v0 is Vercel’s AI agent for building full-stack apps from prompts, designs, or existing GitHub repositories. It defaults to Next.js. Lovable combines app generation with a managed backend and hosting. New Lovable projects use TanStack Start, and Git sync exports their code to a new repository.
Choose based on the codebase you need to maintain, the backend services you want to manage, and how your team reviews changes. Apps built with either tool can be deployed to Vercel.
Copy link to headingHow to compare v0 vs Lovable for your project
v0 imports existing repositories and can work in frameworks other than its default Next.js. Lovable's separate project-import feature rebuilds exported code on its supported stack. Those are different ways to bring existing work into an AI app builder.
Both tools support collaboration and ongoing application development. Compare their repository connections and deployment workflows before deciding whether to move an app or rebuild it.

Copy link to headingStart with the application's framework
v0 defaults to the Next.js App Router. Backend logic can use Server Actions and Route Handlers, which define API endpoints alongside the user interface. v0 also supports other frameworks, although its full-stack documentation describes Next.js as the most reliable option.
Lovable uses TanStack Start for new projects. It became the default on May 13, 2026, and June 22, 2026, for Enterprise workspaces. Older projects use React and Vite until upgraded.
Using Lovable alongside an existing Next.js application introduces a second framework unless the team migrates or replaces one of the apps. Check the application's routing, server code, and dependencies before treating code export as a framework migration.
Copy link to headingDistinguish repository import from project migration
v0 can import a GitHub repository, including private repositories accessible to the Vercel GitHub App. For a monorepo, the team selects the application's root directory while retaining access to shared workspace packages.
Lovable's Git sync creates a new repository on GitHub, GitLab, or Bitbucket. It cannot attach a Lovable project to an existing repository.
The separate project-import feature accepts exported code, including a repository downloaded as a ZIP. Lovable rebuilds the app on TanStack Start. It can also migrate the database and users to Lovable Cloud when the team supplies those exports. The feature is rolling out and may not appear in every account yet.
Choose repository import when the existing codebase must remain the one the team develops. Evaluate Lovable's import as a migration, including checking the rebuilt app and transferring its data.
Copy link to headingTrace how changes reach the repository
In a GitHub-backed v0 project, a chat starts from a selected base branch. Its first code change creates a working branch, where v0 commits and pushes generated changes. Publishing creates or reuses a pull request and attempts to merge it into the base branch. Repository rules determine whether checks and human approval are required.
Lovable edits and syncs one branch at a time. Developers can work outside Lovable and push commits to that branch, which sync back into the project. To review Lovable's changes before they reach main, switch the synced branch to a feature branch and merge through the team's review process.
Copy link to headingLocate the backend services and their configuration
v0 connects to services through Vercel Marketplace, including Supabase, Neon, and Upstash. Vercel Blob provides file storage. New database integrations can provision provider accounts and project environment variables, while teams can also reuse existing database stores.
The Snowflake integration (currently in beta) connects to an existing Snowflake account. A team owner configures the account before members connect their own users through OAuth.
Lovable's Cloud backend includes a PostgreSQL database, authentication, storage, and serverless functions. Teams can also connect a Supabase project. These managed services reduce infrastructure setup. Authentication providers and external services can still require configuration.
Copy link to headingCheck what each Figma method transfers
On paid plans, v0 reads Figma file or frame links. It can inspect pages, design tokens, layout, text, and assets across a file. Use a file link for a flow with several screens or a frame link for a particular screen or component.
Lovable offers three Figma methods. The plugin transfers designs and components. The Figma server uses the Model Context Protocol, or MCP, to provide live design context through the Lovable and Figma desktop apps. Uploading a .fig file supplies tokens, styles, frame structure, and a thumbnail. It does not import interactive designs or components.
Copy link to headingHow to evaluate v0 for existing applications
v0 is Vercel's AI development platform for building web apps from natural-language prompts. The February 2026 release expanded its capability for handling existing codebases, Git, and enterprise data workflows.
Its repository import lets a team generate changes against the application's dependencies and connected Vercel project settings. This is useful when the work must fit an app that the team already deploys.
Copy link to headingUnderstand what runs in the preview
Chats that use a virtual machine run in an isolated Vercel Sandbox with a Node.js environment. The agent can search the web with sources, test flows in a browser, run terminal commands, and diagnose errors.
