sendit!

A simple, high-performance, drag-and-drop file transfer tool for local networks. If you like the project please remember to star so others can findit.

Narrative of Virtues

Open the app, automatically discover peers, drop a file onto the app window and publish instantly to sendit peers. No server, no configuration, just simple and efficient file transfer over modern standards-based peer-to-peer plumbing.

Virtues

• Straightforward: Launch & automatically discover other sendits, no installation, setup or configuration required
• Drag-and-drop: Drop a file -> transfer to others
• Large file support: Send large files 5GB+
• High Performance: Built with Zenoh & Rust for fast app processing and on-wire transfer
• Networking Options: Configurable direct connections and multiple data transport types - UDP, TCP, WS, TLS
• Dark/light mode: Light mode is almost as delightful as Dark

To Start Quickly

Presumptions

• Rust 1.70+

Build & Run

git clone <repository-url>
cd send_it
cargo run --release

The app auto-connects in peer mode on port 7447 with multicast discovery. Drop a file to send it.

Useit

Sending Files

1. Launch sendit
2. Wait for connection (green dot in toolbar)
3. Drag a file onto the central drop zone
4. File is published automatically — topic key is derived from the file's parent directory and filename (e.g. Documents/photo.jpg)

Receiving Files

1. Files from other peers appear in the topic tree (left panel)
2. Click a topic to see details in the slide-out right panel
3. Click "Export Payload" to save the file locally
4. For chunked files, progress shows completion status before export

Settings

Click the gear icon (top of left panel) to access:

• Connection: Transport, address, port, peer/client mode, connect/disconnect
• Subscriptions: Subscribe to key expressions, manage active subscriptions
• Query: Send queries to the network, configure timeouts
• Queryable: Enable a service that responds to queries with locally stored data
• Memory & Performance: Memory limits, message limits, rate limiting, deduplication

Connection Modes

• Peer mode (default): Multicast discovery, mesh networking. Leave address blank for auto-discovery, or specify tcp/ip:port for specific peers.
• Client mode: Connect to a Zenoh router at a specific endpoint.
