About Textunnel — Zero-Install P2P Productivity
Open-source, zero-install cross-device productivity. Built for software developers, filmmakers, remote teams, and privacy-conscious users who demand fast, encrypted peer-to-peer file transfers and real-time clipboard synchronization without installing software.
Up to 120 MB/s Local Wire Speed
Transfers stream directly across your local Wi-Fi 6 router or mobile hotspot via WebRTC DataChannels, bypassing asymmetric cloud upload limits.
100% Zero-Cloud Storage
Files stream chunk-by-chunk directly into recipient device memory. Zero bytes are ever written, saved, or cached on remote hard drives.
50GB+ Large File Engine
Engineered with custom backpressure flow control and the Screen Wake Lock API to prevent memory overflows and sleep dropouts during overnight transfers.
Open Source & Free Forever
Built on a 100% client-side serverless architecture. Zero expensive database hosting overhead guarantees Textunnel remains completely free.
Our Core Mission: Frictionless Productivity
Transferring a 5GB 4K video or copying an authentication OTP token between your iPhone and Windows laptop should not require installing heavy companion apps, plugging in fragile USB cables, or creating third-party cloud accounts.
We created Textunnel to eliminate the arbitrary barriers imposed by closed corporate ecosystems. By harnessing standard web technologies already present in Google Chrome, Apple Safari, Microsoft Edge, and Mozilla Firefox, we provide an immediate, hardware-agnostic bridge between iOS, Android, macOS, Windows, and Linux.
Privacy by Architecture, Not Just Policy
Traditional file-sharing platforms store your confidential data on remote servers, exposing it to potential data leaks, unauthorized scraping, and mandatory retention periods. Textunnel rejects this centralized paradigm entirely:
- Ephemeral Memory Only: Transferred files and clipboard strings exist strictly in active RAM buffers while both browser tabs remain open.
- DTLS 1.3 End-to-End Cryptography: All data packets are encrypted using modern cryptographic standards before leaving your device.
- No User Profiling: We require zero logins, zero phone numbers, and zero tracking cookies to use any feature in our tool suite.
Engineering Principles & Web Standards
Our engineering philosophy prioritizes performance, open web standards, and radical simplicity:
WebRTC DataChannels
Enables high-throughput bidirectional binary streaming with minimal protocol latency.
HTML5 File System & Streams
Streams multi-gigabyte datasets in small memory slices without exhausting browser heap limits.
Open Source Transparency & GitHub Community
We believe that software dealing with personal files and clipboard data must be open to independent verification. Textunnel is publicly open-sourced on GitHub. Anyone can inspect our code, verify our WebRTC signaling implementation, or contribute to upcoming features.
Frequently Asked Questions About Textunnel
What is Textunnel and how does it work?
Textunnel is an open-source, browser-native productivity suite that enables instant peer-to-peer file sharing and real-time clipboard synchronization. Using WebRTC DataChannels, files and text stream directly across local Wi-Fi or cellular networks without intermediate cloud servers.
Is Textunnel really 100% free with no hidden paywalls?
Yes. Because Textunnel uses a peer-to-peer architecture, your devices transfer data directly without burdening expensive central storage servers. This structural efficiency allows us to keep Textunnel completely free and open-source.
How does Textunnel protect my privacy and data security?
Textunnel utilizes DTLS 1.3 encryption and ephemeral in-memory processing. Your files and clipboard snippets never write to disk on third-party servers. The moment you close the browser tab, all session cryptographic keys and memory buffers are immediately destroyed.
Which operating systems and browsers are supported?
Textunnel runs in all modern web browsers supporting WebRTC, including Chrome, Safari, Microsoft Edge, Mozilla Firefox, and Brave across Windows, macOS, iOS, Android, and Linux.
Can I transfer large video files without browser tab crashes?
Yes. Textunnel features an advanced chunked streaming engine with browser backpressure control and HTML5 Screen Wake Lock integration, allowing seamless multi-gigabyte transfers up to 50GB+.
How can I contribute to Textunnel development?
Textunnel is publicly open-sourced on GitHub. Developers can submit issues, propose pull requests, and contribute to WebRTC optimizations at https://github.com/haihiaen/Textunnel.
