Open source
Read every line
Slate is open source under the MIT license. The app, this website and the desktop app are all here. Check what it does, or build on it.
Connections
Device to device
Friends connect directly with WebRTC, which encrypts every connection. Free public relays only pass along an encrypted introduction.
Storage
On your devices
Messages and friends are saved in your browser’s storage. There’s no Slate database of chats.
Server
Only for supporters
The one server-side piece checks supporter status by friend code and handles Stripe checkout. See src/index.ts.
