opencord

Ephemeral chat servers that shut themselves down. Spin one up, share the invite link, chat, and it disappears.

Install

cargo install opencord

Or build from source:

git clone https://github.com/mcncl/opencord.git
cd opencord
cargo build --release

Usage

Start a server

cargo run --bin server -- --lifetime 2h

Output:

Listening on 127.0.0.1:8080 (lifetime: 120 minute(s))
Access code: XK7N4P
Invite link: ws://127.0.0.1:8080/?code=XK7N4P

Connect

Share the invite link. Each person connects with:

cargo run --bin client -- <name> <invite_link>

cargo run --bin client -- Alice ws://127.0.0.1:8080/?code=XK7N4P

Commands

How it works

• The first person to join is the host
• The server shuts down when: the lifetime expires, the host disconnects, or all clients leave
• Warnings are broadcast as the deadline approaches (10m, 5m, 1m, 30s)
• The host can extend the lifetime with /extend
• Access codes prevent uninvited connections
