About PricingFast.st and CloudLinux

In their own words, as submitted to SaaSHub.

PricingFast.st
CloudLinux

PricingFast lets you A/B test the price of a Stripe product on real visitors. You connect Stripe with OAuth and your plans get imported. Then you say what to try in one sentence, for example "+20% for half of new visitors", and PricingFast computes rounded test prices from the plans you already...

  • Apply Automatically
    Apply the winner and it becomes the plan's price in Stripe; current subscribers keep what they pay
  • 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 PricingFast.st and CloudLinux.

Which are the primary technologies used for building your product?

PricingFast.st's answer

Next.js, Supabase (Postgres), Stripe Connect and Checkout, Vercel, an MCP server, PostHog.

Who are some of the biggest customers of your product?

PricingFast.st's answer

None yet: PricingFast launched recently and has no paying customers to name.

What makes your product unique?

PricingFast.st's answer

It A/B tests the price itself on Stripe, not a page design. Each visitor sees one price and pays exactly that price at Stripe Checkout. The winner is picked by revenue per visitor, not by conversion rate. Your coding agent installs it over MCP, and nothing goes live until you press Launch.

Why should a person choose your product over its competitors?

PricingFast.st's answer

Generic A/B tools know nothing about revenue. Pricing tools for mobile apps (RevenueCat, Superwall) don't work for web SaaS. PricingFast is built for SaaS on Stripe. Setup takes one sentence ("+20% for half of new visitors"). You check both prices on localhost before going live. Once a price wins, you apply it in one click, and people already subscribed keep their current price. The first test is free.

How would you describe the primary audience of your product?

PricingFast.st's answer

Indie founders and small SaaS teams who bill through Stripe, get steady traffic on their pricing page, and suspect their price is too low.

What's the story behind your product?

PricingFast.st's answer

Changing a price is stressful because you only get one try. If sales drop afterwards, you can't tell whether the price caused it or it was just a slow month. Mobile apps solve this by showing two prices at the same time, but web SaaS on Stripe had no simple way to do it. So I built one.
