2026 Jupyter Community Call For Funding Proposals

The Jupyter Executive Council and Jupyter Foundation are pleased to announce a new Call for Proposals (CFP) for funding the Jupyter community. Visit the Jupyter Foundation Community Proposals webpage to learn more about the process and how to submit proposals. The call for proposals is open through Wednesday, September 9, 2026.

The Jupyter Foundation began its operations in early 2025 with a mission to use its resources to support the Jupyter community. As part of this mission, we funded a round of community proposals in 2025. This funded work continues to bring many benefits to the Jupyter ecosystem (see the progress reports here). In this next call for proposals, we are iterating on this success.

The call for proposals is open through Wednesday, September 9, 2026.

Visit the Community Proposals webpage to learn more about past funded proposals and the Jupyter Foundation team compass for more detailed background about this funding call. In this second round, our goal is to continue learning how to best manage a community funding program. Based on feedback, we are updating the proposal process in several ways, including:

• A new section of the proposal template has been added for Jupyter council or committee endorsements. We strongly encourage authors to seek and include endorsements from Jupyter councils or committees affected by the proposal. Each endorsement should be a brief paragraph about the impact of the proposed work from the council or committee’s perspective, and express support for the work and a willingness to receive it. We encourage authors to communicate early with relevant Jupyter councils and committees to make this endorsement process easier.
• The de-risk section of the proposal is now optional for smaller funding requests.
• The CFP is open for several weeks longer than the previous round. We do not anticipate extending the CFP deadline this time.

As with the previous round, to help inspire proposals we are particularly excited to fund, we’ve defined funding priorities for the Jupyter Foundation. These are key outcomes that we must improve in order to grow the overall health and impact of the ecosystem. Briefly summarizing, these priorities are:

• Grow the contributor capacity of Jupyter. We would like to grow the number of contributors, improve the efficiency of existing contributors, and facilitate learning across Jupyter subprojects. We’d love to see proposals that help us mobilize and support the total pool of energy available to contribute to Jupyter. Examples of recent activities in this area include hiring a community manager and hosting community workshops.
• Improve the reliability, security, and consistency of Jupyter’s software and team practices. We believe that our technology will be more impactful and easier to contribute to and deploy if we improve our development infrastructure and team practices in ways that contribute to reliability, security, and consistency. Examples of recent activities in this area include investing in better testing infrastructure and linting rules, refactoring build systems, improving accessibility, funding security issue triage, and hosting a subproject roadmap alignment workshop.

While we’re particularly excited about these two outcomes and aim to focus funding on proposals that clearly feed into one or both of these priorities, we also encourage people to get creative and submit proposals for outcomes that have high impact and strategic value for the Jupyter community. We’re excited to see what others come up with, and are eager to work with you in unlocking critical funding in support of Jupyter’s community.
