Hooklistener is a modern tool designed for developers to test, inspect, and debug webhooks and HTTP requests efficiently.

While many webhook tools offer temporary disposable URLs, Hooklistener focuses on a professional workflow with persistence and collaboration at its core. It serves as a comprehensive middleware to visualize incoming data from services like Stripe, PayPal, Shopify, or your own APIs.

Key Features:

  • Real-time Inspection: Instantly view headers, body payloads (JSON, XML, Form), and query parameters in a clean, structured UI.
  • Team Collaboration: Unlike most alternatives, Hooklistener allows you to invite team members to shared workspaces so you can debug integrations together in real-time.
  • Request Replay: Easily retry failed webhooks or forward captured requests to your local development environment (localhost) for testing.
  • Permanent History: Your request logs are saved, allowing you to search and review past payloads without fearing they will disappear after closing the tab.
  • Granular Control: Filter and search through requests to find exactly what you need.

Hooklistener is the ideal alternative for developers who need more than just a temporary bin and require a reliable tool for building and maintaining API integrations.

socketify.py features and specs

  • High Performance
    Socketify.py is designed for high scalability and performance, leveraging an efficient event loop and native extensions to handle a large number of concurrent connections efficiently.
  • WebSocket Support
    The library provides built-in support for WebSockets, making it suitable for real-time applications where persistent connections between client and server are necessary.
  • Asynchronous I/O
    Socketify.py is built on top of asynchronous I/O paradigms, allowing non-blocking operations that can improve the throughput of networked applications.
  • Ease of Use
    The library offers a clean and straightforward API with examples and documentation, which lowers the barrier to entry for developers who are new to network programming in Python.
  • Python Integration
    Being a Python library, socketify.py integrates well with existing Python applications and can be included as part of larger, multi-component systems.

Possible disadvantages of socketify.py

  • Limited Adoption
    As a relatively new or niche library, socketify.py might have a smaller user base and community compared to more established frameworks like Flask or Django, which could result in fewer community resources and third-party integrations.
  • Learning Curve
    For developers who are accustomed to synchronous programming paradigms, adapting to the asynchronous programming model of socketify.py may require an initial learning investment.
  • Documentation Depth
    While there is documentation, it might not be as extensive or comprehensive as those of more mature libraries, potentially requiring more experimentation or source code reading to fully grasp advanced features.
  • Potential Stability Issues
    Being less established, there might be undiscovered bugs or stability issues in production environments compared to long-standing Python networking libraries.
  • Ecosystem Limitations
    The library might lack some of the extensive third-party plugins or tools available in more popular frameworks, which could limit its extensibility.

Agile SaaS Startups

E-commerce Development Agencies

Fintech Integration Teams

Independent API Developers

What makes your product unique?

Hooklistener's answer

Hooklistener combines real-time webhook inspection with robust team collaboration and monitoring features. Unlike disposable tools, we offer permanent request history, shared workspaces for teams, email testing, and downtime alerts, making it a complete debugging ecosystem rather than just a temporary bin.

Why should a person choose your product over its competitors?

Hooklistener's answer

Choose Hooklistener if you need reliability and teamwork. While competitors offer temporary URLs that delete your data upon closing the tab, Hooklistener provides a persistent workspace where history is saved. Itโ€™s built for professionals who need to replay requests, share debug sessions with colleagues instantly, and monitor their endpoints for silence or errors.

How would you describe the primary audience of your product?

Hooklistener's answer

Our primary audience consists of Backend Developers, QA Engineers, and technical teams building integrations with third-party APIs (like Stripe, Shopify, or PayPal). It is ideal for agile teams that need to debug asynchronous events collaboratively without setting up complex local infrastructure.

What's the story behind your product?

Hooklistener's answer

Hooklistener was born out of frustration. As developers, we were tired of using "disposable" webhook tools that lost critical data whenever we refreshed the page or closed the browser. We needed a tool that treated webhook debugging as a serious part of the development workflowโ€”with persistence, security, and the ability to work together as a team. So, we built it.

Which are the primary technologies used for building your product?

Hooklistener's answer

Hooklistener is built on a modern, high-performance stack utilizing Real-time WebSockets for instant data delivery. We use a scalable cloud infrastructure to ensure data persistence and low-latency processing, ensuring that every webhook is captured and displayed the millisecond it arrives.

  • Show HN: Python framework is faster than Golang Fiber
    These "benchmarks" are useless, they're not testing anything real world except the performance of uWebsockets. There are copy errors all over the place.

  • This is how I started the development of the fastest ASGI and WSGI Server in TechEmPower Benchmarks
    After starting the project called socketify.py at https://github.com/cirospaciari/socketify.py, I got pretty good results and reviews, but many people asked if socketify.py could be used to create a WSGI and ASGI server. WSGI and ASGI have a lot of overhead, that's is why I choose not to use them in the first place, but adding an ASGI and WSGI server allows a lot of code already written to run faster!
