Features and specs

What each product offers, as listed by its team.

Preptics 6 features
CloudLinux 5 features
  • Score band and ranking
    Section and total bands with stated confidence, every attempt charted as a band rather than a point, per-skill loss analysis, skill estimates shown as ranges, pacing against the real module clocks, a routing map, an error profile, a written debrief, and your rank this season. The bands stay deliberately wide until there are enough real responses to narrow them honestly, and the calibration check exists so that narrowing can be earned rather than announced.
  • Adaptive mock exams
    Adaptive routing between modules, per-module clocks held on our server, the 10-minute break, module-locked navigation, and every tool the real test gives you including a graphing calculator. What is missing is the QUESTIONS. A full adaptive form needs six panels of verified items and we publish a form only when every panel is full
  • Dynamic Lessons and drills
    Live, and the largest finished thing on the platform: 30 skills, a micro-lesson each, answer-to-unlock recall, skill estimates shown as ranges, spaced review, drills that explain why each question was picked, and highlight-to-explain throughout. The honest gap is review the lessons have passed automated gates but have not been read end to end by a second human.
  • Dynamic Study plan
    The survey, the scheduling, the daily budget and the realism verdict all work, and the plan rearranges itself whenever your skill estimates change after drills, lessons and sittings alike. The one thing it cannot schedule yet is a full mock, because no mock is published those slot into the plan on the day the question bank lands, with no change needed here.
  • AI study help
    The mock debrief and highlight-to-explain both work today, on DeepSeek V4 Flash run by zero-data-retention hosts through OpenRouter fast enough that an answer arrives before you have finished re-reading the sentence with a hard per-account budget consumed before any request leaves. The larger tutor, one that can see your attempts and cite the explanations already written for your track, is not built. The search index it will need exists; the tutor is deliberately later than the budget and privacy rules that have to hold it up.
  • Leaderboards & seasons
    Rankings only count attempts sat under consistent conditions we would rather have a small honest leaderboard than a large meaningless one.
  • 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 Preptics and CloudLinux.

What makes your product unique?

Preptics's answer

Preptics sets itself apart through its advanced behavioral telemetry. Instead of just marking answers right or wrong, the platform tracks real-time micro-behaviors during practice exams—such as how you distribute your time, when you hesitate, and how you use the test's tools. It feeds this granular data into proprietary AI algorithms to dynamically update your lessons and targeted drills on the fly.

Additionally, Preptics moves away from static learning by offering draggable, interactive simulations (like widgets that let you physically manipulate slope and intercept in math problems) and provides an honest "score band" with stated confidence levels rather than guessing a single exact score.

Why should a person choose your product over its competitors?

Preptics's answer

Preptics directly addresses the "what next?" problem left by major competitors. As the site states: "Bluebook administers a test. Khan Academy teaches a course. Neither one tells you what to do tomorrow morning."

You should choose Preptics if you want:

  • Actionable Daily Plans: It takes your adaptive mock exam data and builds a customized daily plan sized perfectly to the actual study hours you have available.
  • Affordability: It aims to replace $150/hour private tutors with a highly accessible price point ($9.99 for a 3-month pass).
  • High-Quality, Verified Questions: Every AI-generated question is solved "blind" by multiple AI models that never see the answer key. Anything ambiguous is automatically discarded before a student ever sees it.

How would you describe the primary audience of your product?

Preptics's answer

The primary audience consists of high school students preparing for the Digital SAT who want a structured, highly efficient study routine. It is designed for students who struggle with knowing exactly what to study on a day-to-day basis, as well as self-driven learners looking for a premium, data-driven prep experience without the steep cost of a traditional private tutor.

What's the story behind your product?

Preptics's answer

Preptics is a brand-new educational startup built entirely around transparency and a disdain for industry guesswork. The founders are taking a radically honest approach to their launch. They publicly document their scoring methodology and openly refuse to post fake reviews to build hype, noting on their site: "We are new, and we would rather show you nothing than show you something we wrote ourselves." Their mission is to provide an "honest score" and a practical study roadmap rather than just selling test prep.

Who are some of the biggest customers of your product?

Preptics's answer

Because Preptics is a brand-new platform, they do not have large enterprise clients or a massive established user base to show off yet. Currently, their most important customers are a group of 50+ early beta testers who are actively using the platform to prep for the Digital SAT and helping the developers refine the system.

Which are the primary technologies used for building your product?

Preptics's answer

The primary technologies used to build Preptics integrate to form a modern, AI-driven web ecosystem. Here is how that specific stack powers the platform's features:

  • Next.js & Supabase: Serve as the core infrastructure. Next.js handles the dynamic application logic and routing, while Supabase provides the backend database and user management needed to track test sessions, store adaptive exam data, and manage accounts.
  • TailwindCSS & ShadCN: Power the frontend user interface. They provide the styling and component framework necessary to build the responsive study dashboards and the interactive, draggable simulations used in the skill drills.
  • Umami: Drives the platform's advanced behavioral telemetry. It acts as the analytics engine that captures granular, real-time data—such as time distribution, user hesitation, and specific tool usage during the mocks.
  • OpenRouter, DeepSeek, & OpenAI: Fuel the AI engines. These machine learning models and routing platforms provide the backend intelligence required to generate original questions, verify them blind, isolate knowledge gaps, and dynamically update personalized study plans.
