Possible disadvantages of OnlineOrNot

  • Support Availability
    Customer support options may be limited, particularly for lower-tier plans, which could be a drawback for users requiring immediate assistance.
  • Scalability Issues
    The platform might not be as scalable as some competitors, which could pose challenges for very large enterprises needing to monitor a vast number of sites.
  • Learning Curve
    Despite its user-friendly interface, some users may still face a learning curve when first getting started with the platform.
  • Dependency on Internet
    As an online service, OnlineOrNot itself depends on having a reliable internet connection, which could be a drawback if users have unstable internet access.

React Complex Tree features and specs

  • Customizability
    React Complex Tree offers a high degree of customizability, allowing developers to tailor the tree component to fit their specific needs. This can be especially useful for creating unique UI experiences.
  • Feature-Rich
    The library includes a wide range of features out of the box such as drag-and-drop support, keyboard navigation, and dynamic data loading, which can save development time.
  • Accessibility Support
    React Complex Tree is designed with accessibility in mind, providing support for ARIA attributes and keyboard interactions, which helps ensure that applications are usable by people with disabilities.
  • Performance
    The component is optimized for performance, handling large data sets efficiently without significant slowdowns, which is critical for applications that manage extensive hierarchical structures.
  • Community and Documentation
    The library has a supportive community and well-structured documentation, providing developers with ample resources to troubleshoot and extend its functionality.

Possible disadvantages of React Complex Tree

  • Complexity
    Due to its extensive features and customizability, React Complex Tree can be complex to set up and configure properly, which may lead to a steeper learning curve for new users.
  • Bundle Size
    As a feature-rich component, React Complex Tree can increase your bundle size, which might be a concern for projects where performance and loading time are critical.
  • Third-Party Dependency
    Relying on a third-party library introduces dependencies outside of your control, which may present challenges in terms of long-term maintenance and potential update or deprecation issues.
  • Specific Use Case Tailoring
    While it offers a lot of features, developers may find that very specific use cases require additional effort to customize or extend the component beyond its intended use.

  • Ask HN: What are you working on? (April 2026) (Non AI)
    Still OnlineOrNot (https://onlineornot.com/) - I've been working on adding more and more configurability to the browser checks feature. More recently, I've made it so you can drop your existing playwright test suites into the code editor, and it'll Just Work. A whole bunch more work to do around that, but I think letting folks drop code in makes more sense than continuously updating the UI. - Source: Hacker News / 4 months ago
  • Ask HN: What Are You Working On? (March 2026)
    I've been celebrating five years of working on OnlineOrNot (https://onlineornot.com/) by adding more features for teams that build software: - 2FA, PassKey, and password-based login for folks that hate magic links - Moved my entire API from GraphQL to REST so I can fully dogfood the API I offer - Added an audit log as standard on all plans - Built a terraform provider... - Source: Hacker News / 5 months ago

    OnlineOrNot (https://onlineornot.com) Planning on wrapping up the year with a year in review post (thankfully I've been writing monthly updates as I go, should save some time). Apart from that, clearing up tech debt that helped me ship fast, but was ultimately a bad fit for the business (Next.js and GraphQL). - Source: Hacker News / 8 months ago

    Still a one-person project (since 2021): https://onlineornot.com I'm still rebuilding OnlineOrNot's frontend to be powered by the public REST API. Uptime checks are now fully powered by a public API (still have heartbeat checks, maintenance windows, and status pages to go). Doing this both as a means of dogfooding, and adding features to the REST API that I easily dumped into the private GraphQL API without... - Source: Hacker News / 10 months ago
  • Ask HN: What Are You Working On? (September 2025)
    I'm rebuilding OnlineOrNot's frontend to be powered by the public REST API. Doing this both as a means of dogfooding, and adding features to the REST API, that I easily dumped into the private GraphQL API without thinking too hard. Basically I've realised GraphQL has taken me as far as it can, and I should've gone with REST to start with. That, and after I finish the first milestone (uptime checks + cron job... - Source: Hacker News / 10 months ago
