Hi Product Hunt! 👋
I’m 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: “It’s 2026. Why can’t we have high-end engineering math directly in the browser?”
So, I built SigmaExacta. It’s a comprehensive suite of 20+ specialized tools designed for Quality, Reliability, and Industrial Engineers.
What makes it different?
Zero Install: It’s 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: It’s 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.
I’d 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! 🛠️📈
