GPHost — Smart Ephemeral File Transit & Direct Cloud Sharing
Fast, simple file sharing and direct-to-cloud transit up to 1 GB with zero wait times, secret password locks, auto-expiring links, and live visitor stats.
How It Works & Why It Matters
GPHost is a modern web application designed to make sharing files as quick, simple, and safe as possible. Most traditional file transfer sites make your files wait in long server lines, which slows down transfers and can compromise privacy. GPHost solves this by letting your web browser upload directly to high-speed Cloudflare R2 cloud storage. You can send large files up to 1 GB in seconds, protect them with secret passwords, set them to self-destruct after one download, and get clean direct links to display photos or play videos on blogs and websites without annoying ads or wrapper pages.
Direct Browser-to-Cloud Transit (No Slow Middleman)
Engineered with a direct-to-storage design: your web browser sends files straight to Cloudflare R2 storage using secure temporary upload leases, completely avoiding slow web servers.
- Lightning-Fast Uploads: Files stream directly from your device to Cloudflare R2 without going through intermediary servers, giving you maximum upload speed.
- Smart Piece-by-Piece Uploading: Big files up to 1 GB are split into small 5 MB pieces and uploaded in parallel, with automatic retries if your internet hiccups.
- Secret In-Browser Encryption: Before any sensitive file leaves your computer, your browser can lock it with bank-grade AES-256 encryption. The secret key stays in the URL link and is never sent to our servers.
- Automatic Self-Destruction: Supports 'Burn-on-Open' (destroys the file 60 seconds after first viewing) and single-use links that delete the file as soon as it is downloaded once.
- Real-Time Visitor Insights: See live download counts and an interactive world map showing which countries your visitors came from, without any tracking cookies.
Technical Challenges & Practical Solutions
Uploading large 1 GB files smoothly without freezing the browser or dropping out
Built a smart upload manager that slices large files into 5 MB chunks, handles parallel uploads, and verifies every chunk with a SHA-256 checksum so you never lose progress.
Keeping confidential files 100% private without having to trust server administrators
Implemented native browser-based Web Crypto AES-256 encryption. The encryption key is stored only in the URL hash fragment (#key=...), which web browsers never transmit across the internet to the server.
Preventing old, forgotten files from lingering forever and wasting cloud storage space
Created automated self-destruct timers and database cleanups. The instant a countdown timer hits zero or a single-use download finishes, the file is permanently deleted from cloud storage.
Core Capabilities
