Drop in plain text, a flyer photo, a public events page URL, a CSV, or an existing calendar file. Calfeed reads it and builds the feed. You get one stable link that works in Apple Calendar, Google Calendar, Outlook, Microsoft 365, and Yahoo.

Edit once, everyone gets it. Change a time in Calfeed and every subscriber's calendar updates on its own โ€” no re-share, no message blast, same link forever.

Make it yours: drop in a logo and a color, and the public page looks like your brand. Embed it on your site with a single snippet that auto-resizes and stays in sync.

Built for parents managing kid schedules, coaches and trainers running classes, organizers coordinating community events, and creators who post regular content. Anyone who keeps repeating "here's the updated schedule" stops repeating it.

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.

Analysis of Calfeed

Overall verdict

  • I don't have verified, up-to-date information about Calfeed (calfeed.ai) specifically, so I can't confirm its quality, features, or reliability. It may be a newer or niche tool that isn't well-documented in my training data. Before relying on it, check independent reviews, user feedback, its security practices, and whether it delivers on its stated claims.

Why this product is good

  • No verified information available about this specific product's features or performance
  • Unable to confirm reliability, pricing fairness, or user satisfaction
  • Cannot verify company legitimacy, data security practices, or customer support quality
  • Recommend checking recent reviews on sites like G2, Trustpilot, or Reddit for real user experiences

Recommended for

  • Users who have already done independent research and verified the tool meets their needs
  • Those comfortable testing new or lesser-known tools with appropriate caution
  • Not recommended as a blind choice without further due diligence

Analysis of php eventloop

Overall verdict

  • php-eventloop is a lightweight event loop implementation for PHP that provides a solid, minimalistic solution for developers wanting to implement asynchronous, non-blocking behavior without adopting a full framework like ReactPHP or Amp. It's good for learning purposes and simpler use cases, though it lacks the extensive ecosystem, tooling, and production hardening of more established async libraries.

Why this product is good

  • Lightweight and simple to understand, making it easy to integrate into small projects
  • Useful for learning how event loops work under the hood in PHP
  • Minimal dependencies compared to larger async frameworks
  • Open source and available for inspection/modification on GitHub
  • Can be a good starting point for building custom async solutions

Recommended for

  • Developers learning about event-driven programming in PHP
  • Small projects needing basic async functionality without heavy dependencies
  • Educational purposes and understanding event loop internals
  • Prototyping simple non-blocking I/O operations
  • Developers who want full control over a minimal event loop implementation

Questions & Answers

As answered by people managing Calfeed and php eventloop.

What makes your product unique?

Calfeed's answer

Calfeed is the only calendar tool built AI-first โ€” paste a schedule in plain text (or drop a flyer photo, URL, or CSV) and get a shareable feed back. Every competitor still uses one-event-at-a-time form fields built for the Outlook 97 era.

Why should a person choose your product over its competitors?

Calfeed's answer

Calfeed turns "here's the updated schedule" into a one-time subscription instead of a recurring group text. Tools like AddEvent and AddCal still make you fill out a form per event; Calfeed reads what you already have and publishes a feed that updates itself.

How would you describe the primary audience of your product?

Calfeed's answer

Anyone who keeps re-sharing the same schedule: parents tracking kid sports and school events, coaches and trainers running classes, organizers coordinating community events, and creators with regular programming. Pro/creator users layer on logos, custom colors, and embeds for a branded public page.

What's the story behind your product?

Calfeed's answer

Built after watching the same friction play out everywhere โ€” coaches retyping practice changes, parents juggling four kid calendars, organizers blasting "updated schedule" texts. The fix wasn't a better form; it was treating a schedule as text the way humans actually write it, and a calendar as a feed the way subscribers actually consume it.

Which are the primary technologies used for building your product?

Calfeed's answer

Next.js 16 + React 19 + Tailwind on Vercel, Postgres via Neon with Drizzle ORM, Stripe for billing, Resend for transactional email, and Anthropic Claude for turning plain text into structured events.

Who are some of the biggest customers of your product?

Calfeed's answer

The biggest customers are people that schedule often. Someone who needs to set up calendars for clients or events.
