| Lovable | v0 | |
|---|---|---|
| Score (v1) | 100/100 | 95/100 |
| Prompt → live app | under 4 min | about 15 min |
| Fix prompts | 0 | 0 |
| Free-plan cost | 2.10 credits (42% of the daily 5 free credits) | $3.81 of a one-time $5 free credit (76%) |
| Setup steps | None. Lovable Cloud set up auth and the database automatically. | Six steps: accept Vercel terms, install Neon, two SQL approvals, generate an auth secret, manual Publish. |
| Sign-up flow | Email confirmation required before first login (link arrived in under 10 s). | Better Auth email/password (Neon Postgres). |
| Data isolation (user B sees user A?) | No leak | No leak |
