Feature Comparison

Perkoon

Unlimited Free P2P Transfer

This is the core of Perkoon. When both sender and recipient are online, files stream directly from one browser to another using peer-to-peer technology. This means there are absolutely no file size limits, no mandatory sign-ups, and because the data bypasses central servers entirely, it's private by design and costs Perkoon nothing to operate. It's free for you, forever, with no hidden catches.

Encrypted Cloud Storage for Offline Sends

Need to send a file to someone who isn't online right now? Perkoon's cloud storage feature has you covered. Files are securely encrypted on Perkoon's servers and held until the recipient is ready to download. This is the service's paid feature, and the pricing is transparently structured to honestly cover the cost of running and maintaining this infrastructure—no profit markup on privacy.

Native AI & Automation Integration

Perkoon is built for the age of automation. Instead of forcing AI agents to awkwardly scrape web pages, Perkoon provides a native JavaScript object (window.__perkoon) and a Command Line Interface (CLI) tool. This allows scripts, bots, and AI assistants to interact with the file transfer service directly and programmatically, enabling seamless automated workflows without friction.

Transparent Referral & Rewards Program

Perkoon incentivizes growth in a mutually beneficial way. Share your unique referral link; when someone signs up through it, you both get a bonus boost of cloud storage. When they complete 1GB of P2P transfers, you both earn even more. The program includes chain rewards, meaning you can earn bonuses from your referrals' referrals, building a network that continuously rewards active users.

SupaSidebar

Universal Browser Integration

SupaSidebar works flawlessly with every major browser you use, including Safari, Chrome, Firefox, Brave, and Arc. This universal compatibility means you can save the current webpage link directly to your sidebar from any browser instantly. No more switching contexts or manually copying and pasting URLs between applications. It creates a unified hub that sits above your browser choice, ensuring your workflow remains consistent and uninterrupted regardless of which window you're in.

Lightning-Fast Global Keyboard Shortcuts

Take control with powerful, system-wide keyboard shortcuts that work anywhere on your Mac. Press CMD+CTRL+S to instantly save the current website link directly to your sidebar. Use CMD+CTRL+K to open a blazing-fast search overlay to find any saved link, file, folder, or application. These shortcuts are designed for muscle memory, letting you access your entire digital workspace without ever touching your mouse, dramatically speeding up your navigation and task execution.

Intelligent Recents & Pinned Favorites

Never lose your work again. SupaSidebar's "Recents" feature automatically tracks every website you've visited in the last 48 hours, giving you a chronological lifeline back to your research or browsing session. For your core resources, use the "Pinned" section to keep essential links, files, and folders permanently anchored at the top of your sidebar for one-click access. This combination of automatic history and manual curation ensures both serendipitous rediscovery and reliable, instant access to your most critical items.

Native macOS Design & Local Data Storage

SupaSidebar is built from the ground up for the Mac experience, ensuring buttery-smooth performance and seamless integration with macOS aesthetics and behaviors. Critically, all your data—every saved link, file reference, and folder path—is stored locally on your machine. Nothing is sent to the cloud unless you choose to, guaranteeing your privacy and security. This lightweight, menubar-based approach keeps your desktop clean and clutter-free while providing powerful organization.

Use Cases

Perkoon

Sending Large Project Files to Clients

Freelancers, designers, and videographers can instantly send massive project files—think 50GB video edits or design suites—directly to a client's browser. No compressing, splitting, or begging clients to sign up for a service. It's a frictionless, professional transfer that respects both parties' time and data.

Automated Backup & Data Pipeline Scripts

Developers and sysadmins can integrate Perkoon's CLI into their scripts. Automate the transfer of log files, database dumps, or backup archives from a server to a designated recipient or storage node. The native API access means reliable, programmatic file movement without building custom infrastructure.

Privacy-Conscious Document Sharing

Lawyers, journalists, or anyone handling sensitive information can share documents with the assurance of true P2P privacy. Since files in a direct transfer never pass through a third-party server, there's zero risk of corporate scanning, data mining, or unauthorized access by the service provider itself.

