Feature Comparison
Perkoon
Peer-to-Peer (P2P) File Transfer
Perkoon's flagship feature allows users to send files directly between browsers without any size limitations or sign-ups. This P2P technology ensures that files are transmitted securely and privately, as they do not pass through any central servers. This direct connection makes file sharing efficient and stress-free.
Encrypted Cloud Storage
For instances when recipients are offline, Perkoon provides an encrypted cloud storage solution. This paid feature securely holds files until the recipient is available to download them. The encryption ensures that users' data remains private and protected during transit and storage.
Built-in Automation Tools
Perkoon is designed with the modern user in mind, incorporating built-in tools that allow for automation and integration with AI agents. These features streamline the file transfer process, enabling users to interact with the service directly without the need for cumbersome screen-scraping methods.
Referral and Rewards Program
Perkoon offers a unique referral program that rewards users for sharing the service with others. By sending a referral link, users can earn extra storage space when their friends sign up and transfer files. This incentivizes community growth while benefiting all participants.
SupaSidebar
Universal Capture with Keyboard Shortcuts
SupaSidebar empowers you to save content without interrupting your flow. Using intuitive global keyboard shortcuts, you can instantly capture the current website link (CMD+CTRL+S) or copy it to your clipboard (CMD+CTRL+C) directly from any browser. This eliminates the tedious process of manually copying, switching apps, and pasting, making saving references, articles, or tools a seamless part of your browsing experience.
Recents History for Instant Recall
Never lose track of your digital trail. SupaSidebar automatically tracks every website you visit across all supported browsers for the past 48 hours, logging them in the "Recents" section. This feature acts as a short-term memory for your Mac, allowing you to instantly find and re-open that webpage you were viewing just a short while ago without digging through your browser history or countless open tabs.
Fast Universal Search
Access anything on your Mac with a single keystroke. By pressing CMD+CTRL+K, you activate a powerful search bar that scans across all your saved items—websites, files, folders, and applications. This centralized search function means you can launch apps, open documents, or navigate to saved links without ever taking your hands off the keyboard, dramatically speeding up task switching.
Organized Spaces and Pinned Favorites
Keep your most critical resources immediately accessible. You can pin important links, files, or folders to the top of your sidebar for one-click access. Furthermore, SupaSidebar organizes items into separate "Spaces," allowing you to categorize resources by project, topic, or context. This structure helps maintain order and ensures you can quickly find what you need for your current task.
