Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Aider

Requires comfort working in a terminal rather than a graphical IDE
Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Zed

Newer product with smaller ecosystem than established editors
Limited extensions and plugin marketplace compared to VSCode or Sublime Text
