Features & Architecture
A native application built entirely on web standards.
Zero-Install Execution
You shouldn't need admin rights to watch a video. Our player exists entirely within a browser tab. By leveraging Service Workers, the application shell caches itself locally on first load, meaning it works offline immediately thereafter.
Technical note: We use standard CacheStorage APIs. No tracking cookies or LocalStorage bloat.
Direct Hardware Decoding
When you pass a file to the browser, it hands it off to your operating system's native media foundation (MediaFoundation on Windows, AVFoundation on macOS). This guarantees hardware-accelerated decoding for supported codecs like H.264 and HEVC, keeping CPU usage near zero.
Subtitle Precision
HTML5 `<track>` elements are notoriously rigid. We implemented a custom rendering layer that parses SRT and VTT files natively via JavaScript, allowing for real-time synchronization offsets, font scaling, and background opacity controls that the native browser UI doesn't allow.
File API Sandbox
Using `URL.createObjectURL(file)` creates a strict, memory-only reference to your local file. It is cryptographically impossible for our site to upload your 10GB MKV file over a standard internet connection without you noticing, let alone our lack of backend infrastructure to receive it.
Privacy guarantee: Disable your Wi-Fi after loading the page. It will still work flawlessly.
