We are building the open source chat layer for modern apps.
Your app needs chat. Ship it in 60s.
Get in 60s what takes sprints to build: chat infrastructure that lives inside your app.
Set up chat in your Next.js project using ChatPack.
Install chatpack. Create lib/chatpack.ts with ChatPack(), configure your database URL and secret, add the chat component to your page, and start sending messages.
Works with:
Up and running in two commands.
No account required, no hosted service to sign up for. Your database, your infrastructure, your users. Stays free forever.

One-to-one messaging with typing indicators and read receipts, ready on day one.
Everything messaging needs to feel real.
