The verdict: can you vibe code Trello?
Build a personal Kanban board subset with live sync, but keep paying for the enterprise ecosystem and polished Power-Ups.
Creating a personal Kanban app with lists, cards, and drag-and-drop is a satisfying project, but replicating production Trello requires solving tricky realtime synchronization, conflict resolution, and fractional indexing for item ordering. While an AI coding agent handles the CRUD boilerplate and database schema easily, managing WebSockets, optimistic UI updates, and drag-and-drop boundary states will test your debugging patience.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- The massive library of 200+ official third-party Power-Ups and integrations
- Atlassian enterprise compliance, SOC 2 Type 2 certs, and SAML SSO infrastructure
- Native mobile apps across iOS, Android, macOS, and Windows with offline sync

Build guide
01Project Scaffolding and Database Schema Setup
Initialize a Next.js project with Tailwind CSS, configure better-auth, and set up the relational schema in Turso for Workspaces, Boards, Lists, and Cards.
Scrape together a new Next.js project using App Router and TypeScript. Install Tailwind CSS and set up a robust layout for a SaaS application. Create a database schema using Drizzle ORM connected to Turso with tables for users, workspaces, workspace_members, boards, lists, and cards. Each card must have a fractional position index (string or float), title, description, due date, and labels. Configure better-auth for email/password authentication linked to the Turso database. Ensure all relational constraints and foreign keys are strictly enforced with cascading deletes.02Core Kanban Board UI and Drag-and-Drop Implementation
Build the visual board view with horizontal scrolling lists and drag-and-drop card reordering using @dnd-kit.
Build a Kanban board interface in Next.js resembling Trello. Implement a horizontal scrollable view containing collapsible lists, where each list contains draggable cards. Use @dnd-kit/core and @dnd-kit/sortable to enable smooth drag-and-drop reordering of cards both within the same list and across different lists. When a card is dropped, calculate its new fractional index position and execute a server action to update the database state optimistically without causing layout flicker.03Card Details Modal and Advanced Attributes
Implement a slide-over modal for cards supporting descriptions, checklists, due dates, and activity comments.
Create a comprehensive card detail modal that opens when clicking any card on the Kanban board. The modal must support editable markdown descriptions, interactive task checklists with item completion toggles, due date pickers, label color tags, and a threaded comment section for team activity logs. Implement optimistic UI updates for checklist items and comments, persisting changes immediately to backend API routes backed by Turso.04Realtime Collaboration with WebSockets
Add real-time synchronization so multiple browser windows reflect board movements, new lists, and card edits instantly.
Integrate real-time synchronization into the Kanban board using Socket.io or Supabase/Turso real-time channels. When any user drags a card, edits a title, creates a list, or adds a comment, broadcast the event to all other clients currently viewing that board. Handle incoming websocket payloads cleanly in React state to update the local board view instantly without requiring manual page refreshes, and handle connection dropouts gracefully.05AI Board Generation and Card Summarization
Integrate the Vercel AI SDK and Anthropic API to allow users to generate entire boards from a goal description and auto-summarize card notes.
Integrate the Vercel AI SDK using Claude Sonnet to add AI features to the board. Implement a 'Generate Board with AI' modal where typing a project goal automatically creates a complete board structure with relevant lists and prepopulated cards. Add an AI assistant button inside the card detail modal that summarizes long comment threads and fixes grammar in card descriptions. Handle streaming responses securely via server actions.06Polish, Workspace Settings, and Deployment
Add workspace switcher navigation, user management, error handling, and deploy the application to Vercel.
Add workspace administration views allowing users to switch between workspaces, invite members by email using Resend transactional emails, and manage board visibility settings. Implement robust error boundaries, toast notifications for failed network actions, loading skeletons for data fetching, and prepare environment variable configurations for deployment on Vercel and Turso.

Vibe code Trello: FAQ
- Can you vibe code Trello yourself?
- Solid side project — 68/100 vibecodeable. Build a personal Kanban board subset with live sync, but keep paying for the enterprise ecosystem and polished Power-Ups.
- How long does it take to vibe code Trello?
- 2-3 weeks part-time — roughly 35-50 hours of hands-on time with an AI coding agent.
- How do you build your own Trello?
- Scoped to personal use: Next.js with Tailwind CSS and @dnd-kit/core for drag-and-drop boards on the front, Next.js API routes with Socket.io or Turso real-time syncing behind it, Turso (SQLite at the edge) for fast board, list, and card persistence for data. 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 Trello 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: 2-3 weeks part-time. The prompts on this page are written so the AI does the heavy lifting.
