How to vibe codeBubble
Build web & mobile apps with the only no-code AI app builder

The verdict: can you vibe code Bubble?
Building a functional personal clone of Bubble is impossible due to the monumental scope of engineering a visual IDE canvas, a proprietary visual AST compiler, and an isolated multi-tenant metering runtime.
Bubble is essentially a full-blown visual operating system and cloud IDE. To replicate it, you would need to build a web-based drag-and-drop canvas with component trees, a visual programming language interpreter that compiles into performant Node.js routines, a relational schema builder, a secure multi-tenant execution sandbox, and a compute-metering engine. While AI coding tools can scaffold standard web apps, building an entire visual IDE and runtime compiler from scratch is far beyond a solo side project.
Estimated effort: 6+ months of full-time work
What you can't replicate
- The 14-year maturation of its proprietary visual compiler and execution runtime
- The massive library of community-built plugins and integrations
- Enterprise-grade infrastructure isolation and high-availability AWS orchestration

The hard parts of vibe coding Bubble
- Translating a complex visual Abstract Syntax Tree into performant runtime execution without a proprietary compiler
- Building a safe multi-tenant sandbox and metering engine to track CPU and database compute per user app
- Designing a recursive WYSIWYG canvas with absolute/responsive layouts and live preview rendering
- Executing dynamic relational searches and constraints over database records inside an abstract schema builder

Build guide
01Project Scaffolding and Database Schema
Initialize the Next.js repository with Tailwind CSS, configure Neon PostgreSQL via Drizzle ORM, and set up better-auth for user authentication.
Initialize a Next.js full-stack project with TypeScript, Tailwind CSS, and Drizzle ORM connected to Neon PostgreSQL. Set up better-auth with email/password authentication. Create database tables for users, applications (storing visual layout JSON and workflow JSON trees), database_types, and database_fields to support dynamic user-defined data structures.02Visual Canvas and Component Tree Editor
Build the drag-and-drop WYSIWYG editor canvas where users can place UI elements, configure properties, and structure visual layout hierarchies.
Create a drag-and-drop visual canvas component using dnd-kit within the Next.js app dashboard. Implement a left sidebar with UI element primitives (Text, Button, Input, Group, RepeatingGroup) and a right property inspector panel. Store the canvas layout as a recursive JSON tree structure in local state and persist it to the application table.03Visual Database Schema Manager
Construct an interface allowing users to define custom data types and fields dynamically, mapping them to underlying database operations.
Build a visual database schema manager page where users can create custom Data Types (e.g., 'User', 'Product') and add fields with types (Text, Number, Date, Yes/No, Relationship to another type). Implement backend API handlers that dynamically read these definitions to generate runtime queries.04Visual Workflow Logic Builder
Develop a step-by-step conditional workflow tree editor to handle triggers (e.g., 'Button Clicked') and actions (e.g., 'Create a new thing', 'Navigate to page').
Implement a visual workflow builder interface where users select an event trigger (e.g., element click) and chain sequential actions with conditional expressions. Build an expression evaluator parser in TypeScript that can parse dynamic data expressions like 'Current User's email' or 'Result of step 1's value' at runtime.05Runtime App Preview and Execution Engine
Build a sandboxed preview runtime that parses the stored application JSON schema and workflow trees to render a live, functional web application.
Create an application runner view at `/app/[appId]/run` that fetches the target application's layout JSON and workflow definitions. Dynamically render the React components based on the layout tree and attach event handlers that execute the stored workflow steps and interact with the dynamic database models.06Resource Metering and Workload Unit Tracking
Implement a logging middleware that tracks server CPU time, database query counts, and payload sizes to simulate Bubble's Workload Unit (WU) metering system.
Add a backend telemetry middleware that measures database read/write query execution time and API payload sizes for each user application request. Calculate and aggregate simulated 'Workload Units' into a usage table, displaying a real-time analytics chart on the app dashboard.

Vibe code Bubble: FAQ
- Can you vibe code Bubble yourself?
- Impossible — 5/100 vibecodeable. Building a functional personal clone of Bubble is impossible due to the monumental scope of engineering a visual IDE canvas, a proprietary visual AST compiler, and an isolated multi-tenant metering runtime.
- How long does it take to vibe code Bubble?
- 6+ months of full-time work — roughly 250+ hours of hands-on time with an AI coding agent.
- How do you build your own Bubble?
- Scoped to personal use: Next.js with Tailwind CSS and React DnD / dnd-kit for the canvas interface on the front, Node.js API routes with a custom expression evaluator and AST interpreter behind it, PostgreSQL via Neon 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 Bubble 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: 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 Bubble instead of paying?
- About $40 one-time to start and $0-20/mo to run, versus $29/mo to $549/mo+ for Bubble. Break-even: N/A (Impossible to fully replicate core engineering scope).
- What stack should you use to vibe code Bubble?
- Next.js with Tailwind CSS and React DnD / dnd-kit for the canvas interface; Node.js API routes with a custom expression evaluator and AST interpreter; PostgreSQL via Neon; plus Zod for schema validation, Monaco Editor for code expressions, PostHog for telemetry.
