Sponsor D2
D2 is fiscally sponsored by The Hack Foundation, the 501(c)(3) nonprofit behind Hack Club. Donations made without receiving goods or services are tax-deductible in the United States.
Where the money goes
Thank you to our donors for supporting D2.
D2 is free and open source.
Donations support:
- Keeping d2lang.com, the Playground, icons, and other public tools online.
- Maintaining build, package, and distribution infrastructure.
- Paying contributors for approved project work.
- Supporting open-source projects that D2 depends on.
Fund usage is transparent. D2 was created by Anmol Sethi and me at Terrastruct. In August 2026, I donated D2 to Hack Club so it could continue as an independent nonprofit project. I still lead development, but neither Anmol nor I will receive money from the fund.
Donations are subject to Hack Club's 7% fiscal-sponsorship fee, which includes payment processing.
How the fund works
The D2 fund is public: you can see its balance and every transaction. Hack Club handles the fund and nonprofit administration.
Sponsoring D2 does not affect its roadmap, governance, or license. D2 remains open source under the Mozilla Public License 2.0, and development happens in public on GitHub.
Companies
If your company uses D2, it can donate through the same fund. Want to make a larger donation or contribute infrastructure or services? Email me at alex@d2lang.com.
