Devlog - Day 4

Final Log Before Ship

VasuOS v1.0.0 is ready

After around 5 days of working on this project and about 5 hours of coding, VasuOS is finally done.

I found MeowOS while looking through Stardance projects and wondered how a website could look this good. Then I found the WebOS 1 beginner mission and decided to try it myself.

Today, 27-08-2026, I finished VasuOS.

Features

• File system
• Terminal with an Easter egg
• Google Search
• File/Image Viewer with multiple windows
• Credits page

My frontend-designer friend also said it looks good, so I’m calling that a win.

This is just VasuOS v1.0.0.
