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.

Questions & Answers

As answered by people managing Kostly and php eventloop.

What makes your product unique?

Kostly's answer

Kostly is a dish costing tool for professional kitchens. It shows you the real food cost of each dish, based on proper units of measurement, yields, and actual data โ€” not estimates.

Why should a person choose your product over its competitors?

Kostly's answer

Kostly only calculates cost when the data is sufficient. That's why every dish and subrecipe comes with a Cost Confidence indicator, so you know when you can trust the number and when it needs review.

How would you describe the primary audience of your product?

Kostly's answer

chef,restaurant,hotel

What's the story behind your product?

Kostly's answer

How the idea started

I'm a chef. And for years I made daily decisions about ingredients, menus, and prices โ€” without always having a clear picture of costs.

I knew what sold.

I knew what people liked. But often I didn't know what really made a profit.

What I saw in practice

In most of the restaurants I worked or collaborated with, costing was done:

roughly,

rarely,

usually in Excel.

The prices of the ingredients changed, but the food cost was not updated.

And so, dishes that we considered "strong" turned out to be loss-making in practice.

Not out of ignorance.

Out of lack of tools.

The real problem

The chef and the restaurateur are called upon to make critical decisions:

what goes on the menu

what goes out

what goes up in price

Without reliable data, these decisions are made on instinct.

And instinct is not enough for a sustainable business.

Why Kostly was created

Kostly was started to solve exactly this problem.

To have:

clear costing per dish,

real food cost,

a clear picture of profit,

without complex systems and without Excel.

A tool made from the kitchen to the business, not the other way around.

The vision

Starting in Greece, Kostly's goal is to help restaurants across Europe โ€” and internationally โ€” work with data, not assumptions.

Because a good dish deserves to be profitable.

Which are the primary technologies used for building your product?

Kostly's answer

Kostly is built using modern web technologies including React, TypeScript, Vite and Tailwind CSS for the frontend, Supabase for authentication, database and backend services, and Stripe for subscription management and payments. AI-powered features are integrated to automate invoice scanning, recipe analysis and food cost optimization.

Who are some of the biggest customers of your product?

Kostly's answer

Kostly is trusted by independent chefs, restaurants, cafรฉs, bars, hotels and hospitality businesses. As a growing SaaS platform, we're continuously expanding our customer base while helping food professionals simplify costing, improve profitability and save time.
