Guides for putting your app online
You built something that works on your computer. These pages answer what people ask next, in plain words.
Last checked 17 October 2026
Each guide answers one question people ask once their app works on their own computer. They're written for people who build with Claude Code and don't write code themselves. When a guide says what fline does, it matches what fline does today.
- How to get your Claude Code app online and share it Your app needs a host, a place online where it runs with a link anyone can open. Connect Claude Code to a host such as fline, ask it to put your project online, then send people the link.
- Can Claude host my website? It depends where you made it Partly. On paid plans, you can share a page Claude makes as a link, but it isn't built to host a whole app, like the one Claude Code built in your project folder. What you can do depends on where you made it.
- My app only works on my computer. How can other people use it? The preview runs on your own computer, so only you can open it, and it stops when your laptop sleeps. For other people to use your app, a copy has to run online at a host, with a link you can send.
- Is it safe to give Claude Code your API keys? Claude Code needs to know your app uses a key, not the key itself. It can read the chat and your project folder, so keep live keys out of both and type them on your host's private page.
- Do I need a database for my app? A plain answer You need a database if your app has to remember something after someone leaves the page, like sign-ups, bookings or messages. If it only shows information that doesn't change, you don't.
