Base44 vs v0 (2026 real test)

Base44 scored 100/100 and v0 95/100 on our v1 test (same prompt, free plans, 16 Oct 2026). Both built a working multi-user to-do app with login and a database, with zero fix prompts, and neither leaked one user's data to another. Base44 was faster (about 3.5 min vs about 15 min).

Honest limits: one run per tool (depth Tier B), one fairly easy task, free plans only. v1 couldn't separate the top tools, so official tiers wait for the harder v2 test. These tools change weekly; results describe them on 16 Oct 2026. Payment never buys rank.

Side by side

	Base44	v0
Score (v1)	100/100	95/100
Prompt → live app	about 3.5 min	about 15 min
Fix prompts	0	0
Free-plan cost	1 of 25 monthly free message credits (4%)	$3.81 of a one-time $5 free credit (76%)
Setup steps	None. Built-in database + auth. Free plan requires the app to be public.	Six steps: accept Vercel terms, install Neon, two SQL approvals, generate an auth secret, manual Publish.
Sign-up flow	Email code. If a new user closes the code page, the login screen offers no way to enter or resend the code.	Better Auth email/password (Neon Postgres).
Data isolation (user B sees user A?)	No leak	No leak

What broke in Base44 (Observed)
