v0 Adds in-chat custom domain purchase to Its Project Sidebar.

v0 is bringing one of the last steps in launching a website directly into its AI building interface. The company now lets users purchase and add custom domains from the in-chat sidebar, reducing the need to leave a project just as it is ready to go live.

The company announced the feature on LinkedIn on December 4. Its brief announcement did not identify a separate dashboard or configuration wizard, instead saying domain purchasing and setup are available directly from the chat sidebar.

That placement matters. v0, built by Vercel, is designed around a conversational workflow in which users describe an application, review generated code and previews, and publish the result. Custom domains have traditionally introduced a different set of tasks, such as visiting a domain provider, buying an address, and configuring it for the deployed project. Bringing the purchase into the workspace makes publishing feel more like part of the same build session.

The update appears aimed at removing context switching rather than adding a new design or coding capability. A builder can work on a project in chat, open the sidebar, and handle the custom domain without moving to a separate purchasing site.

For small businesses and solo builders, that could make several common launches easier:

• Replacing a default project URL with a branded address
• Securing a domain while a product or campaign is being built
• Keeping the build, deployment and domain steps within one workspace
• Avoiding a separate domain-shopping session at the end of a project

It is a relatively narrow feature, but it addresses a consequential part of no-code publishing. Generating an application is only part of launching it. A recognizable web address is often necessary before a site can be shared with customers, used in advertising, or connected to a company’s public identity.

v0’s public product page already positions the service around a “Prompt. Build. Publish.” sequence, stating that generated applications can be published as live websites in seconds. In-chat domain purchasing extends that proposition beyond generating and deploying the application itself. It brings an element of web infrastructure into the same interface used to create the product.

The release also follows v0’s broader work to cover more of the application lifecycle. The company has added tools for programmatic generation through the v0 API, while a newer usage and activity dashboard gives teams more visibility into AI spending. Domain purchasing focuses on another operational edge: turning a generated project into a branded destination.

v0’s announcement is concise, and several practical details are not yet documented in the supplied materials. The company did not disclose domain pricing, supported top-level domains, renewal terms, registration providers, or whether every v0 plan can use the purchasing flow. It also did not explain whether the sidebar can connect domains that users already own with third-party registrars.

Builders should therefore review the terms and pricing presented during checkout before making a purchase. Domain registration creates an ongoing obligation, not just a one-time publishing step, so ownership records, renewal costs, transfer policies and expiration handling can be as important as the initial price.

The confirmed change is straightforward: users can now purchase and add custom domains from the in-chat sidebar. For v0’s target audience, the value is less about a novel domain feature and more about continuity. The project can move from an idea to a generated application and then to a branded URL without breaking the conversational workflow.

What is v0 in-chat custom domain purchase?

It is a v0 feature that lets users purchase and add a custom domain to a project from the in-chat sidebar. It is intended to reduce the need to leave the project interface during publishing.

How much does purchasing a custom domain through v0 cost?

v0 did not provide domain prices, renewal fees or plan requirements in its announcement. Users should check the pricing and registration terms shown inside the purchasing flow.

Can users connect a domain they already own?

The announcement says users can “purchase and add” custom domains, but it does not document the process for domains registered elsewhere. It also does not specify supported registrars, extensions or transfer options.
