The right coding tool depends on where you write code and how much of your codebase it can understand. IDE integration is the first filter — a tool that lives in your editor, sees your project files and respects your stack will help far more than a general chatbot you paste snippets into. Look for accurate completions, clear explanations of suggested changes, and strong refactoring and debugging support for your main languages. Privacy deserves real attention: check whether your code is used for training, and whether a self-hosted or enterprise option exists for sensitive projects. Price against the hours it actually saves — most developers feel the difference within the first week of real use.

Open-source computer-use CLI for AI agents — reads a desktop app's accessibility tree (not screenshots) and hands the agent JSON snapshots with stable refs, so agents can click, type and scroll.
Best for: Developers giving Claude Code, Codex or Cursor hands on desktop apps without screenshots
Pricing: Open Source
Limitation: No product logo exists in the repo — the directory shows a letter tile until the project ships one
