When will sprints take place?
Monday, May 18th, 2026, 8:00am – Tuesday, May 19th, 2025, 9:00pm PST - Sprints are free to attend with a PyCon US registration.
NOTE: Please be familiar with the PyCon US Health & Safety Guidelines. Sprint days are part of the conference and only registered attendees of PyCon US can participate due to the guidelines put in place for the 2026 conference.
Development sprints are a key part of PyCon US, and a chance for the contributors to open-source projects to get together face-to-face for two days of intensive learning, development and camaraderie. Newbies sit with gurus, go out for lunch and dinner together, and have a great time while advancing their project.
Why not join the sprints this year at PyCon US? by Naomi Ceder
What's a sprint?
PyCon US Development Sprints are two days of intensive learning and development on an open source project of your choice, in a team environment. It's a time to come together with colleagues, old and new, to share what you've learned and apply it to an open source project.
In the crucible of a sprint room, teaming with both focus and humor, it's a time to test, fix bugs, add new features, and improve documentation. And it's a time to network, make friends, and build relationships that go beyond the conference.
PyCon US provides the space and infrastructure (network, power, tables & chairs); you bring your skills, humanity, and brainpower (oh! and don't forget your computer).
Who can participate?
You! All experience levels are welcome; sprints are a great opportunity to get connected with, and start contributing to your favorite Python project. Participation in the sprints is free and included in your conference registration. If you are attending sprints, please go to your attendee profile on your dashboard and indicate the number of sprint days you will be attending.
Who can run a sprint?
You! If you've never run a sprint before, the In-Person Event Handbook is an excellent guide.
Instructions for adding a sprint project to this page are below.
What's the schedule?
Sprints run all day from Monday, May 18th through Tuesday, May 19th. That's 8:00am to 9:00pm PST.
Please note: Lunch will not be provided so please plan your lunch breaks accordingly!
Where will the sprints be?
The Sprints will take place at the Long Beach Convention Center. Each Sprinting project will claim its own room or if the room is large enough, it will share the space with other Sprinting Projects.

Python Infrastructure
Come work on the Python infrastructure!
BeeWare
Do you want to write an app for your phone using nothing but Python? Have you got some Python code that you'd like to distribute to users as a standalone installer? BeeWare is a collection of libraries and tools for building a cross-platform native graphical user interface using nothing but Python, and then packaging your Python code as a standalone app for distribution on macOS, Windows, Linux, iOS, Android, or as a single-page web app. No matter your level of experience, we can find a way for you to contribute to BeeWare. And every contributor earns a BeeWare Challenge Coin!
hatch
Hatch is a modern extensible environment manager. We support you in your packaging needs with hatchling a batteries included approach to better defaults for packaging your project. We will work on adding new things to hatch, fixing annoying bugs to improve the experience. All skill levels are welcome! We will be holding a sprint on the 18th.
Marcus
Marcus is an open-source orchestration server for AI coding agents. You describe what to build. Marcus breaks the work into tasks on a shared kanban board. Multiple agents pull tasks independently, write the code, and coordinate through the board — never through chat. You walk away; you come back to working software.
Tiny Hub Energy
My project is a DePIN (Decentralized Physical Infrastructure Network) software running on Google Cloud. The IaaS software also features an invisible back end network with plans to batch settlements via Pimlico every 5 minutes. In my opinion, society as a whole will refuse to adapt to anything boasting crypto, we all know it can be a little sketchy. Given all the advancements in AI, a DePIN product can finally have all the automation required and predictive functions needed for major success. Additionally, there is an opportunity here to become the first closed loop cloud software, our cloud compute cost could instantly be replaced with clean energy coming from out customers. Smart home devices and bidirectionally charged EVs are set to create the first real "smart homes" and I envision this orchestrated in real time on the tiny hub network. Microgrid strategies for small communities across the country and a grid upgrade are required to continue to scale this technology. Maybe one day my platform can shoot type 1 energy beams from a space based solar farm straight to a residential home, anything is possible.
Django
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It's been around for 20 years and is built to take care of much of the hassle of web development, so people can focus on writing apps without needing to reinvent the wheel. If you'd like to get started before sprints begin, you can make sure your machine can run the tests locally Newcomer friendly!
PyOpenSci
pyOpenSci supports the Python scientific software ecosystem through its open community-led peer reviews and free Python packaging resources. It also has its own software that requires maintenance. We will work on documentation, infrastructure, security, translations, and other tasks. Ideas for new features are welcome too! This is our fourth year hosting sprints at PyCon US. Read the recap of our 2024 sprint to get an idea what to expect: https://www.pyopensci.org/blog/recap-pyos-pyconus-2024.html#-our-second-pyopensci-sprint- Whether you are an experienced Python developer or just getting started, everyone is welcome!

aio-libs: aiohttp and the ecosystem
- The aio-libs organization maintains a suite of foundational asyncio libraries for Python, including aiohttp, a widely used HTTP client/server library. These libraries form the async backbone of many production systems and open source projects.
- We’ll be sprinting on open issues across aiohttp and its dependencies, including bug fixes, documentation improvements, test enhancements, and broader ecosystem support. All experience levels are welcome. We’re happy to help new contributors get set up and find a task that matches their interests.
- Please review our planned sprint board for ideas — it’s a starting point, not a limit. If you have something else you’d like to work on within aiohttp or the wider aio-libs ecosystem, bring it along and we’ll help you scope it.
- Before contributing, please take a look at our Code of Conduct and the contributing guide, which covers setting up a development environment, running the test suite, and our PR workflow.
-
Pre-download before you arrive. Sprint Wi-Fi gets overloaded fast. Please clone the repo and install the development dependencies ahead of time so you’re ready to code on day one:
git clone --recurse-submodules https://github.com/aio-libs/aiohttp.git; cd aiohttp; make install - Maintainer @bdraco will be at the sprint in person. Other maintainers, including @webknjaz (@webknjaz:matrix.org), will be available in #aio-libs:matrix.org during the sprints; come say hi or chat with us there.
- We are in Seaside ballroom A, third table back on the left side of the room, first row.
- Note this sprint is only running Monday May 18th due to scheduling conflicts.
