As answered by people managing Vircadia 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)
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.
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.
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.

Not pre-baked. I work on https://vircadia.com/ -- it has to give every user their own audio mix to account for their 3D position. This means codec costs add up fast. You can't just encode once and stream the same thing to a dozen people. - Source: Hacker News / over 4 years ago
Both, primarily the first. Low latency is definitely a requirement, but no issues with Opus on that account. > I haven't looked into how expensive it is to encode in terms of CPU time, so I assume maybe you're taking about a bottleneck... - Source: Hacker News / over 4 years ago
