Building an app with AI seems like a futuristic dream, but it has become a reality with tools like Base44.
This AI app builder was recently acquired by Wix for a whopping $80 million, signaling its potential in the no-code development space.
But how does Base44 stack up against competitors like Lovable and Bolt?
Let's dive into this tutorial for Base44 and see what it can really do.
Building a Podcast Finder App with Base44 AI App Builder
To put Base44 through its paces, I decided to build a podcast finder app.
The initial prompt was simple: create an app that helps users discover new podcasts based on their interests and listening habits.
Base44 offers a unique feature called "styling instructions," which allows you to specify design preferences. I chose a glassmorphism style to give the app a modern look.
The AI quickly generated a high-level plan and began working through a task list. One of Base44's strengths is its all-in-one approach - the database, authentication, and even LLM calls are built directly into the platform. This integration can be both helpful and potentially limiting, depending on your needs.

Overcoming Design Challenges
The first version of the app had some readability issues due to light text on a light background. After providing feedback and a screenshot, Base44 was able to adjust the design.
his iterative process highlights the importance of clear communication with AI tools.
Exploring Base44's Workspace and Data Management
Base44's workspace feature provides a comprehensive view of your app's data and settings.
The workspace makes it easy to manage your app's backend without leaving the Base44 platform.
This all-in-one solution will be appealing to many. With this in mind, let's look at how to get everything set up now.
Integrating Real Podcast Data Using Base44's API Connection
To make the app more useful, I wanted to pull in real podcast data from an API. This process revealed some important considerations about Base44:
Enabling Backend Functions
To use API connections, you need to enable backend functions in Base44.
This feature requires upgrading to the Builder plan, which costs $50 per month. It's worth noting that some competitors offer API integration without additional fees.
Connecting to the Podcast Index API
Base44 suggested using the Podcast Index API, a free and open podcast database. The AI was able to research and implement the API connection, showcasing its ability to adapt to specific requirements.
Troubleshooting API Integration
We encountered some errors during the API integration process. This highlighted the importance of persistence when working with AI tools. Through back-and-forth communication and debugging, we were eventually able to successfully connect to the API and display real podcast data in the app.

Implementing User Authentication in Base44
Adding user authentication to the app was surprisingly straightforward with Base44. Here's what I did:
Created a landing page for logged-out users
Built login/logout functionality
Tested user registration and login process
Managed users in Base44's workspace
The AI was able to implement these features quickly, demonstrating Base44's strength in handling common app functionalities.

Monetization Options and Advanced Features in Base44
While I didn't implement monetization in this demo, Base44 does offer options for adding payment functionality to your app:
Stripe integration for payments
Backend functions for handling transactions
Domain management for custom branding
It's important to note that these advanced features require the Builder plan, which may impact your decision depending on your budget and needs.
Base44 AI App Builder: Pros and Cons
Pros:
All-in-one platform with integrated database and authentication
Quick app generation from simple prompts
Ability to connect to external APIs
Built-in user management and analytics
Cons:
Advanced features require a more expensive plan
Some limitations compared to traditional development
Occasional design issues that require manual correction
Base44 shows promise as an AI-powered app development tool. Its ability to quickly generate functional apps from simple prompts is impressive. However, the need to upgrade to a more expensive plan for advanced features like API integration may be a drawback for some users.
Compared to other AI app builders like Lovable or Bolt, Base44's all-in-one approach could be an advantage or a limitation, depending on your specific needs. It's worth considering your project requirements and budget when deciding which tool to use.
For those looking to quickly prototype ideas or build simple apps without coding knowledge, Base44 could be a valuable tool. However, for more complex projects or those requiring extensive customization, you might find yourself bumping up against the limitations of the platform.
Ultimately, the best way to determine if Base44 is right for you is to try it out yourself. Start with a simple project and see how it handles your specific use case.
