Feature Comparison
Perkoon
Unlimited Free P2P Transfers
Perkoon's primary feature is its unlimited, free peer-to-peer file transfer. When both sender and recipient are online, files are beamed directly from one browser to another. This method imposes no file size limits, requires no user accounts, and ensures complete privacy as the data never touches Perkoon's servers. The service remains free because this direct streaming costs the company virtually nothing to operate.
Encrypted Cloud Storage for Offline Sending
For situations where the recipient is not immediately available, Perkoon provides encrypted cloud storage. This is a paid feature that honestly covers the cost of running and maintaining secure servers. Files are held securely until the recipient is ready to download them, bridging the gap when real-time P2P transfer isn't possible.
Native AI and Automation Integration
Perkoon is built for the age of automation. It features a native API (window.__perkoon) that allows AI agents and scripts to interact with the service programmatically without the need for inefficient screen-scraping. This enables seamless integration into automated workflows, making file transfer a natural part of machine-driven processes.
Simple CLI and Browser Tool
Beyond the web interface, Perkoon offers a straightforward Command Line Interface (CLI) tool. This provides power users and developers with a fast, scriptable method to transfer files directly from their terminal, complementing the web and automation capabilities for a complete toolset.

An AI assistant tasked with compiling a report can use Perkoon's built-in agent tools to directly upload the final document and generate a shareable link for a human user. This eliminates manual steps and allows AI agents to operate file transfer services autonomously and reliably.
