Google Summer of Code 2024 accepted contributors announced!


We are celebrating our 20th anniversary of Google Summer of Code (GSoC) and we are thrilled to announce the new 1,220 Contributors that will be writing code for 195 open source mentoring organizations starting May 27. Over the last few weeks, our mentoring organizations have read through applications, had discussions with applicants, and made the difficult decision of selecting the GSoC Contributors they will be mentoring this summer.

Highlighting significant results from this year’s application period:

    • 43,984 applicants from 172 countries
    • 9,107 proposals submitted by 6,518 applicants
    • 1,220 GSoC contributors accepted from 73 countries
    • Over 2,800 mentors and organization administrators
    • 34 mentoring organizations are participating in their 16th-20th GSoC!

Starting today, our GSoC 2024 Contributors will actively engage with their new open source community and become familiar with their organizations during the Community Bonding period. Mentors will guide the GSoC Contributors through documentation and introduce them to community norms and processes while helping plan their milestones and projects for the summer. Coding begins May 27th and while most folks will wrap up September 2nd, GSoC Contributors have the opportunity to request a longer coding period and wrap up their projects between early September and early November based on their schedules and availability.

We’d like to express our gratitude to the thousands of applicants who took the time and effort to reach out to our mentoring organizations and submit proposals this year. The experience of researching, asking questions and becoming more familiar with open source communities has hopefully helped you feel excited about open source and maybe you found a great community that you want to contribute to outside of Google Summer of Code! Communication is key to GSoC and open source, and staying connected with the community or reaching out to other organizations is an exceptional way to set the stage for future opportunities. Open source communities are always looking for new and eager collaborators to join their projects.

A huge thank you to all of our mentors and organization administrators who make this program so special and impactful for thousands of developers each year. Google Summer of Code continues because of the dedication of mentors to keep the open source ecosystem thriving by supporting new developers and their exciting perspectives and ideas. Google is honored to support the open source ecosystem (and 1,000+ open source projects and 20,000+ developers) over these past 20 years.

GSoC Contributors — have fun this summer, keep learning and enjoy becoming part of the open source community! Your mentors and community members have dozens, and in some cases hundreds, of years of combined experience so let them share their knowledge with you to help you become phenomenal open source contributors.

Google Summer of Code 2024 Mentor Organization Applications Now Open

We are excited to announce that open source projects and organizations can now apply to participate as mentor organizations in the 2024 Google Summer of Code (GSoC) program. Applications for organizations will close on February 6, 2024 at 18:00 UTC.

We are celebrating a big milestone as we head into our 20th year of Google Summer of Code this year! In 2024 we are adding a third project size option which you can read more about in our announcement blog post.

Does your open source project want to learn more about becoming a mentor organization? Visit the program site and read the mentor guide to learn what it means to be a mentor organization and how to prepare your community (hint: have plenty of excited, dedicated mentors and well thought out project ideas!).

We welcome all types of organizations and are very eager to involve first-time mentor orgs in GSoC. We encourage new organizations to get a referral from experienced organizations that think they would be a good fit to participate in GSoC.

The open source projects that participate in GSoC as mentor organizations span many fields including those doing interesting work in AI/ML, security, cloud, development tools, science, medicine, data, media, and more! Projects can range from being relatively new (about 2 years old) to well established projects that started over 20 years ago. We welcome open source projects big, small, and everything in between.

This year we are looking to bring more open source projects in the AI/ML field into GSoC 2024. If your project is in the artificial intelligence or machine learning fields please chat with your community and see if you would be interested in applying to GSoC 2024.

One thing to remember is that open source projects wishing to apply need to have a solid community; the goal of GSoC is to bring new contributors into established and welcoming communities. While you don’t have to have 50+ community members, the project also can’t have as few as three people.

You can apply to be a mentor organization for GSoC starting today on the program site. The deadline to apply is February 6, 2024 at 18:00 UTC. We will publicly announce the organizations chosen for GSoC 2024 on February 21st.

Please visit the program site for more information on how to apply and review the detailed timeline for important deadlines.

Google Summer of Code 2023 Final Results!

