Answers to frequently asked questions.

Is ODK free?

ODK is open-source software. It is free as in "freedom". You will always be able to use and modify it for free.

ODK is not free as in "no cost". ODK requires resources (e.g., phones, servers) to use and it requires resources (e.g., developers, testers) to make.

Using our hosting helps sustain ODK and ensures our community can continue to have global impact.
