Hello Product Hunt community! 👋
I’m Ziyang, the creator of Yu-Ni OS. Super excited to share my passion project with you all today!
When exploring modern AI web applications, I noticed a common challenge: it’s hard to balance high-performance interaction logic with premium, high-fidelity UI design. Many developers have great AI models but lack a stunning interface to present them.
That’s why I built Yu-Ni OS. It’s a lightweight, high-performance frontend framework designed specifically for modern web AI social platforms.
What makes it special?
🍏 Apple-Like Aesthetics: Deeply integrated frosted-glass micro-animations that give your AI chat a premium, native-app feel.
🚀 Rock-Solid Architecture: Features a progressive three-tier fallback link architecture to handle complex interactions (long press, dynamic debounce, multi-state conflicts) without breaking.
🛠️ 100% Open Source: Highly encapsulated into modular components, making it incredibly easy to connect with any LLM API.
We have an exciting roadmap ahead for Q3 and Q4, including expanding the responsive interaction component library and optimizing our global state core algorithms.
Since it's fully open-source under the MIT license, I would absolutely love to get your honest feedback, feature requests, or bug reports!

I'll be here all day to answer any questions. Thank you so much for your support! 🚀

how does the three-tier fallback architecture actually handle rate limits from providers like openai when traffic spikes hard

@perihan7176 When traffic surges, the three-tier architecture handles rate limits by: Tier 1 (primary model) uses token buckets and predictive throttling — switching traffic away before hitting limits, never relying on 429 responses. Tier 2 (backup models) rotates multiple API keys with instant cooldown on failure. Tier 3 (local fallback) serves cached replies, templates, or queues requests for later. Degradation is gradual, not all at once, and paid users always stay on Tier 1.

The frosted-glass aesthetic really comes through in the UI mockups, love how the blur layers feel intentional rather than overdone. Curious how the three-tier degradation actually performs under real traffic.

@turkbayyig96068 The deliberate imperfection of frosted glass — visible contours, hidden details — embodies restraint in UI design. For the three-tier architecture under real traffic, the degradation ratio tells the story: below 10% spillover, users notice nothing; above 30%, backup model quality drops become apparent. The most common failure isn't the architecture itself, but "recovery avalanche" — when Tier 1 comes back online, all queued requests flood in and knock it down again. Recovery must be gradual, releasing only a fraction of traffic per second until stability is confirmed.
