Features and specs

What each product offers, as listed by its team.

DocuSmartly 8 features
CloudLinux 5 features
  • Client-Side Processing
    Sign, split/merge, compress, page extract and images-to-PDF run entirely in your browser — those files are never uploaded to a server.
  • No Sign-Up Required
    Everyday tools — compress, merge, split, sign, convert — work without an account, email or watermark.
  • PDF form auto-fill
    Save your details once — name, address, ID numbers — then auto-fill any PDF form. AI matches your saved fields to the form's fields.
  • Smart Auto-Split
    Scanned a stack of documents into one PDF? It finds the boundaries automatically using blank separator pages and orientation changes.
  • Target-size Compression
    Compress to a specific size limit — 100 KB, 200 KB, 500 KB — for exam portals and government form uploads that reject larger files.
  • AI data extraction
    Describe the fields you need and export structured data from invoices, catalogs, statements or certificates to Excel or JSON.
  • OCR for scanned documents
    Recognises text in scanned PDFs and photos in the browser, producing searchable, selectable text.
  • 16+ tools in one place
    Compress, merge, split, sign, edit, protect, repair, OCR, images-to-PDF, PDF to/from Word, Excel and PowerPoint, form auto-fill and AI data extraction.
  • 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 DocuSmartly and CloudLinux.

What makes your product unique?

DocuSmartly's answer

Most online PDF tools upload your file to a server to do the work. DocuSmartly does the opposite wherever it can: signing, splitting, merging, compressing, extracting pages and images-to-PDF all run inside your browser using client-side JavaScript, so the file never leaves your computer. Only conversions that genuinely need a document engine — Word/Excel/PowerPoint to PDF, PDF to Word — and AI extraction go to a server, and we say so plainly instead of hiding it.

The second difference is focus. Alongside the usual PDF tools there are workflows built for real Indian paperwork: compressing to an exact size limit for exam portals, self-attesting documents, and a form auto-fill that remembers your details once and completes any PDF form.

How would you describe the primary audience of your product?

DocuSmartly's answer

Primarily India. Students and job applicants dealing with exam-portal and government-form uploads that reject files over a fixed size, people who need documents self-attested or signed without a printer, and small business owners and freelancers handling invoices, rent agreements and vendor forms.

Beyond that, anyone who does not want to upload a personal document — an ID, a contract, a bank statement — to someone else's server just to sign or split it.

Which are the primary technologies used for building your product?

DocuSmartly's answer

Frontend: vanilla JavaScript, no framework. pdf-lib for all client-side PDF manipulation, Tesseract compiled to WebAssembly for in-browser OCR, JSZip for multi-file output.

Backend: Python 3.11 and Flask, with PyMuPDF and pdf2docx for high-fidelity PDF-to-Word, python-docx and openpyxl for document generation, OCRmyPDF and Ghostscript for scanned PDFs, LibreOffice for Office-to-PDF conversion, and qpdf for encryption.

Infrastructure: Docker on Railway, PostgreSQL, Razorpay for payments, Google Sign-In for auth.

What's the story behind your product?

DocuSmartly's answer

For nine years I worked a corporate job — long hours, and by 2025 I wasn't happy in it. A difficult stretch at work became the push I needed, and I started teaching myself to code.

DocuSmartly was meant to be a practice project. Nothing more. But as I built it I kept running into how much friction sits inside ordinary paperwork — a portal that rejects your form because the file is 40 KB too large, a document that needs signing when you don't own a printer. Somewhere along the way it stopped being an exercise and started being something that could genuinely make someone's day easier.

That is why there is a feedback button on every page. I am one person building this, and what users report actually changes the product — one bug report revealed that PowerPoint and Excel conversions had been silently broken in production, and it was fixed because someone took the time to tell me.

I would like DocuSmartly to become the PDF tool people reach for first. If you use it and something annoys you, tell me. That is how it gets there.

Who are some of the biggest customers of your product?

DocuSmartly's answer

DocuSmartly is used by individuals, not sold to organisations, so there is no customer list to publish here.

Most of the tools work without an account at all — no sign-up, no email. That is deliberate, and it means there is no name attached to the work someone does on the site. A list of "biggest customers" would run against the whole point of building it this way.

Why should a person choose your product over its competitors?

DocuSmartly's answer

Three practical reasons.

No account, no watermark, no daily task limit on the everyday tools — compress, merge, split, sign. You open the page and use it.

Privacy you can verify. For the client-side tools you can open your browser's network tab and watch that your file is never uploaded. That is a stronger guarantee than a privacy policy promising files are "deleted after an hour".

Tools the others do not have: a PDF form auto-fill that stores your details once and matches them to any form's fields, compression to an exact target size for portal upload limits, and a Smart Auto-Split that finds document boundaries in a scanned stack automatically.
