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)

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.
Open Source Advantage: AGPL v3 License
Sigma Exacta is proudly released under the GNU Affero General Public License v3 (AGPL v3), one of the strongest open source licenses available. This license guarantees complete freedom to use, study, modify, and distribute the software for any purpose while ensuring all modifications and derivative works remain open source. Our commitment to transparency extends to network use rights, ensuring even users interacting with the software over a network receive source code access.
Our open source philosophy extends beyond code to embrace open data and open innovation. By making algorithms, methodologies, and implementation details publicly accessible, we accelerate innovation through community contributions, ensure transparency by allowing engineers to verify calculations, promote education worldwide, build trust through complete visibility, and foster industry-wide best practices.
