Cline

Cline is an Apache 2.0 licensed AI coding agent maintained by Cline Bot Inc., originally released as "Claude Dev" by Saoud Rizwan. The tool runs as a sidebar inside VS Code, JetBrains, Zed, Neovim, Cursor, and Windsurf, reading codebases, editing files, executing terminal commands, and driving browsers with user approval at each step. Cline targets developers who want autonomous agent capabilities without proprietary editor lock-in or model lock-in.

Key Capabilities:

• Plan and Act modes that separate solution design from code execution

• Multi-file editing with linter and compiler error monitoring across the codebase

• Diff-based approval workflow with checkpoints for undo and rollback

• Terminal command execution with real-time output monitoring for long-running processes

• Browser automation through Puppeteer for UI verification and full-stack testing

• Native MCP support for connecting databases, issue trackers, observability, and API documentation

• 30+ LLM provider support covering Anthropic, OpenAI, Google, DeepSeek, Mistral, and local Ollama models

• IDE coverage across VS Code, JetBrains, Cursor, Windsurf, Zed, Neovim, and VSCodium

• CLI for interactive chat and headless CI/CD scripting with JSON output

• Node.js SDK for building custom agents, multi-agent teams, and scheduled automations

• Client-side execution with BYOK API keys, keeping code off Cline's servers
