Auto-detect ad SDKs. Generate app-ads.txt.
The only Unity Editor tool that scans your project, detects ad SDKs, and builds a verified app-ads.txt file checked against 2,000+ real ad network sellers.json files. Works with AdMob, AppLovin MAX, Unity Ads, and 9 more.
Why you need app-ads.txt
Google made app-ads.txt mandatory for all AdMob apps in 2025. Without a valid file, your ad requests may be dropped or limited. But only 24% of mobile apps have it set up correctly. BeamFlow makes it trivial: detect your SDKs, generate the file, host it free.
What the plugin does
Everything you need to set up app-ads.txt correctly, directly inside Unity. No manual copy-paste from ad network docs.
Auto-Detect Your Ad SDKs
Opens and scans your Unity project. Detects AdMob, AppLovin MAX, Unity Ads, ironSource, Meta, Vungle, Chartboost, and 5 more networks instantly.
Generate Complete app-ads.txt
Builds the correct lines for every detected network automatically. Handles direct and reseller entries. No manual copy-pasting from docs.
Verified Against Real Data
Optional BeamFlow API connection cross-checks every line against 2,000+ real ad network sellers.json files. Catches errors before ad networks do.
BeamFlow Recommended Lines
Our ad operations team curates extra verified lines that maximize your demand. Pre-checked by default. Uncheck any you don't want.
Built-in Hosting Options
No website? Get a free BeamFlow subdomain. Already have one? We show you the exact redirect rule. Both IAB-spec compliant.
Works Offline First
Built-in templates for every network work without internet. BeamFlow API is optional. No account required to use the core features.
12 ad networks auto-detected
The plugin scans your Unity project and detects these SDKs automatically.
Up and running in 30 seconds
Install, detect, generate. No coding, no configuration.
Install via Git URL
Unity Package Manager > Add package from Git URL. Or download the package directly. No account needed.
Open the Window
Window > BeamFlow > App-Ads.txt Manager. Your ad SDKs are auto-detected. Enter your AdMob publisher ID.
Host Your File
Click "Host on BeamFlow" for a free subdomain, or copy the file to your own website. Update your Play Store / App Store listing.
Two ways to host your app-ads.txt
Both IAB-spec compliant. Both work with AdMob, AppLovin, and every major ad network.
I have a website
Set up a 301 redirect from yourdomain.com/app-ads.txt to your free BeamFlow hosted URL. Keep your store listing as-is.
No app update required. Explicitly allowed by Google.
I don't have a website
Get a free BeamFlow subdomain like mygame.beamflow.co. Update your Play Store or App Store listing to that URL.
Same pattern Google recommends with Firebase Hosting.
How BeamFlow compares
No other tool integrates directly into Unity and auto-detects your ad SDKs.
