Features and specs

What each product offers, as listed by its team.

FastBill 5 features
CloudLinux 5 features
  • Easy Invoicing
    FastBill offers a streamlined and intuitive invoicing system that allows freelancers and small businesses to create, send, and manage professional invoices quickly with minimal effort.
  • Automated Bookkeeping
    The platform automates many bookkeeping tasks such as expense tracking, bank transaction matching, and receipt scanning, saving users significant time on financial administration.
  • German Tax Compliance
    FastBill is specifically designed for the German market and complies with GoBD regulations, making it an excellent choice for German freelancers and small businesses who need to meet local tax and accounting standards.
  • User-Friendly Interface
    The platform features a clean, modern, and intuitive interface that makes it accessible even for users without accounting or bookkeeping experience, reducing the learning curve considerably.
  • Integration with Tax Advisors
    FastBill allows users to easily export data and share access with their tax advisors (Steuerberater), facilitating seamless collaboration for tax filing and financial reporting via DATEV integration.

Possible disadvantages

  • Limited to German Market
    FastBill is primarily designed for the German-speaking market and German tax regulations, making it less suitable for international businesses or companies operating outside of Germany, Austria, or Switzerland.
  • Limited Advanced Features
    Compared to more comprehensive accounting solutions, FastBill lacks some advanced features such as detailed project management, payroll processing, and complex multi-currency support that growing businesses may need.
  • Pricing for Small Users
    While functional, the subscription costs can feel high for very small freelancers or sole proprietors with minimal invoicing needs, especially when compared to free or cheaper basic invoicing tools.
  • Limited Integrations
    FastBill has a relatively limited ecosystem of third-party integrations compared to larger competitors like Lexoffice or sevDesk, which can be a drawback for businesses relying on multiple software tools.
  • No Full Double-Entry Accounting
    FastBill focuses on simplified bookkeeping and invoicing rather than full double-entry accounting, which means businesses that require comprehensive accounting capabilities may eventually outgrow the platform.
  • 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.
