Bolt vs v0
Two of the most popular vibe coding platforms, built on completely different infrastructure. bolt.new runs on Supabase, v0.dev runs on Vercel. Here's how they compare.
v0 is 2.7x faster per request — 134ms median CRUD latency vs Bolt's 363ms. Bolt has proven burst handling — tested up to 500 concurrent users with zero errors and 203 RPS. v0's burst test was capped at 10 users by Vercel's load-test detection, so we can't compare concurrency directly.

Frequently asked questions
Is v0 faster than Bolt?
Yes, substantially. v0 delivers 134ms median CRUD latency compared to Bolt's 363ms — about 2.7x faster on individual API requests. The difference stems from the serverless runtime layer — Vercel Serverless Functions vs Supabase Edge Functions.
How does Bolt handle concurrent users?
Bolt handles concurrency well. At 500 simultaneous users, it maintained 203 requests per second with zero errors. Latency increased to 2.3s median at that level, which is expected behavior under heavy load. v0's concurrency wasn't fully tested due to Vercel's load-test safeguards.
Which has better database query performance?
v0 — its filtered list queries run at 148ms vs Bolt's 296ms, and aggregation queries at 149ms vs 317ms. Both use managed Postgres, but the different serverless runtimes and generated SQL create a significant performance gap.
Should I use Bolt or v0?
Choose Bolt if you want a browser-based IDE with WebContainers, team collaboration, and proven high-concurrency performance. Choose v0 if individual request speed matters most and you want tight integration with the Vercel deployment platform.
