Use history as context
Explore GSoC organizations and open-source programs without guessing from a single year.
Participation history can show which communities have mentored contributors, what technologies they use, and what kinds of projects have been proposed. It does not guarantee that an organization will return in a future cohort, so use HelpMeHack for research and confirm the active program list with the official source.
Filter by multiple years
Compare repeated participation across years instead of treating one appearance as a long-term signal.
Filter by technologies
Narrow organizations by languages and tools you already know, then inspect their past projects and contribution paths.
Continue beyond programs
A program application is only one way into open source. You can also browse active repositories and contribute directly throughout the year.
Frequently asked questions
Answers about HelpMeHack's GSoC and Summer of Bitcoin program data.
What open-source programs are available on HelpMeHack?
The Programs directory currently covers Google Summer of Code organization history and Summer of Bitcoin cohorts, with participation years, technologies, projects, repositories, and official source links where available.
Can I filter GSoC organizations by technology and year?
Yes. You can select multiple participation years and multiple technologies, then search by organization, topic, or repository to narrow the directory.
Does appearing in a past GSoC year mean an organization will return?
No. Historical participation is useful context, not a prediction. Always check the current official program source for the active year's accepted organizations and application details.
Can I see previous GSoC projects?
Yes, where the source data provides them. Organization pages group historical projects by year and link to project or code pages when those links are available.
GSoC data includes historical participation and project links and is cached for 30 days. Summer of Bitcoin covers every cohort from 2021 through 2026, with official year links and curated repository mappings where available.
