DECISION GUIDE
When to pick each, and when to skip both.
Three plain-English paths: the case for v0 by Vercel, the case for Lovable, and the free bring-your-own-key route that avoids seat fees entirely.
When to Pick v0 by Vercel
88.5 / 100- Generates pixel-perfect, accessible React components with instant copy-paste shadcn/ui CLI integration.
- Pricing model: Freemium ($20/mo Premium)
- Production trade-off: Focused on component-level frontend generation rather than full-stack database architecture.
When to Pick Lovable
87.4 / 100- Visual click-to-edit interface combined with instantaneous Supabase backend provisioning.
- Pricing model: Freemium ($20/mo Starter)
- Production trade-off: Deeply customized business logic requires exporting the repository to an external IDE.
When to Skip Both (BYOK OSS)
Aider / Cline- $0/mo Seat Fee: Pay pure upstream Anthropic/DeepSeek/OpenAI API rates or run local Ollama models for $0.
- Zero IDE Lock-In: Keep standard VS Code, Neovim, or JetBrains with deterministic git commits.
- 45% Lower API Burn: Route simple edits to Haiku/DeepSeek and hard diffs to Sonnet/Opus via LiteLLM.
