# How to Vibe Code Your Own Usermaven (and Stop Paying for It)

> AI marketing attribution software for B2B SaaS and agencies

- Site: https://usermaven.com
- Category: Marketing Analytics & Attribution SaaS
- Platforms: Web app
- Verdict: **Serious undertaking** (45/100 vibecodeable)
- Estimated effort: 6+ weeks of part-time engineering

## Verdict

Build a simplified analytics dashboard and event collector yourself, but keep paying for the real platform if you need production ad-platform syncing and reliable multi-touch attribution.

Usermaven combines high-throughput event collection, server-side ad-blocker bypassing, complex multi-touch attribution graph traversal, and AI data querying into a single platform. While an AI coding agent can spin up a Next.js dashboard with Postgres tables and simple charts in a few days, engineering a robust event pipeline that handles millions of hits, stitches 365-day user journeys, and securely proxies requests past ad-blockers without data loss is a serious undertaking requiring significant infrastructure design and debugging.

### What you can't replicate

- Seamless pre-built bi-directional data pipelines and API tokens for dozens of ad networks and CRMs
- Production-tested server-side proxy infrastructure resilient against aggressive ad-blocker filter lists
- The exact historical data accumulation and institutional optimization of their attribution engine

Team size: Small team.

## The hard parts

- Building a high-throughput event ingestion pipeline that handles bursty web traffic without dropping packets or lagging analytical queries
- Writing multi-touch attribution logic across a 365-day lookback window to stitch fragmented visitor sessions and cross-device paths
- Configuring server-side tracking relays and Cloudflare proxy workers to successfully circumvent ad-blockers and privacy blockers
- Designing efficient columnar data storage and fast aggregation queries for funnels, cohorts, and customer journeys over millions of events

## How to vibe code Usermaven

### Prerequisites

- Node.js (free): Required runtime environment for building and running the Next.js full-stack web application.
- GitHub (free): Source control repository and deployment trigger for hosting infrastructure.
- Cloudflare account (free): Hosting the event collection API worker and edge proxy routing.

### Recommended AI tools

- Claude Code: Best-in-class agentic terminal tool for scaffolding complex multi-file database schemas, analytics aggregation queries, and frontend chart components.
- Cursor: IDE-native assistant ideal for refining dashboard UI views, tailwind layouts, and chart integrations.

### Stack

- Frontend: Next.js with Tailwind CSS and Recharts
- Backend: Next.js API routes & Cloudflare Workers for event intake
- Database: ClickHouse / Neon Postgres for time-series analytics storage
- Auth: better-auth
- Payments: none
- Other: Vercel AI SDK, Anthropic API

### Hosting

- Vercel (Hosting the Next.js analytics dashboard frontend and app routes.): $0-20/mo
- Cloudflare (Edge workers for high-throughput tracking pixel ingestion and ad-blocker proxying.): $0-5/mo
- Neon (Serverless Postgres database for user accounts, workspace configuration, and aggregated attribution tables.): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project with Tailwind CSS, configure better-auth, and set up the Neon Postgres database schema for tenants, workspaces, users, events, sessions, and attribution touchpoints.

```
Initialize a new Next.js project with TypeScript, Tailwind CSS, and App Router. Set up better-auth with email/password authentication. Create a Neon Postgres database schema using Drizzle ORM containing tables for: users, workspaces, workspace_members, events (id, workspace_id, visitor_id, user_id, event_type, url, referrer, utm_source, utm_medium, utm_campaign, timestamp, metadata jsonb), sessions (id, visitor_id, first_touch_channel, last_touch_channel, started_at), and conversions (id, workspace_id, user_id, revenue, attributed_channel, created_at). Ensure proper foreign key constraints and indexes on timestamp and workspace_id for fast analytical queries.
```

2. **JavaScript Tracking SDK & Ingestion Worker** — Build a lightweight client-side JavaScript tracking script that auto-captures pageviews, clicks, and UTM parameters, alongside a Cloudflare Worker ingestion endpoint that securely accepts events and writes them to storage.

```
Build a lightweight JavaScript tracking SDK snippet that clients can embed on their websites. The SDK should automatically capture page views, clicks on elements with data-track attributes, and parse UTM parameters from the URL query string into localStorage. When triggered, it should batch and send these events via a beacon or fetch POST request to our ingestion endpoint. Then, build a Cloudflare Worker endpoint at /api/collect that validates the workspace API key, parses incoming JSON event payloads, handles CORS headers, and buffers/inserts the raw event data into our database storage with low latency.
```

3. **Identity Resolution & Session Stitching Engine** — Implement server-side logic that merges anonymous visitor tracking sessions with identified user accounts upon login or form submission.

```
Implement an identity resolution background service in Next.js API routes. When an event contains both an anonymous visitor_id and an authenticated user_id (e.g. after a signup or login event), update all historical visitor sessions and unassociated touchpoints to link directly to that user_id. Write database migration queries and indexes to ensure fast cross-device stitching and prevent duplicate entity creation in the contacts hub.
```

4. **Multi-Touch Attribution & Funnel Analysis Engine** — Create the core analytics processing engine to calculate multi-touch attribution models (first-touch, last-touch, linear) and multi-step conversion funnels.

```
Build the attribution and funnel calculation engine in TypeScript. Create API endpoints that compute multi-touch attribution models (First-Touch, Last-Touch, Linear) by querying touchpoint sequences across a configurable lookback window (up to 365 days) leading up to a revenue conversion event. Also build a funnel calculation route that accepts an ordered array of step event names (e.g., page_view -> product_view -> start_trial -> paid_subscription), queries drop-off counts between steps over a date range, and returns conversion percentages and drop-off rates for visualization.
```

5. **Analytics Dashboard UI & Chart Visualizations** — Develop the primary SaaS dashboard UI featuring traffic overviews, conversion funnel step charts, revenue attribution breakdown tables, and user journey maps using Recharts and Tailwind CSS.

```
Create a comprehensive dashboard UI in Next.js App Router for the analytics workspace. Include a Traffic Overview page with line charts for visitors, pageviews, and sessions using Recharts. Build a Funnel Analysis view displaying conversion steps and drop-off percentages, a Revenue by Channel attribution breakdown bar chart, and a User Journey map component listing top converting paths with user counts and average LTV. Ensure clean dark/light mode styling using Tailwind CSS and responsive table layouts.
```

6. **Maven AI Natural Language Insights Companion** — Integrate the Vercel AI SDK and Anthropic API to create 'Maven AI', a natural language assistant that queries attribution and funnel metrics and presents daily automated recommendations.

```
Implement the Maven AI companion feature using the Vercel AI SDK and Anthropic API. Create an API route /api/ai/insights that securely queries recent workspace analytics tables (traffic trends, top conversion channels, funnel drop-off spikes) and injects this structured summary into a system prompt for Claude. Build a chat interface component in the dashboard allowing users to ask natural language questions about their marketing ROI and receive synthesized analytical insights and automated growth recommendations.
```
