What types of products does KUBERSTAR build?

KUBERSTAR builds websites and web apps, SaaS platforms, AI tools and assistants, browser extensions, desktop applications, client portals, automation systems, backend architectures, data pipelines, internal tools, and production-grade infrastructure. We handle the full spectrum - from polished user-facing interfaces to deep backend engineering and DevOps.

Does KUBERSTAR build its own products or only client work?

KUBERSTAR was founded in November 2022. Since launching our own product line in April 2025, we have shipped 16+ digital products - SaaS platforms, AI tools, browser extensions, and desktop apps. This is how we sharpen our craft and prove our engineering capabilities. We also selectively partner with ambitious companies to build their products.

What technologies does KUBERSTAR use?

Our core stack includes TypeScript, Rust, Python, Go, and JavaScript. For frontend we use Next.js, React, Svelte, and TailwindCSS. Backend: Axum (Rust), FastAPI (Python), NestJS, and Express.js. Desktop: Tauri 2 and Electron. DevOps & Infrastructure: Docker, Kubernetes, GitLab CI, Nginx, and Linux. We pick the right tool for each job - strong opinions, loosely held.

What is KUBERSTAR's development process?

We follow four phases: Discover (understand your product, goals, users, and technical landscape), Design (shape the product with architecture, UX, and technical decisions upfront), Build (ship fast with a modern stack and AI-assisted workflow), and Launch (polished, tested, deployed - a real product, ready for users).

YouTube Hide Watched

YouTube's algorithm loves showing you the same videos you've already watched. It clutters your homepage, pollutes search results, and makes your subscription feed a maze of repeated content. YouTube Hide Watched fixes this with a simple approach: it detects the red progress bar on watched videos and hides them from view. No account permissions needed, no data collection, no background processes — just a cleaner YouTube experience that helps you find content you haven't seen yet.

How it Works

Install from Chrome Web Store

One-click install. No account, no sign-up, no permissions beyond the YouTube domain.

Browse YouTube Normally

The extension activates automatically on YouTube pages and starts detecting watched video indicators.

Watched Videos Disappear

Videos with progress bars are automatically hidden from your homepage, search results, and subscription feeds.

Features

Automatic Detection

Detects watched videos by their red progress bar indicator. No need to manually mark videos — if YouTube shows it as watched, it gets hidden.

Homepage Cleanup

Removes watched videos from your YouTube homepage so every recommendation is something new you haven't seen.

Search & Subscriptions

Works across search results and subscription feeds too. Find unwatched content faster regardless of where you're browsing.

One-Click Toggle

Enable or disable hiding with a single click on the extension icon. Instantly show all videos when you want to rewatch something.

Zero Footprint

No account permissions, no data collection, no background processes. Uses only CSS injection and DOM observation for minimal resource usage.

Use Cases

Declutter Your Feed

Stop seeing the same recommended videos you've already watched. Every tile on your homepage becomes a new discovery.

Find New Content Faster

Scan subscription feeds without scrolling past dozens of watched videos to find the ones you haven't seen yet.

Research Without Noise

When searching for tutorials or reference videos, filter out ones you've already gone through to find fresh perspectives.

Who it's For

YouTube power users, content enthusiasts, and anyone frustrated by YouTube's tendency to resurface already-watched videos in recommendations and search results.
