I'm 16 and I built an infinite canvas that needs NO signup and shares workspaces via 5KB JSON files

Hey Dev Community,I wanted to build something that solves two of my biggest annoyances with modern productivity tools (like Notion or Miro): forced signups and data privacy leaks.
, at 16, while managing my studies, I built AstraviX Studio (https://astravix.xyz) — a privacy-first infinite canvas and dynamic notebook ecosystem.The response has been crazy. Without any paid marketing, we hit a 90 Heat Score on Crunchbase recently and are seeing organic users from the US, India, and Europe.Here is why it is technically different from traditional SaaS:1. Zero Friction (No Login / Sign-up)You don't need to give me your email, phone number, or create a password. You open the website, and your interactive workspace is live instantly.2. The JSON Sharing Loop (Pixel-by-Pixel Accuracy)Since there is no centralized database tracking you, I built a decentralized sharing framework.You build your dashboard/notebook.Click Export, and it downloads a tiny ~5KB .json file locally.You can send this tiny file to anyone via WhatsApp, Discord, or Email.The recipient just clicks Import on AstraviX, and boom! The exact notebook replicates pixel-by-pixel instantly.3. 100% Offline-First & PrivateYour data belongs to you. Everything is saved locally in your browser storage. No cloud database means zero server latency and absolute privacy.Why am I sharing this here?I want to scale this from a few visitors to a global community. I'd love for fellow developers and productivity hackers to test it out.Go to astravix.xyz, mess around with the canvas, export a template, and tell me what you think in the comments below! What features should I focus on next?
