Turn math into shareable logic. No database, just URL.
Verify all critical math. Results provided as-is.
BlobCalc is a stateless math playground designed for inventors, engineers, and creators. It allows you to wrap complex equations into a clean, interactive UI with sliders and real-time outputs.
Unlike traditional tools, BlobCalc has no backend. It uses LZ-String compression to encode your variables and formulas directly into the URL fragment. When you share a link, you're sharing the entire app state.
Your data never leaves your browser. Because there is no database, your sensitive calculations remain private to whoever has the link. Perfect for quick internal tools and ROI calculators.
1. Define Variables
Add parameters like 'cost' or 'margin'. Set ranges to create interactive sliders.
2. Write Formula
Use standard math syntax. Supports functions like sqrt(), sin(), and log().
3. Deploy
Click 'Share' to generate a 'Field Link'—a clean, dashboard-only view for your audience.
4. Persist
