Browser-based Professional Demo & 3D Mockup Creator
openvid
Summary: Openvid is an in-browser web application for recording screens or uploading videos, then adding smooth zooms, device mockups, 3D camera movements, and custom backgrounds to export cinematic demos. It runs entirely client-side using FFmpeg.wasm, Three.js, and Canvas API, with no installation required. Supports multi-track timelines, 4K/2K/1080p export in MP4, WebM (with transparency), GIF, and image formats. Data persists locally via IndexedDB and LocalStorage; cloud backup via Supabase is planned.
Description: A browser-based video editor focused on creating professional product demos and 3D mockups. Features include screen recording, video upload (MP4, WebM, MOV, MKV), 100+ pre-designed backgrounds, custom images/gradients/SVG/text overlays, timeline-based zoom/speed/easing controls, 3D camera tilt/rotation, multi-track support, and auto-trim. Rendering pipeline uses FFmpeg.wasm for encoding, MediaBunny for optimized video processing, Three.js for 3D effects, and html-to-image for mockup export. Built with pnpm, TypeScript, and modern web APIs.

A coding-agent skill for multi-phase security audits with independently verified, machine-readable findings - cloudflare/security-audit-skill
This GitHub repository provides a coding-agent skill for conducting structured security audits. It operates through six phases: reconnaissance, coverage-led hunting, candidate validation, structured output, independent record verification, and target-neutral reporting. The system utilizes isolated agents and coverage critic feedback to find security vulnerabilities, ensuring findings are independently verified by agents separate from the discoverers. The skill employs a verdict system using labels such as 'confirmed', 'needs_validation', and 'rejected' based on source trace and observed impact. It supports repeated runs to iteratively improve coverage, with prior analyses used to target gaps and revalidate changed sources. Installation and execution are managed via the Skills CLI, requiring Node.js for validation and an OS-enforced sandbox for target code execution. The skill is noted as the initial prototype that seeded Cloudflare's broader vulnerability discovery harness.
