19 Mistakes to Avoid When Choosing an App Builder

Choosing the right app builder can feel like navigating a minefield, especially if you're a solo founder or building a side project. With so many options available, it’s easy to make costly mistakes that can derail your project before it even gets off the ground. In 2026, as the landscape of app builders continues to evolve, avoiding common pitfalls is more crucial than ever. Here’s a rundown of the mistakes we’ve encountered and learned from, along with actionable insights to help you choose wisely.

1. Ignoring Your Specific Needs

Before you start looking at app builders, take a step back and define what you actually need. Are you building a simple MVP or a complex application? Some builders excel in specific areas but fall short in others. For instance, if you're looking for a robust e-commerce solution, choosing a builder focused on simple forms can lead to frustration.

Our Take:

We spent weeks evaluating platforms that didn’t align with our project goals. Define your requirements first: features, scalability, and budget.

2. Overlooking Customization Options

Many app builders offer templates that can get you started quickly, but if you don’t consider how customizable these templates are, you might end up with a cookie-cutter app that doesn’t meet your brand’s needs.

Limitations:

Some platforms, like Wix, offer limited customization beyond their templates. If unique branding is essential, consider builders like Bubble or Adalo.

3. Not Evaluating Pricing Structures

Pricing can be deceptive. Many app builders advertise low starting prices but have hidden fees as you scale. Always read the fine print and consider the costs associated with hosting, additional features, or user limits.

Pricing Breakdown:

| App Builder | Pricing | Best For | Limitations | Our Take | |-------------|---------|----------|-------------|----------| | Bubble | Free tier + $29/mo for pro | Complex web apps | Steep learning curve | We use this for web apps but it takes time to master. | | Adalo | Free tier + $50/mo for pro | Mobile apps | Limited integrations | We don't use this due to limited backend capabilities. | | Glide | Free tier + $25/mo for pro | Simple mobile apps | Limited functionality | Great for quick prototypes, but not for complex apps. | | AppGyver | Free | No-code apps | Limited support | Perfect for indie projects, but community is small. | | Thunkable | Free tier + $20/mo for pro | Mobile apps | Performance issues | We like its ease of use but it's not for heavy apps. | | Appy Pie | $18/mo | Simple apps | Limited customization | We avoid it for serious projects due to basic features. |

4. Failing to Test the Platform

Many builders offer free trials or demo versions. Don’t skip this step! Testing the platform will give you a feel for its usability, performance, and whether it meets your needs.

Expected Output:

You should be able to create a basic app in under an hour during your trial. If not, reconsider your choice.

5. Neglecting Future Scalability

What works for a small user base may not work as you grow. Make sure your chosen app builder can scale with your needs. Some platforms may offer basic features but can’t handle higher traffic or more complex functionalities.

Our Experience:

We initially chose a builder that worked well for our first 100 users but crashed when we hit 1,000. Make sure to ask about user limits.

6. Ignoring Community and Support

A vibrant community and strong support can be a lifesaver when you hit roadblocks. Look for platforms that offer forums, tutorials, and responsive customer service.

Our Take:

We often rely on community forums for troubleshooting. Platforms like Bubble have robust communities, while others may leave you stranded.

7. Overvaluing Aesthetics Over Functionality

While a sleek interface is appealing, functionality should always come first. Make sure the builder can deliver the features you need before getting lost in design options.

Limitations:

A beautiful app that crashes frequently isn’t worth it. Focus on reliability first, then design.

8. Not Considering Integration Capabilities

If you plan to connect your app to other tools or services, ensure your builder has the necessary integrations. Some platforms are notoriously restrictive in this regard.

Pricing Comparison:

| App Builder | Integrations | Limitations | |-------------|--------------|-------------| | Bubble | 100+ | Some require paid plans to access | | Adalo | 30+ | Limited API access | | Zapier | 2000+ | Not an app builder but essential for integrations |

9. Skipping Security Features

Security should never be an afterthought. Ensure that the platform you choose has built-in security features, especially if you’re handling sensitive user data.

Our Take:

We learned the hard way when an app we built had minimal security, leading to a data breach scare. Always prioritize user safety.

10. Choosing Based on Trends

Just because a platform is popular doesn’t mean it’s right for you. Trends come and go; your app’s needs should dictate your choice.

Our Experience:

We’ve seen many builders rise and fall. Always make decisions based on your specific project requirements, not hype.

11. Underestimating Learning Curves

Some app builders have steep learning curves that can delay your launch. Be realistic about how much time you can invest in learning a new tool.

Expected Time:

If you’re not familiar with a platform, expect to spend at least 10-15 hours getting comfortable with it.

12. Not Planning for User Experience

User experience (UX) is critical. Ensure that the app builder allows you to create an intuitive and user-friendly interface.

Limitations:

Some builders prioritize aesthetics over usability, leading to apps that look good but are hard to navigate.

13. Forgetting About Mobile Responsiveness

In 2026, most users are on mobile devices. Make sure your app builder can create responsive designs that work well on all screen sizes.

Our Take:

We’ve had to redesign apps that weren’t mobile-friendly. Check mobile previews before committing.

14. Overlooking Analytics and Reporting

Data-driven decisions are key to growth. Choose an app builder that offers built-in analytics or easy integration with analytics tools.

Our Experience:

We initially launched without analytics, which made it hard to track user engagement. Don’t make the same mistake.

15. Not Considering Offline Capabilities

If your app needs to function offline, ensure your builder supports this feature. Many don’t, which can limit your app’s usability.

Limitations:

Platforms like Glide don’t support offline capabilities, which can be a dealbreaker for some use cases.

16. Rushing the Decision

Take your time to evaluate your options. Rushing can lead to overlooking critical features or costs.

Our Take:

We once chose a builder in haste and ended up switching later, wasting time and resources. Slow down and do your homework.

17. Ignoring User Feedback

If you have a small user base, get their feedback on usability and features. Their insights can guide your decision on which builder to choose.

Our Experience:

We’ve made changes based on user feedback that significantly improved our app’s functionality and satisfaction.

18. Not Considering Multi-Platform Support

If you plan to launch on both iOS and Android, ensure your app builder can handle multi-platform development seamlessly.

Limitations:

Some builders are strictly web-based or only cater to one platform, limiting your reach.

19. Forgetting to Review Terms of Service

Always read the terms of service and understand what you’re agreeing to. Some platforms have restrictive clauses that may not align with your business model.

Our Take:

We’ve encountered unexpected fees and restrictions that impacted our app’s growth. Don’t skip this crucial step.

Conclusion

Choosing the right app builder is a significant decision that can affect your project’s success. Start by clearly defining your needs, evaluating pricing structures, and testing platforms. Avoid the common pitfalls outlined above to ensure you make an informed choice.

To kickstart your journey, I recommend starting with a platform that aligns with your specific goals and offers flexibility for growth. For most indie hackers, Bubble or Adalo can be great starting points, depending on your app's complexity.
