Perkoon vs Session Stacker

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.

AI-Powered Task Review

Session Stacker leverages advanced AI technology to review your tasks intelligently. This feature analyzes your past sessions and helps you prioritize your next steps, ensuring that you're always working on what matters most.

Streak Tracking

Build consistency and keep your motivation high with streak tracking. By visualizing your work habits over time, you can stay committed to your side projects and see your progress, reinforcing the discipline needed to achieve your goals.

Session History

Easily access your session history to track what you have accomplished. This feature allows you to reflect on your journey and identify patterns in your productivity, helping you make informed decisions about your future work sessions.

Detailed Stats

Gain insights into your productivity with detailed statistics that showcase your progress over time. This feature provides tangible proof of your efforts, enabling you to celebrate milestones and stay motivated as you build your side projects.

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.

Freelancers

Freelancers can maximize their limited work hours by using Session Stacker to set clear next steps for each project. This helps them maintain momentum across multiple clients and ensures no time is lost between sessions.

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.

How does Session Stacker help with productivity?

Session Stacker helps with productivity by eliminating the ramp-up time that often occurs when starting a work session. By defining your next task before you finish, you can jump right back into your work when you return.

Is Session Stacker suitable for large teams?

No, Session Stacker is specifically designed for individual builders and side hustlers. It focuses on personal productivity rather than managing large teams or complex project workflows.

Can I access Session Stacker on multiple devices?

Yes, Session Stacker is a Progressive Web App (PWA), meaning you can access it on any device with an internet connection, providing flexibility and convenience for users on the go.

What happens after the free trial ends?

After the 7-day free trial, you can choose to continue using Session Stacker for $4.99 per month or opt for a one-time payment of $49 for lifetime access. There are no hidden fees, and you can cancel anytime.
