Quantum-Flow

Hi everyone!

I’m a 15-year-old developer and I’m tired of the "tutorial hell." I’ve decided to form a market anomaly: Building and launching real SaaS products before summer starts.

I’m skipping heavy frameworks and over-engineering. My stack? Pure HTML, CSS, and vanilla JavaScript. No React, no Next.js—just speed and raw code.

Day 1: Quantum-Flow I built this because I needed a lightweight way to stress-test my APIs without the bloat of Postman or complex CLI tools.

• What it does: Stress-tests any endpoint with multiple concurrent requests.

• Tech highlight: Uses IndexedDB for 100% local persistence. Your data never leaves your browser.

• Features: Real-time pulse charts, request comparison (Archive), and a "Stress" mode with live error tracking.

• Note: The tool is currently in Beta. Features are limited as I’m focusing on core stability. It will be unlocked in Summer, with a real deadline in the web app.

It’s simple, it’s fast, and it’s live.

I’d love to get some feedback from this community. Does the "stress" UI feel intuitive? Can you find any bugs in the persistence?

I'll be posting a new SaaS every day. Follow along if you want to see if I make it to Day 30 or if I burn out trying!
