Momento is the backend for a minimalistic, privacy-oriented, open source gallery app.
It works with PostgreSQL to store it's data and other than that it has no runtime dependencies.
The recommended way is to install via your package manager so it is better integrated with your default system monitor, logging facilities, etc. In near future a package will be available for installing via Alpine's apk.
You can however, build the binaries using make:
$ make $ doas make install
AGPLv3, see COPYING.
$ git clone https://git.eletrotupi.com/git/momento
