Purpose-built for Continuous Improvement. Run capability studies, Gage R&R, hypothesis tests, DOE and control charts with genuine statistical rigor — and plan the whole DMAIC project around them. Nothing to install, and your process data never leaves your machine.
Generic stats packages make you bend a DMAIC project into their world. Enterprise quality suites cost thousands per seat and a ticket to IT. Shuriken Stats speaks the language Continuous Improvement practitioners already use — the tools, the workflow, and the metrics.
Every module maps to a phase — capability, MSA, SPC, DOE — and produces the outputs a belt actually reports. No translating your project into someone else's tool.
Pro is $60 for your first year — not a four-figure annual license with seat negotiations and an IT install. Open a browser and get to work.
Charters, SIPOCs, fishbones and Pareto sit right beside the statistics, so a single tool carries you across the entire improvement project.
Every calculation runs locally, right inside your browser. We never upload, store, or even see your process data — there's no cloud database of your studies and no exposure of proprietary measurements. It's analysis that respects an NDA.
More than thirty analysis and planning modules, organized the way you work — Define, Measure, Analyze, Improve, Control — sharing one interface, one project file, and one project notepad.

Runs in any modern browser on any OS. No license servers, no IT ticket, no desktop install.
Professional-grade analysis without the enterprise price tag of legacy desktop software.
