Tool Vault
I built a mortgage payment calculator for people who just want clean, fast numbers without the lead-gen friction. https://toolvault.co/tools/mortgage-payment-calculator It started because every time I tried to run mortgage scenarios, I hit one of these problems: Forms that demand email/phone before showing results Slow, ad-heavy pages that feel like landing funnels, not tools Calculators that only show principal + interest, ignoring real monthly costs What this tool does: Calculates full monthly housing cost: principal, interest, property tax, insurance, PMI, and HOA…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.
