As answered by people managing Datavisual.app and Cert Decoder.
Datavisual.app's answer
DataViz was born out of frustration with how complicated data visualization tools had become. Most tools require expensive licenses, steep learning curves, or coding knowledge. We wanted to build something anyone could use — upload a file, get a beautiful chart, done. We added AI to make it even easier: just describe what you want in plain English. Built by LibLab, DataViz is free and open source because we believe data visualization should be accessible to everyone.
Cert Decoder's answer:
I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.
Datavisual.app's answer
The frontend is built with React, TypeScript, Vite, and TailwindCSS, using Apache ECharts for rendering 30+ chart types. AI features are powered by Google Gemini. The backend runs on Python with FastAPI, SQLAlchemy, and a Supabase PostgreSQL database. The app is hosted on Vercel with PWA support for offline use. Payments are handled through Lemon Squeezy.
Cert Decoder's answer:
certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server
Datavisual.app's answer
Students and researchers who need to visualize project data quickly. Data analysts who want beautiful charts without Excel's limitations. Developers looking for a free, open-source charting tool. Small teams and freelancers who can't justify enterprise BI subscriptions. Essentially, anyone who has a spreadsheet and needs a chart — fast.
Cert Decoder's answer:
certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.
Datavisual.app's answer
Unlike Tableau or Power BI, DataViz requires no installation, no subscription, and no learning curve. You upload a CSV, pick a chart (or let AI pick for you), and you're done in seconds. It's browser-based, works on any device, and supports dark mode, PWA offline access, and 4 languages. For users who need quick, beautiful visualizations without enterprise complexity, DataViz is the fastest path from data to chart.
Cert Decoder's answer:
Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

DataViz Platform combines 30+ interactive chart types with AI-powered chart generation in a single free tool.

Unlike most competitors, all core features — including dashboards, exports, and multi-language support — are completely free with no trial limits or paywalls.

Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
