A site designed to grow while nobody’s watching.

RentFormulas serves small US landlords with seven interactive calculators and software-comparison pages — every page generated from verified vendor pricing and statute-cited law datasets covering all 51 US jurisdictions. The brief we set ourselves was blunt: build it to run untouched. Publishing, indexing and reporting are all automated.

It runs today at autopilot-venture.vercel.app while rentformulas.com completes its move — the name is pending, the autopilot is not.

What we designed & built

The growth loop is the product.

Most content sites decay the day their author gets busy. This one ships its own next twenty pages every week.

01

Calculators that answer

Seven interactive tools for the questions landlords actually type — grounded in datasets with statute citations, not blog-post folklore.

02

Comparison, verified

Software-comparison pages built from verified vendor pricing data — regenerated, not rotting.

03

A real SEO surface

Dynamic sitemap, JSON-LD, IndexNow pings, a cookieless analytics beacon and an affiliate redirect rail — all built from scratch.

The tech

Under the hood.

An autopilot needs two things: a growth loop and locks on the cockpit door.

01

The weekly loop

A Vercel cron promotes 20 queued page specs, warms them through ISR, pings IndexNow, and files its own growth report — publish → index → report, hands-free.

02

Security model

Supabase anon access is read-plus-telemetry only; admin functions are token-gated security-definers with sha256-hashed tokens — automation with least privilege.

03

51 jurisdictions, cited

The law datasets carry statute citations across every US state plus DC — the unglamorous accuracy work that makes the calculators defensible.

On the work · Viva Grafix, 2026

RentFormulas is our thesis on programmatic SEO done honestly: verified data, cited statutes, and a growth loop that runs itself — a publishing machine engineered to deserve the traffic it compounds.
