How It Works
Connect your payment platforms
Link CashApp, Venmo, PayPal, Ko-fi, Patreon, Buy Me a Coffee, or Fourthwall to your StreamAlert account.
Copy your custom alert box URL
StreamAlert generates a unique browser source URL for your custom alert box. Copy it from your dashboard.
Add to OBS as a browser source
Paste the URL into a new OBS browser source. Donations, tips, memberships, and orders will display as on-stream alerts automatically.
Why Use Custom Alerts?
No Third-Party Account Needed
StreamAlert provides a dedicated widget URL that works as a standalone OBS browser source. Streamers paste the URL into OBS and alerts display immediately — no Streamlabs or StreamElements account required.
All Alert Types
StreamAlert custom alerts support donations, tips, memberships, and orders from all 7 payment platforms. Streamers get a unified alert stream through a single browser source without managing multiple integrations.
Fully Customizable
StreamAlert lets streamers fully customize alert appearance — upload sounds, images, GIFs, configure colors, fonts, and animation styles. Each alert matches the streamer's brand for a professional on-screen experience.
Works Everywhere
StreamAlert custom alerts work on any streaming platform that supports OBS browser sources — Twitch, YouTube, Kick, Facebook Gaming, and TikTok Live. Streamers are not locked into any specific ecosystem.

Customization Features
Configure how alerts appear on your stream. Each alert type (Donations, Memberships, Orders) can be customized independently from the StreamAlert dashboard.
GIF Animation
Set a custom GIF that plays when an alert fires. Upload your own or use a URL — the GIF displays above the alert text on stream.
Alert Sound
Upload a custom sound effect (MP3 or WAV) that plays with each alert. Adjust the volume per alert type so donations, memberships, and orders each have their own audio.
Message Template
Write your own alert text using placeholders like {name}, {amount}, {tier}, and {source}. For example: "{name} just tipped {amount}!" — each alert type has its own template.
Source Logo
Toggle the payment platform logo (CashApp, PayPal, Patreon, etc.) on or off per alert type. When enabled, the logo appears next to the alert text on stream.
Duration
Control how long each alert stays visible on stream, from 3 to 15 seconds. Set shorter durations for high-volume streams or longer for fewer, more impactful alerts.
Test & Preview
Send a test alert from the dashboard to see it live in OBS before going live. Preview with real data to make sure your GIF, sound, template, and duration look right.
