Pubvay is a design tool for laid-out, multi-page digital publications — newsletters, briefs, zines, reports, decks — and a portable format to put them in.
You compose in the browser. What comes out is a single
.zdx file that opens like a finished publication in any
browser, on any machine, with no app, no account, and no internet
connection.
Place blocks on a page instead of stacking them in a feed. Multi-select, drag, distribute, snap. Named paragraph styles and a type scale keep a long document consistent.
Text, images, layout, fonts and the renderer itself are packed into the
.zdx. Email it, drop it on a drive, hand it over on a stick —
it renders the same everywhere.
Publish a dispatch and share a short URL. Readers get the same layout in the browser, and can pull down the file if they want to keep it.
No platform in the middle of you and your readers. The file works after the tab closes, after the subscription lapses, after we're gone.
.zdx?Nothing exotic. It's a zip with a predictable shape:
index.html — the renderer, self-containedmanifest.json — pages, styles, metadata
Rename it to .zip and every piece is right there, in formats
that will still open decades from now. There is no proprietary blob to be
locked out of.
