Tobasu

Tobasu (Transmit Only By Anonymous Shared Url) is a minimal, elegant content-sharing tool. It allows you to "send" (Tobasu means 'to fly' or 'to send' in Japanese) URLs from one device to another instantly, as long as they are on the same Wi-Fi network.

• Receiver: https://ryokokuga.github.io/Tobasu/
• Sender: https://ryokokuga.github.io/Tobasu/send.html

Caution

Demo Version Disclaimer The URLs provided at the top of this page are for demo purposes and utilize the PeerJS free public server.

• Stability: Since this is a shared public resource, connection speeds may vary, and service may be unstable during peak traffic.
• Privacy & Production Use: For users who require higher security, privacy, or reliability for daily use, it is strongly recommended to host your own PeerJS Server rather than relying on the demo environment.

■ Features

• Seamless Transfer: Instantly send URLs to other devices without manual configuration.
• Peer-to-Peer (P2P): Powered by PeerJS for direct device-to-device communication.
• Auto-Detection: Automatically detects the receiver on your network. No IP typing required.
• Network Bound: Designed to work exclusively between devices sharing the same public IP.

■ Components

The project consists of two simple interfaces:

• Receiver: A standby interface that prompts an approval dialog upon receiving content.
• Sender: A streamlined transmitter that auto-detects the active receiver on the same network.

■ Quick Start

1. Host the Files

Deploy the HTML files to any static hosting service or run them on a local server.

2. Launch Receiver

Open the Receiver on the target device (e.g., PC, Tablet, or TV).

• Status will show "● Ready on the same Wi-Fi".

3. Launch Sender

Open the Sender on your source device (e.g., Smartphone).

• Enter the URL you wish to share.
• Tap "Send Content".

4. Approve and Open

An alert will appear on the Receiver. Click "Open" to navigate to the shared link.

■ Power User Tip: The "Tobasu!" Bookmarklet

For the most efficient experience, use the Bookmarklet to send the page you are currently viewing without any manual copying.

Installation

1. Create a new bookmark in your browser's bookmark bar.
2. Set the Name to Tobasu!.
3. Paste the following code into the URL (or Location) field:

javascript:(function(){
    const SENDER_PAGE_URL = "https://ryokokuga.github.io/Tobasu/send.html"; 
    const currentUrl = window.location.href;
    const finalUrl = SENDER_PAGE_URL + "?url=" + encodeURIComponent(currentUrl);
    window.open(finalUrl, '_blank');
})();

■ Tech Stack

• Frontend: HTML5, CSS3 (Custom Variables, Flexbox, Keyframes)
• P2P Networking: PeerJS
• Signaling Server:
  • Demo: PeerJS Public Cloud (0.peerjs.com)
  • Production: Self-hosted instance recommended.
• Utility: ipify API

■ Usage Note

Note: Both devices must be connected to the same Wi-Fi network (sharing the same public IP address) for the automatic discovery to function correctly.
