How to turn a ChatGPT or Claude chat into a real app: three ways compared
By Kinetropic, the maker of Koi Launch · Updated:
Short answer
Use a shareable-app connector such as Koi Launch for small apps you want to send as a link, in a browser or Telegram, for free. Use a full-stack builder such as Floot when the app needs a backend, database, custom domain or payments. Ask the AI for code and host it yourself only if you are comfortable with deployment and want full control.
What are the three ways?
A chat model can write an app, but something else has to run it. The choice is where that something lives: in a connector that hosts for you, in a full-stack platform, or in your own hosting.
| Topic | Shareable-app connector (Koi Launch) | Full-stack builder (Floot) | Code you host yourself |
|---|---|---|---|
| Best for | Quizzes, trackers, games, study and family tools | Products with a backend, database, domain or payments | Anything, when you want full control |
| Who hosts it | The connector | The platform | You |
| Skills needed | None | None to low | Deployment and maintenance |
| Custom server code | No | Yes | Yes |
| Opens in Telegram | Yes, as a Mini App | Not covered here | Only if you build it |
| Starting cost | Free (Go: $4.99 a month) | Free (Pro: $25 a month on 1 Nov 2026) | Depends on your hosting |
When is a shareable-app connector enough?
When the app is for people you can send a link to, stores a score, a streak or a list, and does not need server logic. Koi Launch gives you saved progress, shared lists, versions, rollback and a stable link, free.
When do you need a full-stack builder?
When the app needs its own database, server-side rules, a custom domain, payments, emails or app-store publishing. See the Koi Launch vs Floot comparison for a side-by-side.
When should you host the code yourself?
When you want complete control over the stack, already know how to deploy, and accept the ongoing work of hosting, security updates and storage. A chat can write the code, but you operate it.
How do you start with Koi Launch?
Connect it to ChatGPT or Claude on the connect page, describe your app, preview it, and publish. The first app takes about five minutes.
Frequently asked questions
Can ChatGPT or Claude publish an app by itself?
A chat can write the code, but it needs a connector or platform to host the app and give it a link. Connectors such as Koi Launch provide that.
What is the cheapest way to share an app made in a chat?
A shareable-app connector. Koi Launch is free to make and share apps, with optional Go at $4.99 a month.
Which option suits a non-programmer?
Koi Launch and full-stack builders such as Floot are both built for chat-based creation. Hosting the code yourself requires deployment skills.
Can I move an app between options later?
There is no one-click import, but you can ask your AI to rebuild the idea on another platform.
