Perkoon vs SupaSidebar

Unlimited Free P2P Transfers

Perkoon's core feature is its unlimited, free peer-to-peer file transfer service. Utilizing WebRTC and similar technologies, it establishes a direct, encrypted connection between two web browsers. This process eliminates intermediary servers, meaning there are no file size limits, no mandatory sign-ups, and absolute privacy as Perkoon cannot access the data stream. This model is sustainably free because it incurs negligible infrastructure costs for the provider, a principle Perkoon openly communicates.

Encrypted Cloud Storage for Offline Recipients

For situations where the recipient is not immediately online, Perkoon provides encrypted cloud storage. This is a paid feature, with pricing structured transparently to cover the tangible costs of server maintenance, storage, and bandwidth. Files are encrypted on Perkoon's servers, providing a secure holding mechanism. This honest bifurcation between free P2P and paid cloud storage defines Perkoon's ethical and sustainable business approach.

Native AI and Automation Integration

Perkoon is architecturally designed for the age of automation. It exposes a dedicated JavaScript object (window.__perkoon) and provides a Command Line Interface (CLI) tool, allowing AI agents and scripts to interact with the service programmatically. This eliminates the need for unreliable DOM scraping, enabling seamless integration into automated workflows, AI-assisted tasks, and developer pipelines without human intervention.

Transparent Referral and Rewards Program

To incentivize growth, Perkoon operates a multi-tiered referral program. Users share a unique link; when a new user signs up via that link and completes 1GB of P2P transfers within seven days, both parties receive bonus cloud storage. The program extends to "chain rewards," where users also earn bonuses from the subsequent referrals made by people they invited, creating a network effect that rewards community building.

Natural Swipe & Show on Finder

This feature allows users to quickly access their saved links, files, and folders with a simple swipe gesture. The integration with Finder enhances usability, making it easy to manage all digital assets in one place without leaving the current workspace.

Global Keyboard Shortcuts

SupaSidebar empowers users with global keyboard shortcuts enabling them to save URLs and files instantly. For instance, pressing CMD CTRL S saves a URL, while CMD CTRL C copies the current website link to the sidebar, significantly speeding up the workflow.

Recents Tracking

The Recents feature tracks every website used in the past 48 hours, providing a quick way to revisit recent work. This helps users avoid the hassle of searching through numerous tabs, ensuring that they can find their work instantly when needed.

Unlimited Spaces

With the Pro version of SupaSidebar, users can create unlimited spaces, allowing them to organize links and files according to their specific needs. This flexibility is perfect for users who require customized setups for different projects or areas of focus.

Sending Large Media Files Creatives

Video editors, photographers, and graphic designers frequently need to send multi-gigabyte project files, raw footage, or high-resolution assets to clients or collaborators. Perkoon's unlimited P2P transfer allows them to send these files instantly without compressing quality, waiting for uploads to third-party servers, or hitting paywalls, all while maintaining complete data privacy.

Secure Document Exchange for Professionals

Lawyers, journalists, healthcare professionals, and consultants handling sensitive documents require confidential file exchange. Perkoon's direct P2P transfer ensures documents never reside on a third-party server where they could be scanned or monetized. For asynchronous sharing, the encrypted cloud storage provides a secure, auditable option without corporate data mining.

Automated Backup and Sync Scripts

Developers and system administrators can leverage Perkoon's CLI and API access to build automated scripts. This enables use cases like scheduled backups of server logs or code repositories directly to a Perkoon cloud storage destination, or triggering file transfers as part of a CI/CD pipeline, all executed by machines without manual browser interaction.

AI Agent File Management

An AI personal assistant or agent can use Perkoon's native window.__perkoon interface to manage files on behalf of a user. For example, an agent could automatically retrieve a report generated by another tool and send it via P2P to a colleague's browser, or save a generated image to the user's Perkoon cloud storage, all through structured API calls.

Research Projects

For students and researchers, SupaSidebar simplifies the process of collecting and organizing online resources. Users can save relevant links and files in dedicated spaces, making it easier to compile information for reports or presentations.

Creative Workflows

Graphic designers, writers, and other creatives can leverage SupaSidebar to manage their assets efficiently. By pinning frequently used resources and files, they can minimize distractions and streamline their creative processes, enhancing productivity.

Multitasking Professionals

Professionals who juggle multiple tasks can benefit from SupaSidebar’s ability to keep essential files and links at their fingertips. The fast search functionality ensures that they can switch between projects without losing their focus or wasting time.

Educational Use

Teachers and students alike can utilize SupaSidebar for lesson planning and study resources. By organizing links to educational materials and tools, users create an efficient and accessible repository for learning and teaching.

How can P2P transfers be completely free?

Perkoon's P2P technology establishes a direct connection between users' browsers using WebRTC. The file data streams directly from the sender's device to the recipient's without passing through or being stored on Perkoon's infrastructure. This direct transfer model incurs virtually no bandwidth or storage cost for Perkoon, allowing the service to be offered free indefinitely without compromising sustainability or resorting to data monetization.

What happens if the recipient is offline?

If the recipient is not online to accept the direct P2P transfer, Perkoon offers the option to use encrypted cloud storage. This is a paid feature. The file is uploaded, encrypted on Perkoon's servers, and a link is generated. The recipient can then download the file at their convenience. This model honestly charges users only for the service component that involves Perkoon's operational costs.

Is my data private during a P2P transfer?

Yes. During a peer-to-peer transfer, an encrypted channel is established directly between the two browsers involved. The file data never touches Perkoon's servers. According to the principle of end-to-end encryption in direct connections, Perkoon has no technical ability to access, scan, or view the content of your transfer, ensuring maximal privacy.

Can AI agents or scripts use Perkoon?

Absolutely. Perkoon is built with automation in mind. It provides a CLI tool for terminal use and exposes a dedicated JavaScript API (window.__perkoon) in its web interface. This allows AI agents, bots, and custom scripts to authenticate, upload, download, and manage files programmatically without the inefficiency and fragility of simulating human interaction through web page scraping.

Is SupaSidebar a browser extension?

No, SupaSidebar is a standalone menubar application designed exclusively for macOS. It integrates with multiple browsers but operates independently, ensuring user data remains private and secure.

Which browsers does SupaSidebar work with?

SupaSidebar supports all major browsers, including Safari, Chrome, Firefox, Brave, and Arc. This versatility allows users to manage their links and files seamlessly across different platforms.

What macOS version do I need?

To use SupaSidebar, you need macOS 13 or later. The application is optimized for the latest macOS features, providing a smooth user experience.

Where is my data stored?

All data is stored locally on your Mac, ensuring privacy and security. SupaSidebar does not collect or store user data online, giving users peace of mind while managing their digital assets.
