Architecture

This page collects architecture and design decisions for Blip.

Backend

Protocols

Public facing GraphQL APIs
Server-to-server comms over gRPC (protobuf)

Storage

Phase 1 probably sqlite
Phase 2 add a connector for a real db? maybe postgres?

Features

servers ("guilds")
channels
threads?
dms?

Encryption

openssl?
age?
some other lib??

Client

Protocols

Talks to BE over GraphQL

Storage

UI Framework

Tauri? unless something else comes
client core lib maybe? TUI client?

Features

text chat
user profiels
late stage: voice and screen share

Encryption

E2EE
only client-to-client can decrypt the message content, server never sees it
how to handle user keys?