On November 17th, we wrapped up our 2023 Google Summer of Code program where 903 contributors completed open source projects for 168 OSS organizations. This year 70% (628) of the successful 2023 contributors opted for a 12-week project, while the remaining 30% (275) completed their GSoC work over the past few weeks. That being said, many contributors choose to continue involvement in the OSS community after finishing their GSoC projects. GSoC is typically just one small chapter in a contributor's lifetime open source journey.

This certainly was one of our most enthusiastic groups of mentors & GSoC contributors yet. We were able to host multiple virtual check-ins where contributors had the chance to ask GSoC Administrators questions and get live reminders and advice regarding the program and its milestones, the response to these sessions was overwhelming with one session having over 60% of 2023 GSoC contributors attending. Our final virtual event as part of this series was a multi-day ‘Contributor Talks’ Series where 43 participants had the chance to give three minute Lightning Talks about their GSoC projects.

Quick GSOC 2023 by the Numbers: 99% of 2023 orgs say that GSoC has value for their organization, 83% of 2023 contributors said they would consider being a mentor, 30% of 2023 contributors said that GSoC has already helped them with a job offer, 99.8% of 2023 contributors plan to continue working on open source, 88%
of 2023 contributors were first-time GSoC contributors meaning 12% had participated in GSOC before, 96.25% of contributors said they would apply to GSoC again.
In 2023, GSoC contributors rated their GSOC experience as 3.79/4. Mentors gave their GSoC contributor's overall performance a 4.41/5.

Our mentors and GSoC contributors spent a lot of time giving us invaluable feedback from the program so we wanted to share a few top insights below. Their comments help us to keep the program relevant and to continue to meet the needs of open source communities and new open source contributors.


Advice for future contributors

As we head into our 20th year of GSoC, we wanted to highlight some of the advice that the 2023 GSoC contributors offered to future contributors. Much of the advice falls into the themes of:

    • Communicate early and often with mentors.
    • Take the time in February as soon as orgs are announced to find the right org and choose a project you are excited about, it will make the program much more enjoyable.
    • Set realistic goals and break tasks into milestones.
    • Be open to learning! Open source can seem intimidating but you have amazing mentors and the community there encouraging and supporting you.

We welcomed 18 new mentoring organizations this year, many of which were able to attend our Mentor Summit on Google’s campus a few weeks ago.

In 2023, 10.15% of GSoC contributors were non-students. This was the second year since we opened up the program to non-students. We hope to continue to have more potential GSoC contributors who are changing careers or not currently enrolled in academic programs join the program.

“My advice is to just go for it. I'm a thirty-something career-changer who doesn't have a technical background; at times, I doubt myself and my ability to transition into a more technical field. During GSoC, I was paired with knowledgeable, friendly, engaging mentors who trusted me to get the work done. It was empowering, and I did work that I'm extremely proud of. To anyone in my shoes who may be afraid to take the plunge, I highly encourage them to do so. Seriously - if I can do it, anyone can."
      – brittneyjuliet, GSoC’23 Contributor

Favorite part of GSoC

GSoC contributors have shared their favorite parts of GSoC with some very common themes:

    • Working on real-world projects that thousands/millions of people actually use and rely on
    • Interacting with experienced developers and truly being part of an enthusiastic, welcoming community
    • Making a difference
    • Gaining overall skills and confidence to boost their careers that can’t be obtained from classrooms alone

How GSoC improved their programming skills

95.5% of contributors believe GSoC improved their programming skills. The most common responses to how GSoC improved their skills were:

    • Practical experience. Applying programming concepts and techniques to real projects.
    • Learning to write cleaner, more maintainable code.
    • Enhanced problem solving skills.
    • Project management - learned how to break large, complex problems into smaller, organized tasks.
    • Learning to understand complex codebases.
    • Learning new concepts and technologies.
    • Engaging in code reviews with mentors regularly helped to grasp industry best practices.

We want to thank all of our mentors, organization administrators, and GSoC contributors for a rewarding and smooth GSoC 2023. The excitement from our GSoC contributors throughout the program and our mentors at the recent Mentor Summit was palpable. Thank you all for the time and energy you put in to make open source communities stronger and sustainable.


