Summer of Haskell
GSoC 2025 Ideas
This is a list of ideas for contributors who are considering to apply to Google Summer of Code 2025 for Haskell.org
For project maintainers
Are you working on a Haskell project and you could use the help of a contributor during the summer? Consider adding it as an idea here! You can contribute ideas by sending a pull request to our github repository (example from 2024). If you just want to discuss a possible idea, please contact us.
What is a good idea? Anything that improves the Haskell ecosystem is valid. The GSoC rules state that it must involve writing code primarily (as opposed to docs).
Projects should be concrete and small enough in scope such that they can be finished by the contributor. Past experience has shown that keeping projects “small” is almost always a good idea.
Important changes since 2021/2022: In the past, GSoC projects were expected to take up the equivalent of full time employment for a student. In 2021, this was reduced to half time positions: students were expected to work around 175 hours in a 10 week period. Since 2022, contributors now have the choice between a larger (around 350 hours) or a smaller project. Ideas should indicate in which category they fall.
Projects should benefit as many people as possible – e.g. an improvement to GHC will benefit more people than an update to a specific library or tool, but both are acceptable. New libraries and applications written in Haskell, rather than improvements to existing ones, are also welcome.
For students/contributors
We have added some tips on writing a proposal here. Please be aware that:
- This is not an all-inclusive list, so you can apply for projects not in this list and we will try our best to match you with a mentor.
- You can apply for up to two ideas (but only one can be accepted).
