Vidora vs Stream Recorder: HLS-Focused Comparison

1. Pure HLS focus vs HLS+DASH+AES

Stream Recorder was built around one core use case: capture an HLS m3u8 stream playing in the browser and save it as a video file. It does this job solidly. The extension detects m3u8 requests in the network layer, lets you pick from detected streams, and downloads segments. For simple public HLS streams, this is a clean workflow.

Vidora shares the same HLS core but extends it in three directions:

• DASH .mpd: Vidora detects DASH manifests alongside m3u8. Platforms like Vimeo, Bunny.net, and some enterprise video hosts serve DASH rather than HLS. Stream Recorder does not cover this. Our DASH MPD downloader guide explains the protocol in detail.
• AES-128 decryption: Vidora fetches the key URL within the browser session, decrypts each segment before muxing, and writes a clean decrypted MP4. Stream Recorder's AES support is inconsistent, especially for per-segment key rotation. See the full technical breakdown in our encrypted m3u8 guide.
• Progressive MP4 fallback: if the page serves a direct MP4 alongside or instead of an HLS stream, Vidora detects it and includes it in the download list.

2. Audio rendition handling

This is the most technically demanding aspect of modern HLS. Apple-style adaptive playlists often separate audio into its own rendition playlist, declared in the master m3u8 via EXT-X-MEDIA TYPE=AUDIO. A minimal HLS downloader that only follows the video variant will produce a silent MP4.

Vidora was specifically engineered to handle this pattern. When it encounters a master playlist, it parses both the video variant and any declared audio renditions, downloads the segment streams in parallel, and muxes them correctly into a single MP4. This was a hard-won fix for Vimeo support in particular (detailed in the engineering notes below).

Stream Recorder handles some cases of separate audio renditions but has known issues with complex Apple HLS configurations. If you regularly download content from Vimeo, Apple HLS players, or platforms that use separate audio groups, Vidora is the more reliable choice.

3. Detection accuracy

Both extensions hook into the browser's network request interception API (Chrome's webRequest or declarativeNetRequest). Detection accuracy depends on how early the extension intercepts the request and whether it filters correctly for m3u8 content types vs other .m3u8-like URLs.

Stream Recorder has a strong reputation for detection reliability on straightforward HLS streams. It has been in the market longer and has refined its detection logic across many platform updates.

Vidora intercepts at the service worker level and cross-validates by content-type and URL pattern. It additionally detects DASH manifests (.mpd files), which Stream Recorder misses entirely. On a standard test across Vimeo, Bunny.net, Wistia, and Loom, Vidora reliably detects all stream types where the page uses standard HLS or DASH delivery.

For detecting the m3u8 URL on a page without downloading, our free M3U8 URL Detector works without any extension install.

4. UX and one-click flow

Both tools present a popup when you click the extension icon. Stream Recorder shows a list of detected streams with format and size information. Vidora shows detected streams grouped by type (HLS variants by quality, DASH variants, direct MP4), with resolution labels where available.

Stream Recorder's popup is minimal by design. For users who want to pick a stream and click go, this is fine. Vidora's popup is slightly denser because it surfaces more data (audio renditions, DASH vs HLS source, quality labels) but the primary action is still one click.

One notable difference: Stream Recorder sometimes requires the user to manually select the correct stream from a list that includes non-video m3u8 requests (thumbnails, subtitles, preview playlists). Vidora filters these out and presents only playable stream candidates.

5. Pricing

Stream Recorder offers a free tier (limited features or download count per day) and a paid plan. The exact pricing has shifted over time; check the Chrome Web Store listing for the current offer.

Vidora is $9.99 one-time with a lifetime license. No subscription, no per-download limits. There is a 30-day money-back guarantee. For users who download content regularly, the total cost of ownership is lower than a recurring subscription.

6. Who should pick each

Pick Stream Recorder if:

• You download exclusively from simple HLS streams and do not need DASH support.
• You are comfortable manually selecting from a list of detected streams.
• You want a free option to get started before committing to a paid tool.
• The streams you target are public, not AES-128 encrypted, and do not use separate audio renditions.

Pick Vidora if:

• You encounter DASH .mpd streams regularly (Vimeo, Bunny.net, enterprise players).
• You need reliable AES-128 decryption for encrypted course or training content.
• You download from platforms with separate audio renditions (Apple HLS, Vimeo).
• You prefer clean automatic stream filtering over manual selection.
• You want a one-time payment with lifetime access and no download limits.
