  • Free Unanswered Calls
    Calls that aren't answered aren't charged.
  • Crypto Payments
    Top up via Bitcoin, Ethereum, USDT, and 70+ other cryptocurrencies (via NOWPayments), alongside standard card payments.
  • No Tracking
    No third-party trackers or ad cookies; GDPR-compliant, call records deleted after 60 days.
  • Enhanced Server Stability
    CloudLinux uses its lightweight virtualization technology (LVE) to isolate each tenant on a shared hosting server, preventing any single user from consuming excessive resources and crashing the server for everyone else. This ensures consistent uptime and performance.
  • Improved Security with HardenedPHP and KernelCare
    CloudLinux offers HardenedPHP, which patches old and unsupported PHP versions against known vulnerabilities, and KernelCare, which provides live kernel patching without requiring server reboots. These features significantly enhance server security posture.
  • Resource Limit Management
    Administrators can set granular resource limits (CPU, memory, I/O, number of processes, etc.) per user account using LVE Manager. This makes it easy to manage shared hosting environments and ensure fair resource distribution among tenants.
  • CageFS File System Virtualization
    CageFS creates a virtualized file system for each user, preventing them from seeing other users on the server, viewing sensitive configuration files, or exploiting server vulnerabilities. This adds an important layer of isolation and security.
  • Wide Compatibility with Hosting Panels
    CloudLinux integrates seamlessly with popular hosting control panels such as cPanel, Plesk, and DirectAdmin, making it straightforward for hosting providers to adopt without overhauling their existing infrastructure or workflows.

Possible disadvantages

  • Additional Licensing Cost
    CloudLinux requires a paid monthly or annual license on top of the base server cost. For smaller hosting providers or individual server owners, this additional expense can add up and may not always be justifiable compared to free alternatives.
  • Limited to CentOS/RHEL-Based Systems
    CloudLinux is built on top of RHEL/CentOS and does not support other Linux distributions like Ubuntu or Debian. This limits its adoption for hosting providers who prefer or already run non-RHEL-based environments.
  • Learning Curve for Configuration
    While CloudLinux provides powerful resource management tools, properly configuring LVE limits, CageFS, PHP Selector, and other features requires a solid understanding of the platform. Misconfiguration can lead to users being unnecessarily restricted or resources being poorly allocated.
  • Potential Performance Overhead
    The additional layers of virtualization, resource monitoring, and file system isolation introduced by CloudLinux can impose a slight performance overhead on the server compared to running a bare, unmodified Linux distribution without these controls.
  • Dependency on CloudLinux Ecosystem
    Adopting CloudLinux means relying on their ecosystem for kernel updates, PHP patches, and security fixes. If the company experiences delays in releasing patches or changes its pricing/licensing model, hosting providers may find themselves locked into a dependency that is difficult to migrate away from.

Overall verdict

  • CloudLinux is a well-regarded, mature Linux OS distribution and toolset specifically designed for shared hosting and multi-tenant server environments, offering strong isolation, resource management, and security features that make it a solid choice for hosting providers.

Why this product is good

  • Provides LVE (Lightweight Virtual Environment) technology for per-tenant resource isolation, preventing 'bad neighbor' effects on shared servers
  • Enhances server stability and security by isolating users so that one account's issues (crashes, resource spikes) don't affect others
  • Offers extended lifecycle support (longer than standard CentOS/RHEL support windows), which is valuable for legacy systems
  • Includes tools like CloudLinux OS Shield, Imunify360 integration, and hardened kernel options for improved security
  • Compatible with popular control panels like cPanel and Plesk, making it easy to integrate into existing hosting stacks
  • Backed by an established company with a long track record in the hosting industry and responsive support
  • Offers granular control over CPU, memory, I/O, and other resources per user account
  • Provides PHP Selector and multiple PHP version support, useful for hosting providers serving diverse client needs

Recommended for

  • Web hosting companies running shared or reseller hosting environments
  • Hosting providers needing to isolate customer accounts on the same physical server
  • Businesses requiring extended OS support lifecycles beyond standard RHEL/CentOS EOL dates
  • Enterprises using cPanel or Plesk that want tighter security and resource control
  • Hosting companies looking to reduce support tickets caused by noisy-neighbor resource contention
  • IT teams managing multi-tenant infrastructure who need governance and monitoring tools built into the OS layer

Questions & Answers

As answered by people managing PuchiDen.app and CloudLinux.

What makes your product unique?

PuchiDen.app's answer

PuchiDen lets you place international calls straight from a browser tab — no app to install, no SIM card, and no account tied to your real phone number. It targets calls that usually require a real phone line (banks, government offices, embassies) rather than casual VoIP chat, and keeps pricing pay-per-minute with no subscription lock-in.

Why should a person choose your product over its competitors?

PuchiDen.app's answer

Most international calling apps require an install and tie you to a subscription. PuchiDen works entirely in-browser, charges only for connected minutes (unanswered calls are free), and covers 180+ countries at rates it claims run up to 95% cheaper than standard carrier IDD. It also doesn't track users and provide full privacy.

How would you describe the primary audience of your product?

PuchiDen.app's answer

People who occasionally need to reach an overseas landline or official phone line — banks, embassies, government offices, airlines, customer service — but don't want a permanent international calling app or SIM. Useful for expats, travelers, immigrants dealing with paperwork abroad, and remote workers contacting overseas clients.

What's the story behind your product?

PuchiDen.app's answer

Founder Iqbal Abdullah built PuchiDen after Skype was retired in May 2025 and its replacements — Teams, WhatsApp, LINE — all required both people to install the same app just to make one phone call. Iqbal spent nearly 20 years in telephony infrastructure (SMS-to-email, SIP, WebRTC), starting Xoxzo in 2007 and running it for 14 years before its 2021 acquisition, so he had already solved the hard parts (codecs, NAT traversal, carrier routing, call quality). PuchiDen was built as a "public phone for the internet" in that spirit: no app, no account, no tracking — modeled after how a 1990s payphone worked, where you just picked up and dialed without the phone needing to know who you were. The name combines "puchi" (プチ, from French petite — small, casual) and "den" (電, from denwa/telephone) — literally "a small phone."

Which are the primary technologies used for building your product?

PuchiDen.app's answer

PuchiDen is built on WebRTC for in-browser calling, bridged to the public telephone network (PSTN) via SIP — the same telephony fundamentals (codecs, NAT traversal, carrier routing) the founder spent over a decade solving at Xoxzo. The web app itself avoids third-party trackers or analytics scripts by design.

Who are some of the biggest customers of your product?

PuchiDen.app's answer

PuchiDen serves individual consumers rather than enterprise accounts, so we don't disclose customer names or identities. Our users are largely people making occasional international calls — travelers contacting hotels, clinics, or embassies abroad; people calling family overseas on regular landlines; small business owners and remote workers reaching clients or banks in other countries; and former Skype users who lost their go-to option when it was retired in 2025.
