Your agent makes a page.
You get a live link.
It lasts about a month.
Your agent hands you a link to open, not a file to find: an unguessable URL — a single page, or a whole gallery of HTML + images — that expires on its own.
Get started.
Mayfly is internal — sign up with your @carved.com email. Type the code, and your agent gets a one-line install link. If you have signed in before, Mayfly gives you the same token unless it was revoked.
Your pages.
Pages your agents create with this token appear here within seconds. Live pages stay on top; the history below keeps the metadata after content expires.
No live pages yet. Paste your install link to your agent; new pages will land here and then move into history when they expire.
History
No page history yet. Pages created from this login onward will be listed here.
How it works.
-
01
Paste the install link
Sign in above, then paste the one-line link to your agent: Claude Code, Codex, Cursor. It sets itself up once.
-
02
Ask for a page
Your agent builds it as one self-contained page and posts it.
-
03
Get a link
A live URL that opens in any browser. When it expires, there’s nothing to take down.
show me last week’s deploys as a chart
done. built it as one page and posted it:

See a page for yourself.
Four real ones, published by us and pinned so they never expire. Nobody else’s pages are linked from anywhere — these are ours.
-
“chart last week’s deploys”
One page, one chart, and the two failures explained under it.
-
“what’s failing in CI?”
A test-run report: three failures, each with the error and a likely cause.
-
“mock up the billing settings”
A click-nothing mockup you can open on your phone and react to.
-
“make a landing page for our smart toaster”
A whole dark-mode marketing site for a product that doesn’t exist.
Private by construction.
No login to view. Anyone you send the link to can open it.
-
the url is the only key
22 random characters and no directory. A link you never shared might as well not exist.
-
noindex, no-store
Search engines are told to stay away, and caches are forbidden to keep copies.
-
gone in about a month
Expired pages are deleted on the spot. No backup holds a copy.
Sized for sharing, not hosting.
Mayfly hands someone a living page; it isn’t a place to host a site. Budgets are per account, over a rolling 24 hours.
-
25 mb per page
One self-contained file — or an HTML page bundled with the images and assets it links to.
-
200 pages a day
Enough for a long day of show-me’s, swarm after swarm.
-
500 mb a day
A byte budget alongside the page count. It keeps publishing instant for everyone.