GSoC 2024 will be open for organization applications from January 22–February 6, 2024. We will announce the 2024 accepted GSoC organizations February 21 on the program site: g.co/gsoc. GSoC contributor applications will be open March 18–April 2, 2024.

Google Summer of Code 2024 Celebrating our 20th Year!

Google Summer of Code (GSoC) will be celebrating its 20th anniversary with our upcoming 2024 program. Over the past 19 years we have welcomed over 19,000 new contributors to open source through the program under the guidance of 19,000+ mentors from over 800 open source organizations in a wide range of fields.

We are honored and thrilled to keep GSoC’s mission of bringing new contributors into open source communities alive for 20 years. Open source communities thrive when they have new contributors with fresh, exciting ideas and the renewed energy they bring to these communities. Mentorship is a vital way to keep these new contributors coming into the open source ecosystem where they can see collaboration at its finest from their community members all across the world, all with different backgrounds and skills working towards a common goal.

With just over a week left in the 2023 program, we have had one of our most enthusiastic groups of GSoC contributors with 841 GSoC contributors completing their projects with 159 open source organizations. There are 68 GSoC contributors wrapping up their projects. A GSoC 2023 wrap up blog post will be coming late this month with stats and quotes from our contributors and mentors.

Our contributors and mentors have given us invaluable feedback and we are making one adjustment around project time commitment/project scope. For the 2024 program, there will be three options for project scope: medium at ~175 hours, large at ~350 hours and a new size: small at ~90 hours. The idea is to remove the barrier of available time that many potential contributors have and open the program to people who want to learn about open source development but can’t dedicate all or even half of their summer to the program.

As a reminder, GSoC 2024 is open to students and to beginners in open source software development that are over the age of 18 at time of registration.

GSoC 2023: project results and feedback part 1



In 2023, Google Summer of Code brought 966 new contributors into open source software development to work with open source organizations on a 12+ week project. We had 168 participating open source organizations with mentors and contributors from over 75 countries this year.

For 19 years, Google Summer of Code has thrived due to the enthusiasm of our open source communities and the 19k+ volunteer mentors that spend from 50-150 hours mentoring each of our 20k contributors since 2005! This year, there are 168 mentoring organizations and over 1,950 mentors participating in the 2023 program. A sincere thank you to our mentors and organization administrators for guiding and supporting our contributors this year. We are also looking forward to hosting many of the 2023 GSoC Mentors on campus this fall for the annual Mentor Summit.

September 4th concluded the standard 12-week project timeline and we are pleased to announce that 628 contributors have successfully completed this year’s program as of today, September 5th, 2023. Congratulations to all the contributors and mentors that have wrapped up their summer coding projects!

2023 has shown us that GSoC continues to grow in popularity with students and developers 19 years after the program began. GSoC had a record high 5,679 contributor applicants from 106 countries submit their project proposals this year. We also had huge interest in the program with over 43,765 registrants from 160 countries applying to the program during the two week application period.

The final step of every GSoC program is to hear back from mentors and contributors on their experiences through evaluations. This helps GSoC Admins continuously improve the program and gives us a chance to see the impact the program has on so many individuals! Some notable results and comments from the standard 12-week project length evaluations are below:

  • 95.63% of contributors think that GSoC helped their programming skills
  • 99.06% of contributors would recommend their GSoC mentors
  • 97.81% of contributors will continue working with their GSoC organization
  • 99.84% of contributors plan to continue working on open source
  • 82.81% of contributors said they would consider being a mentor
  • 96.25% of contributors said they would apply to GSoC again

Here’s some of what our GSoC 2023 Contributors had to say about the program!


At the suggestion of last year’s contributors, we added multiple live talks throughout the coding period to bring contributors together, providing tips to help them make the most of their GSoC experience. Each of these talks were attended on average by 42% of the 2023 GSoC contributors.

Another request from our previous contributors was to hear more about the cool projects their colleagues did over the summer and the opportunity to talk about their own projects with others. Over the coming weeks we are hosting three lightning talk sessions where over 40 of the 2023 contributors will have the opportunity to present their project learnings to the other contributors and their mentors.

