OpenHive — Open-source Slack alternative built with shadcn/ui

[arseneHuot]

Hi! I built OpenHive, an open-source self-hosted Slack alternative that uses shadcn/ui extensively for the entire UI.

shadcn/ui components used

The app uses many shadcn/ui components including Button, Input, Dialog, DropdownMenu, Avatar, Badge, ScrollArea, Tooltip, Separator, Tabs, and more — all customized with Tailwind CSS for a clean messaging interface.

Features

• Channels, DMs, threads, mentions, reactions
• File uploads and pinned messages
• Video/audio calls with screen sharing
• Real-time activity panel
• Setup wizard

Tech Stack

• Next.js 14 (App Router) + TypeScript
• Tailwind CSS + shadcn/ui
• Zustand for state management
• Supabase for the backend
• LiveKit for WebRTC calls
