KeyLine

Secure terminal messaging for teams and developers

KeyLine is a command-line chat tool designed for people who prefer working in the terminal. It focuses on reliability, privacy, and simplicity. No UI layers, no tracking, no unnecessary features.

What KeyLine does

• Provides persistent chat from the terminal • Syncs messages in real time • Assigns each user a stable identity • Works out of the box without setup • Can be self-hosted if needed

KeyLine uses Supabase for storage and access control. Security is handled through database rules, not marketing promises. If you need true end-to-end encryption, self-hosting and custom logic are recommended.

Install

Quick run

npx keyline-cli@latest

Global install

npm install -g keyline-cli@latest

Using KeyLine

Once launched, KeyLine opens a shared chat channel.

Type messages normally and press Enter to send.

Security (v1.1.0)

KeyLine now enforces End-to-End Encryption (AES-256). When you join a chat, you must enter a Session Secret. This key is never sent to the server. Your peer must enter the same key to decrypt your messages.

Commands

• /help List commands
• /clear Clear the screen

• /nuke Disconnect and exit

Fun commands (optional):
