Tools organised by the teams that use them.

Featured tools
What we are building first — shaped by requests from operators like you.
Plan weekly production capacity: define machines and shift patterns, load them with product demand and routings, find bottlenecks and test what-if scenarios. Runs entirely in your browser.
OEE Calculator
Work out overall equipment effectiveness across every machine on the floor — availability, performance and quality for each production run, the losses ranked in minutes, and a machine-by-machine comparison you can print. Type the runs in or import a spreadsheet. Nothing is uploaded.
Manpower Planner
Plan shift coverage, workforce supply, hiring gaps and labour cost per role. Runs entirely in your browser. No installation, no account, no upload.
Build machining quotes with quantity breaks: operations, material, outsourcing, tooling amortization, overhead and margin. Runs entirely in your browser. No installation, no account, no upload.
Analyze capital equipment investments: payback, NPV, IRR, ROI, discounted payback, sensitivity and scenario comparison. Runs entirely in your browser. No installation, no account, no upload.
Calculate the weight and cost of metal and plastic stock from profile dimensions. Runs entirely in your browser. No installation, no account, no upload.
How it works
From choosing a tool to a printed report — five steps, no account at any point.
- 01
Choose a tool
169 tools across 21 departments. Try any Pro tool online first — sample data is already loaded.
- 02
Download one file
A single HTML file. No installer, no dependencies, no account to create.
- 03
Open it in your browser
Double-click it. Chrome, Edge, Firefox or Safari, on Windows, Mac, Linux or a tablet.
- 04
Enter or import your data
Type it in, or download the spreadsheet template, fill it in Excel and import it back.
- 05
Save, print and back up
It autosaves as you work. Print a full report, or export a .json backup you keep yourself.
No account at any point. Nothing you enter is uploaded — the file works the same with your connection switched off.
See it work
Every tool behaves the same way. Four short demonstrations of entering a record, backing your work up, printing a report, and moving data in and out of a spreadsheet.
Everything runs in the file itself. Type a record, and the headline figures and charts recalculate as you go. No account, no upload, no wait.
Your work saves to this browser automatically. Export a .json backup whenever you want a copy to archive or move to another computer — importing it restores everything exactly.
Print Report composes a clean document with the headline figures, charts, tables and your notes. Print it, or save it as a PDF from the print dialog.
Bring existing data in from a spreadsheet. Download the template, fill it in Excel, and import it back. The file is read on your computer — nothing is uploaded.

Root cause analysis: choosing between 5 Whys, fishbone and 8D
When each method is genuinely the right tool, one real problem walked through all three so the difference is concrete, and the discipline that separates problem-solving from completed paperwork.
Takt time, cycle time and lead time: the three numbers people mix up
Three numbers that sound interchangeable and answer completely different questions. Precise definitions, a single worked example carried through all three, and the repeatability test to run before you balance anything.
How to calculate OEE (and why most OEE numbers are wrong)
The three OEE factors worked through end to end with numbers you can check yourself, followed by the four specific mistakes that make an OEE figure wrong while it still looks entirely plausible.
Frequently asked questions
Do I need to install anything?
No. Every tool is a single HTML file that opens directly in Chrome, Edge or Firefox. There is nothing to install and nothing to update through IT.
Where is my data stored?
On your computer. Tools run locally in your browser and save project files to your own disk. CapsuleM8 never receives your operational data.
Do I need an account?
No. You can browse, download free tools and even purchase premium tools without creating an account. Purchases are delivered through a secure email link.
Are purchases subscriptions?
No. Premium tools are one-time purchases. Optional update plans may be offered later, but the file you buy keeps working.
Can my whole team use a tool?
Yes — department and company licences cover multiple users and allow the file to be placed on a shared drive. See the Licensing page for details.
What if I need a tool you don't have?
Use the Request a Tool page. Requests directly shape the roadmap, and custom tool development is available for company-specific processes.
