Coding · free

- ✓No IDE lock-in: use it alongside Vim, Emacs, VS Code, or anything else
Cons
- ×Terminal-only interface has a steep learning curve for non-CLI users
- ×Requires your own API keys — no turnkey experience like Cursor or Copilot
- ×No inline code completion or real-time suggestions; it's conversation-driven only
- ×Large codebases can burn through API tokens quickly with repo-map context
