YT Channel Downloader: a PyQt front end for pulling whole channels

What the application is for

YT Channel Downloader is an intuitive desktop application built to simplify the process of downloading YouTube media content, and the description is more specific than the project name suggests.

The repository description calls it a Qt GUI app that makes it easy to selectively download multiple videos at once from Youtube and other platforms channels. The key word is selectively, and that word separates this from every other yt-dlp wrapper.

The readme explains the design in terms of the underlying tool. It leverages the robustness of yt-dlp and is enriched with a modern PyQt 6 GUI, and the pyproject description is blunt about the scope: a desktop app for downloading entire YouTube channels or playlists via yt-dlp.

So the value proposition is not new downloading capability. yt-dlp already handles the downloading itself, across the long list of sites and formats it supports. What the application adds is the part of the workflow that yt-dlp's command line makes awkward, which is deciding what you actually want from a list of two hundred videos before spending an hour and several gigabytes on the ones you will never watch.

The platform support is broad for a Qt application. The readme links screenshots for Windows, Linux and macOS, the pyproject classifies it as Operating System:: OS Independent with Environment:: X11 Applications:: Qt, and the install instructions cover PyPI, a Debian package, source builds on macOS and Linux, and Windows binaries.

The application is MIT licensed and published on PyPI, with binary releases on the GitHub releases page and SourceForge, and there is a Ko-Fi donation link. The recent releases are v0.8.8 from 2026-04-01, v0.8.6 from 2025-12-28 and v0.8.0 from 2025-11-26, and the last push was on 2026-07-10.

The workflow the feature list describes

The feature list reads as a description of a workflow rather than a set of buttons, and the order of it is the workflow.

Fetch and Replace or Fetch and Add covers how new results join the current list, either replacing it or appending to it. Fetch Video Listings takes a YouTube video, playlist or channel URL and returns a list of matching items, and Search Within Fetched Items filters that list by title with a built-in search field.

Then Selective Download is the step the whole application exists for: choose exactly which videos you want to download, or select all at once.

Before you commit to that, Quality Control lets you specify video and audio quality or opt to download only the associated audio track, so an archive of a podcast channel does not carry video you will never watch.

Size and Time Estimates preview the total download size and ETA before starting, with cancelable calculations. The cancelable part matters more than it sounds, because the estimate is computed from metadata for every item in the list, and on a large channel that calculation is itself slow enough to want to abandon.

Large-List Handling is the answer to that. Channels can be fetched in batches with Fetch Next, and playlists use configurable fetch limits to keep fetching responsive. So the application does not try to enumerate a whole channel at once, which is both a memory decision and a responsiveness one.

Then the output side. Download Marking keeps track of downloaded files for easier management, so a second run does not re-download what you already have. Thumbnail Previews and Downloads shows thumbnails as soon as items are fetched, and saves them alongside the downloads. Playlist Downloads and Channel Downloads cover the bulk cases, downloading all or some videos from either kind of URL.

Single Video or Audio Downloads handles the other case, pasting any supported link, with the readme listing YouTube, Vimeo, Twitch, SoundCloud, Facebook, Instagram, Twitter/X, TikTok, Udemy, Reddit and more via yt-dlp, while noting that bulk channel and playlist fetching remains YouTube-only.

That asymmetry is worth internalising. The tool is not merely a channel downloader, and its channel fetching is not general. It is a YouTube bulk tool with a general single-item downloader attached.

The dependency problem, and why a JavaScript runtime matters

The most operationally important section of the readme is about installing a JavaScript runtime, and it is a good example of a downstream project absorbing an upstream platform problem.

yt-dlp can use a JavaScript runtime to parse YouTube player code, and having one installed reduces missing formats and silences runtime warnings. The Python dependency install includes yt-dlp's default extras, but it does not install an external runtime for you. The readme then lists the options, Node.js via the package manager on each platform, or Deno.

The application also has runtime detection. If an optional JavaScript runtime for yt-dlp is missing, you get guided prompts rather than a silent failure. That is the right call, because the symptom without a runtime is a download that works but is missing formats, which is easy to mistake for the tool being broken.

There is a second, sharper version of this issue in the changelog. Version 0.8.9 raised the minimum yt-dlp dependency to 2026.03.17 to fix the YouTube HTTP 403 download failures, and documented that PyPI users should upgrade yt-dlp.

And the install section expands on that in a way that is genuinely useful. If yt-dlp is already present in your Python environment, upgrade it alongside the app, because pip install yt-channel-downloader can otherwise keep an older yt-dlp that still satisfies the dependency floor but no longer works reliably against recent YouTube player changes.

