Press information: SwarmSpan connects the clipboard and files on a Mac and Windows PC

October 2026 product information, pricing, review exercise and assets for SwarmSpan's local Mac/Windows clipboard and file-sharing utility.

For immediate release — October 8, 2026. This describes an available product; it is not an announcement of a new release today.

SwarmSpan is a desktop utility for people who use both a Windows PC and an Apple Silicon Mac. It shares clipboard items and transfers files directly between paired, awake computers on the same local network.

A developer may copy a stack trace on Windows and need it in an editor on the Mac, or finish a file on one computer and need it on the other. SwarmSpan provides a local handoff for that everyday problem. The clipboard has searchable history; clipboard and file transfers between paired computers do not require a hosted clipboard account or a cloud relay.

Availability and price

The Windows edition is a US$4.99 one-time website license for the buyer's own Windows PCs. The Mac App Store edition is a separate US$4.99 purchase through Apple. There is no subscription. Local store prices and tax may differ. Existing installations from before licensing continue working at no charge.

A review readers can reproduce

Pair the intended Mac and PC, keep both awake on the same network, and send a throwaway file. Open the received file, then compare its SHA-256 with the original. Return it to a new folder and compare again. A matching hash proves that file arrived intact; it does not prove a build or a test passed.

An October 8 operator demonstration completed a 145-byte Windows-to-Mac-to-Windows file round trip through the installed SwarmSpan MCP and verified matching original and returned SHA-256 hashes. This is a limited transfer demonstration, not a customer testimonial or a fresh-installation test.
