ClientForms.app VS Gottrix.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)

Gottrix.app's answer:

Astro and TypeScript for the site itself, Tailwind CSS for styling, and WebAssembly for the actual conversion engines (ffmpeg.wasm for audio/video, pdf.js and pdf-lib for PDF, libheif and Squoosh for images), all running inside sandboxed Web Workers with zero network access.

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.

Gottrix.app's answer:

Anyone handling files they'd rather not hand to a third-party server: freelancers and professionals working with contracts, invoices or client documents, students and privacy-conscious individuals doing everyday conversions, and international users thanks to 25+ language support. Also a good fit for regulated or confidential business contexts where uploading a file anywhere isn't an option.

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.

Gottrix.app's answer:

Every conversion runs 100% client-side in WebAssembly - files never touch a server, provably so (you can verify it yourself in DevTools' Network panel, or just try it in airplane mode after the first visit). Most converters ask you to trust a privacy policy; gottrix lets you check. On top of that: 500+ tools across PDF, image, audio, video, data and 3D formats in one place, no account, no signup, available in 25+ languages.

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.

Gottrix.app's answer:

Competitors like Smallpdf, iLovePDF, Convertio and CloudConvert upload your file to their servers to process it - fine for a random image, risky for a contract, medical record, or anything confidential. gottrix never uploads anything, so there's nothing to leak, no server log of what you converted, and no need to trust a third party with sensitive documents. It's also free without the usual catches: no per-file limits, no watermarks, no forced account, and it keeps working offline once loaded.

Gottrix.app's answer:

gottrix started from a simple frustration: nearly every "free" online file converter requires uploading your document to someone else's server, even for something as routine as compressing a PDF or converting a photo. gottrix was built to remove that requirement entirely. Everything runs in the browser via WebAssembly, so the file never leaves the device in the first place.
