Browser controlYesBuild mode drives a real browser in a remote virtual environment, clicking buttons, filling forms, navigating pages, reading console logs and network requests and capturing screenshots. YesBeyond live web search, v0 opens the apps it builds, uses them, critiques designs, debugs flows and visits external URLs, sending you screenshots of what it sees.
Sandboxed executionNoYes"Every action runs inside an isolated sandbox" — v0 uses Vercel Sandbox, a lightweight virtual machine that runs the app in an isolated environment (https://v0.app/docs/faqs).
Multi-agent orchestrationYesNo
Headless / CI modeNoNo CLI or scripted run mode is documented; the Lovable API currently only builds from prefilled share links, so the hosted MCP server is the sole programmatic driver. Yes
Models

Bring your own modelNoNoThe picker only offers Vercel's own v0 Mini/Pro/Max tiers, and the Platform API runs v0's agent with a v0 key — there is no custom endpoint, gateway or cloud deployment to point it at.

Which one would each critic pick

CriticLovablev0Pick
El Juez——not enough reviews
El Amigo6.36.8v0 — Use v0 if you ship Next.js on Vercel and want UI and full-stack scaffolding that lands in a GitHub branch, and know that training opt-out costs $100 a user and the models are Vercel's own black boxes.
El Crítico5.56.0v0 — v0 bills per token on composite models with no published methodology, charges $50 per million output tokens at the top tier, and sells the training opt-out as a $100-a-seat feature.
El Profesor5.85.5Lovable — Lovable documents a real verification loop, build errors, console, network and browser reproduction, and attaches a cost model that cannot be predicted before the loop runs.
La Inversora7.58.3v0 — v0 is a funnel into Vercel deploys with Next.js as the distribution, and a $30 plan that includes exactly $30 of credits tells you the subscription is the margin.
La Jefa5.86.0v0 — Training opt-out at $100 a user and SAML only on a custom Enterprise contract, for a tool that helps the frontend team and nobody else; approved with conditions.
El Hacker3.83.8no preference
