User reviews

Users appreciate Cat Catch for its ease of use, effective video downloading capabilities from various platforms, and user-friendly interface. It is considered a top choice among online media downloaders. Common issues include inability to download some Bilibili videos, duplicate file downloads, problems with merged video/audio playback quality, errors with large file downloads, and lack of Incognito mode support. Overall, it is well-regarded but would benefit from improvements in these technical areas.

Effectively downloads videos from multiple platforms such as YouTube, Tencent Meeting recordings, and Bilibili.
Reliable media sniffer that successfully captures video and audio streams for download.
Offers merged downloads of audio and video files, providing convenient one-click media saving.
Highly praised as a strong alternative to other download managers and extensions.

Cons

Cannot download some videos from Bilibili recently, indicating partial site support issues.
Downloads duplicate files with the same name automatically, resulting in multiple copies.
Merged video and audio files sometimes result in corrupted or gray screen videos with no sound when played.
Incurs errors when downloading large files over 2GB, including array buffer allocation failures.
Extension does not work in Incognito (private) mode, limiting usage scenarios.
