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.

Analysis of socketify.py

  • Ask HN: What are you working on? (June 2026)
    Iโ€™m working on PDFBolt, a PDF generation API for developers. https://pdfbolt.com Itโ€™s for the boring pdf jobs every SaaS eventually gets: invoices, reports, certificates, contracts, labels, that kind of thing. You send html, a url, or a template with JSON data, and get a PDF back. Last week we shipped the Node SDK. Right now Iโ€™m working on the Python SDK and tightening up the docs. - Source: Hacker News / 2 months ago
  • Ask HN: What Are You Working On? (March 2026)
    Working on PDFBolt (https://pdfbolt.com) - a PDF generation API. You send HTML, a URL, or a Handlebars template with JSON data, get a PDF back. Uses Playwright underneath so modern CSS just works. Lately been deep in PDF/X print production - PDF/X-1a and PDF/X-4 with ICC color profiles and CMYK conversion. Had to build 11 color space converters on top of PDFBox 3.0. Also shipped an AI template generator where you... - Source: Hacker News / 5 months ago
  • Ask HN: What Are You Working On? (February 2026)
    Https://pdfbolt.com A PDF generation API, Chrome-based. Most of my time lately goes into print production - browsers render everything in RGB but print needs CMYK with ICC color profiles, and getting that conversion right inside the PDF turned out to be a much deeper problem than expected. Got PDF/X-1a and PDF/X-4 working now. - Source: Hacker News / 6 months ago
  • Open source and self hostable/private file converter
    I can recommend https://pdfbolt.com. It is unfortunately not self-hosted but built with privacy in mind. I'm the founder. - Source: Hacker News / over 1 year ago

  • 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. And then an advertisement: https://github.com/cirospaciari/socketify.py#briefcase-comme... Is this a professional framework that produces proper, real-world benchmarks and... - Source: Hacker News / over 3 years ago
  • 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!
