Creating an App to Track and Engage with Viral Reddit Posts

📈 Every day, Reddit posts go viral—but most people miss the chance to capitalize on them.

What if you could get notified the moment a post starts going viral, giving you the chance to engage while the conversation is still hot? By commenting early on trending posts, you could drive massive exposure for you or your brand and capture thousands of impressions.

In this edition of Easy Startup Ideas, we’ll show you how to build a Reddit monitoring app that alerts you when posts are already going viral—so you can engage early and maximize your reach.

Today’s Idea

Create a SaaS platform that allows users to monitor specific subreddits and receive real-time alerts when posts are rapidly accumulating upvotes and comments (indicating virality).

Ideal Customer

• Reddit Power Users – Users who want to stay ahead of trending content to increase karma and influence within specific subreddits. Spotting viral posts early allows them to engage quickly and maximize visibility.

• Content Creators – YouTubers, streamers, and bloggers who can use trending topics to create timely content and boost traffic. Engaging with a post early—through comments or content referencing it—can drive significant exposure.

• Social Media Managers – Professionals managing brand or influencer accounts can comment on viral posts early to get thousands of impressions and drive traffic back to their profiles or content.

• Marketers and Researchers – Tracking emerging discussions allows marketers to refine messaging and capitalize on trending themes before they hit the mainstream. Commenting early on a viral post positions brands as part of the conversation.

• Reddit Moderators – Moderators can use the app to manage trending posts more effectively, catching viral content early to moderate discussions and handle rule enforcement before things get out of hand.

Why It Will Succeed

1. Faster Than Competitors

   • Most similar tools (like GummySearch) focus on keyword monitoring rather than real-time viral detection.

   • Custom virality algorithm provides real-time insights faster than existing services.

2. Custom Algorithm and Personalization

   • Adjustable scoring model allows users to define virality thresholds based on their preferences.

   • No one-size-fits-all approach → greater accuracy and relevance.

3. Scalable Infrastructure

   • Using OAuth-based tokens avoids Reddit’s global rate limits.

   • Background job system scales efficiently with large user bases.

4. Multi-Channel Notification System

   • Browser, email, push, Slack, and Discord → more engagement and better user retention.

5. Data-Driven Insights

   • Real-time and historical performance data provides deeper insights into post trends.

Getting Started and Building an MVP

1. Set Up Reddit OAuth

1. Register the app on Reddit:

   • Go to https://www.reddit.com/prefs/apps.

   • Select "Create App," choose "Script" or "Web app," and set the redirect URI to match your app's domain (e.g., http://localhost:3000/api/auth/callback/reddit).

2. Install and configure NextAuth.js:

   • Install NextAuth.js.

   • Create an API route in your Next.js project to handle Reddit OAuth.

   • Store Reddit API credentials (client_id, client_secret) in environment variables.

3. Set up authentication:

   • Create a login button that allows users to sign in using Reddit.

   • Test the authentication flow to confirm successful sign-in and token storage.

2. Build the Frontend (Next.js + Tailwind)

1. Create a Next.js project and install Tailwind CSS.

2. Configure Tailwind to recognize your components and pages.

3. Create a simple dashboard:

   • Display a clean interface using Tailwind CSS.

   • Add a login button and display user session data.

   • Test to confirm proper UI rendering.

3. Create the Polling System (Agenda.js + Reddit API)

1. Install Agenda.js (or Bull) for background jobs.

2. Set up MongoDB using MongoDB Atlas or a local instance.

3. Define a polling job:

   • Schedule the job to run every 5 minutes.

   • Use per-user OAuth tokens to avoid rate limits.

   • Confirm that the polling job can access Reddit API data.

4. Test polling by logging the retrieved data from Reddit.

4. Create the Virality Scoring Model

1. Create a formula that factors in upvotes per minute, comments per minute, engagement ratio, post age, and awards.

2. Allow users to adjust the weights of these factors.

3. Store the scoring model in the database and apply it to incoming post data.

4. Test different thresholds to fine-tune the virality detection.

5. Set Up Notifications (Firebase + WebSockets)

1. Set up Firebase using Firebase to handle push notifications.

2. Create a WebSocket connection for real-time browser notifications using WebSockets.

3. Configure email notifications using a service like Resend.

4. Allow users to enable/disable Slack and Discord notifications.

5. Test by triggering notifications when a post exceeds the virality threshold.

Final Checkpoint:

• Reddit login and OAuth working

• Dashboard with subreddit tracking

• Polling system retrieving real-time data

• Virality scoring model working

• Real-time notifications delivered across all channels
