About Cor Stellaris
Cor Stellaris LLC is a software company dedicated to building modern tools for specialized professionals. We serve industries where practitioners have long been underserved by outdated, expensive desktop software — from optical engineering to vision science and beyond.
Our Mission
We believe professional-grade tools should be accessible, affordable, and available from anywhere. Legacy software across many specialized industries is stuck behind expensive perpetual licenses and single-machine installs. We're changing that by building a platform of cloud-native tools — making them accessible to anyone with a browser.
What We Build
We create web, mobile, and desktop applications for specialized professional domains. Our growing portfolio includes:
Engineering Tools
Professional simulation, design, and manufacturing software for engineers.
Education & Certification
Study tools and exam preparation for professional certifications.
More To Come
We're always exploring new domains where modern software can make a difference.
Our Approach
- 1.Cloud-first. No installations, no license keys. Access from any browser, on any device.
- 2.Domain expertise first. We build tools that solve real problems because we understand the science behind them.
- 3.Fair pricing. Subscription models that let you start free and scale as needed — not $5,000 perpetual licenses.
