Benchify fixes common issues in AI-generated code instantly. No more retry loops, no more debugging hell.

​
Get your API key

  1. Sign up at app.benchify.com
  2. Navigate to Settings → Credentials
  3. Click Create API Key and save it securely
  4. Set it as BENCHIFY_API_KEY in your environment

​
Install the SDK

npm install benchify

​
Fix your first file

Here’s how to fix broken AI-generated code: 
import { Benchify } from 'benchify';

const client = new Benchify({
    apiKey: process.env.BENCHIFY_API_KEY
});


const result = await client.runFixer([
  { 
    path: 'hello.js',
    contents: 'console.log("Benchify's trivial example");' 
  }
]);

console.log('Fixed code:', result);

​
Response format

The runFixer method returns different formats based on response_format: ALL_FILES (default) - Returns all files as an array: 
[
  {
    path: "hello.js",
    contents: 'console.log("Fixed hello!");' // This file was changed
  },
  {
    path: "utils.js", 
    contents: 'export const helper = () => {};' // This file was unchanged
  }
]
CHANGED_FILES - Returns only modified files: 
[
  {
    path: "hello.js", 
    contents: 'console.log("Fixed hello!");' // Only the changed file
  }
  // utils.js is not included since it wasn't modified
]
DIFF - Returns diff string: 
"--- a/hello.js\n+++ b/hello.js\n@@ -1 +1 @@\n-console.log('broken');\n+console.log('fixed');"

​
Configuration Options

The runFixer method accepts several configuration options to customize processing: 
const result = await client.runFixer(files, {
  // What to fix
  fix_types: ['import_export', 'types', 'css'],
  
  // How to return results  
  response_format: 'CHANGED_FILES',
  
  // Enable bundling
  bundle: true,

});

​
Fix Types

Control which issues to automatically fix:
Fix TypeDescriptionExample
import_exportMissing imports, wrong pathsimport { React } from 'react' → import React from 'react'
typesTypeScript type errorsMissing type annotations, incorrect types
string_literalsString literal issuesUnescaped quotes, template literals
cssCSS and styling problemsInvalid properties, missing units
uiReact/UI component issuesMissing props, incorrect JSX
ai_fallbackGeneral AI-based fixesContext-aware fixes for complex issues

​
Response Formats

Choose how results are returned: 
// Returns all files (changed + unchanged)
const allFiles = await client.runFixer(files, {
  response_format: 'ALL_FILES'
});
// Returns: FileChange[]

​
Bundling

Enable bundling to get pre-compiled code alongside your fixed files: 
const result = await client.runFixer(files, {
  bundle: true,
  response_format: 'ALL_FILES'
});

// When bundle: true, result has this structure:
// {
//   files: FileChange[],        // Your fixed files
//   bundled_files: FileChange[] // Pre-compiled bundles
// }

console.log('Fixed files:', result.files);
console.log('Bundled files:', result.bundled_files);
How it works together: Fix types determine what gets fixed → Response format determines how results are returned → Bundling optionally adds pre-compiled versions

Full integration example

Here’s a real-world generate → fix → deploy pattern with E2B and Groq: 
import { updateSandboxFiles } from './lib/e2b';
import { generateCode } from './lib/groq-client';
import { Benchify } from 'benchify';

// Initialize the Benchify client
const client = new Benchify({
    apiKey: process.env.BENCHIFY_API_KEY || 'your-api-key-here',
    baseURL: 'http://localhost:8082' // Use local dev server
});

export async function generateAndDeploy(messages: any, existingSandboxId: any, progressTracker: any) {
    // 1. Generate code with Groq
    const files = await generateCode(messages);

    // 2. Fix broken code instantly
    const processedFiles = await client.runFixer(files, {
        bundle: true // Pre-bundle for instant execution
    });

    // 3. Deploy to E2B sandbox
    return await updateSandboxFiles({
        sandboxId: existingSandboxId,
        files: processedFiles.files, // Use the fixed files
        progressTracker: progressTracker
    });
}
