How to vibe codeSiter.io
No-code website builder and web design tool

The verdict: can you vibe code Siter.io?
Build a simplified single-user design canvas subset, but keep paying if you need reliable production hosting and seamless Figma imports.
Replicating Siter.io requires building a performant vector/canvas editor in the browser, handling real-time multiplayer cursor synchronization, and writing a complex Figma parser. While AI coding tools can scaffold the UI layout and basic state management quickly, getting a buttery-smooth freehand canvas to parse and export responsive code without breaking is a massive engineering hurdle for a solo developer.
Estimated effort: 3-6 months of serious part-time work

The hard parts of vibe coding Siter.io
- Achieving 60fps freehand canvas performance with panning, zooming, and resizing handles
- Writing a robust bi-directional Figma parser that translates Auto Layout and vector fills to DOM elements
- State synchronization via CRDTs or WebSockets for real-time multiplayer editing without race conditions
- Translating absolute canvas positions into clean, responsive layout trees

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js application with Tailwind CSS, configure Turso for database storage, and set up better-auth for user sessions.
Scaffold a new Next.js project using App Router and TypeScript. Install Tailwind CSS and configure a modular component structure. Set up a Turso database client using libSQL, and define database schemas for users, projects, pages, and element JSON trees. Integrate better-auth with email/password authentication and secure session cookies. Ensure all configuration files are complete and ready for local development.02Visual Canvas Editor Foundation
Build the core freehand design canvas interface with zoom, pan, element dragging, and properties inspector.
Create a React-based visual canvas component that supports infinite panning, zooming, and freehand element placement. Implement a selection model where clicking canvas items (rectangles, text blocks, images, buttons) highlights them with resizing handles. Build a sidebar properties inspector that lets users modify width, height, background color, border radius, and typography for the currently selected element. Store canvas state as a reactive JSON tree in React state, syncing dirty states back to the Turso database.03Layers, Groups, and Animation Settings
Add a layers panel for managing node hierarchies, grouping elements, and configuring animation triggers.
Build a layers tree view sidebar that mirrors the canvas element hierarchy. Allow users to reorder layers via drag-and-drop, lock elements to prevent editing, toggle visibility, and group multiple elements together into container nodes. Add an animation settings panel allowing users to attach CSS animation presets (fade-in, slide-up, scale) and trigger conditions (on-load, scroll-into-view) to any canvas element.04Real-Time Multiplayer Collaboration
Integrate Liveblocks to enable live multi-user cursor tracking and concurrent element editing.
Integrate Liveblocks into the canvas editor to support real-time multiplayer collaboration. Configure room presence so teammates see each other's live cursors with user names and colors. Bind canvas element modifications (position, styling, additions) to Liveblocks Yjs shared document structures so changes sync instantly across active browser sessions without race conditions.05Figma JSON Import Parser
Implement a parser capable of translating exported Figma node trees into native builder elements.
Build an import utility API route and client modal that accepts pasted or uploaded Figma JSON node trees (from a companion plugin export). Write a recursive parser function that maps Figma frames, rectangles, text nodes, and auto-layout flex properties directly into the application's internal canvas element JSON schema, preserving nested hierarchies and fills.06Publishing Engine and Static Export
Create a compilation pipeline that converts visual project trees into responsive HTML/CSS pages and deploys them.
Build a publishing service that compiles the project's element JSON tree into clean, responsive HTML and CSS strings. Create a deployment route that pushes the compiled static assets to Cloudflare Workers/R2 storage under a dynamic project subdomain (e.g. projectname.yourdomain.com). Ensure custom fonts, images, and embedded styles render correctly on the published output.

Vibe code Siter.io: FAQ
- Can you vibe code Siter.io yourself?
- Serious undertaking — 35/100 vibecodeable. Build a simplified single-user design canvas subset, but keep paying if you need reliable production hosting and seamless Figma imports.
- How long does it take to vibe code Siter.io?
- 3-6 months of serious part-time work — roughly 80-120 hours of hands-on time with an AI coding agent.
- How do you build your own Siter.io?
- Scoped to personal use: Next.js on the front, Next.js API Routes behind it, Turso 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 Siter.io 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: 3-6 months of serious part-time work. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Siter.io instead of paying?
- About ~$32 one-time (AI tools + domain) to start and ~$5/mo to run, versus $24/mo (Pro Plan) for Siter.io. Break-even: Never (built for learning and personal customization).
- What stack should you use to vibe code Siter.io?
