Tepuy Solutions

The embeddable widget suite

9 live free-standing, AU-specific financial widgets, plus 24 more in preview below — mortgage, stamp duty, LMI, CGT, super caps and more — each built on an already-verified Tepuy calculator engine, not a generic formula. Every widget accepts ?theme=light|dark, ?accent=#hex, ?firmName= and ?cta= query params for embedding — free to use, free to embed on your own site, no account required.

These twenty-four are built and embeddable. The loan widgets share one amortisation engine reconciled against every other repayment calculation on the site; the savings widgets share a savings engine checked against it; the income widgets share one tax engine whose every rate is quoted from the legislation. They are not indexed yet — they join the list above at their go-live round.
