Build Full Stack Apps for FREE Without Coding with Antigravity

Описание: Prompt Used to Finalize the App (at the end):

You are fixing a Next.js 15 application that is being deployed on Hostinger Cloud with Node.js, not Vercel.

Context:
The “Unsupported framework” error comes from Hostinger’s onboarding wizard.
The wizard does not support raw Next.js repositories.
The app will be deployed via the Hostinger Node.js panel, not via file upload.

Constraints:
Must run with:
npm install
npm run build
npm run start -p 3000
Node.js version: 20
No Edge runtime
No Vercel-only APIs or helpers
No static export required

Tasks:
Confirm that no changes are needed to fix the “unsupported framework” onboarding error.
Verify the app is compatible with classic Node.js hosting.
Only suggest changes if something would break on Hostinger Cloud.

Output rules:
Say “NO CODE CHANGES REQUIRED” if applicable.
Otherwise, list minimal edits only.
Do not mention Vercel or static hosting.

Built a full-stack AI web application using Google’s free cloud coding platform, Anti-Gravity.

In this video, I build UniChat, a unified AI chat app that lets you access and switch between multiple large language models like ChatGPT and Claude from a single interface.

We focus on building real, production-ready functionality instead of just a fancy UI.

What you’ll learn:
– Full-stack AI app development from scratch
– Building a multi-LLM chat application
– Using OpenRouter to connect multiple LLM APIs
– Backend setup with Supabase MCP
– Handling real-world LLM errors, latency, and model routing
– Deploying a web app on Hostinger with a custom domain
– Live demo and ideas for scaling, monetization, and new AI features

Perfect if you want to build, deploy, and scale real AI products, not just prototypes :)

Note: “Free” refers to using the Antigravity platform itself, which does not require payment. However, if you choose to integrate third-party services or APIs, those services may have their own usage costs.
