Capabilities

What Frostflow does

Swarm Engine

32 parallel connections with AIMD adaptive buffer scaling. Downloads at wire speed on gigabit connections.

Video Extraction

Download from YouTube, Instagram, TikTok, Twitter, and 1000+ sites via yt-dlp with quality selection.

Website Scanner

Deep-scan any webpage to find all downloadable resources — images, videos, audio, documents, archives.

Site Crawler

Recursively discover every page on a website with configurable depth, then scan selected pages for resources.

HTML Analyzer

Paste raw HTML to find hidden media, detect DRM, CAPTCHA, obfuscation, and fingerprinting.

Professional CLI

13 commands with rich progress bars, JSON output mode, exit codes, and scripting hooks.

REST API

8 HTTP endpoints for remote download dispatch. Queue downloads from any device or automation pipeline.

cURL Import

Paste any cURL command from browser DevTools. Headers, cookies, and auth tokens parsed automatically.

Request Inspector

Probe any URL to see HTTP headers, redirect chains, SSL info, range support, content details.

Post-Download Hooks

Run shell commands on completed files with pattern matching and variable substitution.

Compression

Compress videos (H.265/H.264 via ffmpeg) and images (WebP/JPEG via Pillow) to save disk space.

Subtitle & Audio

Download subtitles in any language. Extract audio as MP3 from any video source.

Pause & Resume

Pause downloads and resume later — even after app restart. Chunk-level state in SQLite.

Download Scheduling

Schedule downloads for specific times. Bandwidth scheduling for off-peak hours.

Cookie Extraction

Extract browser cookies via Chrome DevTools Protocol. Bypasses App-Bound Encryption on Chrome v127+.

Light/Dark Mode

Full light and dark theme with Ludicrous Mode that disables animations for max performance.
