BlobCalc – Interactive math dashboards encoded entirely in the URL

Summary: BlobCalc creates interactive, shareable math dashboards with all logic and UI encoded in the URL hash, eliminating servers, accounts, and tracking. It instantly generates slider-based interfaces from formulas, enabling private, portable calculators that run fully in the browser.

What it does

BlobCalc compresses formulas, variables, and UI settings into the URL using LZ-string encoding, producing stateless calculators that require no backend or database. Users write formulas to generate interactive dashboards that can be shared as live links anyone can adjust.

Who it's for

It is designed for users needing transparent, portable math tools such as ROI models, budgeting, and engineering calculations without relying on spreadsheets or server-based apps.

Why it matters

BlobCalc solves privacy and portability issues by keeping all data client-side and enabling instant sharing of adjustable calculators without tracking or backend dependencies.
