Analytics and monitoring decision
Mixpanel
A small team can reproduce core analytics (event ingestion, funnels, dashboards) using open-source tooling, but you won't match Mixpanel's proprietary low-latency query engine, AI agents, experiments, and enterprise polish without significant additional engineering and infra investment.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Collect events from clients, store and index events, run funnel/retention queries, render dashboards/reports, (optional) store session replay blobs and serve replay UI
What it still won’t have
- Proprietary high-performance query engine (Arb) and its low-latency queries
- Enterprise-grade AI agents, anomaly/root-cause analysis, and Mixpanel AI features
- Built-in experiments/feature flags with statistical analysis
- Polished session replay indexing and search at scale
- Out-of-the-box governance, compliance tooling, and enterprise support SLAs (SAML/SCIM/audit logs)
What remains hard
- Infrastructure at scale
With lightning-speed queries powered by our proprietary database Arb, you can spot critical behavioral trends and patterns in seconds.
- Brand trust

First-year cost
No published price
Mixpanel does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted product-analytics service using: ClickHouse (or Postgres+Materialized Views) for event storage, Kafka (or Redis Streams) for ingestion pipeline, a Python or Node.js ingestion API, and a React single-page app for dashboards. In scope: HTTP event ingestion endpoint + client tracking snippet, storage schema for events, ingestion worker to populate aggregated tables, APIs for funnels and retention queries, a web UI to create/view simple funnels and saved reports, basic auth, and object storage integration for session replay blobs. Out of scope: distributed proprietary query engine, AI agents, experiment/feature-flag runner, enterprise SSO/SCIM. Deliver: Docker-compose deployment scripts, CI tests for ingestion and query correctness, basic monitoring/alerts, and error handling for malformed events and storage failures.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