Connecting an existing Vercel project gives the chat its Development environment variables, integrations, and framework settings. The sandbox runs the application's development server. Production deployments use separate infrastructure and their own environment variables, so test the deployed result as well as the preview.
Copy link to headingWeigh v0's advantages against its limits
v0's advantages stack up when several contributors work on a shared application:
Existing GitHub repositories can supply the code, dependencies, and conventions for generated changes.
Separate chats can use separate working branches in the same repository.
Sandbox previews run server-side code, allowing teams to test backend changes before deployment.
Design mode applies visual edits to source code, and the Figma integration can read designs across a file.
Account for these limits before adopting v0:
v0 connects to managed backend providers through Vercel Marketplace. Configuration requirements depend on the provider and application.
Figma integration requires a paid plan.
Copy link to headingExtend an application with reviewed changes
For an imported app, v0 can add a Route Handler, connect it to an existing database, build the interface, and test the flow. Those changes use the repository's dependencies and configured Development environment variables.
Importing the same repository again starts another chat whose changes use a separate working branch. Teams can work on independent changes in parallel and merge them through their configured checks and review rules.
Copy link to headingReuse the team's design system
Teams can import a design system from a repository or package sources. Generated interfaces can then use the team's components and tokens instead of the default shadcn/ui and Tailwind CSS starter.
Review the starter app that v0 creates during import. Update the saved design system when its source changes so later work uses the intended components and setup.
Copy link to headingCompare v0's plan options
v0 offers Free, Plus, Business, and Enterprise plans. Plus and Business charge per user and include monthly generation credits. Enterprise pricing is custom.
Business opts out of model training by default. Enterprise adds single sign-on via SAML and role-based access control.
Copy link to headingHow to evaluate Lovable for apps with a managed backend
Lovable combines app generation with hosting and a managed backend. Individuals and teams can describe changes in chat, test them in the preview, and publish the app from the same product.
This gives a team a defined stack to work with. Check whether that stack and its service configuration meet the application's requirements before starting a new app or importing an existing one.
Copy link to headingChoose how the agent works on a change
Lovable's project chat has three modes:
Chat mode lets users discuss the app without changing its code.
Plan mode investigates a change and writes a plan for approval.
Build mode implements changes and can verify the result.
The preview toolbar supports element selection, inline text edits, annotations, and comments. Use it to identify the element that needs to be changed or to leave feedback for a teammate.
Copy link to headingWeigh Lovable's advantages against its limits
Lovable's managed services and shared workspace reduce the infrastructure a team needs to assemble:
Cloud provides a database, authentication, storage, and serverless functions without requiring the team to operate that infrastructure.
Connectors connect apps to services such as Slack, HubSpot, and Snowflake. Chat connectors use MCP servers to supply context from tools such as Linear and Notion.
Every plan allows unlimited workspace members.
New TanStack Start projects render pages on the server, making content available before browser JavaScript runs.
Evaluate these constraints before adopting Lovable:
Existing projects require migration through the separate import feature. Git sync cannot connect to an existing repository.
Lovable uses TanStack Start for new projects and does not offer framework selection or Next.js support.
Lovable syncs one branch at a time. Reviewing its changes before they reach
mainrequires a feature-branch workflow.Manual code editing and full-project ZIP downloads require a paid plan. Free-plan users with edit access can read code and download individual files. Git sync is available on all plans.
Copy link to headingBuild an app around managed backend services
An app that needs sign-in, database records, and file uploads can use Lovable Cloud for those services. Teams can add capabilities through connectors or configure external providers where the app needs them.
Managed infrastructure does not remove provider setup. For example, SAML authentication requires configuration with the identity provider. Built-in payment integrations support Stripe and Paddle, but accepting live payments requires provider verification.
Copy link to headingCompare plan credits with operating usage
Lovable offers Free, Pro, Business, and Enterprise plans. Paid plans are priced by credits rather than seats, and members share a workspace credit balance. Paid plans add manual code editing, full-project ZIP downloads, and custom domains.
Credits cover building and chatting, as well as Cloud, deployed AI features, and connector usage, subject to included allowances. Estimate both the development activity and the services the published app will need.
Copy link to headingHow to choose v0 or Lovable for your team
Start with the application and the repository your team intends to maintain. Then compare the effort required to adopt the tool's workflow with the services it provides.
