Analytics and monitoring decision
Sleek Analytics
A competent developer can build a usable, privacy-first realtime analytics replacement using open-source projects (Umami/Plausible) for core ingestion and UI, but reproducing Sleek's full polished product (AI chat, managed revenue connectors, scaling and commercial polish) is non-trivial and argues for keeping the paid service for those features.

Open-source builds that already do this
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. All Sleek Analytics alternatives, with the arithmetic →
What a replacement has to do
- Collect pageviews/events via a tiny script, ingest and deduplicate events at a collector API, store events and materialized aggregates in a database, serve a realtime dashboard (active visitors, top pages, sources) and simple retention, and optionally expose a public read-only dashboard.
What it still won’t have
- Polish and UX of Sleek's commercial dashboard (AI chat, live globe, customer-facing polish)
- Built-in AI Chat natural-language query feature
- Managed revenue-attribution connectors and onboarding
- Guaranteed event retention SLAs, scaling to millions of events without ops
- Support, hosted reliability, and security / DPA paperwork from vendor
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hosted privacy-first web analytics clone with a Node.js collector, ClickHouse or Postgres for storage, a ~1KB async tracking script, a React SPA dashboard, and a realtime visitors panel. In scope: tracking script (data-site key), /collect HTTP endpoint that validates and deduplicates events, event schema and storage, materialized aggregates for top pages/sources, WebSocket/SSE for live visitors, a React dashboard showing realtime visitors, top pages, sources, and event counts, and a Stripe webhook handler for optional revenue events and basic attribution. Out of scope: natural-language AI chat, advanced data-retention policies, enterprise SLA, and multi-region infra. Include error handling, request validation, tests for collector and core queries, Docker-based deployment, and a basic CI workflow.

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.
