SubDeck: YouTube Subscription Manager

By: 0xHPZ Add-on
Organize YouTube subscriptions into folders and browse their uploads in a custom feed or multi-column deck.

Features & Capabilities

YouTube gives you one endless subscription feed. Subscribe to enough channels and the ones you actually care about get buried under the ones you do not.

SubDeck gives your YouTube subscriptions a better way to stay organized. Create folders, build custom feeds, filter content, and arrange channels side by side in a column deck, all without leaving YouTube.

FEATURES

Folders. Organize your subscriptions by topic, interest, or however you want. Create as many folders as you like, with over fifty built-in icons to make them easy to recognize.

Column Deck. Pin folders and channels side by side and scroll each column independently, giving you a TweetDeck-style way to follow multiple feeds at once.

Subscription Feed. See your subscriptions in one place with options to filter content, hide watched videos, and switch between grid and compact list views.

Content Filters. Focus your feeds on videos, Shorts, live streams, or upcoming streams.

Hide Watched. Automatically hide videos you've already watched based on a configurable watched threshold. You can also mark videos as watched without playing them or save them to Watch Later.

Manage Subscriptions. Manage all your channels from one place. Sort, filter, organize, and unsubscribe from multiple channels at once.

Search inside folders. Search for videos and channels within a specific folder instead of searching across all of YouTube.

Add channels without subscribing. Add a creator to a folder using a channel URL, @handle, or channel ID without subscribing to them.

Export and Import. Save your folders to a .json file and move them to another browser. Importing merges with your existing folders and never deletes anything.

Coming from PocketTube. Already organized your subscriptions in PocketTube (YouTube Subscription Manager)? Export your data there and import that file into SubDeck. Your folders and the channels in them come with you.

FREE TO USE

SubDeck is free to use with no account required.

The free plan includes unlimited folders and the core organization and browsing features. It includes up to 2 deck columns and 15 mark-as-watched actions per day.

Premium through Patreon lifts those limits and unlocks subfolders three levels deep, channel sorting by latest upload or subscriber count, custom folder colors and icons, folder duplication, and a one-click activity check across every channel. Premium members also get every new Premium feature we add in the future.

PRIVACY

SubDeck has no analytics, telemetry, advertising, or tracking.

Your folders are stored locally in your browser. No account is required to use the extension.

Optional Patreon membership verification is only used when you choose to connect Patreon.

FAQ

Do I need an account?

No. SubDeck works with the YouTube account you are already signed into. There is no sign-up, and nothing to create.

How many folders and channels can I add?

As many as you like. Folders are unlimited on both plans, and there is no cap on the channels a folder can hold.

Can I use SubDeck without a Premium membership?

Yes. The free plan includes unlimited folders and the core organization and browsing features. Premium adds subfolders up to three levels deep, removes the deck column and mark-as-watched limits, and unlocks additional organization features.
