Devika — Open-Source AI Software Engineer

Devika is an open-source autonomous AI software engineer with 19,400+ GitHub stars, built as the first open-source alternative to Cognition AI's Devin. Give Devika a high-level task in natural language and she plans the approach, researches the web for context, writes code across multiple files, and iterates until the task is complete. She supports Claude 3, GPT-4, Gemini, Mistral, and local LLMs via Ollama. Devika makes complex software engineering tasks accessible to anyone through a chat-based web interface.

Works with: Claude 3, GPT-4, Gemini, Mistral, Groq, Ollama (local models). Best for developers wanting an AI pair programmer that can independently research, plan, and code. Setup time: under 10 minutes.

Devika Agent Architecture

How Devika Works

User: "Build a dashboard that shows real-time crypto prices"
    │
    ├─ 1. Planning Agent
    │     Breaks task into steps:
    │     - Research crypto APIs
    │     - Choose web framework
    │     - Design data model
    │     - Build frontend
    │     - Add real-time updates
    │
    ├─ 2. Research Agent
    │     Browses the web via Playwright:
    │     - CoinGecko API documentation
    │     - Next.js dashboard examples
    │     - WebSocket best practices
    │
    ├─ 3. Coding Agent
    │     Writes code across files:
    │     - api/prices.py
    │     - components/PriceChart.tsx
    │     - utils/websocket.ts
    │     - README.md
    │
    └─ 4. Review & Iterate
          Self-reviews code quality
          Fixes bugs if found
          Reports completion

    "Ollama":    {"models": ["any local model"]},
}

Web Research Engine

Devika uses Playwright for autonomous web browsing:

Research Flow:
1. Extract keywords from user task
2. Search the web (Google, Bing, DuckDuckGo)
3. Open relevant pages
4. Extract and summarize content
5. Build a knowledge base for coding

This means Devika can:

Read API documentation before writing integration code
Study existing implementations for inspiration
Find and apply solutions from Stack Overflow
Understand framework conventions from docs

Project Management

Each task creates a project with:

File tree structure
Step-by-step progress tracking
Code history and diffs
Research notes and sources
Agent state visualization

Chat Interface

The web UI provides:

Natural language conversation with Devika
Real-time progress of planning → research → coding phases
Code preview with syntax highlighting
Project file browser
Model selection dropdown

FAQ

Q: What is Devika? A: Devika is an open-source AI software engineer with 19,400+ GitHub stars — the first open-source Devin alternative. She autonomously plans, researches, and writes code from natural language instructions.

Q: How is Devika different from GitHub Copilot or Cursor? A: Copilot and Cursor assist with code completion in an editor. Devika is an autonomous agent that independently researches the web, plans multi-step approaches, and writes complete multi-file projects from scratch — no IDE required.

Q: Is Devika free? A: Yes, open-source under MIT license. You bring your own LLM API keys (or use free Ollama).
