Supports MP4, WebM, HLS (M3U8), and streaming video. Everything is processed locally inside your browser.

FEATURES

Automatic Media Detection

BoltStream works quietly in the background while you browse. When it finds a video or audio file on any page, it shows up in the popup with format, resolution, and file size — no need to copy-paste URLs or figure out where the video is hosted.

Universal web video downloader

Allows users to detect and download videos (MP4, WebM, HLS/M3U8 streams) from websites they are browsing, without needing to copy URLs or use external tools.

1. User browses a website with video content. 2. Extension's content script detects media resources (video/audio) in the background. 3. Detected media items appear in the extension popup with format, resolution, and size info. 4. User can preview the video, copy the URL, or click Download. 5. For standard videos, download initiates via browser's download API. 6. For HLS/streaming videos, a downloader tab on boltstream.app is opened with a task ID to process and convert the stream. 7. For Record Mode, the extension reloads the page and captures video data as it plays via MSE (Media Source Extensions).

Target users: General web users who want to save videos from websites / Users who encounter streaming video formats like HLS/M3U8

The extension delegates HLS and Record Mode downloads to an external web service (boltstream.app), so the actual download processing happens server-side despite the 'no data leaves your browser' claim. This may be a discrepancy between marketing and implementation.
Cannot confirm whether boltstream.app requires account creation for the downloader pages to function, as the source code only shows URL generation, not the destination service's behavior.
The extension is relatively small (628KiB) with 72 files, mostly localization files. The core logic is in background.js, popup.js, and content scripts.

Monetization

No paid features detected

No evidence of paid features, subscription gates, payment platforms, or upgrade prompts in the extension code. The extension uses chrome.storage for local settings and chrome.downloads for saving files. The keyword 'pro' found in static analysis was false positives (e.g., 'progress-bar', 'Promise', 'prova' in Italian). No Stripe, Paddle, license keys, or paywalls detected.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension itself does not implement login, but the core download workflow (especially for HLS/M3U8 and Record Mode) requires opening a downloader page on boltstream.app with a taskId. The popup.js code (lines 397-404, 444-450) creates new tabs pointing to https://boltstream.app/hlsdownloader, staticdownloader, or msedownloader with query parameters. While basic static video downloads might work locally, the architecture relies on the boltstream.app web service for processing streaming content. The extension description says 'no accounts', but the technical implementation delegates to an external service. However, since the extension explicitly states 'no accounts' and the download of standard MP4/WebM appears to happen via the browser's native download API (chrome.downloads), the login requirement is primarily for the advanced streaming features handled by the destination service.
