Perkoon

Perkoon is a refreshingly honest file transfer service that cuts through the noise and gets back to basics: moving your files from point A to point B without hassle. It's built for anyone tired of artificial limits, mandatory sign-ups, and services that treat your data as a product. At its core, Perkoon offers two smart ways to send files. First, its flagship free service uses peer-to-peer (P2P) technology to beam files directly between browsers when both people are online. This means no size limits, no accounts, and because the data never passes through a central server, it's private and costs Perkoon nothing to run—so it's free for you, forever. For when the recipient is offline, Perkoon provides encrypted cloud storage, a paid feature that honestly covers the cost of running servers. What truly sets Perkoon apart is its native design for the age of AI, offering built-in tools for automation and AI agents to interact with the service directly, no screen-scraping required. With a simple CLI tool also available, Perkoon is the straightforward, powerful, and privacy-focused file transfer solution for real people and the machines that help them.

Truly Free P2P Transfers

This is the heart of Perkoon. When both sender and receiver are online, files travel directly between their web browsers using WebRTC technology. There is no intermediary server, which means there are absolutely no file size caps, no forced account creation, and your data is never stored by Perkoon. It's fast, private, and free because the architecture makes it cost-effective to offer.

Encrypted Cloud Storage for Offline Recipients

Life doesn't always sync up. When you need to send a file to someone who isn't currently online, Perkoon's cloud storage steps in. Your file is encrypted and securely held on a server until your recipient is ready to download it. This is the part of the service that has real infrastructure costs, which is why it operates on a paid model, keeping the business transparent and sustainable.

Native AI & Automation Accessibility

Perkoon is built for the future. It features a machine-readable state, stable DOM selectors, and a dedicated automation API (window.__perkoon). This allows AI assistants, bots, and automated workflows to send and receive files programmatically without the inefficiency and fragility of simulating human clicks. It’s file transfer designed for both people and their digital agents.

Command Line Interface (CLI) Tool

For developers and terminal enthusiasts, Perkoon offers a full-featured CLI accessible via npx perkoon. You can send and receive files directly from your command line, enabling seamless browser-to-CLI and CLI-to-CLI transfers. It brings the same simplicity and power of the web service to your workflow, proving that terminals deserve nice things, too.

Sending Large Project Files to a Client

Freelancers and creatives often need to send massive video edits, design portfolios, or code repositories that exceed the limits of email or other free services. With Perkoon's P2P transfer, you can send hundreds of gigabytes directly to your client's browser in one go, for free, with no compression or wait times, ensuring they get the full-quality work.

Automated Backup Scripts and AI Workflows

A developer has a script that generates nightly reports or an AI agent that creates weekly content batches. Using Perkoon's API or CLI, these automated processes can instantly send the generated files to a designated recipient or cloud folder without any manual intervention, seamlessly integrating file transfer into automated pipelines.

Sharing Personal Media Collections

Imagine wanting to share all your vacation photos and videos from a recent trip with family—a collection easily reaching 50GB. Instead of splitting into dozens of links or paying for a one-time transfer, you can create a single Perkoon P2P link. As long as your family is online, they can download the entire collection directly from you, quickly and privately.

Ad-Hoc Collaboration Between Teams

Two remote team members need to exchange a large dataset or a prototype asset immediately during a call. Instead of uploading to a slow cloud drive, one can start a Perkoon P2P transfer and share the link in the chat. The other person clicks and the file downloads in real-time, facilitating instant, frictionless collaboration without leaving the browser.

Is peer-to-peer (P2P) transfer really free forever?

Yes, absolutely. Perkoon's P2P transfer is free and unlimited because of how it works: files stream directly from one browser to another without ever touching Perkoon's servers. This means there are no storage or bandwidth costs for the company to cover for this specific service, so they can genuinely offer it for free indefinitely, no strings attached.

What happens if the person I'm sending to is offline?

If your recipient is not online to accept the direct P2P connection, Perkoon offers a seamless fallback to encrypted cloud storage. You can choose this option to upload your file to Perkoon's servers, where it is encrypted and held until your recipient comes online to download it. This cloud storage service is a paid feature, as it involves real infrastructure costs.

How does Perkoon protect my privacy?

Privacy is a core principle. In P2P mode, your files never pass through Perkoon's servers; they take a direct path between you and the recipient, so Perkoon cannot see your data. For cloud transfers, files are encrypted on their servers. Perkoon has a strict no-scanning, no-selling data policy, ensuring your files stay yours.

Can I use Perkoon from the command line?

Definitely! Perkoon provides an official Node.js CLI tool. You can install and run it directly with npx perkoon send [file] or npx perkoon receive. This allows you to initiate transfers from your terminal to a web browser, or even between two terminals, making it perfect for scripting and server environments.
