Spectersync Local
The same content engine that powers the hosted workspace, running entirely on your own machine.
Spectersync Local pulls your Shopify, WordPress, Ghost, or Webflow content into a folder of plain markdown on disk, watches it for changes, and pushes your edits back — with dry-run previews and conflict detection in the loop. Your post bodies, drafts, and folder structure never touch our servers. Point any AI tool, editor, or script at the folder; the round-trip is handled for you.
There are two doors.
Spectersync Core — the desktop app
A signed, notarized macOS app with automatic updates and support — the engine underneath is the same one that’s open source. No longer sold to new customers; existing licenses and updates keep working.
Spectersync DIY — free and open source
The AGPLv3 edition. Inspect it, fork it, build it yourself, and run your own local sync for free, forever. No signed installer, no commercial auto-updates, no priority support.
Not sure you want to self-host?
The fastest way to start is the hosted workspace — no install, no build, and 400 free credits when your workspace opens. The local editions are for people who specifically want the engine on their own hardware, with their content as files on disk.
