The verdict: can you vibe code Amplitude?
You can build a lightweight usage tracker and funnel dashboard with AI tools, but replicating Amplitude's behavioral graph engine and petabyte-scale columnar database is a massive engineering undertaking.
Trying to build a true drop-in clone of Amplitude is a multi-year engineering rabbit hole due to the sheer complexity of columnar event indexing, real-time funnel calculations over millions of rows, and SDK maintenance across platforms. However, a solo developer using AI coding agents can spin up a functional personal analytics tool using a columnar database like ClickHouse or Postgres with a Next.js frontend, provided you dramatically scope down the telemetry volume and analytical queries.
Estimated effort: 4-6 weeks of dedicated coding and debugging

Build guide
01Scaffold Next.js App & Database Schema
Initialize the Next.js project with Tailwind CSS, configure better-auth for single-user dashboard access, and connect to ClickHouse or Neon Postgres to define the core events table.
Create a new Next.js 16 project with TypeScript and Tailwind CSS v4. Install better-auth for authentication and configure a connection client to ClickHouse Cloud or Neon Postgres. Write a database migration script that creates an `events` table with fields: id (UUID), event_type (String), user_id (String), session_id (String), timestamp (DateTime), and properties (JSON/Map). Ensure indexes are created on timestamp, event_type, and user_id for fast range queries.02Build Event Ingestion API Endpoint
Develop a high-throughput public ingestion HTTP endpoint that receives incoming telemetry payloads from client apps, validates event schemas, and batches inserts into the database.
Implement a high-performance POST API route at `/api/v1/track` in Next.js that accepts telemetry batches. Validate incoming payloads using Zod (expecting apiKey, eventType, userId, timestamp, and event properties). Handle CORS appropriately so web apps can send tracking data cross-origin. Batch insert valid records into the ClickHouse/Postgres events table efficiently with robust error handling and rate limiting.03Implement Funnel Analysis Engine
Write analytical SQL query builders that compute multi-step conversion funnels over chronological event sequences for specified user cohorts.
Create a backend analytical query service that calculates a multi-step conversion funnel. Given an ordered list of step event names and a date range, write a SQL aggregation query that counts unique users progressing sequentially through step A -> step B -> step C within a sliding time window. Expose this via a GET endpoint at `/api/analytics/funnel` returning conversion percentages per step.04Implement Retention Cohort Engine
Build backend logic and database queries to compute N-day user retention cohorts based on initial activation events and returning actions.
Write a retention calculation module in TypeScript using SQL window functions or aggregations. The engine should group users by their first-seen activation date (Day 0 cohort) and calculate the percentage of those users who return to trigger any tracked event on Days 1, 3, 7, 14, and 30. Expose this via `/api/analytics/retention` and format the output for cohort matrix heatmaps.05Build Dashboard UI with Recharts
Construct an interactive analytics dashboard with charts for event volume over time, conversion funnels, and retention matrices.
Build a responsive analytics dashboard UI using React, Tailwind CSS, and Recharts. Include a sidebar navigation for 'Overview', 'Funnels', and 'Retention'. Create interactive chart components that fetch data from `/api/analytics/*` endpoints with date range pickers, step reordering drag-and-drop for funnels, and a color-coded retention matrix grid.06Implement Model Context Protocol (MCP) Server
Expose an MCP server interface that allows local AI coding assistants like Claude Code or Cursor to query product analytics data conversationally.
Build an MCP (Model Context Protocol) server module in TypeScript that registers custom tools for querying your analytics backend. Implement tools such as `get_event_counts`, `query_funnel`, and `get_retention_summary`. Secure the MCP transport layer so that local AI coding agents running in Claude Code or Cursor can securely fetch product telemetry data when prompted.
