Onyx

Product Introduction

1. Onyx is a browser-based screen recording tool that captures studio-quality 4K video and stereo audio directly in the browser without requiring cloud uploads, server processing, or user accounts.
2. Its core value lies in eliminating subscription models and privacy risks by enabling users to record, store, and manage high-bitrate video locally, ensuring full ownership and control over their content.

Main Features

1. Onyx captures 4K resolution video at up to 60 FPS using the VP9 codec, delivering professional-grade clarity for detailed screen recordings such as software tutorials, design workflows, or gaming sessions.
2. Stereo audio recording integrates the Web Audio API to capture 48 kHz sample rate sound with noise reduction, ensuring crisp voiceovers or system audio without external software.
3. All recordings are stored locally as WebM files via the browser’s File System Access API, bypassing cloud storage limits and enabling instant access to raw video files for editing or sharing.

Problems Solved

1. Onyx removes the need for costly subscriptions or time-limited trials imposed by cloud-based screen recorders, which often degrade video quality or retain user data.
2. It serves creators, educators, and professionals who require uncompromised 4K recordings for client deliverables, online courses, or product demonstrations without privacy concerns.
3. Typical use cases include recording coding sessions for developer portfolios, capturing high-fidelity gameplay streams, or creating pixel-perfect UI/UX design walkthroughs for remote teams.

Unique Advantages

1. Unlike competitors like Loom or Screencastify, Onyx processes video entirely client-side, ensuring zero data transmission to third-party servers and compliance with strict privacy regulations.
2. The tool leverages modern browser APIs for hardware-accelerated encoding, enabling 4K recording with minimal CPU/GPU usage and no plugins or desktop installations.
3. Competitive advantages include no recording time limits, free permanent access to all features, and immediate file availability in lossless quality for professional editing suites like Adobe Premiere.
