Webhook Scheduler

Schedule webhooks for later, cancel them when users act first, and inspect every delivery attempt — without maintaining cron jobs or queues.

php eventloop

a simple non blocking and async event loop written in php

Not present

Webhook Scheduler is an API and dashboard for one-off delayed HTTPS requests. Schedule a callback with a URL, payload, headers, and run time; cancel it with one API call if the underlying state changes. Failed deliveries use automatic retries, while every attempt records its status code, latency, response preview, and timeline.

It is designed for cancelable trial reminders, payment follow-ups, delayed onboarding, and background API callbacks. Test a real delivery without an account, then start free with 100 jobs per month.

Webhook Scheduler features and specs

Cancel Before Dispatch
Cancel a pending job with one API call when a customer upgrades, pays, or completes the expected action first.
One-Off Delayed Webhooks
Schedule a public HTTPS request for a future timestamp with its method, payload, and optional headers.
Automatic Recovery
Retry transient delivery failures with exponential backoff and plan-based recovery attempts.
Delivery Evidence
Inspect status code, latency, response preview, and retry timeline for every delivery attempt.
API and Dashboard
Create, inspect, cancel, and retry jobs through the API while support teams use the operational dashboard.
HTTPS and SSRF Protection
Accept public HTTPS targets only and reject localhost, private networks, and unsafe destinations.
Signed Deliveries
Verify webhook authenticity using HMAC-SHA256 delivery signatures.

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 Webhook Scheduler

Overall verdict

Webhook Scheduler appears to be a niche tool aimed at developers and automation-focused teams who need to trigger webhooks on a schedule; without independent reviews or extensive track record, it seems like a functional, purpose-built utility rather than a widely established platform, so it's worth trying via a free tier or trial before committing.

Why this product is good

Focused specifically on scheduling and triggering webhooks, which simplifies automation without needing to build custom cron jobs or backend logic
Likely offers a straightforward interface for setting up recurring or timed HTTP requests, reducing developer overhead
Can integrate with existing workflows and third-party services that accept webhook calls
May provide logging or monitoring of webhook delivery status, aiding in debugging automation issues
Probably has a lower learning curve compared to building a full automation platform from scratch

Recommended for

Developers who need a simple way to schedule outgoing webhook calls without managing infrastructure
Small teams building automation pipelines that rely on time-based triggers
No-code/low-code users who want to connect scheduled events to APIs or services that support webhooks
Startups looking for a lightweight, specialized tool rather than a full-featured workflow automation suite like Zapier or Make
Users who already have webhook endpoints set up and just need reliable scheduling on top

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
