Hi Product Hunt! ๐
Iโm the creator of SigmaExacta, and I built this because I was tired of the "Engineering Software Tax."
For decades, if you wanted to perform a professional Weibull Analysis, a Monte Carlo Simulation, or a Taguchi DoE, you had two bad options:
Pay $10,000+ for legacy software licenses that feel like they were designed in the 90s.
Struggle with complex Excel templates that break the moment you have a large dataset.
I thought: โItโs 2026. Why canโt we have high-end engineering math directly in the browser?โ
So, I built SigmaExacta. Itโs a comprehensive suite of 20+ specialized tools designed for Quality, Reliability, and Industrial Engineers.
What makes it different?
Zero Install: Itโs all JavaScript. Open a tab and start calculating.
Privacy First: Calculations happen on your machine. Your sensitive industrial data doesn't have to live on a random server.
Full Suite: Itโs not just one tool. It covers everything from Tolerance Stack-up (Monte Carlo) and Taguchi Methods to Life Data Analysis (Weibull) and SPC.
Professional Reports: Export clean, audit-ready charts and results in seconds.
Whether you are working on a ship's propulsion system, an automotive production line, or a new electronics prototype, SigmaExacta is designed to be your "Swiss Army Knife" for data-driven decisions.
Iโd love to hear your feedback! I'm especially interested in hearing from fellow engineers: What other complex calculation is currently giving you headaches in your daily workflow?
I'll be here all day to answer your questions! ๐ ๏ธ๐

20 years working in engineering, and I kept thinking: why don't we have good, free tools for this?
That's why I built SigmaExacta โ a suite of 20 open-source engineering tools (FMEA, TRIZ, Cpk, Taguchi DOE, Weibull, QFD and more), free for everyone, running entirely in your browser with no data sent to any server.
Today I'm taking the next step: SigmaExacta now offers a Dual License.
๐ AGPL v3 โ free and open source, as always ๐ผ Commercial License โ for companies that want to integrate the tools into proprietary products or SaaS platforms without open-source obligations
If your team uses these tools and wants to build something on top of them, let's talk.
