— Written by Brendan, Founder of FileShot.io
Quick Comparison
| Feature | LUFI | FileShot |
|---|---|---|
| Deployment | Self-hosted (requires server setup) | Hosted service (no setup) |
| Free Plan | Yes (if self-hosted or on public instance) | Yes (unlimited) |
| Setup Complexity | Requires technical setup (server, database, dependencies) | No setup (browser-based) |
| Zero-Knowledge Encryption | Yes | Yes |
| Encryption | Client-side (LUFI uses AES) | Client-side (AES-256-GCM) |
| File Size Limit | Configurable (instance-dependent) | Unlimited (free tier) |
| Desktop App | No | Yes (Windows, macOS, Linux) |
| Built-in Tools | None | PDF editor, converter, compressor, virus scanner, etc. |
Self-Hosted vs Hosted Service
LUFI (Let's Upload Files Instantly) is an open-source self-hosted file sharing platform with client-side encryption. You run it on your own server (requires technical setup: Perl, database, nginx/Apache config) or use a public instance (with limits). Client-side encryption means a good privacy model, but you're responsible for uptime, security patches, and backups.
FileShot is a hosted zero-knowledge service. No setupâ€â€works in browser immediately. Files are encrypted with AES-256-GCM before upload, and keys live only in the URL fragment. Desktop app available for drag-and-drop. Built-in tools include PDF editor, converter, compressor, and virus scanner. Free tier: 10 GB per file, 50 GB total. Unlimited storage on paid plans.
Setup and Technical Requirements
LUFI requires you to provision a server, install Perl dependencies, configure a database (typically SQLite or PostgreSQL), set up a web server (nginx or Apache), and maintain the installation. Security patches, backups, SSL certificates, and uptime monitoring are your responsibility. If you use a public LUFI instance, you're trusting someone else's server with similar tradeoffs to any hosted service, but with fewer features and typically lower limits.
FileShot requires zero technical setup. Open the website, drag a file, get a link. The service handles infrastructure, security updates, CDN distribution, SSL, and availability. You get the privacy benefits of zero-knowledge encryption without the operational burden of running your own server.
Privacy and Encryption Model
Both LUFI and FileShot use client-side encryption, which means files are encrypted in your browser before upload. The server stores only encrypted data. Decryption keys are never sent to the serverâ€â€they remain in the URL fragment. This zero-knowledge architecture ensures that even the service provider cannot decrypt your files.
LUFI uses AES encryption. FileShot uses AES-256-GCM, a modern authenticated encryption standard that provides both confidentiality and integrity verification. Both approaches deliver strong privacy, but FileShot's implementation is backed by a professional service with dedicated security audits and infrastructure hardening.
Use Cases and Audience
LUFI is for organizations needing full control over infrastructure, compliance requirements for self-hosting, or technical teams comfortable running their own services. If you have strict data residency requirements (files must stay on your own servers), LUFI is a valid option. However, you must handle all operational complexity yourself.
FileShot is for individuals, freelancers, and teams who want zero-knowledge encryption without server management. If you need to share a confidential document, send a large file to a client, collaborate on a design project, or transfer data securely, FileShot delivers that experience instantly with no setup. The built-in tools (PDF editing, file conversion, compression, virus scanning) make it a complete file workflow solution, not just a transfer service.
Cost and Scalability
LUFI is "free" if you self-host, but you pay in server costs (VPS fees, bandwidth, storage), time (setup, maintenance, troubleshooting), and expertise required. A minimal LUFI deployment might cost $5-20/month in hosting, but factoring in your time and technical overhead, the real cost is significantly higher. Public LUFI instances are free but typically have strict file size and retention limits.
FileShot has a fully functional free tier with generous limits (10 GB per file, 50 GB total) and unlimited storage on paid plans. No file size caps. No retention limits unless you want them. Lite ($2/month) removes ads and adds unlimited expiry control. Pro ($5/month) includes 100 GB per file limits and advanced features. Creator ($12/month) has no limits. You pay for convenience and features, not infrastructure management.
Who Should Choose FileShot?
If you want zero-knowledge encryption without running your own server, FileShot is the clear choice. If you value built-in tools (PDF editor, file converter, compressor, virus scanner) integrated into the workflow, FileShot delivers that. If you need generous free storage (50 GB total, 10 GB per file) and file size without worrying about server maintenance, backups, or uptime monitoring, FileShot removes all that complexity.
