Pros and cons
v0 by Vercel
Coding · freemium
Pros

- ✓Conversational iteration lets you refine components without starting over
Cons
- ×Heavily tied to React/Next.js — limited value if you use Vue, Svelte, or Angular

Pros
- ✓Completely open-source with an active community and frequent updates
- ✓Automatic git commits give a clean audit trail and easy rollback for every AI change
- ✓Works with any LLM — swap between Claude, GPT, Gemini, or local models freely
- ✓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
