You Vibe-Coded Something. Now Where Do You Host It?

AI Summary: This article explains how to choose hosting for a vibe-coded app by starting with its architecture rather than a hosting brand. It breaks an app into frontend, backend, database, object storage, serverless functions and environment variables, and explains when static hosting falls short. A table maps project requirements to suitable architectures. It also covers serverless limits, why secrets in frontend code are exposed, keeping functions close to your data, and testing in preview environments before production.

If your vibe-coded app runs in the browser, 99helpers can put it online at its own link in seconds.

With vibe coding, an idea can be turned into a working application from a prompt quickly. But the more difficult question is where to host a vibe-coded app when it needs to run reliably for others. Hosting is not as simple as finding a place to store files; it is a question of matching the infrastructure to the runtime, data and security needs of your software.

An application that makes use of AI API calls, databases, or payments will have entirely different hosting needs than a project that runs in the browser. So it is better to look at the architecture of the application first, not the hosting brand.

Identify What the Application Actually Needs

Consider what happens when a visitor is using the app. A frontend-only project can run inside the browser, but a full application will require server-side code to handle requests, access private APIs or authenticate users.

There is a clear distinction to be made:

• Frontend: The HTML, CSS, JavaScript and frameworks

• Backend: API endpoints and application logic on the server

• Database: Where persistent data is stored

• Object storage: For uploads, documents and images

• Serverless functions: For short-lived backend tasks

• Environment variables: To hold sensitive values and configuration

Cloudflare’s platform, for instance, covers both static assets and server-side work via Workers, with Pages Functions offering dynamic capabilities without a dedicated server.

When Static Hosting Falls Short

In many ways, a vibe-coded app is software in disguise, even if it appears to be a website. Consider a booking system, for instance. The application will have to take a request and verify the user, put the booking in the database and issue a confirmation, all before the browser gets its result.

While the interface is handled on the frontend, anything as sensitive as payment credentials or secrets is kept on the server where it belongs.

In such cases, you need a conventional backend or serverless functions. Netlify Functions, for example, can be deployed with the rest of a project to provide those backend functions as HTTP endpoints.

Choosing the Right Architecture

It is easier to make a hosting decision when the requirements are clear.

Modern platforms tend to put these components together; Netlify offers Blobs, scheduled and background functions and database integrations as part of its core offering.

Serverless as an Alternative

There is no need to rent and manage a virtual machine. With serverless, the provider manages the infrastructure while your backend code runs in response to events. This suits a small project when you host a vibe-coded app, allowing it to start with a handful of endpoints and expand.

One should be mindful of technical limits, however. Netlify puts a 60-second cap on synchronous execution for standard Functions (though background functions have more flexibility) and there are payload restrictions. A long-running job does not belong in a normal request function.

Frontend Secrets Are No Secret

AI-generated code can be tempting to leave as it is, but a private key in a const declaration is visible to anyone who inspects the browser.

const API_KEY = "your-private-key";

The proper way is for the frontend to call your backend endpoint, which in turn gets the secret from an environment variable and talks to the external service. Netlify accommodates this for serverless functions.

Location Matters for Performance

Do not let the choice of frontend hosting be the only consideration. If a serverless function in one region is making calls to a database in another, every operation has to cross that network. On a data-heavy app, that affects response time. Netlify notes that deploying functions closer to your data sources reduces round-trip latency.

This becomes particularly important when you host a vibe-coded app that performs frequent database reads, writes or API requests.

Test in Preview First

Because vibe-coded applications are prone to rapid change, there is a need for testing in isolation. The way to go about it is to follow a path from development through to a preview and on to production.

Before putting a new version live, run it by the preview environment first. See how the error handling holds up, verify the API responses and payments. Should you have to, both Netlify and Cloudflare Pages will let you roll back.

The Bottom Line

Do not expect to come across a hosting architecture that fits every vibe-coded project. While something meant for the browser can be put on static infrastructure, the moment you have users and external APIs in the mix, your stack has to be capable of dealing with authentication, execution limits and failure recovery.

So the real question is not “Where do I host my code?” but “Which parts of the app have to run where?” Once you have an answer to that, the platform will align with what the runtime demands. That is what matters when you are hosting this kind of application.

Hosting the Frontend With 99helpers

For projects that run entirely in the browser, 99helpers is the fastest way to get them in front of people. Drop in the built files or a ZIP, choose an address, and the app is live over HTTPS with no pipeline to configure. Each new version goes to the same address and earlier ones are kept, so rolling back is a click. Your AI coding assistant can even publish directly to 99helpers through the MCP server. If the app needs a backend, database or secret keys, host those parts on a serverless or application platform as described above, and call them from the frontend you host on 99helpers.
