ButterBox is a portable, fully offline device (usually running on a Raspberry Pi). When you turn it on, it creates its own local Wi-Fi network. Anyone nearby can connect and access a set of tools without any internet connection:

• An offline app store (based on F-Droid)
• File, video, book and educational content sharing
• And most importantly — secure encrypted chat

What makes this project especially powerful is its deep integration with #deltachat The ButterBox team uses the MadMail server to run a local Chatmail Relay inside the box.

Users can create an offline account with just a single QR scan or one tap and immediately start using fully end-to-end encrypted messaging. Even when there’s no internet at all, messages, groups and files can be exchanged securely between people.

This is where DeltaChat really shines: decentralized, no central servers, real encryption, and designed for difficult conditions.
Combined with ButterBox, it becomes a genuine tool for secure communication during internet shutdowns, in remote areas, or in crisis situations.

It’s a pity that this project still isn’t widely known or deployed in Iran. The good news is that it’s completely open source and can be set up with a regular Raspberry Pi and an SD card. Pre-built images are also available, which makes the process even easier.

For anyone interested in privacy, offline communication, and tools that keep working when the internet goes down, ButterBox is one of the most valuable projects around right now.
