OpenAnyDoc VS ClientForms.app

OpenAnyDoc's answer

TypeScript, React 19, Vite and Tailwind CSS v4. Pages are prerendered at build time and hydrated in the browser. CSV: PapaParse with TanStack Virtual for the table. Excel: SheetJS and ExcelJS, plus a formula parser that recalculates after edits. JSON: the browser's own parser with big-integer support. Hosted on Cloudflare as a Worker with static assets; the privacy tests run in headless Chrome over the DevTools protocol.

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)

OpenAnyDoc's answer

People who receive data files and need to open, check or fix them quickly without the right software or without the permission to upload them: finance, operations and support staff handling exports, developers and analysts looking at JSON and CSV, and Arabic-speaking users whose CSV files show broken text in Excel. Also organisations with a no-upload policy for customer data.

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.

OpenAnyDoc's answer

The file never leaves your computer, and you can check it: open your browser's DevTools, Network tab, drop a 50 MB file, and no request appears. The site's security policy forbids any request to another server, and an automated test fails the build if any page tries one. Most online viewers and formatters upload your file first. OpenAnyDoc is also fully bilingual, English and Arabic, with right-to-left layout and Windows-1256 detection for older Arabic files.

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.

OpenAnyDoc's answer

Because it opens and edits the file without uploading it, without an account and without tracking, and still does the real work: CSV with delimiter and encoding detection, search, filter, sort and cell editing on 100,000+ rows; Excel workbooks (xlsx, xls, xlsm, ods) with recalculating formulas, number formats, merged cells and cell styles; JSON with tree, table and text views, a validator that names the line and column of an error, and a repair tool; TXT with encoding and line-ending choices. Everything downloads back in the same format. The code is open source (MIT), so anyone can read how it works or host a copy inside their own network.

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.

OpenAnyDoc's answer

At work I kept seeing colleagues paste customer files into online viewers and formatters that upload them, just to look at a CSV or a workbook. Every one of those tools makes a privacy promise you cannot verify. I built OpenAnyDoc so the promise is enforced by the browser itself: the page is static, the security policy blocks outside requests, and the test suite drives a real browser and fails on any network call or storage write. The first version shipped in October 2026 in English and Arabic, because the Arabic encoding problem in Excel was the most common complaint I heard.
