About Sigma Exacta: Free Open Source Engineering Platform PWA Available
Democratizing Access to Professional Engineering Tools
Sigma Exacta is an open source platform specifically designed for product innovation, development and quality control. Our mission is to democratize access to professional-grade engineering software, making high-quality tools available to engineers, students, and professionals worldwide without cost barriers or vendor lock-in. The project has been developed as a public good, and all the software and educational content will be freely accessible and openly licensed.
Installable Progressive Web App (PWA)
Sigma Exacta is now available as a full-featured Progressive Web App (PWA) that you can install directly on your desktop or mobile device. This provides a native app-like experience with enhanced functionality:

Mobile: Use "Add to Home Screen" from your browser's menu
Benefits: The PWA maintains all the privacy and local-first advantages of our web platform while providing additional convenience and accessibility.
Privacy-First Engineering Software
Sigma Exacta operates on a local-first architecture where all calculations run directly in your browser. This innovative approach ensures your sensitive industrial data never leaves your device, providing maximum privacy and security. Experience zero latency with instant results, maintain complete control over your information, and benefit from open standards that prevent vendor lock-in while ensuring long-term accessibility.
Licensing
Sigma Exacta is available under a dual licensing model:
🔓 Open Source — GNU AGPL v3
Free to use, modify, and distribute under the GNU Affero General Public License v3. Any deployment of a modified version over a network must include source code access for users. Ideal for personal use, academic projects, and other open-source software.
💼 Commercial License
For organizations that need to integrate Sigma Exacta into proprietary products, distribute modified versions as closed-source software, or offer it as a SaaS service without AGPL obligations — a commercial license is available.
Licenses are negotiated individually based on use case, deployment scale, and organization size.
