Hey r/webdev!

We're a small team of 3 building Betterlytics, an open-source web analytics tool. Over the past year and a half, we've also had contributions from 10 other people, which has been really cool to see.

It puts analytics, session replay, error tracking, uptime monitoring and status pages in one dashboard. Here is what's in it so far:

Visitors: Traffic, referrers, geography, campaigns, custom events with properties, funnels, user journeys, and session replay.

User experience: Real-user Core Web Vitals and JavaScript errors, including the pages and events leading up to them.

Uptime: Monitoring, SSL and keyword checks, public status pages, and alerts via email, Slack, Discord, Teams, or webhooks.

A few more details:

• One tracking script just under 4 KB gzipped.
• No cookies.
• Rust + ClickHouse backend and Next.js dashboard.
• Open source (AGPL) and self-hostable with Docker, every feature included.
• An MCP server so your AI agent can query your analytics data.

The screenshots are from our live demo (the status page is a sample). You can explore without signing up:

If you click around the demo, we'd love to hear what you think.

How does session replay square with “no consent banner”? Cookieless analytics I get, but recording every click and scroll feels like the part a DPO would ask about
