If you live in the terminal and want transparent Git-backed AI pair programming, Aider is the lean choice. But if you need an autonomous agent that edits across files, runs commands, and scales to multi-agent teams (now with a Kanban board), Cline wins hands‑down. Both are free/open-source (Aider freemium for cloud LLMs), so pick by workflow: pair vs. agent.

    Pick: Cline

    Cline’s new Kanban board (2026‑06) enables parallel agents with worktrees and auto‑commit, perfect for splitting a big refactor across multiple AI agents safely.

  • Developer needing multi‑model flexibility
    Pick: Cline

    Cline integrates with 15+ providers via OpenRouter, AWS Bedrock, Azure, local Ollama – and its SDK allows custom tooling – avoiding vendor lock‑in.

  • Voice/visual input power user
    Pick: Aider

    Aider supports voice‑to‑code, image and web page context, and clipboard integration with web LLMs – unmatched for multimodal coding.

  • Beginner asking many questions
    Pick: Cline

    Cline’s Plan mode explores the codebase and asks clarifying questions before acting, guiding novices through safe changes.

Frequently Asked Questions

Aider vs Cline: which should you choose?

If you live in the terminal and want transparent Git-backed AI pair programming, Aider is the lean choice. But if you need an autonomous agent that edits across files, runs commands, and scales to multi-agent teams (now with a Kanban board), Cline wins hands‑down. Both are free/open-source (Aider freemium for cloud LLMs), so pick by workflow: pair vs. agent.

Do I need to pay for either tool?

Both are free/open-source. You only pay for cloud LLM API usage (e.g., Claude, GPT) if you use them. Local models via Ollama avoid those costs.

Can Cline run multiple agents at once?

Yes. The Kanban board (added 2026‑06) lets you run multiple agents in parallel, each with its own worktree and auto‑commit, for large‑scale changes.

Does Aider work with local LLMs?

Yes. Aider supports local models via Ollama and other local providers, and can even be used via web chat copy/paste.

Which tool integrates with VS Code?

Cline is built as a VS Code extension (and JetBrains plugin), while Aider is terminal‑only. Cline also offers a CLI and SDK.

Can I approve every change?

Yes. Cline has a human‑in‑the‑loop approval for every edit and command, with an auto‑approve toggle for full autonomy. Aider auto‑commits by default but uses Git for easy reverts.

Which tool is better for large projects?

Both handle large codebases. Aider uses a map of the entire codebase, while Cline reads project structure and dependencies. Cline’s parallel Kanban agents can speed up large refactors.

Does Aider support voice input?

Yes. Aider includes voice‑to‑code input, plus support for images and web pages as context.

Does Cline have a plugin system?

Yes. Its SDK (released 2026‑05) lets you build custom tools, multi‑agent teams, and lifecycle hooks.
