About Springly

In a world where everything costs money, we’re here to create a practical, free tool that modernizes the way we design and select springs.

Traditional spring selectors rely on isolated textbook equations or demand a tedious, manual trial-and-error process. Springly flips the script: you input the physical constraints and functional requirements of your assembly, and our engineering engine mathematically identifies the best off-the-shelf catalog springs for your application.

Our Partnerships

We partner with industry-leading manufacturers to ensure the catalog data driving our engine is accurate, comprehensive, and ready for procurement.
