Claude Code Auto-Fix Just Launched — Here's How to Build Your Own in 10 Minutes

#javascript #tutorial #python #ai

Have you seen Claude Code Auto-Fix? It just blew up on Product Hunt with 137 upvotes. The tool watches your pull requests in the cloud, automatically resolves CI failures and review comments, and keeps your PR green until it's ready to merge.

It's genuinely cool. But here's the thing — you can build the exact same thing yourself in 10 minutes using NexaAPI, and you'll have 56+ AI models to choose from instead of just Claude.

Let me show you how.

What Claude Code Auto-Fix Does

Claude Code Auto-Fix:

Monitors your GitHub PRs 24/7 in the cloud
Detects CI failures and review comments automatically
Uses AI to generate and push fixes
Keeps your PR green until merge-ready

Great product. But it's locked to one AI provider and one pricing model.

Enter NexaAPI: Build It Yourself

NexaAPI gives you access to 56+ AI models (GPT-4o, Claude 3.5, Gemini Pro, and more) at 5x cheaper than official providers. Starting at $0.003/request.

Python Code (5 lines to get started)

# pip install nexaapi
from nexaapi import NexaAPI

client = NexaAPI(api_key='YOUR_API_KEY')

def auto_fix_code(buggy_code: str, language: str = 'python'):
    response = client.chat.completions.create(
        model='gpt-4o',  # or claude-3-5-sonnet, gemini-pro — 56+ models!
        messages=[

    return response.choices[0].message.content

# Test it

    return sum(numbers) / len(numbers)  # Bug: ZeroDivisionError if empty!
'''

print(auto_fix_code(buggy_code))

JavaScript Code

// npm install nexaapi
import NexaAPI from 'nexaapi';

const client = new NexaAPI({ apiKey: 'YOUR_API_KEY' });

async function autoFixCode(buggyCode, language = 'javascript') {
  const response = await client.chat.completions.create({
    model: 'gpt-4o',
    messages: [
      {
        role: 'system',
        content: `Expert ${language} developer. Fix all bugs and explain changes.`
      },
      {
        role: 'user',
        content: `Auto-fix:\n\n${buggyCode}`
      }
    ]
  });
  return response.choices[0].message.content;
}

// Test it
const buggy = `
function divide(a, b) {
  return a / b; // Bug: no zero check!
}
`;

autoFixCode(buggy).then(console.log);
