Building an app is exciting. Handling payments? Not always. In-app billing can feel complex, technical, and a little scary. Many startups begin with RevenueCat. It is popular. It is powerful. But it is not the only option. Some companies want more control. Others want lower fees. And some just want something simpler.
TLDR: RevenueCat is great, but it is not your only choice. Startups often compare it with tools like Stripe, Paddle, Qonversion, Glassfy, and Adapty. Each has different pricing models, features, and levels of control. The best choice depends on your team size, app type, and growth plans.
Let’s break it down in plain English. No jargon. No fluff. Just the tools startups evaluate when shopping for an in-app billing platform.
Why Look Beyond RevenueCat?
RevenueCat makes subscription management easier. It connects to Apple App Store and Google Play. It handles receipt validation. It tracks subscriptions. It offers dashboards.
But startups sometimes hesitate because:
- They want lower platform fees.
- They need more custom backend control.
- They prefer an all-in-one merchant of record.
- They want advanced analytics baked in.
- They want tighter web and mobile billing sync.
So what are the alternatives?
1. Stripe
Stripe is a giant in online payments. It is not built only for apps. It powers payments everywhere.
Best for: Startups wanting full control and web-first billing.
Stripe lets you:
- Manage subscriptions
- Create custom pricing tiers
- Handle coupons and trials
- Build your own billing logic
- Sync web and mobile payments
But here is the catch. Stripe does not magically bypass Apple and Google fees for in-app purchases. If you sell digital goods inside iOS apps, you still must use Apple’s system.
Stripe shines for SaaS tools. Or hybrid apps with web-first experiences.
Pros:
- Extremely flexible
- Developer-friendly APIs
- Global payment support
Cons:
- More engineering effort
- No native mobile SDK subscription magic like RevenueCat
2. Paddle
Paddle is very interesting. It acts as a merchant of record. That means Paddle handles taxes, compliance, and payments for you.
Startups love this. Especially small teams without a finance department.
Best for: SaaS startups selling globally.
Paddle offers:
- Subscription management
- Tax handling (VAT included)
- Fraud protection
- Web checkout tools
- Analytics
This can reduce operational headaches. Big time.
But again, native mobile in-app purchases still require Apple and Google rules. Paddle works better for web SaaS subscriptions.
Pros:
- Taxes handled automatically
- Simple pricing model
- All-in-one platform
Cons:
- Less flexible than raw Stripe
- Not focused purely on mobile apps
3. Qonversion
Qonversion feels closer to RevenueCat. It is built specifically for mobile subscription apps.
Best for: Subscription-first mobile apps.
It provides:
- Cross-platform subscription tracking
- Analytics
- A/B testing tools
- Real-time data sync
- Push integrations
One thing startups like? Built-in growth tools. It is not just billing. It is revenue optimization.
Qonversion focuses heavily on metrics. Think churn rate. Trials. Conversion funnels.
Pros:
- Subscription analytics built-in
- Easy mobile SDK integration
- Marketing-friendly dashboards
Cons:
- Still layered on Apple and Google billing
- Less customizable than building your own backend
4. Glassfy
Glassfy is another mobile-first subscription platform. Smaller than RevenueCat. But growing.
Best for: Indie developers and small startups.
It includes:
- Subscription infrastructure
- Purchase validation
- Cross-platform sync
- Light analytics
Glassfy markets itself as simple and affordable.
Sometimes startups pick it because pricing feels friendlier at early stages.
Pros:
- Clean integration
- Simple dashboards
- Competitive pricing
Cons:
- Fewer advanced features
- Smaller ecosystem
5. Adapty
Adapty mixes subscription management with growth tools. It competes directly with RevenueCat.
Best for: Apps focused on increasing subscription conversions.
Features include:
- In-app paywall builder
- A/B testing
- Subscription analytics
- Server-side receipt validation
Some startups love the built-in paywall tools. No need to design everything from scratch.
This saves design and engineering hours.
Pros:
- Paywall experiments
- Strong analytics
- Mobile-first focus
Cons:
- Another layer of dependency
- Costs grow as you scale
6. Building It Yourself
It sounds bold. But some startups do it.
They build their own billing backend.
Why?
- Full control
- No third-party dependency
- Custom reporting
- Potential long-term savings
This approach requires:
- Backend engineers
- Deep knowledge of Apple and Google APIs
- Compliance management
- Ongoing maintenance
It is not for early-stage teams with two developers.
But at scale? It can make sense.
Quick Comparison Chart
| Platform | Best For | Mobile Focus | Analytics | Merchant of Record | Customization |
|---|---|---|---|---|---|
| RevenueCat | General subscription apps | High | Moderate | No | Medium |
| Stripe | Web SaaS | Low | Basic | No | Very High |
| Paddle | Global SaaS | Low | Moderate | Yes | Medium |
| Qonversion | Mobile subscriptions | High | Strong | No | Medium |
| Glassfy | Indie apps | High | Light | No | Medium |
| Adapty | Conversion focused apps | High | Strong | No | Medium |
How Startups Actually Decide
The decision is not just about features.
It comes down to three big questions:
1. How technical is your team?
If you have backend experts, Stripe or custom builds look attractive.
If you want plug-and-play, tools like Qonversion or Adapty win.
2. Where do users pay?
If mostly inside iOS and Android apps, you need strong mobile SDKs.
If mostly on web, merchant-of-record tools look better.
3. Are you optimizing for speed or control?
Speed? Use a managed platform.
Control? Build more in-house.
Hidden Costs to Consider
Fees are obvious. Hidden costs are not.
Think about:
- Engineering time
- Maintenance work
- Subscription migration complexity
- Analytics tool stacking
- Tax compliance effort
A cheaper tool may cost more in developer hours.
An expensive tool may save months of work.
Time is money. Especially in startups.
The Fun Truth
There is no perfect answer.
Every billing system is a trade-off.
RevenueCat is popular for a reason. It sits comfortably in the middle. Good balance. Good integrations.
But startups exploring alternatives are not crazy. They are strategic.
- Some want deeper analytics.
- Some want tax handling included.
- Some want total ownership.
- Some just want a better deal.
The good news? The ecosystem is strong. There are more choices than ever.
Final Thoughts
In-app billing is not glamorous. But it powers everything.
If you get it wrong, you leak revenue.
If you get it right, subscriptions grow smoothly.
Startups evaluating alternatives to RevenueCat usually look at Stripe, Paddle, Qonversion, Glassfy, and Adapty first. Each serves a slightly different mission.
The smartest move?
Map your revenue model first.
Map your team skills second.
Then choose the platform.
Not the other way around.
Because billing is not just about collecting money.
It is about building a system that grows with you.
