## What is Devika?

Devika is an open-source AI software engineer that takes high-level instructions and breaks them into steps — planning architecture, researching solutions, writing code, and fixing bugs autonomously. Think of it as an open-source alternative to Devin.

**Answer-Ready**: Devika is an open-source AI software engineer that autonomously plans, researches, and writes code. It supports Claude, GPT-4o, and local models, with built-in browser research and terminal access. 18k+ GitHub stars.

**Best for**: Developers exploring autonomous AI coding agents. **Works with**: Claude, GPT-4o, Gemini, Ollama, local models. **Setup time**: Under 10 minutes.

## Core Features

### 1. Autonomous Planning
Devika breaks high-level tasks into actionable steps:

```
You: "Build a weather dashboard with React and OpenWeather API"
Devika:
  Step 1: Research OpenWeather API documentation
  Step 2: Set up React project with Vite
  Step 3: Create weather service module
  Step 4: Build dashboard UI components
  Step 5: Add error handling and loading states
```

### 2. Built-In Research
Uses browser automation to research documentation, Stack Overflow, and API references before writing code.

### 3. Multi-Model Support

| Provider | Models |
|----------|--------|
| Anthropic | Claude Sonnet, Opus |
| OpenAI | GPT-4o, GPT-4 Turbo |
| Google | Gemini Pro |
| Local | Ollama (Llama, Mistral) |

### 4. Web UI
Clean browser-based interface showing:
- Project timeline with each step
- Code editor with syntax highlighting
- Browser research activity
- Terminal output

### 5. Code Generation
Writes complete, runnable projects — not just snippets:
- Proper project structure
- Dependency management (package.json, requirements.txt)
- Configuration files
- Basic tests

## Architecture

```
User Instruction → Planner Agent → Researcher Agent → Coder Agent → Output
                       ↓                  ↓               ↓
                  Task breakdown    Web research     Code generation
                                   & docs reading    & file creation
```

## FAQ

**Q: How does Devika compare to Devin?**
A: Devika is open-source and free. Devin is a commercial product with more polish. Devika is great for learning and experimentation.

**Q: Can it handle real projects?**
A: Best for greenfield projects and prototypes. Complex existing codebases need more mature tools like Claude Code or Aider.

**Q: Is it actively maintained?**
A: Community-maintained with periodic updates. Check the GitHub repo for latest status.
