Libra AI: Build Web Applications Using Natural Language

An open-source platform that transforms your words into production-ready applications

What is Libra AI?

Imagine describing your next web application in plain English and watching it come to life within minutes. That’s the revolutionary promise of Libra AI – an open-source platform that turns natural language into fully functional web applications.

Built for production environments, Libra AI manages the entire application lifecycle through conversational interactions. Whether you’re building a simple landing page or a complex SaaS platform, this AI-native development environment handles everything from prototyping to enterprise deployment.

Technology Stack

Category Technologies Application
Frontend Next.js 15, React 19, Tailwind CSS 4 Responsive UI components
Backend Hono, tRPC, Zod Edge API services
AI Layer AI SDK, Claude, Gemini, DeepSeek Natural language processing
Storage PostgreSQL, Cloudflare D1, Hyperdrive Data management
Deployment Cloudflare Workers, OpenNext Global distribution

Key Services

  1. Authentication Hub (apps/auth-studio)
    Manages users, organizations, permissions, and subscriptions using PostgreSQL with Neon + Hyperdrive

  2. Build Service (apps/builder)
    Compiles code with Vite’s high-performance engine

  3. Content Delivery (apps/cdn)
    Serves static assets through Cloudflare’s global network

  4. Deployment System (apps/deploy)
    Processes deployment tasks via Cloudflare Queues

  5. Request Routing (apps/dispatcher)
    Directs traffic to appropriate Worker instances

Getting Started

Choose Your Approach

🌐 Cloud-Hosted Solution (Recommended)

  1. Visit libra.dev
  2. Register via GitHub OAuth or email
  3. Describe your application in natural language
  4. Deploy with one click

Benefits:

  • Zero configuration
  • Automatic scaling

💻 Self-Hosted Solution (Developers)

# Verify system requirements
git --version   # >= 2.30.0
node --version  # >= 20.0.0 (recommended 24)
bun --version   # >= 1.0.0

Local Setup Guide

Step 1: Clone Repository

git clone https://github.com/nextify-limited/libra.git
cd libra
bun install

Step 2: Configure Environment

cp .env.example .env
# Edit the .env file with your configuration

Step 3: Initialize Databases

# Initialize main database (PostgreSQL)
cd packages/db
bun db:generate
bun db:migrate

# Initialize auth database (D1/SQLite)
cd packages/auth
bun db:generate
bun db:migrate

Step 4: Start Services

bun dev  # Start all services
# OR start individually
cd apps/web && bun dev

Step 5: Configure Stripe

stripe listen --forward-to localhost:3000/api/auth/stripe/webhook

Local Access Points

Service URL Function
Main Application http://localhost:3000 Primary interface
Email Preview http://localhost:3001 Transaction notifications

Deployment Strategies

Self-Hosting Libra

Deploy services to Cloudflare Workers:

# Reference deployment workflows:
# .github/workflows/web.yml     - Main application
# .github/workflows/cdn.yml     - CDN service
# .github/workflows/deploy.yml  - Deployment system
# .github/workflows/dispatcher.yml - Request router

User Project Deployment

Libra uses Cloudflare Workers for Platforms to deploy user projects:

  1. Worker Isolation: Each project runs in separate Workers
  2. Deployment Architectures:
    • Queue-based (V2): Uses Cloudflare Queues for asynchronous processing
    • Workflow-based (V1): Uses Cloudflare Workflows for step orchestration
  3. Deployment Process:
    • Verify user permissions
    • Create secure sandbox environment
    • Synchronize project files
    • Execute build commands
    • Deploy via Wrangler API
    • Update routing configurations

Hosted Platform vs. Open Source Edition

Feature Hosted Platform Open Source Edition
Setup Time Minutes Requires configuration
AI Capabilities Pre-configured Requires API keys
Customization Limited Full access to source
Data Control Managed by platform Fully self-controlled
Cost Model Usage-based Infrastructure costs

Choosing the Right Version

Select Hosted Platform if you:

  • Need immediate productivity
  • Prefer managed infrastructure
  • Require enterprise support
  • Value automatic updates

Choose Open Source Edition if you:

  • Require complete data control
  • Need deep customization
  • Have technical resources
  • Operate in regulated environments
