Subreddit Trend Finder — Reddit Trend Tracker & Viral Post Monitor
Find trending Reddit posts before they go viral. Monitor any subreddit, track rising content across multiple communities, and surface the topics gaining real momentum — right now.
Whether you're a content marketer looking for trending topics, a social media manager hunting for viral content, or a brand analyst monitoring Reddit communities, Subreddit Trend Finder gives you ranked, scored, actionable Reddit trend data on demand.
What Is Subreddit Trend Finder?
Subreddit Trend Finder is an Apify Actor that scans one or more subreddits, scores every post by engagement velocity, and returns a ranked list of the content gaining the most traction right now.
Unlike a basic Reddit scraper that just dumps raw posts, this tool scores every post with a composite trend score based on how fast it's gaining upvotes and comments relative to its age. Posts gaining momentum fast rank higher than older posts sitting on stale upvotes — giving you a real signal of what's actually trending, not just what's already popular.
You can scan a single subreddit or dozens at once. Results are sorted globally across all subreddits so you always see the hottest content first, regardless of which community it came from.
Key Features
- Multi-subreddit scanning — monitor any number of subreddits in a single run, ranked together
- Velocity-based trend scoring — every post gets a composite trend score based on engagement speed, not just raw vote count
- Viral content detection — catches posts gaining momentum before they peak using multiple content source signals
- Rising trend signals — dedicated focus on content that's accelerating fast, the strongest early indicator of a viral trend
- Trend labels — posts are automatically labelled: 🔥 Viral, 📈 Rising Fast, ⬆️ Gaining, 📊 Steady
- Post type filtering — filter to link posts only (articles, news, videos) or text/discussion posts only
- Monitor mode — schedule recurring runs to track how post scores change over time with
scoreDelta - Flexible input — accepts subreddit names in any format:
gaming,r/gaming, or full Reddit URL - Clean structured output — every result includes rank, trend score, title, URL, upvote ratio, comment count, age, and more
- Separate dataset output — optionally split link posts and text posts into separate datasets for downstream processing

Monitor Mode — Track Reddit Trends Over Time
Enable Track Score Changes Between Runs to turn the actor into a full Reddit trend monitoring tool.
In monitor mode, each run saves a snapshot of post scores. On subsequent runs, every result includes a scoreDelta field showing exactly how many upvotes a post gained since the last snapshot. This tells you not just what's trending now, but what's accelerating — the posts gaining ground fastest between your monitoring windows.
Ideal setup: Use Apify's built-in scheduler to run this actor every 1–6 hours on your target subreddits. You'll get a continuous stream of trend data showing what's rising, what's peaked, and what's emerging — perfect for newsrooms, trading desks, marketing teams, and anyone who needs a real-time pulse on Reddit communities.
Trend Scoring Explained
Each post receives a composite trend score that prioritizes momentum over raw popularity. A post with 500 upvotes in 2 hours scores significantly higher than a post with 2,000 upvotes from 3 days ago. Posts that appear across multiple content sources receive a bonus, as cross-source appearance is a strong signal of breakout momentum.
The final score determines:
- 🔥 Viral — exceptional momentum, likely already spreading beyond Reddit
- 📈 Rising Fast — strong and accelerating, catch it now
- ⬆️ Gaining — solid upward trajectory
- 📊 Steady — consistent engagement but not spiking
Frequently Asked Questions
Can I scan multiple subreddits at once? Yes — add as many as you want. Results are ranked globally across all of them, so the #1 result is always the single most trending post across your entire subreddit list.
How is this different from just browsing Reddit? Reddit's native interface shows you what's popular right now, but it doesn't rank across multiple communities, doesn't score by velocity, doesn't filter by post type, and can't be automated or integrated into workflows. This actor gives you structured, scored, programmable data you can pipe into any system.
Can I use this for Reddit competitor monitoring? Yes. If your competitors are active on Reddit or have communities discussing their products, you can monitor those subreddits and track which content is gaining traction fastest.
Can I connect this to Zapier, Make, or other tools? Yes — all Apify actors integrate natively with Zapier, Make (formerly Integromat), Google Sheets, and hundreds of other tools via Apify's built-in integrations.
Can I schedule it to run automatically? Yes. Use Apify's built-in scheduler to run on any interval. Combined with monitor mode, this gives you a fully automated Reddit trend tracking pipeline.
What subreddits work best? Any public subreddit works. The most popular use cases involve news subreddits (r/worldnews, r/news), tech communities (r/technology, r/programming), finance (r/wallstreetbets, r/CryptoCurrency), entertainment, gaming, and niche interest communities relevant to specific industries.
Does it work with NSFW subreddits? Public NSFW subreddits are supported the same as any other subreddit.
How many subreddits can I scan in one run?
There's no hard limit. The more subreddits you add, the longer the run takes. For large-scale monitoring of dozens of subreddits, increase postsPerSource and maxResults to match your coverage needs.
Use Case Examples
Trending topic research across tech subreddits: Scan r/technology, r/programming, r/MachineLearning, r/artificial, r/webdev simultaneously. Get the top 50 most trending posts ranked by momentum. Use titles as content ideas or SEO topics.
Viral news monitoring: Scan r/worldnews, r/news, r/politics, r/europe on a 2-hour schedule. Catch breaking stories and trending narratives the moment they start gaining traction, before they hit mainstream media.
Finance & crypto sentiment tracking:
Scan r/wallstreetbets, r/CryptoCurrency, r/Bitcoin, r/ethereum, r/stocks with monitor mode enabled. The scoreDelta field shows which tickers and topics are accelerating fastest between runs.
Content calendar planning: Scan your niche subreddits weekly. The top trending posts are your audience telling you exactly what they want to read, watch, or hear about. Build your content calendar around real demand signals instead of guesses.
Competitor & brand monitoring: Scan subreddits where your brand, product, or competitors are discussed. Rising posts about competitors are early warnings. Trending discussions about problems your product solves are leads.
