Blog · September 12, 2026 · Rich Chetwynd A Claude artifact lives in your chat. Emailing the HTML is not a real share. Here is how to host it so your team can open it like a normal app.
Quick answer #
If you built something useful in Claude (a financial model, a calculator, a tracker) and the only way to share it is pasting HTML or screenshots, you need to host it as a real app. Put it on a private server, give it a URL your people can open, and let them sign in. That is what Croft is for. You do not need to know how to code or manage servers.
The problem with “just share the artifact” #
Claude Artifacts (and ChatGPT Canvas, and similar previews) are brilliant for building in the moment. They are a poor way to run a tool for a team:
- The preview lives in your chat. Colleagues cannot open it on their own.
- There is usually no lasting database . Numbers vanish when the session ends.
- Emailing an
.htmlfile means every person has a different copy, nothing is saved together, and updates mean another attachment. - A public paste or public host puts internal numbers on the open internet unless you invent login yourself.
So the model worked. The sharing step failed.
What “host my AI app” should mean #
For a business tool, hosting is not “get any live URL.” It is:
- A link the team can open in a browser
- Sign-in for your people , so strangers cannot wander in
- A database so the model remembers inputs and results
- Backups and a way to undo a bad change
- A path to update by chatting again, without starting from zero
If you do not care about coding, the host should handle the dull parts: HTTPS, deploys, and keeping the server online.
Artifact vs hosted app #
| Need | Claude artifact | Email the HTML | Public host | Croft |
|---|---|---|---|---|
| Team can open their own link | No | Fragile copies | Yes | Yes |
| Shared saved data | No | No | Extra setup | Included |
| Private to your people | Chat-only | File chaos | You build login | Built in |
| No devops required | N/A | N/A | Sometimes | Yes |
| Keep iterating with AI | In chat only | Start over | Varies | Connect Claude and keep going |
How to get there with Croft #
- Get a croft (private server) and connect Claude , or useCroft Build if you prefer not to connect an assistant yet.
- Ask Claude to deploy the artifact to your croft as an app.
- Invite the people who should use it. They open a normal URL and sign in.
- Keep chatting to change the app. Deploys and rollbacks stay on the server.
More on the product path: From artifact to app. You still do not need to learn nginx, Docker, or “how to deploy.” The point of Croft is that the assistant can ship it for you.
FAQ #
Can I just send the HTML file?
You can, once. Then someone edits a number, another person has an old copy, and nobody has a shared source of truth. That is fine for a demo. It is not fine for a financial model your team uses every week.
Do I need to be technical?
No. If you can chat with Claude, you can ask it to deploy to Croft. The people who get the most from this are subject-matter experts (finance, ops, sales), not platform engineers.
Is this the same as putting it on Vercel or Replit?
Those are strong for public products. For an internal model or tracker, you usually want a private server and team sign-in by default, not a public URL you must lock down after the fact. See also

What about ChatGPT Canvas or other previews?
Same job. A preview in chat is not a team app. Deploy it to Croft when you want a lasting URL, saved data, and people you invite.
