Made on the factory floor.
FactoKit is a toolkit for manufacturing, built by someone who works in production and systems integration, for the engineers who do the same work: production and quality engineers, integrators, automation specialists and programmers.
Why FactoKit
The small jobs of a production day tend to end up scattered across browser tabs, spreadsheets and scripts: a capability check, a byte order, a takt calculation, a message to validate. Each one is simple, until it has to be right.
- 01Check the numbers
Capacity, cycle times, capability and production losses.
- 02Connect the systems
Payloads, protocols and data conversions.
- 03Get back to work
Focused tools. Clear inputs. Useful results.
Principles
- 01
Calculations run in your browser
There is no server doing the maths. The pages are static files and every result is computed on your own device.
- 02
Your data is not sent anywhere
What you paste or open stays in the page. There are no accounts, no analytics and no cookies. The contact form below is the one exception, and it sends only what you type into it.
- 03
Works offline
Each tool also comes as a single HTML file you can save and open without a connection, and the site can be installed as an app.
- 04
Checked against independent references
Results are compared with calculations written separately and with worked examples from the literature, not with the tool’s own code.
- 05
Free
No registration and no paywall. The libraries and fonts used, and their licenses, are listed on the Licenses page.
How the calculations are checked
- The method is written down. Each tool has a Method section with its formulas, defaults and limits, and says where it follows a convention that differs between programs.
- A second implementation. The results are compared with reference calculations written separately, in Python with libraries such as SciPy and statsmodels or in exact fractions, and with published worked examples.
- Tests run on every change. Those reference values are part of the automated tests, together with browser tests of the pages and of the offline files.
- What is not verified says so. Tables and rules written from memory or not yet compared with their source are marked unverified on the page, in the exports and in print. They are never presented as final.
FactoKit is a working tool, not a validated or certified system. For regulated or safety-critical decisions, check the results yourself.
