Sandboxes that Just Work

Push generated code → get a live URL in seconds. No template, no dependency installs, no build errors. Just code that runs.

The Problem

Current Sandboxes Can't Keep Up with AI

Most sandboxes were built for predictable code. AI generates chaos.

Terminal

$ npm install

Starting container...

Installing 247 packages...

Still loading...

2min 47s elapsed...

Too Slow

Cold container boots take 30-60 seconds. Dependency installs add another 2-3 minutes. Your users give up waiting.

Terminal

$ docker build -t sandbox .

Too Complex

Dockerfiles, package.json templates, build configs, environment variables. Hours of setup before any code runs.

Terminal

$ npm run build

Building project...

✗ ERROR: Module not found

Cannot resolve '@/shadcn-ui'

⚠ Missing dependencies

✗ Build failed

$ |

Too Brittle

AI generates unexpected imports, different frameworks, novel dependencies. One missing module breaks everything.

You need sandboxes that adapt to whatever AI generates—not the other way around.

Solution

From Code to Live URL in Seconds

Just two steps. No templates, no waiting, fewer errors.

main.js

// Your LLM generates files

const files = [

{ path: 'App.tsx', content: '...' },

{ path: 'package.json', content: '...' }

]

// One API call

const sandbox = await benchify.create(files)

Traditional Deploy

Key Features

Built for Speed, Not Configuration

Three core innovations that make AI-generated code deploy instantly.

Zero Configuration

Smart auto-detection

No package.json setup, no build configs, no environment variables. We analyze your code and automatically configure everything needed to run it.

Auto-detect frameworks (React, Vue, Svelte, etc.)

Infer build commands and scripts

Generate optimal runtime configuration

Auto Configuration

$ inspecting project...

✓ Framework: React + TypeScript

✓ Build tool: Vite (inferred)

✓ Entry point: src/App.tsx

✓ Port: 3000 (auto-assigned)

Configuration complete: 0 files needed

Global Dependency Cache

Skip npm install entirely

Our distributed cache knows every package, version, and dependency tree. Most dependencies are already available, eliminating install time completely.

95%+ cache hit rate for popular packages

Intelligent dependency resolution

Version conflict auto-resolution

Dependency Resolution

$ analyzing dependencies...

✓ react@18.2.0 (cached)

✓ @types/react@18.0.28 (cached)

✓ typescript@5.0.4 (cached)

✓ 247 dependencies resolved (cached)

Install time: 0s (would be ~45s)

Static Code Fixing

Issues fixed before execution

Before your code even runs, we analyze and fix common AI generation errors. Missing imports, typos, version mismatches—all resolved in milliseconds.

Auto-import missing dependencies

Fix common syntax errors and typos

Resolve version conflicts automatically

Static Analysis

$ analyzing generated code...

✓ Fixed: import useEffect from 'react'

✓ Fixed: 'setcount' → 'setCount' (typo)

✓ Added: @types/react@18.0.28

✓ 7 issues fixed automatically

Analysis time: 0.03s

Performance Benchmarks

Time to Working Code Matters

Other providers optimize for "cold boot time." We optimize for when your users actually get working code. Measured from API call to interactive application. Variance shows reliability.

Benchify

Optimizes for complete user experience, not vanity metrics

Time to working code:

16× faster, 60× more reliable

While others optimize for cold boot time, we measure what matters: when users can actually interact with your code.

Integration

One Call. Zero Drama.

Any generated code becomes a working sandbox instantly. No template errors, no build failures, no syncing headaches.

One Line. Zero Retries.

Replace complex template management with a single API call that handles any generated code pattern.

Faster Time To Execution

Global cache ensures fast execution

Fewer Errors

Completely eliminate template and build errors

Easier Development

No need to keep prompt and template in sync

No infrastructure changes required. Your existing architecture stays exactly the same.

Complete Integration Example

import { Benchify } from 'benchify'

import OpenAI from 'openai'

⠀

// Initialize

const benchify = new Benchify(apiKey)

const openai = new OpenAI(apiKey)

⠀

// Generate

const code = await openai.generate(prompt)

⠀

// Benchify Integration

const sandbox = await benchify.sandbox.create(code)
