Links
Hand anyone a button that gives them their own copy, or make a throwaway link for this tab.
Get your own copy
one click, any visitorPress a button and that host clones the launcher into your own account and builds it. You end up owning a real site at your own address. You sign in with your account, not anyone else's.
Owner setup
onceThe buttons above need one public repository to copy from. Point them at it and they start working for everybody who lands on this page.
Make that repository
needs a tokenIf you do not have one yet, this uploads the files to a fresh GitHub repository and switches on Pages. Do it once, paste the resulting address above, and you never touch a token again — the buttons only need the repository to be public.
github.com/settings/tokens → classic → tick repo. Kept in this browser, sent only to api.github.com. Revoke it when you are done.

8What each one actually is
The buttons at the top. Each one hands the visitor to a host's own setup flow with your repository already filled in. They sign in with their account, the host copies the repository into it and builds the site, and they walk away owning it. Netlify and Vercel both clone into the visitor's own Git provider before deploying. Nothing of yours is handed over and nothing of theirs comes back to you.
It is worth saying why it works this way rather than the obvious way. Putting your GitHub token in the page so a visitor could deploy on your behalf would give that token to every single visitor — it takes seconds to read out of the page source, and a token with the repo scope can create, rewrite and delete anything on your account. Routing through the host's own sign-in is both safer and fewer steps for them.
Portable file. A small .html file you can carry on a stick or email. It points back at your site rather than containing it, so the site has to stay up.
Blob link. Unique every press and looks like nothing, but it only exists inside this tab. Close the tab and it dies, and it will not open for anyone else.
about:blank. The same document in a blank window, with no address to copy at all.