AI Agent File Management

An AI assistant managing your workflow can use Perkoon's built-in window.__perkoon object to send you generated reports, receive documents for processing, or distribute outputs to a team. This turns Perkoon into a seamless file highway for autonomous agents, supercharging productivity without manual intervention.

SupaSidebar

The Deep Work Researcher

When conducting online research, you often have dozens of tabs open across multiple articles, papers, and sources. SupaSidebar cuts through the chaos. Save every relevant source to your sidebar with a single shortcut as you browse. Later, use the powerful search or Recents list to instantly jump back to any source without sifting through a mountain of tabs. Keep key reference materials pinned for constant access, turning a fragmented research session into a streamlined, organized process.

The Multitasking Project Manager

Juggling multiple projects means constantly switching between communication apps, project docs, design files, and tracking tools. SupaSidebar acts as your central command panel. Pin the Trello board, Google Doc, Figma file, and Slack channel for each active project into dedicated spaces. With a quick CMD+CTRL+K, type the project name and jump directly to the required resource in seconds. It eliminates app-switching friction and keeps all project assets at your fingertips.

The Creative Professional

Creatives juggle inspiration links, asset folders, brand guidelines, and creative software. SupaSidebar streamines this creative toolkit. Save mood board URLs, pin your local folder of stock assets, and keep your go-to design apps handy. When moving from brainstorming in a browser to executing in a design app, everything you need is in one consistent sidebar, preventing disruptive searches through Finder or bookmarks and helping you maintain your creative flow.

The Developer & Technical Power User

Developers context-switch between API documentation, GitHub repositories, local project folders, and terminal sessions constantly. SupaSidebar supercharges this workflow. Pin your most-visited docs, save crucial Stack Overflow answers, and have quick links to your active project directories. Use global shortcuts to log references without leaving your code editor. It reduces context-switching overhead, keeping your development environment tight and efficient.

Frequently Asked Questions

Perkoon FAQ

Is the P2P transfer really free forever?

Yes, absolutely. The peer-to-peer transfer technology sends files directly between browsers. This process costs Perkoon essentially nothing in server bandwidth or storage overhead. Therefore, they can offer it as a free service indefinitely, with no file size limits. The business model is sustained by the optional paid cloud storage feature.

What happens if the recipient is offline?

If the recipient is not online to receive a direct P2P transfer, Perkoon will seamlessly offer to use its encrypted cloud storage instead. 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, with the link expiring after a set period.

Can Perkoon see what I'm sending in a P2P transfer?

No. In a direct P2P transfer, the file data streams exclusively between the two users' browsers using WebRTC technology. Perkoon's servers only facilitate the initial connection ("signaling") but never handle the actual file data. They are technically incapable of seeing, scanning, or storing the content of your transfer.

Which browsers are supported?

For the full, unlimited P2P experience, Chromium-based browsers like Chrome, Edge, and Brave work perfectly. Firefox and Safari have inherent browser restrictions that can limit transfer speeds or maximum file sizes for P2P connections. All major browsers support the cloud storage send and download functionality.

SupaSidebar FAQ

Is SupaSidebar a browser extension?

No, SupaSidebar is not a browser extension. It is a standalone, native macOS application that runs from your menubar. It integrates with your browsers at a system level to read the current tab's URL, but it operates independently. This means it works uniformly across Safari, Chrome, Firefox, Brave, and Arc without requiring individual extension installation or management.

Which browsers does SupaSidebar work with?

SupaSidebar offers seamless integration with all major browsers on macOS. This includes Safari, Google Chrome, Mozilla Firefox, Brave, and the Arc browser. The application is designed to detect and work with the currently active tab in any of these supported browsers, allowing you to save links and interact with your web content consistently from a single, unified sidebar.

Where is my data stored?

All your data is stored locally and privately on your Mac. Your saved links, file paths, and organizational structure (like pins and spaces) are kept on your own machine. SupaSidebar does not upload your personal browsing data or saved items to any external cloud servers by default, ensuring your privacy and security are maintained.

What macOS version do I need?

SupaSidebar requires macOS 13 (Ventura) or a newer version to operate. This ensures the application can utilize the latest macOS frameworks and technologies to deliver a stable, performant, and deeply integrated experience that aligns with modern Apple system design and security standards.
