At roughly $0.50 per student, a school of 1,000 students pays in the region of $500 a year for paid graphing software. With KiwiGrapher that cost is zero, for the same NCEA graphs.

How we keep this comparison fair
We think you should compare tools on facts, not marketing. So a few things we want to be upfront about:
- NZGrapher is a respected tool. It has supported New Zealand statistics teachers for many years, and plenty of great teaching has been done with it.
- The figures here may change. Pricing and feature details for NZGrapher are taken from publicly available information and should be re-checked against the official NZGrapher site before you rely on them.
- We're independent. KiwiGrapher is not affiliated with, or endorsed by, NZGrapher.
If you spot anything in this comparison that's inaccurate or out of date, we want to fix it.
Switching questions
Is KiwiGrapher really free, with no catch?
Yes. KiwiGrapher is free for students, teachers and schools, with no per-student fees and no login. See pricing for how that's sustained.
Will my students lose features if we switch?
KiwiGrapher covers the NCEA graph types and inference tools most classes use: dot plots and box & whisker, histograms, scatter with regression, time series, bootstrap confidence intervals and re-randomisation. Try your usual tasks in the app to check it fits your teaching.
Is student data safe?
KiwiGrapher runs entirely in the browser, so data stays on the student's device and is never uploaded. That's often simpler for school privacy requirements. See For Schools.
Do we need to install or set anything up?
No. Open app.kiwigrapher.com in any modern browser and start. There's nothing to install or configure.
