About CloudLinux and PDFGrid

In their own words, as submitted to SaaSHub.

CloudLinux

PDFGrid

No description of CloudLinux yet.

PDFGrid extracts specific values from text-based PDFs and exports them to Excel or CSV. It's built for the case where you have a folder of documents in the same format — supplier invoices, purchase orders, delivery notes — and you need the same few fields out of every one of them. You define each...

CloudLinux 5 features

PDFGrid 11 features

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.

Visual Selector
Draw a box on the document to define what to extract. No code, no configuration files.
Nine Rule Types
Match by position on the page, by a nearby label, between two phrases, by regular expression, or by reading order.
Phrase Anchors
Find a value by the label beside it rather than its coordinates, so a rule survives layouts that shift between documents.
Reusable Templates
Define the fields once, then apply the same template to every document in that format.
Batch Processing
Apply a template across a whole folder of documents in one action.
Review Before Export
Every extracted value is visible, editable and removable before anything leaves the app.
Excel and CSV Export
Output straight to .xlsx or .csv. - Deterministic extraction — A rule engine, not a prediction model. The same document always returns the same values.
Runs in the Browser
Nothing to install, no server, no upload. Documents never leave the machine.
Works Offline
Once the page has loaded, extraction continues without a connection.
Password-protected PDFs
Enter the password in the app to open an encrypted document.
Account Not Required
No sign-up needed to use it. An account only saves templates between sessions.

Questions & Answers

As answered by people managing CloudLinux and PDFGrid.

What makes your product unique?

PDFGrid's answer:

PDFGrid runs entirely in your browser — no upload, no server, nothing to install — and it extracts by explicit rules rather than prediction, so the same document always returns the same values.

Most tools do one or the other. Desktop applications run locally but need installing and administrator rights. Cloud services need your documents. AI extraction tools produce a different answer on a different day and give you a confidence score instead of a reason.

PDFGrid is a rule engine you can open in a tab on a locked-down machine, and whose output you can check afterwards because there is nothing probabilistic in it.

Why should a person choose your product over its competitors?

PDFGrid's answer:

Choose it when your documents are text-based PDFs in recurring formats, you need the same handful of fields out of a lot of files, and you'd rather define the rules yourself than trust a model's judgement about which number was the total.

And choose it when your organisation can't send client documents to a third party at all — a constraint that rules out most of the market before accuracy is even discussed.

Practically: nothing to install, no account needed to try it, a template you build once and reuse, and every extracted value visible before you export.

How would you describe the primary audience of your product?

PDFGrid's answer:

People who receive the same kind of document over and over and need a few fields from each one in a spreadsheet — bookkeepers, accountants, accounts-payable and operations staff, logistics coordinators.

Usually not developers. There's no code, no API and nothing to install.

Usually small teams or sole practitioners rather than enterprises with a document ingestion platform. If you already have a pipeline, PDFGrid isn't trying to replace it.

And often people who can't use cloud extraction at all, because of client confidentiality or an internal policy that settles the question before anyone looks at features.

What's the story behind your product?

PDFGrid's answer:

I needed the same handful of fields out of a lot of similar PDFs, and everything I looked at fell into one of two groups.

The hosted tools wanted the documents on their servers, which isn't an option for a lot of the documents people actually have. The ones that ran locally were either developer libraries — write a parser, then maintain it forever — or they assumed every document was laid out identically, which stops being true on about the fourth file.

So I built the thing I wanted. Draw the fields on one document, save it as a template, apply it to the rest, check the results, export. It runs in the browser because that was the only way to do it without asking anyone to install software or trust me with their files.

Built and maintained by one person in the UK.

Which are the primary technologies used for building your product?

PDFGrid's answer:

TypeScript and React, built with Next.js and deployed as a static site
PDF.js for rendering documents in the browser
PDFium compiled to WebAssembly for text and geometry extraction, running on the user's own machine
ExcelJS for generating spreadsheets client-side
Supabase for authentication and saved templates — the only server-side component, and it never receives document contents
Cloudflare Pages for hosting
