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.

Traditional Sandbox Deploy

$ deploying generated code...

Starting container...

Running npm install...

⚠ 247 packages to install...

✗ ERROR: Cannot resolve dependency '@/hooks/useAuth'

Deploy failed after 47s

Benchify Deploy

✓ Auto-detected React + TypeScript

✓ Fixed missing imports

✓ Deployed: https://abc123.benchify.app

Same code. One fails in 47s, the other ships in 2.1s.

The Problem

Sandboxes Can't Keep Up with AI

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

Too Slow

Fresh containers spin up for every run. Even with templates, AI adds unexpected packages that trigger new installs—adding latency each time.

Container Boot2s

Install Dependencies32s

Build Project8s

Too Complex

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

Dockerfile

FROM node:18-alpine

RUN apk add --no-cache python3 make g++

WORKDIR /app

COPY package*.json ./

RUN npm ci --only=production

COPY . .

ENV NODE_ENV=production

RUN npm run build

EXPOSE 3000

CMD ["node", "dist/index.js"]

Too Brittle

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

Build Output

✗ Module not found: '@/components/ui'

✗ Cannot resolve 'framer-motion'

✗ Type error: Property does not exist

⚠ 12 more errors not shown

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,and fewer errors.

Deploy

await benchify.create({

files: [

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

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

]

});

Auto-detect • Fix imports • Cache dependencies • Build

Response

framework: "react",

fixes: ["imports", "deps"]

Key Features

Built for Speed, Not Configuration

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

Templateless

No Dockerfiles to maintain

Skip the Dockerfile hell. No base images to configure, no templates to keep in sync with your prompts. Just send code—we handle the rest.

No Docker templates to build and maintain

No prompt engineering to match your template

Works with any framework, any structure

app.tsx

import React from 'react'

→ React

vite.config

export default defineConfig()

→ Vite

utils.ts

export const utils: string

→ TypeScript

Sandbox Ready

Runtime

Node 20 + Vite

Port

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.

Intelligent dependency resolution

Version conflict auto-resolution

npm install (247 packages)45s

Benchify cache (247 packages)0.1s

Cache Hit

Wait Time

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

AI Generated (3 issues)

✗ Missing: import Button from '@/components'

✗ Package 'framer-motion' not in dependencies

✗ Type error: Property 'onClick' does not exist

Auto-Fixed (0.03s)

✓ Added: import { Button } from './components/Button'

✓ Added: 'framer-motion': '^11.0.0'

✓ Fixed: Added missing type annotation

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)
