If you are searching for AdGem alternatives, you are probably at the point where you have already tried AdGem and something about it no longer fits. Maybe the SDK integration is awkward for your stack, maybe reporting arrives too late to act on, maybe you need a platform that is not tied to a single walled garden.
This page lists five offerwall and rewarded-monetization platforms you can evaluate instead, what each is actually good at, and where each one falls short. Perkox is included because we build it, and we have tried to be honest about its limitations rather than pretend it wins every dimension.
If you want the short answer: Perkox is the strongest fit for cross-platform apps (Flutter, React Native) that need native SDKs and real-time reporting. ironSource (Unity LevelPlay) is the choice if you want the largest advertiser demand pool and do not mind a heavier integration. Digital Turbine (formerly Fyber) is worth comparing if you run rewarded video alongside offers. Ayet Studios is a credible mid-sized network. Adjoe is worth a look if your traffic is Android-heavy.
Why Developers Are Looking for AdGem Alternatives
The most common reason is an integration that does not fit the app. AdGem is strong on Android and iOS, and it has a web-based fallback for environments where a native SDK is impractical. If your app is built with Flutter or React Native, you are likely looking for a platform with a first-class cross-platform SDK rather than one you wrap for the web.
The second reason is reporting cadence. Publishers who need to see which campaign, which geo and which placement is producing revenue while it is still running need reporting that is not a nightly export. The third is fraud handling: when a network validates offers only on the client, a motivated publisher can manufacture completions, and you end up paying for traffic that never existed.
The fourth reason is payout schedule and transparency. If your cash flow depends on a specific payment date or a minimum threshold you cannot control, that becomes the deciding factor regardless of how good the catalog is.
What to Look For in an Offerwall Platform
- SDK support that matches your stack. A native Android and iOS SDK is the baseline. If you use Flutter, React Native, Unity or a native cross-platform framework, a web-view wrapper costs you offer-fill rate and makes attribution harder.
- Server-side offer validation. Client-only validation is a hole in your fraud model.
- Reporting you can act on. Real-time or near-real-time breakdowns by campaign, geo, placement and device.
- Offer catalog breadth. A wide catalog gives you more placements to rotate and more room to tune for each user.
- MMP integration. AppsFlyer, Adjust and Singular integrations determine whether your measurement lines up with your ad spend.
- Payout terms you can plan around. Schedule, threshold, currency and method.
Platform #1: Perkox
Overview
Perkox is a rewarded monetization platform built around cross-platform mobile development. Publishers get access to more than 1,200 offers spanning surveys, app installs, gaming achievements and sign-ups, with coverage across tier-1 and emerging markets. It provides native SDKs for Flutter and React Native, server-side offer validation, real-time analytics, and MMP integrations with AppsFlyer and Adjust.
SDK Support
Android, iOS, Flutter and React Native, all native. No web-view wrapper for the main SDK paths.
Key Features
- Offer catalog of 1,200+ offers with global coverage
- Server-side validation and device fingerprinting
- Real-time dashboard with granular metrics
- MMP integrations for AppsFlyer and Adjust
- Multiple payout schedules with transparent reporting
Best For
Cross-platform apps, especially those on Flutter or React Native, that need server-side validation and reporting they can act on while campaigns are running.
Limitations
Perkox is newer than the established networks, so the advertiser demand pool and the long-tail track record of an incumbent are not comparable yet. If you need the largest possible demand pool and you are on plain native Android, a mature network may still serve you better on raw fill rate. Evaluate it on your own traffic rather than on a feature list.
Platform #2: ironSource (Unity LevelPlay)
Overview
ironSource, now part of Unity and operating as LevelPlay, is one of the largest mediation and monetization platforms in mobile. Its offerwall sits alongside a substantial rewarded-video and interstitial business, and it brings that demand scale with it.
SDK Support
Android, iOS, Unity and web. Historically strongest in the Unity ecosystem, with a mediation layer that many publishers already run.
Key Features
- Very large advertiser demand pool
- Mediation alongside monetization, so one SDK covers more of the stack
- Deep Unity integration
- Established publisher base and long operating history
Best For
Studios already invested in the Unity ecosystem, and publishers who want a single SDK spanning mediation and rewarded monetization.
Limitations
The integration is heavier than a pure offerwall SDK and it is one of the larger vendors to take on. Reporting is functional rather than real-time in the way a focused platform can be. If you only want an offerwall, this is a lot of platform for the job.
Platform #3: Digital Turbine (formerly Fyber)
Overview
Digital Turbine operates the Fyber brand, with a rewarded video and offerwall business built around premium direct-sold and programmatic demand. It has a long history in the rewarded space and pairs video monetization with offers.
