Frequently asked questions

Is v0 faster than Emergent?

Slightly. v0 delivers 134ms median CRUD latency compared to Emergent's 151ms — about 13% faster. Both platforms are in the same performance tier and significantly faster than Supabase-based alternatives.

Which has more consistent response times?

Emergent. Its p50-to-p95 spreads are the tightest we measured — delete operations run 152ms p50 to 158ms p95, a 4% gap. v0 can spike: create operations range from 136ms p50 to 999ms p95, suggesting occasional cold starts on the Vercel platform.

How do their query speeds compare?

Close. v0 runs list queries at 148ms vs Emergent's 159ms, and aggregation at 149ms vs 153ms. The differences are small enough that real-world performance would be similar for most use cases.

Should I choose Emergent or v0?

Choose v0 for the Vercel ecosystem, AI-assisted UI generation, and slightly faster median performance. Choose Emergent if predictable latency matters more than raw speed — its managed runtime delivers almost zero variance between median and tail latency.
