Introduction to GSoC 2026 and Rust's Participation
Google Summer of Code (GSoC) has become a cornerstone for nurturing new contributors in open source, and the Rust Project is once again an active participant in this global program organized by Google. After announcing a list of project ideas earlier this year, the Rust community began engaging with potential applicants on their official Zulip chat platform. These early discussions proved fruitful, with several applicants already making meaningful contributions to various Rust repositories before the official start of the program.
From Ideas to Proposals
The project ideas covered a wide range of areas within the Rust ecosystem, from language tooling to embedded development. After weeks of collaboration and refinement, applicants submitted their formal proposals by the end of March. This year saw a remarkable surge in interest: the Rust Project received 96 proposals—a 50% increase over the previous year. While the team was pleased by the enthusiasm, they also noted the emergence of AI-generated proposals and low-quality contributions generated by automated agents. However, these challenges remained manageable and did not overshadow the genuine interest from aspiring open-source developers.
Selection Challenges and Criteria
With such a high volume of proposals, the Rust Project's mentors faced a difficult task. As a large and diverse organization, Rust has many priorities, and the selection process had to balance multiple factors. Each proposal was evaluated based on:
- The applicant's prior interactions with the Rust community
- Their existing contributions to Rust repositories
- The quality and clarity of the proposal itself
- The potential impact of the proposed project for Rust and its wider community
Mentor Availability and Funding Constraints
Additionally, mentors' bandwidth and availability played a critical role. The Rust Project had to cancel some planned projects because several mentors lost their funding for Rust-related work in recent weeks. This unfortunate development forced the team to prioritize projects that could be realistically supported with the remaining mentor pool.
The Final Selection
As is customary in GSoC, even when a project topic received multiple proposals, only one could be chosen per topic. The team also had to avoid assigning multiple projects to a single mentor, to prevent overloading. After a careful narrowing process, the Rust Project submitted an ordered list of the most viable proposals to Google. On April 30, Google announced the accepted projects, and the Rust community celebrated a significant milestone: 13 Rust Project proposals were accepted—a substantial number that reflects the program's growth and the community's dedication.
The Accepted Projects
Below you'll find the first six of the 13 accepted proposals, listed alphabetically. (The full list of 13 is available on the Rust Project's official blog.)

Looking Ahead
The Rust Project is thrilled to welcome these 13 new contributors through GSoC 2026. The program runs over several months, during which mentors and participants will collaborate closely to bring these projects to life. For the wider Rust community, these contributions promise to enhance tooling, documentation, and core language features. The Rust Project extends its gratitude to all applicants, mentors, and Google for making this possible. If you're interested in following the progress of these projects, keep an eye on the Rust Zulip and project repositories—the journey is just beginning.
