DomainBook Pro is built around the economics of a domain book, not just record-keeping. It tracks acquisition cost basis, fees and renewals paid, then computes net profit, ROI and annualized ROI on every sale โ and it pulls live RDAP data so expiration dates are real rather than remembered. Portfolio, renewals, sold and dropped ledgers, health benchmarks, multi-currency reports and Excel exports all live in one workspace, for a flat $20/month with no per-domain fees.
Most brokers are juggling a spreadsheet, a self-hosted tool like DomainMOD, or a marketplace-first platform like Efty. DomainBook Pro is hosted and maintained for you, and it focuses on the decisions that actually cost money: live RDAP expiration tracking with 30/60/90-day surfacing, true cost basis and ROI math, quarterly Hold/Monitor/Review/Drop tiering, and portfolio-health benchmarks. Pricing is flat $20/month for unlimited domains โ it doesn't scale up as your book does.
Domain brokers and investors running anywhere from a few dozen to several thousand names across multiple registrars โ solo flippers, small brokerages and portfolio managers who have outgrown a spreadsheet but don't want to self-host and babysit a heavyweight tool. One login per brokerage, unlimited domains.
DomainBook Pro grew out of the 40-column spreadsheet every domain investor eventually builds โ the one that goes stale the moment a name renews and never tells you your real return. It was built by MacappDevelops LLC as a deliberately focused tool: fast, hosted, one login per brokerage, unlimited domains, and every number a broker actually needs to make a renew-or-drop call. It launched in June 2026.
A dependency-free Node.js backend built entirely on Node's standard library, serving a no-build vanilla-JavaScript single-page app. Live domain data comes from RDAP/WHOIS over raw HTTPS, billing runs on Stripe, and CSV/XLSX exports are generated server-side. Deployed in Docker behind Cloudflare.