SDK Support
Android and iOS, with a mediation product in the same family.
Key Features
- Rewarded video and offerwall in one integration
- Large premium and direct advertiser demand
- Established mediation product
Best For
Publishers who run rewarded video and offers together and want to reduce the number of SDKs they maintain.
Limitations
The Fyber brand has changed hands and the product naming has shifted, so documentation and SDK references can be inconsistent when you are evaluating. The platform skews toward video-first demand, which is not the same as a broad offer catalog.
Platform #4: Ayet Studios
Overview
Ayet Studios is a mid-sized offer network that has been active in the rewarded offers space for a number of years. It is a reasonable middle ground between a small new entrant and a very large network.
SDK Support
Android and iOS, with additional platform support in its SDK family.
Key Features
- Established in the rewarded offers category
- Competitive eCPM positioning in its core markets
- Developer documentation and integration support
Best For
Publishers who want a proven mid-sized network, and who are not on a cross-platform framework that needs a native wrapper.
Limitations
It does not offer the same cross-platform SDK depth as Perkox, and the reporting tooling is more conventional. If Flutter or React Native support is a requirement, verify the current SDK state before you commit.
Platform #5: Adjoe
Overview
Adjoe is an offerwall and rewarded-ad platform with a strong presence in Android markets, running a mix of its own offerwall products alongside rewarded video inventory.
SDK Support
Android is the primary platform, with iOS support available.
Key Features
- Android-first offerwall and rewarded inventory
- Its own high-frequency app offerwall products
- Presence in emerging and high-volume Android markets
Best For
Android publishers in markets where Adjoe has demand density, especially if your traffic is install-driven rather than survey-driven.
Limitations
Android is the strength and the constraint at the same time – it is not the answer for an iOS-led or cross-platform app. The offer mix skews toward its own products, so the catalog breadth is narrower than a diversified network.
How to Choose: A Short Decision Path
If your app is on Flutter or React Native and you want a native SDK, server-side validation and reporting you can act on, start with Perkox. If you are already deep in the Unity ecosystem and want one SDK for mediation and monetization, evaluate ironSource LevelPlay. If you run rewarded video and offers together, compare Digital Turbine. If you want a proven mid-sized network, look at Ayet Studios. If your traffic is Android install-driven, put Adjoe in the comparison.
Whichever you pick, run the same test on your own traffic. Integrations look similar in a table and behave very differently in production.
Questions Developers Ask About AdGem Alternatives
What is the best alternative to AdGem for cross-platform apps?
For Flutter and React Native apps, Perkox is the strongest match of the five listed here, because it ships native cross-platform SDKs rather than a web-view fallback. ironSource is the alternative to consider if you are already committed to the Unity ecosystem.
Can I run two offerwall networks in the same app?
You can, and it is common practice – you route traffic between them and compare performance. The cost is a second SDK, more attribution complexity, and the need to make sure the two networks do not double-count the same impression. If you do this, keep server-side validation on both sides and keep your reporting separate per network.
Does switching offerwall networks require a new app release?
Almost always, yes. The SDK is compiled into the app, so changing networks means a new binary and a release. That is why the SDK story matters so much when you are comparing: a platform that requires a web-view wrapper or a manual bridge can add weeks to the timeline, because every platform you are evaluating needs a custom implementation rather than a supported one.
How do I compare eCPM fairly across offerwall networks?
Compare on the same traffic, over the same window, with the same placements and the same geo mix. eCPM varies sharply by country and by placement, so a network that looks better in a blended dashboard may simply have more low-tier traffic. Run each network on a slice of your traffic long enough to clear a weekly cycle, and compare revenue per thousand impressions on the placements you actually use.
What should I check about fraud prevention before switching?
Ask specifically how offers are validated. If validation is client-side only, ask what server-side checks exist at all. Then check how quickly a fraudulent install is detected and whether the network credits it back automatically or leaves you to dispute it. The difference determines whether you are monitoring a dashboard or chasing a dispute queue.
Are there AdGem alternatives that support React Native?
Perkox does, with a native React Native SDK. ironSource and Digital Turbine support React Native, but through their broader mediation products rather than an offerwall-first SDK. Ayet Studios and Adjoe are primarily Android and iOS, so React Native apps typically wrap them.
Try the Alternative Built for Cross-Platform Apps
If your app is on Flutter or React Native and the reason you are looking at alternatives is an awkward integration, get the Perkox SDK and compare it on your own traffic. One SDK for Android, iOS, Flutter and React Native, server-side offer validation, and reporting you can act on while campaigns are running.
