FetchV

Active

Overview

FetchV is a browser extension designed for downloading HLS (m3u8) videos, live streams, blob videos, and static web media like MP4 and WEBM, converting them into single MP4 files. It targets users needing to save streaming videos from websites, particularly for batch downloads or long offline viewing, but performs best on uncomplicated, non-protected content.¹³⁴

Key Features

HLS Video Support - Downloads streaming videos indexed by m3u8 files and merges fragments into a single MP4 file.
HLS Live Streaming - Captures and saves live HLS streams.
Blob Video Recording - Records buffered data from blob prefix videos when direct media address detection fails.
Multi-thread Downloading - Uses concurrent threads to accelerate download speeds for large files.
Resolution Switching - Allows selection among multiple resolutions provided in HLS m3u8 files.
Media Preview - Displays thumbnails or short previews to identify target media on a page.
Download Progress Tracking - Shows speed, progress, thread control, resolution changes, and filename editing during downloads.
Static Media Support - Handles MP4, WEBM, and other playable web videos or audios.

Alternatives

App	Difference

M3U8 Player	Focuses on playback, debugging, and low-latency streaming preview, stronger than FetchV's weak preview function.

Reputation

FetchV receives positive feedback for ease of use, good speeds on supported sites, and handling m3u8 streams other tools miss, especially non-DRM content. Criticisms include unstable fluctuating speeds (0-8MB/s), lack of batch queues, no subtitle or DRM support, vague error messages, fixed download paths, and weak full playback previews. It suits casual single-clip downloads but frustrates for organized or complex media collection.¹²³
