Why Choose AutoBE?

Powered by advanced AI agents and compiler validation

⚑

Intelligent Agents

40+ specialized agents collaborate

From requirements analysis to API implementation - the entire waterfall development process is fully automated by our intelligent agent system.

β€’ Analyze β€’ Database β€’ Interface β€’ Test β€’ Realize

βœ“

AST-Based Generation

100% compilation guaranteed

AI generates Abstract Syntax Trees first, then compilers validate and generate code - ensuring structural correctness every time.

TypeScript β€’ Prisma β€’ OpenAPI β€’ Zero Errors

πŸš€

Modern Tech Stack

Proven enterprise frameworks

Built with TypeScript, NestJS, and Prisma - the most trusted tools for enterprise-grade backend applications.

PostgreSQL β€’ SQLite β€’ Production-Ready

πŸ“š

Enterprise Ready

Complete development lifecycle

Comprehensive documentation, E2E testing, and clean architecture that juniors can understand and seniors can extend with AI assistants.

Full Documentation β€’ Testing β€’ Maintainable Code

πŸ’°

Cost Effective

Reduce development time & cost

From months to hours of development time. Significantly reduce backend development costs while maintaining enterprise-grade quality.

Time Saving β€’ Cost Reduction β€’ High ROI

🌐

Open Source & Extensible

Flexible and community-driven

Open source project with support for multiple LLMs (GPT-4.1, Qwen3), local development, and seamless integration with AI coding assistants.

Multi-LLM Support β€’ Local Setup β€’ AI Assistant Ready

Technical Innovation

Why AutoBE achieves 100% compilation success where others fail

AI-Friendly Compilers

βœ•

Traditional AI Tools

Generate code as text β†’ Often contains syntax errors

βœ“

AutoBE Approach

AI generates AST β†’ Compiler validates β†’ Perfect code generation

// AutoBE Process
1. AI β†’ Abstract Syntax Tree
2. Compiler β†’ Validates Structure
3. Generator β†’ Perfect TypeScript
βœ“ 100% Compilation Success

Automatic SDK Generation

Every backend comes with a type-safe client SDK - zero configuration, 100% type safety

The SDK powers both frontend integration and E2E test generation, creating a robust feedback loop that ensures backend stability

import api, { IPost } from "autobe-generated-sdk";

// Type-safe API calls with full autocomplete
const connection: api.IConnection = {
  host: "http://localhost:1234",
};
await api.functional.users.login(connection, {
  body: {
    email: "user@example.com",
    password: "secure-password",
  },
});

// TypeScript catches errors at compile time
const post: IPost = await api.functional.posts.create(connection, {
  body: {
    title: "Hello World",
    content: "My first post",
    // authorId: "123" <- TypeScript error if this field is missing!
  },
});

E2E Test Integration

Powers AI-generated test suites

Current Limitations

Transparent about what we're still working on

⚑

Runtime Optimization in Progress

While we guarantee 100% compilation success, runtime behavior may need testing and refinement. Our v1.0 release (Q4 2025) targets 100% runtime success.

Current: 100% Compilation βœ“
Target: 100% Runtime Success
πŸͺ™

Token Consumption

Complex projects require significant AI tokens. We're implementing RAG optimization to reduce token usage by up to 70%.

Simple Todo App:~4M tokens
E-Commerce Platform:~250M tokens

Design Interpretation

AI-generated designs may differ from your vision. Always review the generated specifications before implementation.

Tip: Provide detailed requirements for better results

Post-Generation Maintenance

AutoBE focuses on initial generation. For ongoing maintenance, combine with AI coding assistants like Claude Code.

AutoBE + Claude Code = Full Development Lifecycle

Despite these limitations, AutoBE significantly accelerates backend development
