The verdict: can you vibe code Rows?
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.
Estimated effort: 3-4 weeks part-time
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

The hard parts of vibe coding Rows
- 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

Build guide
01Project 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.02Spreadsheet 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.03AI 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.04API 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.05Real-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.

Vibe code Rows: FAQ
- Can you vibe code Rows yourself?
- Solid side project — 62/100 vibecodeable. 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.
- How long does it take to vibe code Rows?
- 3-4 weeks part-time — roughly 40-60 hours of hands-on time with an AI coding agent.
- How do you build your own Rows?
- Scoped to personal use: Next.js with Tailwind CSS, shadcn/ui, and a virtualized grid component on the front, Next.js API routes with Vercel AI SDK and Upstash QStash for background jobs behind it, Turso (SQLite at the edge) for fast tabular and relational data storage for data. Follow the 5-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Rows without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 3-4 weeks part-time. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Rows instead of paying?
- About ~$12 one-time to start and ~$10/mo to run, versus $8/mo - $79/mo for Rows. Break-even: N/A (Built for personal use).
- What stack should you use to vibe code Rows?
