Istanbul, Turkey – May 2–4, 2025
Registration
Welcome to the Wikimedia Hackathon 2025 event registration!
The Wikimedia Hackathon is organized by the Wikimedia Foundation in collaboration with Wikimedia User Group Turkey (WMTR) and is taking place in-person in Istanbul, Turkey, from May 2nd to May 4th, 2025 at the Renaissance Polat Istanbul Hotel.
Registration will be open until mid April 2025 or until we reach event capacity. Each person that attends the Hackathon is required to register. A discounted room rate link, for those that are self-funded and want to stay at the hotel venue, is listed below. Registration is now closed - we are at capacity!
Check if your passport is up to date and if you will need a visa (or an e-visa) to travel to Turkey; citizens of most countries can apply for an e-visa online.
The Hackathon is primarily an on-site, in-person event. Those people who cannot attend the Hackathon in-person will be able to follow some of the program content online, but should not register with this form. More information will be provided closer to the event on how to participate remotely.
The Hackathon event is free for all to attend. Catering (lunch, dinner, snacks, and drinks) will be provided during the event and covid-related equipment will also be available upon request (e.g. self test kits and masks). Participants are expected to book their own travel arrangements and accommodation to attend the event.

Engage in Conversations
The following channels are designed for connecting with fellow participants. While some may be more or less active throughout the year, they offer valuable opportunities for discussions and networking.
- Wikimedia Hackathon Telegram group
- Libera Chat IRC chat channel: #wikimedia-hackathon connect (the IRC and Telegram channels are bridged together so you only need to be in one)
- Event talk page
- The hashtag
#wmhackon Mastodon, Twitter/X, and other social media.
Existing projects to hack on
- Mobile contributions to Wikimedia Commons: Taking pictures for Wikipedia is one of the simplest ways of contributing. We have a fantastic team of volunteer developers from all over the world working on the Wikimedia Commons mobile android app. A lot of work still remains to improve code quality, add some of the most requested new features and promote the app among potential users. We need a team with a very diverse set of skills to keep making this app better.
- Community Wishlist 2023: The Community Wishlist Survey is an annual survey allowing Wikimedia project contributors to propose and vote for tools and platform improvements. These ideas reflect the challenges Wikimedia communities, projects, and organizations face. You can choose a proposal from the 2023 survey results (suggested "hackathonable" tasks have been marked in the table). Some of these wishes promoted during a recent Community Wishathon, remain valid and are ideal for Hackathon newcomers, particularly those from the local community seeking beginner-level projects.
- Developer wishlist 2017: The Developer Wishlist Survey was conducted in 2017 to address the challenges faced by the MediaWiki developers and Wikimedia's technical community related but not limited to, the MediaWiki core software, APIs, developer environment, data dumps, server infrastructure, contribution processes, and documentation. There are still many technical wishes remaining from this list; you can choose one from this workboard on Phabricator or view a list of all the results.
- Wikidata project ideas: They are around building games, tools for editing, developing interactive tours and tutorials, and more. These projects are small-sized, easy to begin, and can be completed during the Hackathon.
- Projects emerging from the Developer track of Wiki Workshop 2023, supported by Wikimedia Research community members.
- Browse the projects proposed on Phabricator left over from the 2023 Hackathon in Athens.
- Browse the projects proposed on Phabricator that have been posted for this year's Hackathon.
Additional resources
If you're new-ish to the movement, or just wanting to explore other aspects of coding, check this list of resources to get on board with new or additional technical contributions:
- Wikimedia Developer Portal
- Learn about Phabricator
- Information for new developers
- Basic skills needed to contribute to development of MediaWiki core and MediaWiki extensions
- An overview of the MediaWiki Action API
- The Wikidata Query Service (WDQS) provides a way for tools to access Wikidata data
- Gerrit, the tool to handle code reviews
- Special:MyLanguage/Wikibase
- An introduction to Wikimedia Cloud Services (i.e., Toolforge, PAWS)
- An overview about Structured Data
- A basic overview of the implementation of Lua on Wikimedia projects
Online participation
The Wikimedia Hackathon 2025 is primarily an onsite event, and we couldn't enable full remote participation. However, there are various possibilities for people attending remotely to work on projects and interact with other participants:
Work on tasks: The tasks distribution and tracking takes place on the main work-board on Phabricator. Feel free to indicate that you are working on a task or to ask questions directly to others in Phabricator comments.
Interact with participants: The Hackathon social channels (IRC, Telegram, etc.) will be very active during the event, and the remote attendees are welcome to join these channels, talk about their projects and asks, and ask questions to the many technical contributors who are present on these channels.
Project presentations: The opening session (including project presentations) and the closing showcase will be livestreamed on Mediawiki's Youtube channel. Unfortunately, it will not be possible for remote attendees to participate in these sessions. Remote participants are invited to present their projects on the Hackathon social channels instead.
Program and workshops: The sessions / workshops that happen onsite during the event will not be recorded or broadcasted online. However, notes will be taken on Etherpad documents, and the speakers will share their slides on Wikimedia Commons. If you are particularly interested in a session, feel free to contact the speaker so they can send you more information.
