Features and specs

What each product offers, as listed by its team.

WTM API 6 features
CloudLinux 5 features
  • HTML to Markdown Conversion
    Convert any webpage to clean, structured Markdown with a single POST request. Headings, bold, italic, links, and images all preserved.
  • Table Preservation
    HTML tables are converted to proper Markdown tables, keeping data structured and readable.
  • Code Block Detection
    Code blocks are preserved with syntax language hints. Perfect for extracting documentation and tutorials.
  • Absolute URL Resolution
    All relative links and image URLs are automatically resolved to absolute URLs based on the source page.
  • Sub-Second Response
    Average response time under 1 second. Server-side HTML parsing with Cheerio — no headless browser overhead.
  • Live Demo
    Try the API directly on the website. 3 free conversions without signing up. Paste any URL and see the Markdown output instantly.
  • 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.

Analysis

An editorial look at what each product does well and who it suits.

WTM API
CloudLinux

Overall verdict

  • WTM API appears to be a niche data/API service, but without verified, independent, up-to-date information confirming its reliability, uptime, pricing transparency, or customer support quality, it's not possible to give a confident endorsement. Prospective users should conduct due diligence, test the API with a trial or sandbox account, and verify documentation quality and support responsiveness before committing.

Why this product is good

  • Limited independent reviews or third-party benchmarks are readily available to verify claims of performance and reliability.
  • Pricing and feature transparency should be confirmed directly on their site since public information is sparse.
  • API-based services can vary widely in documentation quality, so checking their developer docs firsthand is essential.
  • Support responsiveness and SLA guarantees are not well-documented externally, so direct testing is recommended.

Recommended for

  • Developers who are willing to test the API firsthand via a trial before committing.
  • Businesses needing a specific niche data feed that WTM API claims to provide, provided they verify data accuracy first.
  • Technical teams comfortable evaluating API uptime and documentation quality independently.
  • Not recommended for mission-critical production use without a thorough vetting period.

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 WTM API and CloudLinux.

What makes your product unique?

WTM API's answer

WTM API focuses on structure preservation, not just text extraction. Unlike most scrapers that return raw text, it converts HTML to proper Markdown with headings, tables, code blocks, and links intact. No headless browser needed — pure server-side parsing means sub-second responses at a fraction of the cost.

Why should a person choose your product over its competitors?

WTM API's answer

Speed and simplicity. One POST call, any URL, clean Markdown back in under 1 second. No SDKs to install, no headless browser to maintain, no complex configuration. Generous free tier (50 calls/month) and straightforward pricing. The output is immediately usable for LLMs, RAG pipelines, or content migration.

How would you describe the primary audience of your product?

WTM API's answer

Developers building AI/LLM applications, RAG pipelines, content migration tools, or any system that needs web content in a structured, portable format. Also useful for teams moving content to Markdown-based platforms like Notion, Obsidian, or static site generators.

What's the story behind your product?

WTM API's answer

I was building a RAG pipeline and needed web content in Markdown format. Existing tools gave me either raw text (losing all structure) or required a headless browser (slow and expensive). I built WTM API to solve my own problem - a fast, simple API that preserves the structure of any webpage as clean Markdown. Shipped the MVP in a weekend using Next.js, Supabase, Stripe, and Vercel, all on free tiers.

Which are the primary technologies used for building your product?

WTM API's answer

Next.js 16 (App Router), Supabase (auth and PostgreSQL), Stripe (subscription billing), Vercel (hosting), and Cheerio (server-side HTML parsing). The entire stack runs on free tiers with zero monthly infrastructure cost.

Who are some of the biggest customers of your product?

WTM API's answer

  • Early-stage AI startups building RAG pipelines
  • Independent developers working on content tools
  • Currently in public beta and growing the user base
