What is Dev-Crew?

Dev-Crew is a free, open-source CLI that gives you an entire AI development team from your terminal. Instead of one generic AI assistant, you get 24 specialized agents — each an expert in their domain.

npm install -g dev-crew
dev-crew

That's it. Dev-Crew auto-detects your project stack and picks the best available AI provider. No API keys needed — simulation mode works out of the box.

Why Dev-Crew Over Other AI Tools?

🚀 Quick Start

Install

# Install globally (recommended)
npm install -g dev-crew

# Or use npx (no install)
npx dev-crew

# Or install from source
git clone https://github.com/vasoyaprince14/dev-crew.git
cd dev-crew && npm install && npm run build && npm link

Requirements

• Node.js 18 or higher
• AI provider (optional) — any one of: Claude Code, Aider, GitHub Copilot, OpenAI CLI, or Ollama
• Works without any AI installed using simulation mode

First Run

# Start interactive mode (default)
dev-crew

# Or initialize in your project
dev-crew init

# Check everything works
dev-crew doctor

Your First Commands

# Review code
dev-crew review src/

# Fix a bug
dev-crew fix src/api/handler.ts --issue "null reference on line 42"

Quality & Performance

💬 Interactive Mode

The fastest way to use Dev-Crew. Just type naturally:

dev-crew         # starts interactive mode
dev-crew i       # shorthand

❯ review @src/controllers/auth.ts
  ████████░░ 8/10
  ● Missing rate limiting on login endpoint
    → Add express-rate-limit middleware
  ✓ Good JWT token validation
  ✓ Password hashing with bcrypt
  review · 2,341 tokens · 3.2s

❯ fix the authentication bug in @src/auth.ts
❯ write tests for the user service
❯ is there any security issue in the API?
❯ explain how the middleware chain works
❯ how much would it cost to deploy on AWS?

Slash Commands

Tips

• Use @path/to/file to include files in your query
• Use \ at end of line for multi-line input
• Tab completion works for file paths, agents, and slash commands
• Ctrl+C cancels the current operation
• Ctrl+C twice exits Dev-Crew

📖 Complete Guide

Code Review

# Basic review
dev-crew review src/

Teaching Agents Your Preferences

# In CLI
dev-crew feedback review "Always flag console.log in production code"
dev-crew feedback security "We use Helmet.js, don't flag HTTP headers"
dev-crew feedback test "We prefer describe/it blocks over test() calls"

# In interactive mode
❯ /feedback review never suggest class components, always hooks
❯ /feedback fix preserve existing comments when fixing code

Token Management

# Estimate tokens before running
dev-crew tokens estimate src/

# View usage history
dev-crew tokens usage

CI/CD Integration

# .github/workflows/review.yml
name: Code Review
on: [pull_request]
jobs:
  review:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm install -g dev-crew
      - run: dev-crew review src/ --ci
        # Exit code 0 = pass, 2 = critical issues found

🔌 Multi-Provider Support

Dev-Crew auto-detects installed AI tools and picks the best one:

# Check available providers
dev-crew doctor

# Switch provider in interactive mode
❯ /provider ollama
✓ Ollama

# Force simulation mode (no AI needed)
❯ /provider simulation

No providers installed? Dev-Crew runs in simulation mode — you can explore every command and see the output format without any AI backend.

⚙️ Configuration

Dev-Crew vs Other Tools

Troubleshooting

"No AI provider found"

Dev-Crew needs at least one AI tool installed. Install any of:

# Claude Code (recommended)
npm install -g @anthropic-ai/claude-code

# Or Ollama (free, runs locally)
# See: https://ollama.ai

# Or use simulation mode (no install needed)
dev-crew    # auto-falls back to simulation

"Timeout" errors

For large codebases, target specific files:

# Instead of reviewing entire src/
dev-crew review @src/controllers/auth.ts

# In interactive mode
❯ review @src/services/user.ts

Command not found after install

# Check install location
npm list -g dev-crew

# If using nvm, ensure correct node version
nvm use 20
npm install -g dev-crew
