Cline (formerly Claude Dev)

By Cline Bot | cline.bot

Models Included

• Claude 3.5 Sonnet (primary)
• GPT-4 / GPT-4o
• Gemini 1.5 Pro
• Any model via API key
• Local models via Ollama

Pricing Plans

• Free: Open source, self-hosted
• Your API costs: Pay per token to your chosen provider
• Cline Pro: $15/mo (hosted version, priority access)

How It Works

Cline is a VS Code extension that acts as an agentic coding assistant. Unlike simple autocomplete tools, Cline can:

1. Read and understand your codebase — explores files, understands structure
2. Plan and execute multi-step tasks — breaks down complex requests
3. Use tools — terminal, browser, file editor, search
4. Ask clarifying questions — doesn’t just guess what you want
5. Self-correct — reviews its own output and fixes mistakes

Pros

• Completely free (open source)
• Agentic — can plan and execute complex tasks
• Transparent — shows you every step it’s taking
• Self-correcting — reviews and fixes its own work
• Multi-model — use any model via API
• Active development — regular updates and new features
• Strong community — GitHub stars and contributors

Cons

• Requires API credits — not free to use with cloud models
• Can be slow — agentic workflows take time
• Complex setup — requires API keys and configuration
• Can get stuck — may loop on complex tasks
• No offline mode — requires API access
• Resource-intensive — can use many tokens per task

Best For

Developers who want a free, open-source agentic coding assistant and don’t mind paying for API credits.
