Use ChatGPT Sites when you want to turn a prompt and source material into a lightweight website or app, refine it in ChatGPT, and publish it through that workflow. If your AI has already produced a project folder or repository—or your project depends on hosting features Sites does not support—a code deployment route such as Netlify may fit better. Vercel is another possible domain and deployment route, but the documentation considered here establishes its domain workflow, not a full comparison with the other options.
The right choice depends on what your AI built and what you need to control: the starting format, review and release process, domain, technical requirements, and workspace or data policies. There is no established universal winner on price, performance, or portability.

What each option is designed to handle
| Option | Starting point and workflow | What the cited documentation establishes |
|---|---|---|
| ChatGPT Sites | A prompt, brief, or source content. Create and refine the site in ChatGPT, review a private preview, then publish. | OpenAI describes Sites as a way to create, edit, preview, publish, share, and manage interactive websites and lightweight apps. The workflow is documented in OpenAI Help Center’s “Creating and using ChatGPT Sites.” |
| Netlify | Existing generated files or a project folder, or an AI tool that can work with Netlify. Deploy by drag-and-drop, through an AI-tool workflow, or with the CLI; Git-connected projects can deploy from pushes. | Netlify documents preview and production deploys, continuous deployment from a connected Git repository, and previews for changes from supported AI agent runs. See its AI deployment quickstart and deployment documentation. |
| Vercel | A project needing a deployment route and domain configuration. | The cited Vercel documentation explains adding and configuring a custom domain, and says users without a domain can purchase one through Vercel. That evidence alone does not establish a full feature comparison with Sites or Netlify. |
These are different workflows, not interchangeable labels for the same process. Sites is the clearest fit when the prompt and iterative creation happen inside ChatGPT. Netlify’s documented routes begin with files, a project folder, an AI-tool integration, or a Git repository. The available documentation does not establish that one route is always cheaper, easier, faster, or more portable.
Choose based on your project and release workflow
Start with a prompt and want a managed publish flow
Choose ChatGPT Sites if the project is a lightweight site or app that fits the supported environment, and you want to describe what you need, inspect a private preview, iterate, and publish from ChatGPT. OpenAI says you can save a version for review before deployment; deploying creates a production URL. That gives you a review point before changing what visitors see.
Already have code or a project folder
Consider Netlify if your AI has produced files that you want to deploy as a project rather than recreate through a prompt-led workflow. Its documentation describes drag-and-drop deployment, an AI-tool route, and the CLI. If you connect a Git repository, pushes can trigger continuous deployment. Netlify also distinguishes preview deploys from production deploys, which can suit a workflow where changes need review before release.
Need a domain-focused deployment route
Vercel is a possible alternative if you are evaluating a deployment provider and need to configure a custom domain. The documentation cited here supports that domain use case, but does not supply enough detail to compare Vercel’s complete workflow, technical capabilities, or costs against ChatGPT Sites and Netlify. Check the current provider documentation against your project requirements before choosing.
Check domains, eligibility, and technical requirements
ChatGPT Sites access and limits
OpenAI’s current help article describes Sites as a public beta for ChatGPT workspaces, Plus, and Pro. It says Sites is not available on Free or Go; rollout and workspace configuration can also affect account access. Beta use is included up to plan-specific limits, which can change. Reaching a limit may affect site creation, storage, or whether a high-usage site remains public, so check the Sites experience for the limits that apply to your account rather than relying on a static cap.

For a custom domain on ChatGPT Sites, you must already own the domain and be able to change its DNS records. OpenAI says custom domains are not available in Enterprise workspaces at launch. Vercel’s cited documentation describes adding and configuring a domain and offers purchase through Vercel for users who do not own one. These are distinct starting requirements: confirm both domain ownership and workspace eligibility for the route you intend to use.
Runtime and data requirements
OpenAI warns that some frameworks, private networks, databases, background services, and hosting patterns may not be supported by Sites. Treat that as a reason to verify your specific dependencies, not as proof that every project using one of those categories will fail. If the project relies on a particular framework, database, network connection, or background process, check whether that exact implementation works on the destination before committing.
OpenAI also says Sites does not support data residency or inference residency at launch. If either is a requirement, that constraint may rule out Sites; verify the requirements and current capabilities of any alternative with its provider rather than assuming a different host meets them.

A new Site starts with restricted access. Depending on account and workspace settings, audiences can include the owner or administrators, selected users or groups, workspace members, or the public when public publishing is enabled. External named viewers may be possible without making a Site public.
For Enterprise workspaces, public publishing is off by default. An administrator must enable it and grant access through role-based controls. Connected-app permissions are separate: workspace approval does not automatically let a Site access every member’s data, and each visitor authorizes their own connection under existing app permissions. If your project needs public access or connected apps, confirm those controls with the workspace administrator before building your release plan.
Review the site and its content before release
OpenAI advises creators to review a private preview before sharing or publishing, especially when a Site contains confidential, sensitive, or third-party material. Review whether the site behaves as expected and whether its content is appropriate for the audience you plan to grant access to. OpenAI also says creators are responsible for their Site and its content, including visitor-submitted content and relevant legal compliance; publishing through a platform does not itself establish compliance.
A practical decision checklist
- What do you have now? A prompt and brief point toward Sites; an existing project folder or repository makes a code deployment path such as Netlify relevant.
- How should changes go live? Sites offers a private preview and an explicit deployment step. Netlify documents preview deploys and production deploys, plus Git-triggered continuous deployment for connected repositories.
- What domain do you need? For Sites, verify that you own the domain, can change DNS, and are using an eligible workspace. For Vercel, consult its current domain documentation for setup and purchase details.
- Does the project need a particular runtime or data arrangement? Check the exact framework, database, private network, background process, and residency requirements against the current destination documentation.
- Who can publish and view it? Check workspace settings, administrator controls, intended audience, and any connected-app authorization before relying on public sharing.
For a lightweight project that fits Sites’ runtime and account controls, prompt-led iteration and managed publishing make it a sensible starting point. When the AI has already produced files and you want a documented upload, CLI, AI-tool, or Git-linked deployment route, Netlify is a concrete option to evaluate. Consider Vercel when its documented domain workflow is relevant, while assessing its broader fit from current documentation for your project.
