Is Claude Code or Aider cheaper for daily use?

It depends on your usage. Claude Code is $20/month flat (Pro) or $200/month (Max), with predictable cost. Aider charges nothing for the tool but routes through your own API key — at moderate use ($5-$15/month in Anthropic API spend), Aider is cheaper; at heavy use (>$30/month in API), Claude Code Pro is cheaper because the subscription absorbs runaway costs. For under 20 sessions/week, Aider wins on cost; above that, Claude Code Pro wins.

Which has better agentic autonomy?

Claude Code wins on raw agent loop quality — it can plan, edit, run tests, iterate on failures, and self-correct across dozens of files without supervision. Aider runs a tighter, more deterministic edit-commit loop: it shows you a diff, asks for approval, then commits. Claude Code is more autonomous; Aider is more auditable.

Can I use Claude Code and Aider together?

Yes, and many devs do. Use Aider for surgical edits where you want git-diff-level transparency, and Claude Code for heavy multi-file refactors and long planning loops. They share the filesystem cleanly because both are CLI-first and respect your git history.

Which handles 200K+ LOC monorepos better?

Claude Code — it ships with a 1M context window on the Sonnet/Opus tier and an internal subagent system that can summarize codebases on the fly. Aider relies on a repo map (filename + signatures) plus on-demand file loading; it works on huge codebases but you have to feed it the right files. For pure "let the AI figure out where to look," Claude Code wins.

Is Aider open source enough for enterprise use?

Yes — Aider is Apache 2.0 licensed and runs entirely on your machine. The only external call is to whichever model API you configure (OpenAI, Anthropic, local Ollama, etc.). For air-gapped or compliance-sensitive environments, pair Aider with a local model and you have a fully self-hosted AI coding setup. Claude Code requires Anthropic's cloud.
