About

Cline CLI brings the popular Cline VS Code extension's autonomous agent capabilities to the terminal, currently in preview for macOS and Linux. It supports any OpenAI-compatible API, giving you complete model freedom—use Anthropic for complex reasoning, GPT for speed, or local models via Ollama for privacy. The terminal-native design means it works on headless servers, Docker containers, and SSH sessions where GUI tools cannot run. Cline CLI inherits the same autonomous agent loop as its VS Code counterpart: it plans actions, requests human approval, executes file edits and terminal commands, checks results, and iterates until the task is complete. Custom system prompts allow tailoring the agent's behavior for specific workflows, and compatibility with the Cline desktop ecosystem means configurations and workflows sync between terminal and editor. Cline CLI is free and open source—you pay only for LLM API usage. It is best for developers who want autonomous AI assistance in terminal-only environments, CI/CD pipelines, or remote servers. The preview status means it is less battle-tested than Aider and has fewer features, but for Cline users who want terminal access, it provides a unified experience across editor and command line.

Deals, Discounts & How to Save

Many CLI tools are open source and free—you only pay for the LLM API. Use local models via Ollama for offline, zero-cost AI coding. Free tiers like Gemini CLI (1000 req/day) cover most individual developer needs without spending a cent.
