As answered by people managing NetAPI and ClientForms.app.
ClientForms.app's answer:
Frontend: Next.js 15 (React 19), Tailwind CSS Backend: Supabase (PostgreSQL, Row-Level Security) Authentication: Clerk Payments: Stripe Hosting: Vercel (Sydney region) Database hosting: Supabase (Australian data residency)
NetAPI's answer
Security and threat intelligence teams (newly registered and compromised domains), brand protection and anti-phishing services, sales and marketing teams building lead lists, SEO and web analytics companies, and researchers who need complete lists of registered domains.
ClientForms.app's answer:
Psychologists who assess ADHD and autism. Typically private practice, solo or small group (1-5 clinicians), currently using paper forms and spending hours on admin per assessment. They want something that works and is secure.
NetAPI's answer
Every zone in one subscription: 380M+ active domains in 1,500+ TLDs, newly registered domains every day, enriched datasets and lists by DNS provider and registrar. We also publish free datasets: the daily NetAPI Top 1M websites ranking and compromised domain and IP lists (CC BY 4.0).
ClientForms.app's answer:
Neurodivergent-first design. Most digital forms just replicate paper online. ClientForms is built specifically for ADHD and autism patients - progress bars with time remaining (helps with time blindness), softer colours instead of harsh white, sticky headers so you always know where you are. The forms are designed to reduce anxiety and improve completion rates.
NetAPI's answer
Plain CSV files and a simple API, every TLD in one plan from $49 a month, daily updates, and a founder who has worked with domain data since zonefiles.io.
ClientForms.app's answer:
Most clinical software treats patients as an afterthought. ClientForms is designed specifically for neurodivergent users who are filling out the forms, progress indicators, time estimates, calmer colours, predictable layouts. One link, no signup required, works on any device. Patients just open and complete.
NetAPI's answer
NetAPI was founded by Slava Olesik, who earlier founded zonefiles.io (he sold it in 2017; its later owners shut it down in August 2025). NetAPI is his current project in the same field: domain lists and datasets for 1,500+ TLDs, a simple API and free open datasets. It is run by CodeRockers LTD, Cyprus.
