The verdict: can you vibe code Heptabase?
Build a web-based subset of the card editor and basic whiteboard, but keep paying for the native multi-platform sync and AI tutor.
Cloning Heptabase fully requires building a desktop-grade infinite canvas rendering engine, a local-first offline synchronization database, and a stateful AI agent tutor. While an AI agent can rapidly scaffold a Next.js web application with basic block editing and a simple SVG-based canvas, getting the performance to 60fps with thousands of interconnected cards and implementing a robust CRDT/offline sync layer is a monumental engineering challenge for a solo developer.
Estimated effort: 3-6 months of focused development
What you can't replicate
- The native performance and cross-platform desktop optimization of their custom rendering stack
- The finely tuned AI Tutor and automated syllabus curriculum generation loops
- The seamless offline-first local database sync across macOS, Windows, Linux, iOS, and Android

Build guide
01Project Scaffolding and Authentication Setup
Initialize a Next.js project with TypeScript, Tailwind CSS, and set up better-auth for local user authentication to secure your personal knowledge base.
Initialize a new Next.js project with TypeScript, Tailwind CSS, and Lucide icons. Configure better-auth with a local SQLite database adapter using Turso. Create a clean dashboard layout with a sidebar navigation for Whiteboards, Notes, Daily Journals, and AI Tutor. Ensure all configuration files are robust and typescript strict mode is enabled.02Block-Based Editor and Bi-Directional Linking
Implement a rich-text block editor using TipTap or Lexical, supporting markdown shortcuts and bi-directional node linking between cards.
Build a block-based note editor component using TipTap inside Next.js. Implement extensions for markdown shortcuts, callouts, and bi-directional linking that detects [[Note Title]] patterns and creates relational links in the database. Ensure auto-saving debounce logic persists changes to the Turso SQLite database seamlessly.03Infinite Spatial Whiteboard Canvas
Build an interactive infinite canvas supporting pan, zoom, card placement, resizing, and SVG connector lines between related nodes.
Create an infinite whiteboard canvas component supporting smooth pan and zoom using pointer events and CSS transforms or HTML5 Canvas. Implement draggable card nodes that can be placed anywhere on the grid, and allow users to draw directional connector lines between cards with snap-to-edge attachment points. Store card coordinates, dimensions, and connections efficiently in the database.04PDF Annotation and Highlight Extraction
Integrate PDF.js to render documents in-app, allowing text selection, multi-color highlighting, and one-click extraction into indexable cards.
Integrate PDF.js into a dedicated document view component. Build UI controls for text selection and multi-color highlighting with coordinate mapping. Implement a feature where selecting text and clicking 'Create Card' extracts the highlighted passage, stores the source reference metadata, and instantly adds it as a new node on a selected whiteboard.05AI Tutor and Knowledge Graph Context Integration
Connect the Anthropic API to build an AI tutor and chat assistant capable of querying user notes and structuring personalized learning syllabi.
Implement an AI tutoring chat interface backed by the Anthropic API (Claude Sonnet). Build a backend retrieval service that searches user notes and card contents via vector embeddings or full-text search to inject relevant context into AI prompts. Add structured output handling to generate multi-part course syllabi and lesson progress trackers directly within the app.

Vibe code Heptabase: FAQ
- Can you vibe code Heptabase yourself?
- Serious undertaking — 34/100 vibecodeable. Build a web-based subset of the card editor and basic whiteboard, but keep paying for the native multi-platform sync and AI tutor.
- How long does it take to vibe code Heptabase?
- 3-6 months of focused development — roughly 120-160 hours of hands-on time with an AI coding agent.
- How do you build your own Heptabase?
- Scoped to personal use: Next.js with Tailwind CSS, React Flow or custom HTML5 Canvas/SVG, and TipTap for block editing on the front, Next.js Server Actions / API Routes behind it, Turso (SQLite at the edge for local-first feel) 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 Heptabase 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 focused development. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Heptabase instead of paying?
- About ~$52 one-time to start and ~$10/mo to run, versus $17.99/mo for Heptabase. Break-even: 3 months.
