Local Content Share

Local Content Share is a lightweight self-hosted web application written in Go that provides a browser frontend and PWA for sharing and storing text snippets, files, and links on a local network. It uses a simple filesystem-backed data store and Server-Sent Events to keep clients synchronized in real time.

Key Features

• Store and share plain text snippets with view, edit, rename, and delete operations
• Upload and download files with multi-file drag-and-drop and clipboard paste support
• Built-in Notepad with Markdown edit and preview, auto-save, and cross-device persistence
• Link section for storing and sharing URLs in most-recent-first order
• Configurable per-item expiration (Never, 1 hour, 4 hours, 1 day, or custom TTL)
• Real-time client updates via Server-Sent Events (SSE)
• PWA support and fully local assets so the app works without external dependencies
• Files and metadata persisted to a local data directory (files/, text/, links.file, expiration.json)
• Distributed as multi-arch Docker images and standalone Go binaries for easy homelab deployment

Use Cases

• Quickly transfer screenshots, documents, or small files between devices on the same network
• Temporary pastebin for sharing code snippets, notes, or short text with configurable expiry
• Cross-device Markdown scratchpad for writing notes or drafts accessible from phone and desktop

Limitations and Considerations

• No built-in authentication or access controls; intended for trusted local networks or behind an auth-enabled reverse proxy
• Reverse proxies may interfere with upload progress visibility and can impose file size limits unless adjusted
• Data is stored on the filesystem in plain form; no built-in encryption, multi-user separation, or audit logs
• Not designed for public exposure or multi-tenant usage without added access control layers

Local Content Share is a pragmatic tool for easy, ephemeral content exchange within private networks and homelabs. It prioritizes simplicity, local-first operation, and minimal dependencies for quick deployment and use.
