Meridian is a private, local-first household financial command center. All your data stays encrypted on your own machine — nothing is uploaded anywhere.
This repository hosts the installers only. The source code is private.
Grab the latest installer for your operating system from the Releases page:
- macOS (Apple Silicon or Intel): download the
.dmg, open it, drag Meridian to Applications. - Windows (64-bit): download the
-setup.exeand run it.
Once installed, Meridian keeps itself up to date automatically — you won't need to download again.
Because the app isn't signed with a paid developer certificate, your OS will warn you the first time:
- macOS: right-click Meridian → Open → Open. If it still refuses ("damaged / can't be
opened"), run once in Terminal:
xattr -dr com.apple.quarantine /Applications/Meridian.app - Windows: on the SmartScreen prompt, click More info → Run anyway.
This is a one-time step per install; updates apply silently after that.
On first run you'll pick a name, set your own password, and either start solo or create/join a household. Household members sync through a shared cloud folder and are linked by a one-time invite code — there is never a shared password.
