Challenge Overview
The PyWeb Creators hackathon challenges developers to build web applications using Python EVERYWHERE—whether that's Python-only frameworks or Python running directly in browsers.
On August 1st, we celebrate World Wide Web Day—commemorating Tim Berners-Lee's invention that democratized information sharing. This year, we're proving that Python can power the ENTIRE web stack!
The Mission
Choose your path and show the world that Python belongs everywhere on the web!
Traditional web development requires juggling HTML, CSS, JavaScript, and backend languages. But what if Python could do it all?
This hackathon celebrates two revolutionary approaches: frameworks that generate everything solely from Python code, and technologies that run Python directly in browsers.
Two Paths, One Goal:
Python-Powered Web
Expertly combine both approaches! Use FastHTML for the backend and PyScript for complex client-side tasks. Or try Streamlit with Pyodide components. Get creative!
Hybrid Approach
Build complete web apps where you write primarily Python code. The framework handles HTML/CSS/JS generation for you.
Python-Only Frameworks (Server-Side)
Path A:
Run Python directly in the browser using PyScript, Brython, or similar technologies. Perfect for zero-server applications!
Python-in-Browser
(Client-Side)
(Client-Side)
Path B:
Note: This is not an exhaustive list! If you know other Python web libraries or tools, you're welcome to use them. We encourage exploration and innovation!
- PyScript — Run Python in browser
- Brython — Python client-side implementation
- Pyodide — CPython compiled to WebAssembly
- Skulpt — Python implementation in JavaScript
- Transcrypt — Python to JavaScript compiler
Python-in-Browser Technologies
Path B:
- FastHTML — Modern framework with HTMX
- Reflex — Full-stack framework compiling to React
- Streamlit — Data apps with automatic reactive UI
- Gradio — ML/data science-focused interfaces
- NiceGUI — Native-feeling web apps
- Flet — Flutter-based Python framework

Hybrid Guidelines
Document which parts use which approach
Aim for Python in both frontend and backend
Aim for Python in both frontend and backend
Path B → Guidelines
Python must run IN THE BROWSER
No server-side dependencies for core functionality
Minimal JS for library initialization is acceptable
Should work offline when possible
No server-side dependencies for core functionality
Minimal JS for library initialization is acceptable
Should work offline when possible
Use Python-focused web frameworks
Server-side Python is encouraged
Let the framework handle web complexities
Server-side Python is encouraged
Let the framework handle web complexities
Path A → Guidelines
- 80%+ Python Logic: The majority of your application logic should be in Python
- Minimal Manual Web Languages: Avoid writing raw HTML/CSS/JS where possible (framework-generated is fine)
- Open Source: Use OSI-approved licenses
- 72-Hour Creation: Build during the hackathon window
Core Requirements
Technical Guidelines
Beautiful is better than ugly — Explicit is better than implicit — Simple is better than complex — Complex is better than complicated — Flat is better than nested — Sparse is better than dense — Readability counts — Special cases aren't special enough to break the rules — Although practicality beats purity — Errors should never pass silently — Unless explicitly silenced — In the face of ambiguity, refuse the temptation to guess — There should be one obvious way to do it — Although that way may not be obvious at first unless you're Dutch — Now is better than never — Although never is often better than right now — If the implementation is hard to explain, it's a bad idea — If the implementation is easy to explain, it may be a good idea — Namespaces are one honking great idea, let's do more of those
Remember: These are just suggestions. Build whatever excites you!
5
Creative CodingBuild generative art, music applications, or interactive visualizations. Show Python’s creative side!
4
Data Science StudiosCombine server frameworks with client-side Python for powerful data analysis tools that respect privacy.
3
Educational PlatformsInteractive lessons, code playgrounds, or quiz systems. Perfect for summer learning projects!
2
Real-Time DashboardsUse FastHTML’s reactivity or Streamlit’s auto-updates to build live dashboards. Financial trackers, monitoring systems, or analytics platforms.
1
Offline-First ApplicationsBuild PWAs that work completely offline using PyScript or Brython. Create note-taking apps, calculators, or games that never need a server.
These are just examples to inspire you—we accept all types of web applications!