We’ll be back in a couple of months to give a final update on the GSoC projects that will conclude later this year. Almost 30% of contributors (286 contributors) are still completing their projects, so please stay tuned for their results in part two of this blog post later this year!

Google Summer of Code 2023 accepted contributors announced!

We are pleased to announce the Google Summer of Code (GSoC) Contributors for 2023. Over the last few weeks, our 171 mentoring organizations have read through applications, had discussions with applicants, and made the difficult decision of selecting the GSoC Contributors they will be mentoring this summer.

Some notable results from this year’s application period:
  • 43,765 applicants from 160 countries
  • 7,723 proposals submitted
  • 967 GSoC contributors accepted from 65 countries
  • Over 2,400 mentors and organization administrators

Over the next few weeks, our GSoC 2023 Contributors will be actively engaging with their new open source community and getting acclimated with their organization. Mentors will guide the GSoC Contributors through the documentation and processes used by the community, as well as help with planning their milestones and projects for the summer. This Community Bonding period helps familiarize the GSoC Contributors with the languages and tools they will need to successfully complete their projects. Coding begins May 29th and most folks will wrap up September 5th, however, for the second year in a row, GSoC Contributors can request a longer coding period and wrap up their projects by mid-November instead.

We’d like to express our appreciation to the thousands of applicants who took the time to reach out to our mentoring organizations and submit proposals. Through the experience of asking questions, researching, and writing your proposals we hope you all learned more about open source and maybe even found a community you want to contribute to outside of Google Summer of Code! We always say that communication is key, and staying connected with the community or reaching out to other organizations is a great way to set the stage for future opportunities. Open source communities are always looking for new and eager collaborators to bring fresh ideas to the table. We hope you connect with an open source community or even start your own open source project!

There are a handful of program changes to this 19th year of GSoC and we are excited to see how our GSoC Contributors and mentoring organizations take advantage of these adjustments. A big thank you to all of our mentors and organization administrators who make this program so special.

GSoC Contributors—have fun this summer and keep learning! Your mentors and community members have dozens, and in some cases hundreds, of years of combined experience. Let them share their knowledge with you and help you become awesome open source contributors!

Mentor organization applications are open for Google Summer of Code 2023!


We are excited to announce that open source projects and organizations can now apply to participate as mentor organizations in the 2023 Google Summer of Code (GSoC) program. Applications for organizations will close on February 7, 2023 at 18:00 UTC.

As 2023 begins, so does our 19th year of Google Summer of Code! Last year, we had a few updates to the program that will continue for the 2023 program year. Our most noted change coming in 2023 is that we are expanding the program to be open to students and to beginners in open source software development. We are also continuing our increased flexibility in the length of the projects—offering 175 and 350-hour projects—and the ability to extend the program from the standard 12 weeks up to 22 weeks.

Does your open source project want to learn more about becoming a mentor organization? Visit the program site and read the mentor guide to learn what it means to be a mentor organization and how to prepare your community (hint: have plenty of excited, dedicated mentors and well thought out project ideas!).

We welcome all types of organizations and are very eager to involve first-timers with a 2023 goal of welcoming 30+ new orgs into GSoC. We encourage new organizations to get a referral from experienced organizations that think they would be a good fit to participate in GSoC.

The open source projects that participate in GSoC as mentor organizations do all kinds of interesting work in security, cloud, development tools, science, medicine, data, media, and more! Projects can range from being relatively new (about 2 years old) to well established projects that started over 20 years ago. We welcome open source projects big, small, and everything in between.

One thing to remember is that open source projects wishing to apply need to have a solid community; the goal of GSoC is to bring new contributors into established and welcoming communities. While you don’t have to have 50+ community members, the project also can’t have as few as three people.

You can apply to be a mentor organization for GSoC starting today on the program site. The deadline to apply is February 7, 2023 at 18:00 UTC. We will publicly announce the organizations chosen for GSoC 2023 on February 22nd.

Please visit the program site for more information on how to apply and review the detailed timeline for important deadlines. We also encourage you to check out the Mentor Guide, our new ‘Intro to Google Summer of Code’ video, and our short video on why open source projects are excited to be a part of the GSoC program.

Good luck to all open source mentor organization applicants!
