Possible disadvantages of OnlineOrNot

  • Limited Advanced Features
    While adequate for most needs, OnlineOrNot may lack some advanced features that specialized monitoring services provide.
  • 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.

php eventloop features and specs

  • Simple and lightweight
    The library provides a minimalistic implementation of an event loop in PHP, making it easy to understand and integrate into small projects without heavy dependencies.
  • Educational value
    As a straightforward PHP event loop implementation, it serves as a great learning resource for developers wanting to understand how event loops and asynchronous programming concepts work under the hood in PHP.
  • Non-blocking I/O support
    The library enables non-blocking I/O operations in PHP, allowing developers to handle multiple tasks concurrently without relying on multi-threading, which PHP does not natively support well.
  • Timer and periodic task support
    It provides built-in support for timers and periodic tasks, enabling developers to schedule recurring operations or delayed execution within the event loop.
  • Pure PHP implementation
    The library is written in pure PHP without requiring external C extensions, making it portable and easy to install across different PHP environments without special compilation steps.

Possible disadvantages of php eventloop

  • Limited community and support
    The project has a very small community with minimal stars, forks, and contributors on GitHub, which means limited peer support, fewer bug reports, and potentially slower issue resolution.
  • Not production-ready
    Given its small scale and limited adoption, the library may not be battle-tested enough for production environments where reliability, performance, and stability are critical.
  • Limited features compared to alternatives
    More established PHP async libraries like ReactPHP, AmpPHP, and others offer far more comprehensive ecosystems with HTTP servers, database clients, and stream handling that this library lacks.
  • Performance limitations
    Being a pure PHP implementation without leveraging extensions like ev, libuv, or swoole, the event loop may suffer from performance bottlenecks compared to extension-backed alternatives when handling high concurrency.
  • Poor documentation
    The repository has minimal documentation and examples, making it difficult for new users to understand the full API, edge cases, and best practices for using the library effectively.

  • 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 / 5 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 / 6 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 / 9 months ago
  • Ask HN: What Are You Working On? (October 2025)
    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 / 11 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 / 11 months ago
