A Minitab-like alternative for everyday QE work
SpcLite is not affiliated with Minitab®. It aims at the same quality-engineer habits — worksheets, session output, SPC/MSA/DOE — in a local-first browser app.
Open SpcLiteWhen SpcLite is enough
- You need control charts, capability, Gage R&R, and common tests on a shared or personal browser
- Data must not leave the plant network or laptop
- You want a PWA you can install without a desktop license negotiation
- Six Sigma project work centers on MSA · SPC · DOE rather than every niche procedure
Honest gaps vs a full desktop suite
- Not every specialized Minitab procedure is implemented (e.g. some GLM / advanced modeling paths)
- No server-side collaboration or shared project database yet
- Output formatting follows SpcLite session blocks — useful, but not a pixel clone of every Minitab report
- Numeric validation targets scipy/NIST references; plant-standard Minitab golden tables are still recommended before regulated sign-off
At a glance
| Aspect | SpcLite | Desktop suite |
|---|---|---|
| Where it runs | Browser / PWA | Desktop install |
| Data location | Local IndexedDB (no upload) | Local files / IT-managed |
| License model | Use in the browser | Per-seat desktop license |
| QE core (SPC/MSA/DOE) | Strong everyday coverage | Broad, mature suite |
| Offline | Yes (after first load) | Yes |
