Comment créer votre première appli avec Claude Code (gratuit)

Have you ever had an app idea, but thought building it was way too complicated or expensive? Well, what if I told you that you can build your first app with Cloud Code completely for free, >> [music] >> and it's actually a lot easier than you think? Because most people do believe that you need years of coding experience, a computer science degree, or maybe even thousands [music] of dollars to create an app. But here's the thing, that's just not true, not anymore. With AI tools like Cloud Code, you can literally go from having an idea in your head to a working app that people can actually use in just a [music] few hours, not months. So, in this video, I'm going to go ahead and walk you through the entire process step by step to get that accomplished. We're going from idea to building to actually getting your app live and running. I'm going to show you exactly how to do it. I'm going to keep everything simple so that anyone can follow along, and I'll even share the biggest mistakes that beginners make so you can avoid them completely. Plus, I'm also going to show you how to turn your app into something genuinely useful, [music] and maybe even profitable, too. So, that by the end of this video, you're going to have your very own first working app live on the internet, [music] and you're going to realize that building apps isn't this impossible mountain to climb. It's actually pretty straightforward once you know the right approach. And the best part yet, everything that I'm about to show you today in this video costs absolutely nothing to get started. So, if you've ever wanted to bring an app idea to life, then this is your [music] chance to finally make it happen. Now, if you want to master AI tools, and you want to learn how to build profitable mobile apps with AI, SaaS apps, websites, and AI agents, then I've created a complete masterclass that shows you exactly how to do it all step [music] by step. And this masterclass normally costs $299 to join, but since you are watching this video, I'm thankful you can also join completely free. All you got to do is check out that link in the description below to get free access [music] to my masterclass, and you too can start building your own AI-powered business today. So, if you've been looking into building apps with AI, then Claude code is usually one of the first tools that does come up. Now, on paper, it sounds simple. You simply describe what you want, and then the AI generates the code for you. And that makes it seem like you can go straight from idea to finished app just by learning how to prompt it properly, right? [music] But once you actually try working with it directly, then the process becomes a lot more involved. Because Claude [music] code still expects you to understand how applications are built from the ground up. You're working with development environments really, and you're organizing your files, and making sure different parts of the system all connect properly. Also, hosting isn't handled for you here, so you need to set that up yourself, too. And the same goes for databases and user authentication, which then means configuring external services and making sure, again, that all of that everything communicates correctly. And even when the code is generated quickly enough, turning that into something usable does take more time. Getting a stable working app can take weeks or even months, especially if you run into bugs or integration issues. Security is another factor as well that needs attention since [music] it really is your responsibility to make sure that everything is set up correctly and protected. So, at that point, the focus then shifts away from your idea and more towards managing all of those technical pieces behind it. And the process starts to feel less like building an app and more like handling the responsibilities of a full developer. And there's a more [music] practical way to approach this instead because Base 44 can simplify that entire workflow by acting as a sort of wrapper around Claude code. It still runs on Claude as the underlying language model, so the intelligence and the capability, those are still there, but everything around it is structured to help you actually build and launch applications. So that difference shows up right away in how easy it is to use. The platform removes most of that technical friction, which then makes it much faster to go from, again, idea to working app. It's also more reliable for real applications because the core systems are already configured in the background for you. So scaling doesn't require extra setup, either. So you've got hosting, databases, authentication, and deployment that are already built into the platform in Base 44. So you're not assembling those parts manually. So everything is ready to go from the start. Now, working directly with Claude code still requires some technical knowledge to make something actually functional, but using Base 44 shifts that responsibility away from you, so your attention stays on what the app should do rather than how to build it. So the simplest way to look at it is like this. [music] Base 44 gives you Claude's intelligence, but inside a complete app development platform that's already set up and ready to use. >> [music] >> Getting started is usually where most people do get stuck, especially when a platform asks for payment details before you've even tried anything at all. But Base 44 removes that completely because now you can just jump in and you can start building right away without having to enter your credit card, which just so makes it a much easier actual way to test things [music] and see how it works for yourself. Now, what's important here is that the free tier is not limited the way most platforms are because you still get full access to Claude AI. So, there's no drop in quality or capability. Also, that same intelligence that powers advanced [music] builds is available from the start, which