Our verdict
Aider is a terminal pair programmer that edits your local Git repository and commits each change for you, so it suits people comfortable working in a command line who want a tidy Git history. Cline is an autonomous agent inside VS Code that plans work, edits files and runs commands, asking your approval for each action, so it suits people who live in their editor and want to watch each step. Both are open source and let you bring your own model, so the choice mostly comes down to terminal versus editor and how much you want to approve as it goes.
Pick Aider if you are comfortable in the terminal, work in a Git repository, and want edits committed automatically.
Pick Cline if you work in VS Code or JetBrains and want an agent that shows and asks approval for each step it takes.

| Interface | Terminal-only command line tool; not everyone enjoys this. | Runs inside VS Code or JetBrains as an editor extension-style agent. |
| Git handling | Makes automatic Git commits for its edits. | No Git commit behavior is listed; focuses on approval of each action. |
| Control style | Lean pair programmer that edits code in your local repo. | Plans and acts autonomously, with plan and act modes and approval per action. |
| Model choice | Works with many models, using your own key. | Works with any model provider, using your own key; supports MCP tools. |
| Price | Open source; no listed fees for the tool itself. | Open source; token costs on your own API key can climb fast. |
