BlobCalc turns formulas into interactive, shareable dashboards. Without servers, accounts, or tracking. 100% Stateless: Logic is encoded in the URL hash. Sharing the link = sending the calculator. Privacy: No database. Math stays in your browser. Instant UI: Write a formula, get slider-based UI instantly. Shareable: Send "living" links anyone can adjust. Ideal for ROI models, budgeting, and engineering math. Stop building spreadsheets. Start building Blobs.






Hello Hunters! I'm the Manic Inventor. 👋
I built BlobCalc to bridge the gap between "black box" calculators and clunky spreadsheets. I wanted a sandbox where the math is transparent, the UI is clean, and sharing is instant.
To keep it 100% private, I dared myself to build this without a backend. Using LZ-string compression, your entire app title, logic, and variables, is packed into the URL hash.
This means:
Zero Database: Your data never touches a server.
Zero Tracking: Portable logic that lives only in the link.
Field-Ready: Send a "View Mode" link that looks like a custom dashboard on any screen.
BlobCalc is the first entry in the "Blob Suite"—a series of stateless tools I'm building for makers who value privacy and portability. I’ll be hanging out here all day to talk about LZ-encoding, the math engine, or the future of the Lab!
🚀 The Calculator Challenge
I’ve configured two "blobs" to show you the range:
☕Salary to Hourly & Savings
📈Project Budget Burn
Can you share a 'Life Hack' formula in the comments? Whether it's for coffee-to-coding ratios, vacation savings, or even just a funny logic puzzle, post your link below and let’s see who has the most creative use case! I'll be here all day to reply and check them out.
