SpreadPaper 1.10.0: new address, separate repositories

[rvanbaalen]

SpreadPaper takes one photograph and spreads it across every monitor on your desk, carrying the picture on behind the bezels instead of starting it again on each screen. It is free, open source, and native to macOS. This release is 1.10.0, and the project has moved house: the website now lives at spreadpaper.app, in its own repository.

A wallpaper here is one of three things: a single still image, a light one paired with a dark one that follows the system appearance, or up to sixteen images on a schedule through the day. Whichever you pick, every monitor gets its slice of the same picture, and they all change together.

Two repositories instead of one

The app lives in spreadpaper/SpreadPaper. The site lives in spreadpaper/website. They release on their own schedules, so a new SpreadPaper version now means the app itself changed — a headline reworded on the site no longer arrives as an update with nothing in it.

The new address, spreadpaper.app

The site moved from spreadpaper.github.io/SpreadPaper to spreadpaper.app, rebuilt on Astro and served from Cloudflare's edge. The pages are smaller, and the address is one you can say out loud.

Old spreadpaper.github.io links forward to it, so anything you have bookmarked still lands in the right place.

What is in 1.10.0

Rendered files are tidied up properly. SpreadPaper writes one image file per display. Renders and folders that no display or preset could reach any more were being left behind; they are now collected. If you have been using SpreadPaper across several monitor arrangements, this reclaims the disk space they were holding.

The release also carries the repository split and the move to the new domain.

Fixes since 1.8.0

If you are coming from 1.8.0 or earlier, the last few releases were mostly repair work — nineteen fixes. The ones most likely to have affected you:

• Drag and drop works in the wizard and the editor
• The gallery fills in as thumbnails arrive instead of blocking on all of them
• Renders that other desktops still point at are kept rather than deleted
• Schedule start times are picked from short hour and minute menus
• Dynamic HEIC files are written straight to disk, and a count mismatch is reported instead of passing silently
• SpreadPaper asks for read-only access to the files you pick, not read-write
• Icon buttons are named, text scales, and every string is localizable
• The update checker survives HTTP errors, odd tags and prereleases

Full detail is in the changelog.

Download, and what it needs

Download SpreadPaper — DMG or ZIP. macOS 15 Sequoia or later, on an Apple Silicon Mac. Free and open source under the MIT licence.

SpreadPaper is not signed with a paid Apple Developer ID, so macOS will stop the first launch. The download section on the site shows both ways through it, and it only happens once.
