Key Differentiator:
CLI-native terminal pair-programmer
Aider is a popular open-source autonomous coding agent that operates primarily within the command-line interface (CLI). It serves as a terminal pair-programmer, providing write access to repositories and specializing in Git-aware editing. Aider can modify existing files or create new ones based on conversational commands. Similar to Cline, Aider adheres to the BYOK (Bring Your Own Key) model, requiring users to supply their own API keys for LLMs such as GPT-4. While Aider focuses on structured, Git-aware edits and command-line efficiency, it operates at a lower level of autonomy compared to Cline's browser interaction and MCP extensibility capabilities.
