Julia Developer Survey 2025

Dear Participant,

You are invited to participate in the seventh annual Julia User and developer survey. The results of this survey will be
presented at JuliaCon 2025 this summer and will also be made publicly available online. The survey is developed,
administered and analyzed by JuliaHub with input from the Julia community. We value your time and appreciate your
participation. This survey consists of 32 questions and is expected to take no more than 10-15 minutes to complete.

Your participation is voluntary and anonymous and no personal information will ever be shared.

Please feel free to forward to colleagues and friends who are Julia users.

Thank you for your participation!

Sincerely,
Jeff Bezanson, Stefan Karpinski, Viral Shah and Alan Edelman
