The verdict: can you vibe code Kittl?
Build a simple browser design scratchpad with AI image generation, but keep paying for Kittl if you need professional vector editing and templates.
Replicating Kittl is a monumental engineering feat for a solo developer primarily because of the vector graphics editor core. While an AI coding agent can quickly spin up a Next.js shell, auth, and API wrappers for fal.ai or Ideogram, building a browser-based vector manipulation engine with non-destructive text effects and path editing requires deep graphics programming (Fabric.js, Paper.js, or raw WebGL/Canvas) that standard AI assistants struggle to architect cleanly without severe performance bottlenecks. Furthermore, syncing multi-user canvas state in real time requires complex CRDT plumbing.
Estimated effort: 4-6 months of serious part-time development

Build guide
01Project Scaffolding & Database Schema
Initialize the Next.js application with Tailwind CSS, configure Turso database connectivity, and establish the user and project data models.
Initialize a new Next.js project using TypeScript and Tailwind CSS. Set up Turso for database connectivity using Drizzle ORM. Create the database schema for users, projects, and design assets (storing canvas JSON state, thumbnails, and creation metadata). Ensure proper environment variable configuration and write a health-check endpoint to verify database queries work seamlessly.02Authentication System Setup
Integrate better-auth for secure user registration, session management, and login handling.
Configure better-auth within the Next.js app to support email/password authentication and Google OAuth login. Connect the auth adapter to your Turso/Drizzle database schema. Create protected dashboard layouts and user profile management pages with proper session verification middleware.03Design Canvas Core Setup
Integrate a robust HTML5 canvas library (Fabric.js or Konva.js) into a dedicated workspace view to handle shape rendering, layer management, and basic transformations.
Build a full-screen design workspace view in Next.js using Fabric.js or Konva.js wrapped in a React component. Implement a layer management sidebar, an infinite panning/zooming canvas container, and basic shape creation tools (rectangles, circles, custom text boxes). Add state persistence to save the canvas JSON structure directly to the backend database when clicking a 'Save Project' button.04Multi-Model AI Generation Pipeline
Build backend endpoints using the Vercel AI SDK and fal.ai/Ideogram APIs to generate images and vector graphics directly into the active design workspace.
Create server-side API routes that interface with fal.ai (for Flux image generation) and Ideogram API (for text-rendered graphics and logos). Build a generative AI modal sidebar in the frontend UI allowing users to input prompts, select model parameters, and automatically import the resulting generated image as a movable layer onto the active canvas.05Real-time Collaboration Integration
Incorporate Liveblocks to sync canvas states and active user cursors across multiple sessions for real-time co-editing.
Integrate Liveblocks into the Next.js design workspace to enable multiplayer real-time collaboration. Sync canvas element positions and user presence cursors across active browser sessions using Yjs and Liveblocks storage providers, ensuring concurrent multi-user edits do not cause state corruption.06Export and Polish
Implement client-side export pipelines for PNG, JPEG, and SVG formats, and apply final styling polish across the dashboard and editor UI.
Implement export functionality on the canvas editor allowing users to download their active design workspace as high-resolution PNG, JPEG, or SVG files. Polish the dashboard interface with smooth transitions, error boundaries, loading skeletons, and responsive layouts to mimic a professional SaaS application.
