Hearth is a group chat that lives on your NAS โ not a company's cloud. No caps on photos or video, no accounts, and nobody reading your messages but the people you invite.
Every other chat app rations your space and mines your messages. Hearth can't โ because it's running on hardware you own.
Drop a 4GB video or a thousand full-res photos. There's no upload cap, no "upgrade for more storage" โ it's just your NAS.
No accounts, no phone numbers, no company in the middle. Your messages live on your box and can't be sold, scanned, or leaked in someone else's breach.
Send a link. They open it, pick a name, they're in. Make channels however you want. No sign-ups, no friction.
Install it to your home screen, get push notifications โ it feels like a real messenger, because it is. iPhone and Android.
Jump into a voice or video call with everyone by the fire โ peer-to-peer, through your own server.
No subscription for the chat itself, no rug-pull, no shutdown email. As long as your box is on, your Hearth is lit.
Hearth is a thank-you for backing SparkBox โ one of the exclusive things you get for funding the project. Back it once, and it's yours.
