Introduction

If you’ve ever watched a live stream and noticed fun pop-ups when someone follows, donates, or subscribes, those are stream alerts. They’re more than just flashy graphics—they create engagement, reward viewer interaction, and make your stream look professional. In this guide, we’ll walk you step by step on how to add stream alerts to OBS like a pro.

What Are Stream Alerts?

Stream alerts are real-time notifications that appear on your stream whenever a viewer takes an action.

Types of Alerts

• Follows – Acknowledge new community members.

• Subscriptions – Celebrate loyal viewers supporting your channel.

• Donations & Tips – Thank your supporters financially contributing.

• Bits or Stars – Recognize micro-donations on Twitch or Facebook.

• Raids & Hosts – Show appreciation for other streamers boosting your channel.

Why Use Stream Alerts in OBS?

Adding alerts isn’t just for fun—it’s powerful for growth.

• Keeps Audience Engaged – Viewers love seeing their names on screen.

• Boosts Channel Growth – Encourages more follows and donations.

• Adds Professionalism – Makes your stream look polished and interactive.

Tools You’ll Need

Before starting, make sure you have:

• OBS Studio – Your streaming software.

• Stream Alert Provider – Streamlabs, StreamElements, or alternatives.

• Browser Source – OBS feature to embed alerts.

Setting Up Alerts in OBS

Let’s break it down:

Step 1: Choose a Stream Alert Provider

Most streamers use Streamlabs or StreamElements. Both are free, beginner-friendly, and offer tons of customization.

Step 2: Create or Customize Your Alerts

Log into the provider with your Twitch, YouTube, or Facebook account. Then set up alert types, pick animations, colors, and sounds.

Step 3: Copy Alert URL

Once you save your alert, you’ll get a unique URL. This URL is what OBS needs to display alerts.

Step 4: Add Browser Source in OBS

In OBS, click the “+” icon under Sources → Select Browser Source → Paste the Alert URL.

Step 5: Adjust Size and Position

Resize and drag alerts to your desired location on your screen overlay.

Choosing the Right Stream Alert Provider

• Stream Grafix – Paid options with premium-quality alert packs.

• StreamElements – Lightweight, browser-based, great for advanced customization.

• Streamlabs – Easiest to use, tons of free themes.

Customizing Stream Alerts

• Animations & GIFs – Add funny GIFs or cool effects.

• Sounds & Music – Upload MP3/WAV clips.

• Alert Duration – Keep alerts around 5–8 seconds.

• Branding – Match colors and style with your stream’s theme.

Testing Your Stream Alerts

Always test before going live!

• In Streamlabs/StreamElements, hit the Test Alert button.

• In OBS, check that alerts pop up in preview mode.

Advanced Settings

• Multiple Alerts – Set different designs for subs, bits, or raids.

• CSS Customization – Advanced users can tweak designs with code.

• Overlays – Add animated frames around alerts for a pro look.

Troubleshooting Stream Alerts in OBS

• Alerts Not Showing – Check the Browser Source URL and internet connection.

• Lag or Delay – Lower file sizes for animations.

• Sound Issues – Ensure OBS captures browser audio.

Tips for Better Stream Alerts

• Keep alerts short and fun—avoid blocking gameplay.

• Use unique alerts for milestones (e.g., 100th sub).

Best Practices for Stream Engagement

• Personally thank viewers when alerts pop up.

• Encourage donations with fun sounds or animations.

• Create hype moments with milestone alerts.

Free vs. Paid Alerts

• Free Alerts – Available on Streamlabs, StreamElements, and community sites.

• Paid Alerts – Offer higher-quality graphics, branding options, and uniqueness.

Maintaining Professionalism

• Don’t overuse giant or overly long alerts.

• Stick to one consistent design for branding.

Stream alerts bring life to your broadcasts. By following these steps—choosing a provider, setting up alerts, customizing them, and testing—you’ll transform your stream into an interactive experience viewers love. Whether you use free or paid alerts, the key is keeping them fun, on-brand, and engaging.