That is a real pip behaviour and a real trap. A dependency floor is a minimum, not a pin, so an already-installed older yt-dlp in the same environment can satisfy the constraint while being functionally broken, and the install command will not touch it.

The supported fix is explicit:

pip install --upgrade yt-channel-downloader yt-dlp
yt-channel-downloader

FFmpeg is the other external requirement. It is needed for the app to work correctly, and the readme gives per-distribution install commands for macOS with Homebrew, Debian and Ubuntu, Fedora and Arch Linux, and tells you to check with ffmpeg -version first.

The PyPI install itself is the simplest route, and it pulls yt-dlp's recommended companion components such as yt-dlp-ejs:

pip install yt-channel-downloader

Packaging, the cookie login, and what is still missing

The packaging story covers four routes, and the .deb route is the one with the most specific instructions.

For Debian and Ubuntu you download the latest .deb from the releases page, or build one with ./scripts/create_binary.sh then ./scripts/create_deb.sh, and install it with apt so dependencies are resolved:

sudo apt install ./yt-channel-downloader_<version>_<arch>.deb

The reason apt rather than dpkg matters is dependency resolution, and the reason the package is built at all is that a desktop application with PyQt6, yt-dlp and FFmpeg as dependencies is unpleasant to install by hand on a distribution that does not package them.

The console entry point is yt-channel-downloader, mapped to yt_channel_downloader.__main__:main, and the project name on PyPI is yt-channel-downloader with the import package named yt_channel_downloader.

The most interesting feature is the browser-cookie login. You can reuse a signed-in browser profile for private, age-restricted or premium YouTube content. The readme is careful about the scope of this, noting that some providers, for example Udemy or other premium services, still require valid browser cookies or provider-specific credentials, and that the in-app browser-cookie login flow is primarily intended for restricted YouTube downloads.

That is the right way to frame a feature like this. It is a legitimate need, since YouTube restricts some content behind a login and yt-dlp has supported browser cookies for years, but it also hands the application access to a session cookie, and the readme is explicit about which providers it is really aimed at.

The coming soon list is short: download history tracking and a link to suggest a feature. The absence of history tracking is the most interesting gap, because Download Marking already tracks which files have been downloaded in the current session, and a persistent history across runs is what you would want for an archive tool that you run against a channel every few months.

The package metadata is worth a note for anyone packaging the app elsewhere. The classifiers cover Python 3.9 through 3.13, the development status is 4, Beta, the intended audience is End Users/Desktop, and the topic is Multimedia :: Video. The runtime dependencies are deliberately few: appdirs, requests, yt-dlp with its default extras, and PyQt6.

Why a GUI on top of yt-dlp is worth writing

It is reasonable to ask why this project exists at all, since yt-dlp is a command line tool that everyone in this space already uses, and the answer says more about the users than about the code.

The problem with downloading a channel from the command line is not the download. It is the selection. A channel URL expands into a list of hundreds of items, and yt-dlp's flags for narrowing that list are written in terms of what you can express on one line. You can express conditions on one line, but deciding that you want the twenty episodes from a particular series, or everything since a certain date except the ones you already have, or the video and the audio separately, is awkward to express and impossible to preview.

The GUI solves the preview problem specifically. Size and Time Estimates give you the total download size and ETA before starting, with cancelable calculations. That is the piece the command line genuinely cannot do, because it requires enumerating the whole selection and asking each item for its metadata before deciding to fetch it, and no flag combination does that interactively.

It also solves the review problem. Search Within Fetched Items lets you filter the fetched list by title, so you can narrow a large channel down to a subset by typing rather than by remembering index numbers, and Download Marking keeps track of what has already been downloaded so a second pass over the same channel picks up only what is new.

The batching in Large-List Handling is the third piece, and it is a design response to the scale of the problem. Fetch Next for channels and configurable fetch limits for playlists mean the application never has to hold a whole channel in memory at once, and you can see the first page of results while the rest is still loading. For a channel with thousands of uploads, that is the difference between a usable tool and one that appears to hang.

None of this makes yt-dlp worse. It makes yt-dlp the right engine for a different audience. The application is classified as End Users/Desktop rather than for developers, and the feature list is written for someone who wants their podcast archive downloaded with the right audio quality, not for someone who wants to script it.

Editorial conclusion

Adopt YT Channel Downloader if you want to archive a channel or a playlist and would rather select the videos by hand than let a command line download everything. Do not adopt it if you want unattended batch runs, because the coming soon list still includes download history tracking and the whole interface is a GUI. Before you commit, install a JavaScript runtime alongside it, because the readme is explicit that a missing runtime reduces the YouTube formats you get and produces warnings.
