Perkoon

Perkoon is a file transfer service that moves files directly between browsers via P2P with no size limit, no account, and no server middleman, while offering encrypted cloud storage for offline recipients and native automation APIs for AI agents.

What is Perkoon?

Perkoon sends files from a browser or CLI to another browser or CLI without uploading to a server. It accepts any file type via drag-and-drop or command line and outputs the file to the recipient's browser or terminal. The web app runs on Chrome, Edge, and Brave with full support; Firefox and Safari have browser restrictions. Perkoon is built by the Perkoon team.

Key Features

• Unlimited free P2P transfers – Files stream directly browser-to-browser using WebRTC. No server touches the data, no size limit, no account required. Both parties must be online.
• Cloud storage for offline recipients – If the recipient is offline, files are encrypted and held on Perkoon’s servers until they arrive. This is a paid feature; see pricing.
• Browser-to-CLI and CLI-to-CLI – Use npx perkoon send/receive from any terminal. Works browser-to-terminal or terminal-to-terminal without a web interface.
• Native agent accessibility – The page exposes window.__perkoon for AI workflows. Agents can send and receive files without scraping the DOM. Automation documentation.
• No tracking, no scanning – Perkoon does not scan, sell, or analyze your files. Essential cookies only, no third-party analytics. Privacy policy.
• Referral program with chain rewards – Share your unique referral link from the dashboard. When a referral signs up and transfers 1GB in 7 days, both earn bonus cloud storage. Invites from your referrals also earn you rewards. See affiliate details.

Who is it for?

• Large-file senders – Individuals who want to send multi-gigabyte files (e.g., 50GB video edits) without signing up or hitting size caps. Just open Perkoon, share the session code, and the file streams directly.
• Teams with offline recipients – Workgroups that need to deliver files to people who can’t receive them immediately. Cloud storage holds encrypted files until the recipient logs in.
• Developers and AI agents – Engineers who need programmatic file transfer. Use the window.__perkoon API or CLI to integrate file sending into scripts, bots, or AI workflows without browser automation.

Use cases

• Send a 50GB project file to a colleague – Open Perkoon, drag the file, share the session code. The file streams directly to their browser. No upload wait, no account, no cost.
• Automate file delivery for AI workflows – A script calls window.__perkoon to send generated reports to a human reviewer’s browser without human intervention.
• Transfer files from terminal to browser – Run npx perkoon send largefile.bin on a server; the recipient opens the Perkoon session in their browser to download. No need for SSH or cloud storage.

How does it work?

Two modes: P2P (both parties online) – the sender’s browser connects directly to the receiver’s browser via WebRTC. Files never reach a server. Cloud (recipient offline) – the file is encrypted and stored on Perkoon’s servers; the recipient can download it later. The referral program offers bonus cloud storage for inviting others.

Pricing

Freemium model. Peer-to-peer transfers are free forever – Perkoon states “P2P stays free because it costs us nothing.” Cloud storage for offline delivery is paid; exact pricing is not listed on this page but is available at pricing. A referral program provides bonus cloud storage for users who invite others.
