Credits are purchased once and never expire. Domain: https://filefly-two.vercel.app/upload Market Opportunity FileFly is a file-transfer utility in the same category as WeTransfer, Smash, and Send Anywhere, built specifically for users who need to send a file without creating an account. The concept is intentionally simple: Pick a File → Upload → Get a Share Link → Send It. Free transfers support files up to 10 MB with links that remain available for seven days. Larger transfers — up to 5 GB — are unlocked using prepaid credits. Unlike many file-transfer services that push users toward registration, subscriptions, or recurring plans, FileFly is built around a one-off use case. No Sign-Up. No Email. No Password. No Profile. The device generates an anonymous identity on first use, allowing users to start transferring files immediately. Why FileFly? Most people don't need a permanent file-transfer account. They simply need to send a large file once — to a client, friend, colleague, family member, or another device. FileFly removes the biggest friction point from this process: account creation. Users can open the app, select their file, upload it, and immediately receive a shareable link. The prepaid credit model also matches the behavior of occasional file-transfer users. Instead of paying a recurring subscription for a service they may only use a few times per year, users can purchase credits when they actually need a larger transfer.

The iOS application is built using React Native. The backend and API serve both the mobile and web clients, creating a shared infrastructure that can also support future platforms. Three architectural decisions are particularly relevant for a technical buyer: Direct-to-Storage Uploads – Uploads bypass the API entirely. The client requests a short-lived signed URL and writes directly to object storage. File bytes never transit the application server, helping keep compute costs flat regardless of transfer volume and avoiding a common scaling bottleneck for file-transfer products. Real File Expiration – When a share link expires, the associated object is deleted rather than simply hidden behind a database flag. Share codes are never recycled, meaning an expired link cannot later resolve to another user's file. Secure Link Passwords – Link passwords are stored as salted scrypt hashes rather than recoverable plaintext values. This provides the appropriate security posture for a product that intentionally has no account-recovery system. File Sharing Experience The entire product is designed around a minimal workflow: 1. Select a File Choose a file from the device. 2. Upload FileFly securely uploads the file using the appropriate transfer flow. 3. Create a Link The system generates a unique shareable link. 4. Share Send the link to the recipient through the user's preferred
