Databag

Databag is a self-hosted messaging server and set of clients focused on private communication using end-to-end encryption. It provides direct messages and group chat, with an emphasis on keeping message content encrypted so the server primarily stores ciphertext.

Key Features

• End-to-end encrypted messaging for direct and group conversations
• Web client plus native clients (project provides multiple client options)
• File and media sharing within conversations
• Multi-user server with account management
• Designed to minimize server-side access to plaintext message content

Use Cases

• Private team or family chat where the server operator should not read messages
• Small organizations that need an internal messenger without relying on SaaS
• Secure group discussions with sharing of attachments and media

Limitations and Considerations

• Smaller ecosystem than mainstream messengers; integrations and federation may be limited depending on client/support
• Feature set and client maturity may vary across platforms

Databag is a practical option for running your own encrypted messenger when you want a simple, controlled deployment and encrypted-by-default conversations. It fits best for small groups that value privacy and can standardize on the supported clients.
