The verdict: can you vibe code Coda?
Building a personal clone of Coda is an immense undertaking; you should keep paying for it unless you are building a simplified single-user markdown wiki with basic tables for educational purposes.
Coda is a deeply engineered hybrid of a word processor, a relational database engine, a reactive formula spreadsheet, and a multiplayer collaboration server. An AI coding agent will easily scaffold a standard Next.js CRUD app with Postgres, but it will inevitably choke and break down when tasked with writing a custom CRDT sync engine, a dependency-resolving spreadsheet formula evaluator, and a virtualized multi-view database canvas from scratch. The sheer breadth of interlocking subsystems makes this a classic trap for solo vibecoders.

The hard parts of vibe coding Coda
- Building a performant spreadsheet formula parser that calculates dependency trees and handles cross-table references without layout thrashing
- Implementing low-latency real-time multi-user editing over a compound rich-text and tabular canvas via CRDTs
- Designing a sandboxed execution environment for custom third-party integrations and automations
- Client-side virtualization and memory optimization for massive tabular datasets inside docs

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js application, configure Tailwind CSS, set up better-auth, and define the core Supabase PostgreSQL schema for users, docs, pages, and relational tables.
Create a new Next.js project using App Router, TypeScript, and Tailwind CSS. Integrate better-auth with email/password authentication backed by a Supabase PostgreSQL database. Configure Drizzle ORM or Supabase client helpers to manage database connections. Define the core database schema tables: 'users', 'workspaces', 'docs', 'pages' (supporting hierarchical tree nesting with parent_id), and 'tables' with dynamic JSONB column definitions to store custom spreadsheet records. Ensure all foreign key relationships have cascading deletes and proper indexing. Output clean, modular code with strict TypeScript types.02Hierarchical Document Sidebar and Rich-Text Canvas
Build the sidebar navigation tree for nested pages and integrate a rich-text block editor canvas.
Build a collapsible hierarchical sidebar component in Next.js that renders nested doc pages fetched from the database, allowing users to create, rename, reorder, and delete pages. In the main content area, integrate a TipTap-based rich text editor supporting headings, callout boxes, lists, and inline slash commands. Implement autosaving with a debounced API mutation to persist page content as JSON to the Supabase database. Include loading states and error handling for network interruptions.03Relational Table Engine and Multi-View Layouts
Implement spreadsheet-style relational tables with multiple view switchers (grid, board, calendar).
Implement a relational database table component within the document view. Allow users to add columns of various types (text, number, select, date, relation to other tables). Create a view switcher that toggles the data presentation between a spreadsheet grid (using a virtualized table library like TanStack Table), a Kanban board grouped by select fields, and a basic calendar view. Ensure edits made in one view instantly update the underlying database records and reflect across other active views of the same table.04Spreadsheet Formula Parser and Evaluation Engine
Develop a lightweight expression evaluator for spreadsheet formulas operating on table cells.
Write a formula parsing and evaluation engine in TypeScript that supports basic spreadsheet functions (SUM, AVERAGE, COUNT, IF, CONCAT) operating on table column data. Build a dependency graph resolver to execute dependent formulas automatically when cell values change. Expose an input interface in table cells where typing '=' triggers formula suggestions and live evaluation, displaying calculated results with clear error messaging for syntax or circular reference failures.05Real-time Multiplayer Collaboration via Liveblocks
Add multi-user presence indicators and live cursor tracking to docs and tables.
Integrate Liveblocks into the Next.js application to enable multiplayer real-time collaboration. Add active user avatars in the top header, live cursor tracking with user names inside the rich-text editor and database tables, and conflict-free replicated data synchronization for document blocks. Ensure connection state changes (connecting, connected, disconnected) are gracefully displayed in the UI without interrupting user workflow.06AI Assistant Integration
Connect the Anthropic API to provide document generation, summarization, and table column enrichment.
Implement an AI assistant feature leveraging the Anthropic API. Add an inline AI command menu in the rich-text editor to prompt for content generation, text summarization, and tone rewriting. Furthermore, add an 'AI Column' feature to relational tables that automatically evaluates row data against a custom prompt template, batch-processing records and populating results back into the table cells with streaming responses.

Follow the 6-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Coda without being an expert?
- Use an AI coding tool (Claude Code) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 6+ months of full-time work. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Coda instead of paying?
