How it works
Scroller fetches media posts from every subreddit in your source list, merges them into one feed, and displays them in a configurable grid or single-column layout. Unlike browsing Reddit directly, you see content from all your chosen subreddits mixed together in one place, with built-in media type filters, autoscroll, and quick actions.Getting started
Add subreddits
Type a subreddit name into the input field and press Enter or click the add button. Repeat for as many subreddits as you like. Your sources appear as removable chips above the input.
Configure your feed
Set your preferred layout, sort order, time window (for Top sort), and media type filters. See the sections below for details on each option.
Refresh to load
Click the Refresh button to fetch posts from all your subreddits. The feed loads automatically on first visit if you have saved subreddits from a previous session.
Managing subreddits
Adding sources
Type any subreddit name into the input field and press Enter. You can add as many as you like. Duplicate subreddits are automatically prevented.Favorite subreddits
You can maintain a list of favorite subreddits for quick access:- Favorites are stored locally and appear as a dropdown menu (star icon) in the controls panel.
- Click a favorite from the dropdown to instantly add it to your current source list.
- Favorites that are already in your active list are hidden from the dropdown to avoid duplicates.
- Favorites are marked with a gold star icon on their chip when they are in the active source list.
Clearing sources
Use the X button next to the favorites star to clear all subreddits at once, or remove individual subreddits by clicking the X on each chip.Layout modes
Scroller offers four layout options:| Mode | Description |
|---|---|
| Compact | Dense grid (2-7 columns depending on screen size). Square aspect-ratio tiles. Best for scanning large amounts of content. |
| Large | Medium grid (1-3 columns). Square tiles with more breathing room. Good default for mixed browsing. |
| Extra Large (XL) | Large cards (1-2 columns). Bigger media with more detail visible at a glance. |
| Feed | Single-column layout (max-width centered). Shows each post with its full title above the media, similar to a traditional social feed. Images display at their natural aspect ratio. |
Sort options
| Sort | Description |
|---|---|
| Hot | Trending posts from each subreddit (default) |
| New | Most recently posted content |
| Top | Highest-voted posts within a time window |
Changing the sort mode or time filter automatically refreshes the feed with fresh content — no need to click Refresh manually.
Media type filters
Toggle which media types appear in your feed:| Filter | What it includes |
|---|---|
| Images | Static images (JPG, PNG, WebP, etc.) |
| Videos | Video content (MP4, WebM, Reddit-hosted video) |
| GIFs | Animated content (GIFs, GIFV, Gfycat, Redgifs, Giphy) |
Autoscroll
Scroller shares the same autoscroll system as Gaslighter. A floating control widget appears in the bottom-right corner of the screen.Enable autoscroll
Toggle the Autoscroll switch in the floating widget, or use the Autoscroll toggle in the controls panel.
Adjust speed
Use the speed slider (1-10) or the three preset buttons:
- Slow (10) — relaxed, hands-free pace
- Medium (5) — comfortable browsing speed
- Fast (2) — rapid scanning
Pause and resume
Autoscroll pauses automatically when you:
- Scroll manually (mouse, touchpad, or touch)
- Use keyboard navigation (arrow keys, Page Up/Down, Spacebar)
- Open the fullscreen media modal
- Interact with quick-action buttons (download, save, etc.)
The autoscroll speed slider in the controls panel provides finer granularity (1-10 scale) compared to the three-preset floating widget. Both control the same underlying speed.
Fullscreen media modal
Click any post to open it in a fullscreen viewer:- Desktop: Arrow buttons on the left/right edges, keyboard arrow keys, or click the side regions to navigate. Press Escape to close.
- Mobile: Swipe left/right to navigate. Swipe down from the top to close. Double-tap to zoom images (up to 4x). Pinch to zoom further.
Quick actions
Hover over any post in the feed (or view it in the modal) to reveal action buttons:- Download — save the image or video directly to your device
- Send to Joip — transfer the media to other Joip tools (sessions, BabeCock, etc.)
- Save to Vault — store the media in your personal Media Vault for later use
Infinite scrolling
Scroller loads more content automatically as you approach the bottom of the feed. An IntersectionObserver sentinel element triggers the next batch fetch with a 300px look-ahead buffer. Content from all your subreddits is fetched in parallel for fast loading. Deduplication ensures you never see the same media URL twice in the same feed session. When all unique content has been exhausted for the current sort and filters, a subtle “End of feed” indicator appears.Collapsible controls panel
The settings panel at the top can be collapsed by clicking the chevron button. This gives you more screen space for the feed while keeping the Refresh button accessible at all times.Settings persistence
All Scroller settings are saved automatically to your browser’s local storage under the keyscroller_user_settings. This includes:
- Active subreddit list and favorite subreddits
- Layout mode, sort mode, and time filter
- Media type filter toggles (Images, Videos, GIFs)
- Autoscroll enabled/disabled and speed
Tips and best practices
Building a great multi-subreddit feed
Building a great multi-subreddit feed
Mix subreddits of different sizes and posting frequencies. Combining a high-volume subreddit (like
pics) with niche ones ensures a steady stream of content while keeping things interesting.Using favorites for quick setup
Using favorites for quick setup
Save your most-used subreddits as favorites. When you want to browse a specific theme, clear your current sources and quickly add the relevant favorites from the dropdown — much faster than typing each one.
Optimizing autoscroll for different moods
Optimizing autoscroll for different moods
- Lean-back browsing: Large or Feed layout + Slow speed. Great for relaxed viewing.
- Discovery mode: Compact layout + Medium speed. See a high volume of content quickly.
- Quick scan: Compact layout + Fast speed. Rapidly skim through a subreddit’s best content.
Filtering for specific content types
Filtering for specific content types
Use the media type toggles to focus your feed. For example, disable Videos and GIFs to create an images-only feed, or disable Images to watch only video and GIF content. Filters apply instantly without re-fetching.
FAQ
How is Scroller different from Gaslighter?
How is Scroller different from Gaslighter?
Scroller shows genuine content from your chosen subreddits — each post’s title matches its own media. Gaslighter swaps the media, pairing titles from one subreddit with images from a completely different one. Scroller is for curated browsing; Gaslighter is for creative mash-ups.
Does Scroller use credits?
Does Scroller use credits?
No. Scroller is a free tool that does not consume any credits.
Why does the feed say 'End of feed' so quickly?
Why does the feed say 'End of feed' so quickly?
This happens when your subreddits have limited media content for the selected sort and time window. Try switching to a different sort mode (Hot, New, or Top), expanding the time window for Top posts, or adding more subreddits to increase the content pool.
Can I save my feed as a session?
Can I save my feed as a session?
Scroller sessions can be saved server-side via the API. Your subreddit list, sort settings, and filter preferences are preserved. However, the primary way most users save their configuration is through the automatic local storage persistence, which requires no manual action.
Are my settings saved across devices?
Are my settings saved across devices?
Settings are stored in your browser’s local storage, so they are specific to each browser and device. They are not synced to your Joip account. Saved scroller sessions (via the API) can be accessed from any device.
Why are some images not loading?
Why are some images not loading?
Some Reddit images are hotlink-protected. Scroller automatically retries failed images through a server-side proxy. If an image still fails to load, a placeholder icon is shown. This is uncommon but can happen with certain image hosts.
