Possible disadvantages of Notion

  • Performance Issues
    Some users report that Notion can become slow or experience lag, especially with large databases and complex pages.
  • Offline Limitations
    While Notion offers some offline capabilities, its functionality is significantly reduced without an internet connection, which can be inconvenient for some users.
  • Pricing for Teams
    Though Notion offers a free version, its premium plans can be expensive for larger teams, which may be a constraint for startups or small businesses.
  • Privacy Concerns
    As with any cloud-based service, there are potential privacy and data security concerns, especially for users handling sensitive information.

PlantUML features and specs

  • Simple Syntax
    PlantUML uses a plain text language that is easy to learn, making it accessible for both technical and non-technical users.
  • Quick Diagram Creation
    Due to its straightforward text-based syntax, diagrams can be created and modified quickly without the need for a graphical interface.
  • Version Control Friendly
    Diagrams are stored as text files, making them easy to manage with version control systems like Git.
  • Integrations
    PlantUML integrates well with many other tools and platforms including IDEs (e.g., IntelliJ, VSCode), documentation generators (e.g., Doxygen, Sphinx), and project management tools.
  • Wide Range of Diagrams
    PlantUML supports a variety of UML and non-UML diagrams, including sequence diagrams, use case diagrams, class diagrams, and more.
  • Open Source
    PlantUML is an open-source tool, which makes it free to use and allows for community contributions and extensions.

Possible disadvantages of PlantUML

  • Learning Curve
    While the syntax is simple, users unfamiliar with text-based diagramming may need time to become proficient.
  • No GUI
    PlantUML lacks a graphical user interface (GUI), which might be a disadvantage for users who prefer drag-and-drop diagram creation.
  • Complex Diagrams
    For very complex diagrams, the text-based syntax can become cumbersome and hard to manage.
  • Rendering Limitations
    The style and formatting options are less flexible compared to some dedicated graphical diagramming tools.
  • Performance
    For large diagrams, the text-to-diagram rendering process can be slow.
  • Security Concerns
    Using PlantUML with remote server options might raise security issues, particularly when dealing with sensitive information.

    Notion has helped in documenting our business

    It's been very very helpful to streamline different people on our team, especially remote workers to help them understand what's going on in our business without 100s of meetings.

    👍 Pros:    Ui is very attractive|Easy to use|Great for collaboration|Good customer service|Free to use
    👎 Cons:    Steep learning curve

    Extremely helpful- made life easier

    My remote-first start-up has eliminated more than 200+ hours of meetings and 1000s of mismanaged documents because our entire communication happens through Notion.

    👍 Pros:    Clean ui|File sharing|Modular
    👎 Cons:    Learning curve

    As someone who's always on the lookout for the perfect productivity app, I was excited to try out Notion. It promises to be an all-in-one tool for everything from note-taking to project management to personal wikis.

    From the moment you open Notion, you can tell that it's different from other productivity apps. The interface is sleek and modern, and it's easy to navigate. The app is divided into pages, which can be customized with different templates to fit your needs. You can create to-do lists, databases, wikis, calendars, and more.

    One of the things I love about Notion is the ability to create relationships between pages. For example, you can create a database of your favorite books and then link to a page with your book reviews. Or you can create a to-do list and link to a page with notes about the task. This feature makes it easy to keep all of your information in one place and to connect related items.

    🏁 Competitors: Microsoft Loop
    👍 Pros:    Highly customizable|All in one|Collaboration|Cross platform
    👎 Cons:    Steep learning curve

Software Diagrams - Plant UML vs Mermaid
For C4 Models, Mermaid support is still experimental. This shows as you have little control over the way the diagram is rendered, and some parts are unreadable (i.e., arrows over nodes). PlantUML works as you would expect and has support for more advanced setup like sprites. Not even close on this one. Winner: PlantUML
