ReadyStack Tools

Vanilla JS, HTML, CSS. Static hosting on Cloudflare. Python for the build pipeline. Deliberately no frameworks — the tools have to load fast and still work years from now.

A growing set of single-purpose browser calculators — loan amortization, HELOC, refinance — that run entirely client-side. No server, no account, nothing leaves your tab.

Feedback on the calculators, bug reports, or a request for a tool that does not exist yet. If you keep rebuilding the same spreadsheet every month, tell me and I will make it a page.
