Hearth: Self-Hosted Multi-User AI Chat App for Households on OpenClaw

Open-Source Multi-User AI for Families

Developer Warrence Han has released Hearth, a self-hosted household AI chat application built on top of OpenClaw. The project addresses the limitation of single-user AI interfaces by creating a multi-user environment where each family member maintains separate conversations, accounts, and privacy controls.

Core Features

• Multiple chat conversations per person
• Multi-user household support with individual accounts
• PIN + biometric login
• Private chats with role-based access (owner/member)
• Reminders functionality
• Real-time streaming with stop button
• Model presets (fast/deep per conversation)
• Attachments, image generation, text-to-speech
• Mobile-first dark theme PWA installable on phone
• Self-hosted with optional HTTPS via Caddy
• One-command installer that handles deployment

Technical Implementation

The application uses Vue 3 + Quasar for the frontend, NestJS for the backend, PostgreSQL for data storage, and an OpenClaw plugin for AI routing. The developer reports that their family is using it daily, though it's still in early release with ongoing development.

The project aims to address the gap in household-focused AI tools where most current products are designed for individual use. By keeping context and memory within the household rather than on external platforms, Hearth provides families with control over their AI interactions.

The source code is available on GitHub for those interested in self-hosting or contributing to the project.
