Feature Comparison

Perkoon

Truly Free Peer-to-Peer (P2P) Transfers

This is the core of Perkoon. When both you and your recipient are online, files are beamed directly from your browser to theirs. The data never passes through Perkoon's servers, which means there are absolutely no file size limits, no mandatory accounts, and complete privacy. Because this method costs Perkoon essentially nothing to run, it's completely free for you to use, forever. It's file sharing in its purest, most efficient form.

Honest Encrypted Cloud Storage

For when your friend or colleague is offline, Perkoon offers a paid cloud storage option. This feature is built on transparency: your files are encrypted on their servers, and you pay a fair price that directly covers the cost of providing that storage and bandwidth. There's no hidden agenda or data monetization. It's a straightforward solution for asynchronous file sharing without compromising on security.

Native AI & Automation Ready

Perkoon is built for the future. Instead of forcing AI assistants to awkwardly scrape a website, Perkoon provides a direct way for them to interact with the service through window.__perkoon. This means your AI agents can upload, download, and manage transfers programmatically and efficiently, opening up powerful possibilities for workflow automation without the typical technical headaches.

Simple CLI and Browser Tools

Accessibility is key. Alongside its user-friendly web interface, Perkoon offers a simple Command Line Interface (CLI) tool. This allows tech-savvy users, developers, or automated scripts to integrate file transfers directly into their workflows, from servers to local machines, making Perkoon a versatile tool for both casual and power users.

SupaSidebar

Instant Saving and Copying

With SupaSidebar, saving links and files is a breeze. Use the global keyboard shortcuts CMD + CTRL + S to save items and CMD + CTRL + C to copy the current website link directly to your sidebar. This feature eliminates the tedious steps of manually saving or copying URLs, allowing you to focus on your tasks.

Recents Tracking

Never lose track of your browsing history again with the Recents feature. SupaSidebar automatically tracks every website you have visited in the last 48 hours, making it easy to find your work quickly. This is particularly useful for those who switch between multiple projects or need to revisit recent research.

Pinned Items for Quick Access

SupaSidebar allows you to pin your favorite links, files, and folders at the top of your sidebar. This feature ensures that your most-used items are always front and center, so you can access them with just a click, reducing time wasted searching for frequently used resources.

Switching between apps can slow down your productivity, but not with SupaSidebar. Just press CMD + CTRL + K and start typing to find any file, folder, website, or app instantly. This feature provides a powerful, efficient way to navigate your digital workspace without the hassle of digging through numerous tabs or folders.

Use Cases

Perkoon

Sending Large Project Files to a Client

Need to send a massive video edit, design portfolio, or dataset that's over 50GB? With Perkoon's P2P transfer, you can send it instantly and for free. Just generate a link, share it with your client while you're both online, and the file transfers directly to them without any size restrictions or upload waits to a third-party server.

Sharing Personal Photos and Videos Privately

Tired of services compressing your memories or snooping on your content? Use Perkoon's P2P transfer to share original-quality photos and videos from your holiday or family event directly with loved ones. Since the files go browser-to-browser, they remain completely private between you and the recipient.

Automating Backup Scripts with CLI

As a developer, you can use Perkoon's CLI tool to automate file backups. Write a simple script that uses the CLI to upload crucial logs, database dumps, or project archives directly to your Perkoon cloud storage at regular intervals, creating an efficient, automated off-site backup solution.

Enabling AI Agents to Handle File Tasks

Imagine an AI research assistant that can automatically fetch datasets or save its generated reports. By leveraging Perkoon's native AI integration, you can configure your agent to use the service directly. It can upload collected data or download necessary files without you manually intervening, streamlining complex research or content creation workflows.

Frequently Asked Questions

Perkoon FAQ

Is the P2P transfer really free forever?

Yes, absolutely. Perkoon's peer-to-peer transfer is free forever because of how it works. The files are sent directly from your device to the recipient's device without ever being stored on or passing through Perkoon's servers. This means it costs Perkoon virtually nothing in bandwidth or storage, so they can offer it completely free, with no hidden limits or future fees.

What happens if the other person is offline?

If the recipient is not online to receive the direct P2P transfer, Perkoon offers a solution: encrypted cloud storage. This is a paid feature. You can upload the file to Perkoon's secure servers, and they will hold it for your recipient. When the recipient comes online, they can download it from this temporary cloud storage. You only pay for this cloud storage feature.

Can Perkoon see what I'm sending with P2P?

No, they cannot. During a P2P transfer, your file is broken into encrypted chunks and streamed directly between your browser and the recipient's browser using a secure WebRTC connection. Perkoon's servers only help set up this direct connection (a process called signaling) but never handle the actual file data. They literally have no way to see your files.

Can I use Perkoon with any web browser?

For the best, unlimited experience, Perkoon recommends using Chromium-based browsers like Chrome, Edge, or Brave. These browsers fully support the required technologies. Firefox and Safari can be used, but they have inherent browser restrictions that may limit performance or file size for P2P transfers. It's always best to check the official site for the most current browser compatibility information.
