Feature Comparison
Perkoon
Unlimited Peer-to-Peer (P2P) Transfers
This is the foundational, free-forever feature. Using WebRTC technology, Perkoon establishes a direct, encrypted connection between two browsers for real-time file transfer. Since the data never passes through Perkoon's servers, there are no file size limits, no mandatory sign-ups, and absolute privacy. This model is sustainably free because it incurs negligible infrastructure costs, passing the savings and freedom directly to the user.
Honest Encrypted Cloud Storage
For situations where the recipient is offline, Perkoon offers a paid cloud holding service. Files are encrypted on Perkoon's servers before storage. This feature is transparently priced to cover the actual costs of server maintenance and bandwidth, representing an ethical alternative to services that hide real costs behind data mining and privacy invasions.
Native AI & Automation Integration
Perkoon is architecturally prepared for the future. It exposes a dedicated JavaScript object (window.__perkoon) allowing AI agents and automation scripts to interact with the transfer service programmatically. This eliminates the need for unreliable screen-scraping, enabling machines to send, receive, and manage files as a native utility within automated workflows.
Simple CLI and Browser Tools
Complementing its web interface, Perkoon provides a straightforward Command Line Interface tool. This caters to developers, power users, and automated systems, enabling file transfers to be integrated into scripts, build processes, and backend operations, ensuring flexibility across different user environments and technical proficiencies.

Use Cases
Perkoon
Sending Large Project Files to Clients
Freelancers and agencies can instantly send massive video edits, design prototypes, or code repositories directly to a client's browser without worrying about compression, split archives, or expired download links. The P2P transfer handles unlimited sizes with no account required from the client, streamlining professional delivery.
Asynchronous Collaboration Across Time Zones
When a team member is offline, a user can upload files to Perkoon's encrypted cloud storage. The recipient receives a notification and can securely download the files at their convenience, ensuring work continues smoothly without being constrained by simultaneous online presence or insecure email attachments.
Integrating File Transfer into Automated Workflows
Developers can use the CLI tool or AI API to automatically upload build artifacts, backup logs, or transfer processed data between services. An AI agent can be instructed to fetch a report and send it via Perkoon as part of a scheduled task, making file transfer a reliable, programmable step in a larger process.
Privacy-Conscious Personal Sharing
Individuals sharing sensitive documents, personal photos, or large media collections can use Perkoon's P2P mode for peace of mind.

Frequently Asked Questions
Perkoon FAQ
Is the P2P transfer really free forever?
Yes. The peer-to-peer transfer technology operates directly between user browsers. Since Perkoon does not use its own servers or bandwidth to facilitate the data transfer for P2P, the operational cost is effectively zero. Therefore, this service can be offered without charge indefinitely, with no hidden catches or data monetization.
What happens if the recipient is not online when I send a file?
If the recipient is offline, the P2P connection cannot be established. In this case, you can use Perkoon's encrypted cloud storage feature (a paid option) to upload the file. The file is held securely on Perkoon's servers until the recipient comes online and accesses their unique download link.
How does Perkoon ensure my privacy?
For P2P transfers, privacy is inherent; files stream directly between devices and are never stored on or accessible to Perkoon's servers. For cloud storage, files are encrypted on your device before being uploaded. Perkoon maintains a strict policy of no scanning, no selling of data, and no "corporate nonsense" regarding user files.
Can AI agents or scripts really use Perkoon without a browser?
Yes. Perkoon is built for automation. It provides a dedicated JavaScript API (window.__perkoon) on its web interface for AI agents to interact with programmatically. Additionally, a Command Line Interface (CLI) tool is available, allowing scripts and backend systems to initiate and manage file transfers directly, enabling full integration into automated pipelines.
