Features and specs

What each product offers, as listed by its team.

UMLet 5 features
Opalstack 5 features
  • Simplicity
    UMLet offers a simple and intuitive user interface that is easy to navigate, making it suitable for beginners.
  • Open Source
    Being an open-source tool, UMLet is free to use and has a community-driven development approach, allowing users to contribute to its improvement.
  • Quick Diagramming
    The tool allows for quick and efficient creation of UML diagrams with minimal fuss and immediate visual feedback.
  • Lightweight
    UMLet is a lightweight application that doesn't consume significant system resources, ensuring smooth performance even on less powerful machines.
  • Integration
    It integrates well with various development environments and offers a standalone version, as well as an Eclipse plugin.

Possible disadvantages

  • Limited Features
    UMLet lacks some advanced features found in other UML tools, which might be necessary for complex modeling tasks.
  • Manual Updates
    Since UMLet is open-source, it may not have regular updates or support services, leading to potential issues with bugs or compatibility over time.
  • Basic Graphics
    The graphical capabilities are quite basic compared to more sophisticated UML tools, which might be a limitation for users needing high-quality visuals.
  • Learning Curve for Customization
    While simple to use for basic tasks, customizing UMLet to suit specific needs can involve a learning curve, particularly for new users.
  • Limited Collaboration
    UMLet may not offer robust real-time collaboration features, which can be a drawback for teams working on shared UML diagrams.
  • Developer-Friendly Hosting
    Opalstack is designed with developers in mind, offering SSH access, Git integration, and support for multiple programming languages and frameworks including Python, Node.js, Ruby, and PHP, giving developers granular control over their hosting environment.
  • Affordable Pricing
    Opalstack offers competitive pricing for shared and managed hosting plans, making it an accessible option for small businesses, freelancers, and individual developers who need robust features without enterprise-level costs.
  • Modern Control Panel
    Opalstack provides a clean, modern, and intuitive web-based dashboard for managing sites, applications, databases, and email accounts, which is a significant improvement over older-style hosting control panels like cPanel.
  • Strong Support for Multiple Applications
    The platform supports a wide variety of application types including WordPress, Django, Flask, Express, static sites, and more, allowing users to host diverse projects on a single account with easy deployment.
  • Reliable Infrastructure and Support
    Opalstack is built by former WebFaction team members, bringing experienced hosting expertise. They offer responsive customer support and a reputation for stable, well-managed server infrastructure with good uptime.

Possible disadvantages

  • Smaller Community and Ecosystem
    Compared to major hosting providers like DigitalOcean, AWS, or even shared hosts like SiteGround, Opalstack has a smaller user base, which means fewer community tutorials, third-party guides, and forum discussions available for troubleshooting.
  • Limited Scalability Options
    Opalstack is primarily a shared hosting provider, which means it may not be the best choice for high-traffic applications or projects that require rapid, on-demand scaling of resources like CPU, RAM, or storage.
  • Not Ideal for Beginners
    While developer-friendly, Opalstack's approach can be intimidating for non-technical users. Setting up applications often requires familiarity with the command line and server configuration, which may not suit those looking for simple one-click solutions.
  • Limited Data Center Locations
    Opalstack offers a relatively small number of data center locations compared to major cloud providers, which may result in higher latency for users targeting audiences in regions not well-served by the available server locations.
  • Fewer Managed Services and Add-ons
    Unlike larger hosting platforms, Opalstack lacks a wide range of managed add-on services such as built-in CDN integration, managed backups with granular restore options, or one-click SSL management that more mainstream providers offer out of the box.

  • Is there any free handy tool to create UML diagrams ?
    I like Umlet. It is a GUI drawing tool, but is not overbearing. Since I like to abuse the details of UML graphical notation, Umlet lets me type anything in a class "box" I like. Source: over 3 years ago
