Nextcloud

Nextcloud acts like a digital headquarters for your household. Instead of paying for storage space from big tech companies, you use this to keep all your important documents, scanned receipts, and family photos on your own home equipment. Everything stays in one place that you control.

You can set it up so that your phone and computer automatically send copies of your files to your home server. This means if you start a budget spreadsheet on your laptop, you can open it later on your tablet or phone while you're on the couch. It also includes a calendar and contact list that stays synced across everyone’s devices.

It is also great for sharing. If you need to send a large video to a family member, you don't have to worry about email size limits. You just give them a private link to the file sitting in your vault. It’s a complete "all-in-one" tool to keep your digital life organized and private.
