash; raw IP addresses are never stored. Do Not Track and Global Privacy Control are honored at the collector, before anything is written. City-level geolocation is opt-in per site. Geolocation is resolved locally against a database on your own disk — no lookup ever leaves the host. None is bundled a 60 MB download, and stale within a month ; infra/selfhost/geoip/fetch-dbip.sh downloads one. IP Geolocation by DB-IP — https://db-ip.com — used under CC BY 4.0 .

This repository used to receive periodic exports from a private monorepo, and a merged PR was flattened by the next one; that ended in August 2026.
