We want to congratulate all of the students who took part in this year’s 10th anniversary of Google Code-in. Great job!





Today we are excited to announce the Grand Prize Winners, Runners Up, and Finalists with each organization.





The 58 Grand Prize Winners completed an impressive 2,158 tasks while also helping other students.





Each of the Grand Prize Winners will be awarded a four-day trip to Google’s campus in northern California to meet with Google engineers, one of the mentors they worked with during the contest, and enjoy some fun in California with the other winners. We look forward to seeing these winners in a few months!

Our 794 mentors, the heart and soul of GCI, are the reason the contest thrives. Mentors volunteer their time to help these bright students become open source contributors. They spend hundreds of hours during their holiday breaks answering questions, reviewing submitted tasks, and welcoming the students to their communities. GCI would not be possible without their dedication, patience and tireless efforts.



We will post more numbers from GCI 2019 here on the Google Open Source Blog over the next few weeks, so please stay tuned.



Congratulations to our Grand Prize Winners, Runners Up, Finalists, and all of the students who spent the last couple of months learning about, and contributing to, open source. We hope they will continue their journey in open source!
