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

> Your new AI Data Analyst

- Site: https://rows.com
- Category: SaaS
- Verdict: **Solid side project** (62/100 vibecodeable)
- Estimated effort: 3-4 weeks part-time

## Verdict

You can build a personal clone of Rows with a core spreadsheet grid, AI copilot, and basic API data tables, but maintaining dozens of live OAuth integrations and real-time collaboration requires significant engineering effort.

Rows is a massive engineering undertaking combining an advanced spreadsheet UI, formula parser, background job workers, and LLM orchestration. While you can bypass building 50+ individual integrations by focusing on a few custom API endpoints and an AI text-to-formula translator, managing the grid performance and WebSocket synchronization will consume multiple weekends of rigorous debugging.

### What you can't replicate

- The exact library of 50+ out-of-the-box native enterprise SaaS integrations
- The community network effects, public template gallery, and 2.2M user base
- The decade of iterative polish on formula error handling and edge cases

## What it does

An all-in-one spreadsheet platform blending standard spreadsheet functions with built-in native API integrations, collaborative workspaces, and an AI Data Analyst copilot.

### Core features

- Virtualized elastic spreadsheet grid with cell selection and formula bar
- Formula evaluation engine with dependency graph and standard functions
- AI Data Analyst copilot for natural language queries and data transformations
- Built-in API data table importers and cron background refresh schedules
- Real-time multiplayer collaboration via WebSockets
- Embeddable charts, tables, and interactive forms

Team size: ~50.

## The hard parts

- Building a buttery-smooth virtualized grid UI that supports cell navigation, formula bars, and inline editing without lag
- Writing a secure formula execution parser and dependency graph that handles circular references and range expansions
- Orchestrating scheduled background sync jobs and OAuth integrations across third-party APIs without crashing rate limits
- Implementing conflict-free real-time co-editing and multiplayer presence via WebSockets

## How to vibe code Rows

### Prerequisites

- Node.js (free): Required for running the Next.js runtime and full-stack TypeScript environment.
- GitHub (free): Version control and seamless CI/CD deployments.
- Anthropic API Key (pay-as-you-go): Powers the AI Data Analyst copilot for natural language queries and formula generation.

### Recommended AI tools

- Claude Code: Handles complex multi-file architectural scaffolding, database schema setup, and iterative debugging in the terminal.
- Cursor: Ideal for fine-tuning frontend spreadsheet components, virtualized grids, and UI layout interactions.

### Stack

- Frontend: Next.js with Tailwind CSS, shadcn/ui, and a virtualized grid component
- Backend: Next.js API routes with Vercel AI SDK and Upstash QStash for background jobs
- Database: Turso (SQLite at the edge) for fast tabular and relational data storage
- Auth: better-auth for secure, self-hosted session management
- Payments: None (personal use)
- Other: Liveblocks for real-time multiplayer presence and spreadsheet co-editing, Resend for transactional auth emails

### Hosting

- Vercel (Hosting the full-stack Next.js web application and serverless functions): $0-20/mo
- Turso (Serverless edge database for spreadsheets, rows, and cells): $0/mo
- Upstash (Serverless Redis for background data table refresh schedules and rate limiting): $0/mo

### Build guide

1. **Project Scaffolding & Database Schema** — Initialize the Next.js project, configure Tailwind CSS, set up Turso with Drizzle ORM, and implement better-auth.

```
Scrape together a new Next.js project with TypeScript, Tailwind CSS, and shadcn/ui components. Configure Turso as the database using Drizzle ORM with tables for users, workspaces, spreadsheets, tables, rows, and cells. Implement better-auth for email/password authentication with protected dashboard routes. Ensure the schema supports flexible JSON-based cell metadata and formula definitions.
```

2. **Spreadsheet Grid & Formula Engine** — Build the virtualized elastic spreadsheet grid with cell selection, keyboard navigation, and basic formula execution.

```
Build a high-performance virtualized spreadsheet grid component in React. Support cell selection, keyboard arrow navigation, inline editing, and a formula bar at the top. Implement a lightweight formula evaluation parser supporting basic functions like SUM, AVERAGE, COUNT, and basic arithmetic references between cells (e.g., =A1+B2). Store cell values and formulas efficiently in Turso.
```

3. **AI Data Analyst Copilot** — Integrate the Vercel AI SDK and Anthropic API to allow natural language text-to-formula translation and data summaries.

```
Add an AI Data Analyst sidebar panel using the Vercel AI SDK and Anthropic API. Allow users to type plain-language queries or commands (e.g., 'Summarize the total revenue in column B' or 'Write a formula to calculate profit margin'). The AI should return valid spreadsheet formulas or text answers that can be inserted directly into selected cells via tool calling.
```

4. **API Data Tables & Scheduled Background Refreshes** — Implement custom API data table imports and set up Upstash QStash to automate periodic data refreshes.

```
Create a Data Table feature that allows users to import JSON data from external public REST APIs or custom endpoints into spreadsheet ranges. Integrate Upstash QStash to handle background job scheduling, enabling automated daily or hourly data table refreshes without blocking the main server thread.
```

5. **Real-time Collaboration & Embedding** — Integrate Liveblocks for multiplayer cursors and real-time co-editing, plus embed views.

```
Integrate Liveblocks into the spreadsheet editor to support real-time multiplayer cursor presence, active user lists, and concurrent cell editing across multiple users. Add a share/embed toggle mode that allows publishing spreadsheets as read-only viewable dashboards or embeddable iframes.
```

### Cost vs paying

**Starting costs (one-time):**

- Custom domain (optional): $12/yr
- Total: ~$12 one-time

**Ongoing costs (monthly):**

- Anthropic API usage: ~$5-15/mo
- Vercel / Turso / Upstash: $0/mo (Hobby Tiers)
- Total: ~$10/mo

- Paying for the SaaS instead: $8/mo - $79/mo
- Build time: 40-60 hours
- AI tool credits: $20/mo (Claude Pro)
- Break-even: N/A (Built for personal use)
