About StreamSnatcher
Lightning‑fast, private, browser‑to‑browser file transfers powered by WebRTC—no accounts, no uploads to cloud storage, just direct, secure connections between peers.
Our Mission
StreamSnatcher exists because sharing a file should be as simple as handing someone a flash drive — except without the flash drive. Traditional file sharing forces you through a roundabout journey: upload your file to a cloud server, wait for it to finish, copy a link, send it to your recipient, then wait again while they download from that same server. Along the way, your data sits on someone else's computer, accessible to the service provider, potentially exposed to breaches, and subject to storage quotas.
We built StreamSnatcher to eliminate that entire middle step. By leveraging WebRTC — the same technology that makes browser-based video calls possible — files travel directly from your browser to the recipient's browser. There is no upload, no cloud storage, and no download link. The transfer is immediate, the architecture is private by default, and the service is free to use without registration.
Our mission is to make peer-to-peer file transfer accessible to everyone: individuals sharing family photos, teams exchanging design assets, professionals transferring sensitive documents, and anyone who values speed and privacy over the convenience theater of cloud-first workflows.
Why StreamSnatcher?
Most file-sharing tools are built around a server-centric model: your file goes up to the cloud, then back down to the recipient. This works, but it introduces latency (you wait for two transfers instead of one), privacy concerns (a third party stores your data), and artificial limits (free tiers cap file sizes at 2 GB, 5 GB, or 25 MB for email attachments).
- Direct peer‑to‑peer transfers — files flow between browsers with no server storage, ever. Your data never sits on someone else's infrastructure.
- Real‑time speed — on a local network, transfers can saturate your connection because there's no cloud middleman adding latency.
- No sign‑in required — create a session and start transferring in under ten seconds. No email verification, no password, no profile.
- Works across modern browsers — Chrome, Firefox, Edge, Safari, Opera, and Brave all support the WebRTC standard that StreamSnatcher is built on.
- No file size limits — send a 50 KB text file or a 50 GB video project. The practical ceiling is your device's memory and storage, not an artificial quota.
- Built‑in encryption — WebRTC data channels use DTLS encryption by default. Your files are protected in transit without any extra configuration.
The Technology Behind StreamSnatcher
StreamSnatcher is built on WebRTC (Web Real-Time Communication), an open-source framework originally developed by Google and now standardized by the W3C and IETF. WebRTC was designed to enable real-time audio and video communication directly between browsers, but its data channel capability is equally powerful for transferring arbitrary binary data — including files of any type and size.
How WebRTC data channels work
When two peers want to exchange files, their browsers perform a handshake process called signaling. During signaling, each browser generates an SDP (Session Description Protocol) offer describing its capabilities, and they exchange ICE (Interactive Connectivity Establishment) candidates — essentially, lists of network addresses the browsers can use to reach each other. StreamSnatcher's server facilitates this signaling exchange, but once the connection is established, the server is no longer involved in the data flow.
The resulting peer connection uses SCTP (Stream Control Transmission Protocol) over DTLS (Datagram Transport Layer Security), which provides both encryption and reliable, ordered delivery of data. Files are split into chunks, sent through this encrypted channel, and reassembled on the receiving end — all within the browser, with no plugins or extensions required.
NAT traversal: STUN and TURN
Most devices sit behind NAT (Network Address Translation) routers, which means they don't have direct public IP addresses. WebRTC uses STUN (Session Traversal Utilities for NAT) servers to help each peer discover its public-facing IP address and port. In most cases, this is sufficient to establish a direct connection.
When both peers are behind symmetric NATs or restrictive firewalls that prevent direct connections, WebRTC falls back to a TURN (Traversal Using Relays around NAT) server, which relays data between peers. While this adds latency, the data remains encrypted end-to-end. StreamSnatcher configures both STUN and TURN servers to maximize connectivity across different network environments.
Open standards, no vendor lock-in
Because WebRTC is an open W3C standard implemented natively in every major browser engine (Blink, Gecko, and WebKit), StreamSnatcher doesn't depend on proprietary plugins, third-party SDKs, or platform-specific runtimes. This means the service works on Windows, macOS, Linux, iOS, and Android — any device with a modern browser can participate in file transfers without installing anything.
Privacy by Design
Privacy isn't a feature we added on top of an existing architecture — it's a consequence of the architecture itself. When files never pass through a centralized server, there's nothing to log, nothing to scan, and nothing to subpoena. Here's how this works in practice:
End‑to‑end encrypted
All transfers use DTLS-encrypted WebRTC data channels. Encryption keys are negotiated directly between peers, so StreamSnatcher — and your ISP — never see the plaintext content.
No server file storage
Files never touch our servers. We don't have the infrastructure to store, inspect, or index your data. The server only facilitates the initial connection handshake.
Minimal technical metadata
We process only the minimum metadata needed for connection establishment: session IDs, ICE candidates, and short-lived diagnostic logs that are discarded after the session ends.
User control
Sessions are entirely ephemeral. Close the browser tab, and the session — along with all associated connection data — ceases to exist. There are no persistent user accounts or activity histories.

Built for Performance
StreamSnatcher isn't just private — it's fast. By cutting out the cloud middleman, transfers happen at the maximum speed your network allows. Here's what powers the performance:
WebRTC data channels
Optimized binary transport using SCTP, which provides reliable, ordered delivery with built-in congestion control — purpose-built for streaming large files efficiently in browsers.
Adaptive chunking
Files are split into variable-size chunks that adapt to network conditions, improving throughput on fast connections and maintaining stability on constrained ones.
Session-based architecture
Room-based sessions with unique codes and QR support make it easy to connect quickly. Sessions are lightweight and designed for minimal overhead.
Cross‑browser compatibility
Works natively in Chrome, Firefox, Edge, Safari, Opera, and Brave — no plugins, extensions, or downloads required on any supported platform.
The interface is designed for clarity and speed: drag‑and‑drop file selection, real-time progress indicators with per-file status, and a minimal number of steps from opening the page to completing a transfer.
Who Uses StreamSnatcher?
Personal sharing
Send vacation photos, home videos, and documents to friends and family without uploading to cloud services. No storage limits, no account required, no link expiration.
Team handoffs
Exchange design files, build artifacts, presentations, and drafts with collaborators in real time. Skip the upload-wait-download cycle of shared drives.
Sensitive transfers
Transfer confidential documents, legal files, or medical records directly between devices for scenarios where data should never reside on third-party servers.

What's Next
StreamSnatcher is under active development. Here's what we're working on and considering for future releases:
- Resumable transfers — recover interrupted transfers without starting over, especially important for large files on unstable connections.
- Enhanced connection diagnostics — self-serve troubleshooting tools that help identify whether issues are network-related, browser-related, or firewall-related.
- Smarter chunk parallelization — leveraging multiple data channels simultaneously to better utilize high-bandwidth connections.
- Session presets — preconfigured modes for common scenarios like one-to-one transfers, broadcast sending, and round-robin distribution.
- Time-boxed share links — optional link-based share flows with automatic expiration windows for added security.
