Caller vs Perkoon

Pay-As-You-Go Pricing

Caller operates on a flexible pay-as-you-go pricing model, starting at just $0.02 per minute. This means users only pay for the minutes they use, eliminating the burden of monthly fees and subscriptions. With transparent pricing, there are no hidden costs, ensuring that you know exactly what you're charged for.

Global Coverage

With the capability to connect over 200 countries worldwide, Caller provides extensive global coverage. This feature allows users to reach both landlines and mobile phones in major destinations, facilitating international communication like never before. Whether for personal or business use, Caller ensures you can connect wherever you need to.

HD Voice Quality

Caller guarantees crystal-clear audio quality powered by enterprise-grade infrastructure. This feature allows for seamless conversations, making users feel as though they are speaking face-to-face. The HD voice quality enhances user experience, ensuring that important conversations are clear and professional.

Instant Connection

Forget about long setup times and complicated configurations. Caller enables instant connections directly from your web browser. Just enter the phone number and start calling within seconds—no downloads or installations required. This feature is perfect for users who need quick and efficient communication.

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.

International Business Calls

For businesses that operate globally, Caller is an essential tool for making international calls without incurring hefty fees. Sales teams can easily reach clients and partners around the world, facilitating smoother communication and stronger relationships.

Remote Team Communication

With more teams working remotely, Caller provides an effective solution for communication among team members. Its browser-based calling enables instant connection, allowing remote workers to collaborate seamlessly and stay in touch without the hassle of traditional calling methods.

Personal Calls Abroad

For individuals with family and friends living overseas, Caller offers a cost-effective way to stay connected. Users can make personal calls without worrying about high international rates, ensuring that they maintain relationships with loved ones no matter where they are.

Customer Support Services

Businesses can utilize Caller for their customer support lines, providing customers with an easy way to reach them. With HD voice quality and a dedicated phone number option, companies can enhance their professional image while ensuring clear communication with clients.

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.

Its flagship offering is unlimited, free P2P transfer that beams files directly between browsers with no size caps and no middleman—your data never touches Perkoon's servers, ensuring true privacy and keeping the service free forever.

How do I get started with Caller?

Getting started with Caller is simple. Just sign up for a free account, which takes seconds and does not require a credit card. Once registered, add credits to your account and start calling instantly.

Are there any contracts or hidden fees?

No, Caller operates on a pay-as-you-go model, meaning there are no contracts, monthly fees, or hidden charges. You only pay for the minutes you use, making it a transparent and cost-effective choice.

Can I use Caller on any device?

Yes, Caller is designed to work seamlessly across all devices with a web browser. Whether you are using a computer, tablet, or smartphone, you can make calls without the need for additional software.

Is my data secure with Caller?

Absolutely. Caller employs bank-level encryption for all calls and transactions, ensuring that your conversations and payment information are kept secure and private at all times.

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.
