Architectural Principles: Why Browser-Native WebRTC Wins
Traditional file sharing and synchronization utilities force users into heavy client installations, driver updates, and cloud subscriptions. Textunnel re-architects cross-device data transmission by moving the entire stack into standard web browsers using WebRTC DataChannels.
Zero Cloud Retention
All data streams directly through ephemeral volatile memory buffers, leaving zero footprint on intermediate servers.
Local Router Bandwidth
Payloads bypass asymmetric public internet upload speeds and utilize full local Wi-Fi bandwidth up to 120MB/s.
End-to-End Cryptography
DTLS 1.3 encryption keys are negotiated directly between peer browsers, preventing man-in-the-middle inspection.

Frequently Asked Questions
Are all productivity tools on Textunnel 100% free to use?
Yes. Every tool in our suite is completely free with no subscriptions, paywalls, or hidden file size caps. Everything operates using client-side WebRTC technology.
Do I need to install any software, browser extensions, or mobile apps?
No. All Textunnel tools execute natively inside modern web browsers (Chrome, Safari, Firefox, Edge). There are zero app downloads, driver setups, or background daemon installations required.
Are files or copied clipboard texts uploaded to your servers?
Never. Data is streamed in ephemeral memory buffers directly between your devices over an end-to-end encrypted (DTLS 1.3) peer-to-peer data channel. Nothing is ever written to disk on intermediate cloud servers.
How fast is the transfer speed between devices?
When both devices share the same local Wi-Fi network, transfers bypass the public internet and operate at the maximum bandwidth speed of your router, routinely reaching 50MB/s to 120MB/s.
What makes Textunnel different from traditional cloud drives like Google Drive or Dropbox?
Cloud storage requires a two-step process: uploading the full file to a remote server, then downloading it on the second device. Textunnel establishes a direct peer-to-peer connection so data streams simultaneously between devices, saving 50% of your time and eliminating cloud storage quotas.
Can I transfer large video files exceeding 20GB without browser crashes?
Yes. Textunnel utilizes custom chunked streaming and browser backpressure management. Large video files are processed in small memory buffers rather than loaded all at once, preventing out-of-memory tab crashes.
