Aider
- +Fully open source (Apache-2.0) and free; you only pay your chosen model provider
- +Git-native: every AI change is a reviewable, revertible commit
- +Model-agnostic with a repo map that scales to larger codebases
- -Terminal-only with no GUI or IDE-native experience for those who want one
- -Runs locally and edits real files, so a human must review every change
LM Studio
- +Polished cross-platform desktop GUI (macOS, Windows, Linux) with a built-in model browser and chat, easier for non-CLI users than raw runtimes
- +Runs both GGUF (via llama.cpp) and Apple MLX models, and exposes an OpenAI-compatible local server plus Python/JS SDKs
- +Free for personal and commercial use (since July 8, 2025), private and offline by default, with an MCP client built in
- -Infrastructure and chat client, not an agent: it serves models but does not plan, act, or orchestrate on its own
- -The core desktop app is not open source (unlike some local-runtime peers), though its SDKs and CLI are on GitHub
