Bolt vs v0 (2026 real test)
Bolt 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. Bolt was faster (about 6 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.
