The verdict: can you vibe code Pirsch?
You can build a functional personal clone of Pirsch for yourself, but you will hit friction designing an efficient event ingestion and aggregation pipeline.
Analytics tools look deceptively simple on the surface—just a JS tag and a dashboard graph. However, as soon as your sites receive traffic, raw event tables explode in size. Writing real-time queries over raw logs causes database timeouts, forcing you to implement pre-aggregated rollups or switch to a columnar store. While AI agents write CRUD dashboards and charts rapidly, designing and debugging a robust ingestion and aggregation backend falls squarely on your architecture skills.

Build guide
01Project Scaffolding & Database Schema
Initialize a Next.js project with Tailwind CSS and configure Turso with better-auth and tables for sites, pageviews, and events.
Scaffold a new Next.js project using App Router, TypeScript, and Tailwind CSS. Configure Turso (libSQL) as the database with Drizzle ORM. Define tables for users, websites (id, user_id, domain, created_at), pageviews (id, website_id, path, referrer, browser, os, country, visitor_hash, timestamp), and custom_events (id, website_id, name, visitor_hash, timestamp). Install better-auth and configure email/password authentication linked to the user table. Create an initial migration script and verify database connectivity.02Lightweight Collection Script
Build a vanilla JavaScript tracking snippet that captures page views and sends them to an ingestion endpoint.
Create a public static JavaScript file (`public/pirsch.js`) designed to be embedded on external websites. The script should read `window.location.pathname`, `document.referrer`, parse the user agent for browser and operating system details, and send an asynchronous `navigator.sendBeacon` or `fetch` POST request to `/api/v1/track`. Implement error handling and ensure the script size remains under 2KB. Create the `/api/v1/track` Next.js API route to receive payloads, extract the visitor's IP address from headers, generate an anonymized rotating SHA-256 visitor hash combining the IP and User-Agent, and insert a row into the pageviews table.03Dashboard Layout & Site Management
Build the main dashboard interface for managing websites and viewing high-level analytics metrics.
Build a dashboard layout in Next.js featuring a sidebar navigation, site switcher dropdown, and a modal to add new websites. Create a settings page where users can view their tracking snippet HTML code and domain settings. Style all components cleanly using Tailwind CSS to mimic a professional analytics SaaS interface. Protect all dashboard routes using better-auth session checks.04Analytics Overview & Aggregation Queries
Implement dashboard metric cards and charts for page views, unique visitors, browsers, and referrers.
Build the main analytics overview page for a selected website. Create backend API routes that query the pageviews table to calculate total page views, unique visitors (distinct visitor_hash), bounce rates, and time-series trends grouped by day or hour. Use Recharts to render clean line charts for page views over time and bar/list components for top referrers, paths, browsers, and operating systems. Add a date range filter selector (e.g. last 7 days, last 30 days).05Custom Events & Conversion Goals
Add support for tracking custom user interactions and conversion goals.
Extend the tracking script (`pirsch.js`) to expose a global function `window.pirsch.event(name, meta)` that sends custom events to `/api/v1/event`. Create the backend ingestion route for custom events and store them in the custom_events table. Build a 'Goals & Events' section in the dashboard that lists custom events triggered, total counts, and conversion rates over time.06Data Filtering & CSV Export
Implement interactive table filtering and CSV data export functionality.
Add interactive click-to-filter functionality on dashboard metric tables (e.g. clicking a browser name filters all charts and queries by that browser). Implement a CSV export endpoint that queries all page views and events for a given website and date range, streaming it back as a downloadable CSV file. Add an export button to the dashboard settings page.
