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 $10 a month — 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.
Two dozen analysis and planning modules, sharing one consistent interface, one project file, and one-click Excel export.
Scope, goals, team and timeline in one page.
Map suppliers, inputs, process, outputs, customers.
Structure root-cause analysis by category.
Translate needs into measurable CTQs.

Proper Cpk/Ppk, ANOVA-based Gage R&R, and real hypothesis tests — not spreadsheet approximations.
Send any analysis — results and charts — to a clean, shareable workbook in one click.
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.
Plan and scope any project for free. Unlock the full statistical toolkit and Excel export with Pro — with a 5-day free trial.
Your process data stays private on every plan — including the free one.
Yes. All analysis runs locally in your browser — your datasets are never uploaded to us, and we keep no cloud copy of your studies. Your account and billing are handled securely by our auth and payments providers, but your actual process data stays on your machine.
You get the core capability, measurement-system, hypothesis, DOE and SPC analysis a Six Sigma project needs — in any browser, with nothing to install and no license server. It's built for practitioners who want professional rigor without enterprise pricing or IT overhead.
If you don't continue with Pro, your account simply drops to the Free plan — you keep the planning tools and never get locked out of your work. Your saved project files are yours regardless of plan.
No. Shuriken Stats runs entirely in a modern web browser on Windows, macOS, or Linux. Open the page and start working.
Yes. You can cancel from your account at any time; you'll keep Pro access through the period you've paid for, then move to the Free plan.
Run a full DMAIC project — from charter to capability study — with tools that respect your time and your data.