Copy link to headingChoose v0 for work in an existing repository
Choose v0 when generated changes need to use an existing GitHub codebase and its dependencies. For a Next.js app, its default framework also avoids a framework migration. Configure repository checks and approval requirements before contributors start publishing changes.
Copy link to headingChoose Lovable for its managed application stack
Choose Lovable when its TanStack Start framework, Cloud backend, and hosting meet the app’s requirements. Shared workspaces and Git sync let developers and other contributors work on the same app. Check provider setup and expected usage costs alongside the plan features.
Copy link to headingCombine the tools when needed
A product manager might validate an idea in Lovable, then use that app as a reference while a team builds the feature in an existing repository with v0. The team can also continue developing the Lovable app and deploy it on Vercel.
Changing the framework or moving an app into another codebase requires work on dependencies, architecture, and backend services. Compare that migration with the benefit of retaining the existing app before deciding to rebuild it.
Copy link to headingHow to run v0 and Lovable apps on Vercel
v0 publishes apps to Vercel. Lovable publishes to its own hosting by default, but its code can also be deployed on Vercel. Moving hosting does not require changing the app builder or migrating the backend.
Copy link to headingPublish a v0 project through its configured workflow
In a GitHub-backed v0 project, each working branch gets a Vercel preview deployment. Review that deployment and the pull request before publishing. The Publish action attempts to merge the pull request into the selected base branch and follows the repository's branch protection rules.
A pull request alone does not require a human review. Configure the repository to require approval and passing checks. If continuous integration (CI) fails or the branch has conflicts, v0 can attempt to resolve them before publishing.
Projects without GitHub can publish directly to the connected Vercel project.
Copy link to headingDeploy a supported Lovable project
Older React and Vite projects compiled into static files that a static host could serve. TanStack Start apps also run server-side code, so they need a compatible Nitro deployment target or Node.js server.
In July 2026, Vercel added zero-configuration support for Lovable apps. Its deployment guide specifies @lovable.dev/vite-tanstack-config version ^2.6.2 or higher for framework detection.
For a supported project:
Sync the Lovable project to GitHub.
Import the repository into Vercel.
Configure the environment variables and secrets the app needs.
Add the new deployment URL to the authentication provider's allowed redirect URLs, if applicable.
Test the deployed app before moving production traffic.
Vercel detects the framework and configures the build. Application credentials and sign-in settings may still need manual configuration.
Copy link to headingKeep hosting and backend migration separate
A Lovable app can keep using Cloud after deployment elsewhere. Moving its database, authentication, or other backend services requires a separate migration. Lovable's external deployment guide describes those paths.
A prototype may also need changes before release if its configuration or data model differs from production. Test the deployed app's sign-in, server code, and data access before switching traffic.
Copy link to headingConfigure credentials and deployment access
Marketplace integrations can add credentials as environment variables on the Vercel project. Snowflake uses a separate connection process. After a team owner configures an account, each member connects their Snowflake user account via OAuth and selects an allowed role. That role determines data access.
Deployment Protection controls access to deployment URLs. Standard Protection excludes production domains; All Deployments protection includes them. Choose the protection scope for the URLs the team needs to restrict.
Start a Vercel project with an existing repository, or one synced from Lovable, or choose a template.
Copy link to headingFrequently asked questions about v0 vs Lovable
Copy link to headingDoes v0 build full-stack apps or only components?
v0 builds full-stack apps with Next.js Server Actions, Route Handlers, and connected backend services. It can also generate individual components. The v0 API and its software development kit let teams add app generation to their own products.
Copy link to headingDoes Lovable support Next.js?
Lovable uses TanStack Start and does not offer framework selection. Eligible older React and Vite projects can upgrade in place, and the published site keeps serving its previous version until the next publish. Using a different framework requires work outside Lovable.
Copy link to headingCan either tool work with an existing GitHub repository?
v0 can import public and private repositories accessible to the Vercel GitHub App. Lovable's Git sync creates a new repository and cannot connect to an existing one. Its separate project-import feature, currently rolling out, accepts a ZIP of existing code and rebuilds the app on Lovable's stack.
Copy link to headingHow do Vercel and Lovable compare?
Vercel is a platform for building, previewing, and deploying web apps. v0 is its AI app builder. Lovable combines an AI app builder with its own hosting and backend, making v0 and Lovable the closest product comparison.
