Show HN: OS Yamato – A gentle digital OS inspired by wabi-sabi

4 months ago 1

OS Yamato 🌸

A gentle operating system where data blooms, fades, and returns to the wind. Even the quietest message can carry the weight of a season.

⸻

✨ Now Open

After two and a half months of quiet, steady growth, OS Yamato has opened its gates to the world. This isn’t just software — it’s a philosophy of impermanence, care, and simplicity.

⸻

🌿 Philosophy

We believe digital memories, like real ones, shouldn’t last forever by default. OS Yamato invites you to experience a mindful, seasonal digital space: • No hoarding. • No clutter. • Just meaningful moments.

Notes, photos, and messages gently fade if left untouched — and disappear after a year.

⸻

🖼️ How It Works • Each data object (note, photo, contact…) includes a lastOpenedAt timestamp. • After 330 days unopened, it shows a 🥀 icon as a sign of wilting. • After 365 days, it is automatically deleted — returning to the wind.

⸻

🌸 Features • Diary — Entries bloom and fade like flowers. • Chat — Seasonal animations turn conversations into gentle encounters. • Memo & Contacts — Designed to wilt without revisiting. • Photos & Videos — Live 365 days unless you return. • Wind Messages — Letters that arrive months later, like whispers on the breeze. • Clock & Games — Time visualized poetically.

⸻

⚙️ Tech Stack • 🖥️ Frontend: Vue 3 + Vite • ☁️ Backend: AWS Amplify (Cognito, AppSync, DynamoDB, S3) • 🧠 Lifecycle Control: TTL-based expiration with visual feedback • 🌍 Hosting: Amplify Hosting + Global CDN • 💡 Design Ethos: Inspired by impermanence and wabi-sabi