means you're not working with a stripped-down version just because you're on a free plan. So, everything around the AI is already set up as well. So, that means the infrastructure is professional-grade, which includes hosting and security that would normally cost a significant amount more if you were setting it up all on your own. So, that entire layer is handled in the background for you [music] and you're no longer dealing with configuration or external services just to get something running. So, the platform itself already covers that full development process >> [music] >> and that means you've got databases, authentication, deployment tools, and even security scanning already built into Baseplate 44. You're not connecting multiple services or figuring out how to make them work together. It's all accessible from the moment you start without paying anything up front. So, when you do build something, it doesn't just stay inside an editor. You can publish it immediately >> [music] >> and your app then goes live without any extra setup at all. There's no separate deployment step or you manually having to configure anything that you have to worry about. So, if you look at everything included, it's honestly just way more than what most paid development platforms offer because you're getting a complete environment already to build real applications from the get-go, of course powered by Claude, without the usual barriers that stop people from even getting started. So, now let's go ahead and build an actual app and I'm doing this entirely inside of Baseplate 44, which again uses Claude as its language model. And for this example, we're going to create a personal task management app, but not just a basic checklist either. The goal here is to build something smarter with features that help users organize their tasks, [music] to track their progress, and manage everything from a clean dashboard. So, before building anything, I am going to use Base 44's plan mode here with Claude Opus 4.7 selected as the main AI model. And this matters because planning first helps Claude understand the app properly before it starts generating the structure. It can ask us questions, it can organize the architecture, it can decide how the features should fit all together. And the prompt I'm using is this: I want to build a personal task management application. The app should include user registration and login, a main dashboard, task creation and management, smart categorization, progress tracking and analytics, and mobile-responsive [music] design. Can you help me plan out the app architecture and features before we start building? And once that's entered in, Base 44 starts mapping out the app for us before even jumping into the build. So, basically here, we're giving it the full direction from the very beginning: user registration and login, task creation and management, smart categorization using Claude's intelligence. And all of that, including progress tracking, analytics, and a responsive layout that works well on mobile. So, this planning stage here is important because it keeps our app from becoming just messy later on. Instead of randomly adding features one by one, now Claude, through Base 44, helps organize the foundation first so that the right features are built in the right order. But here's the thing, and as you've seen here, Base 44 is incredibly powerful, but a lot of people still don't know how to use it properly. They end up building these basic apps that don't make money or websites that can't even convert. So, that's exactly why I created my own complete Base 44 Masterclass. And inside my course, I'm going to show you step-by-step how to build profitable SaaS businesses and high-converting websites, along with, of course, mobile apps, all using AI with zero coding required. You're going to learn how to build SaaS apps that solve real problems and generate recurring revenue. Also, the exact prompts and the strategies that I use to create professional websites in minutes, along with how to clone, yes, clone successful apps and then add your own profitable twist, and my proven system for turning Base 44 projects into actual income streams. So, this is not just theory. I'm going to walk you through those builds. I'm going to show you my exact process, and of course, I'm going to give you the templates and the frameworks that have also helped my students launch their own successful AI-powered businesses. [music] So, again, this masterclass normally costs $299 to join, but only for the people that are watching this video, thank you very much, you can go ahead and join completely free. So, if you're serious, and I hope you are, about building something profitable with AI in 2026, you got to click that link in the description below to join my Base 44 Masterclass. I promise you, your future self will thank you for taking action today instead of just watching another tutorial. All right, so going back to the build now, after confirming that plan, the next step is turning that structure into a working application using Base 44's app building feature, of course, again, powered by Claude. And the moment the build starts, as you can see, everything just begins coming together automatically. The authentication system is already handled natively within Base 44, so user registration and login are set up right from the beginning without any extra steps from our end. So, there's no No to connect external services or manually create login flows. So, as the app is generated here, Base44 builds the core systems in the background. So, the task database is created, the task management functionality is already implemented for us, and the interface along with navigation is designed in real time. [music] Also, user profiles and preferences are set up all behind the scenes as well, which means that the app is being built as a complete [music] product now, not just a visual layout. And this is where Claude's role becomes clear. Base44 uses Claude to understand exactly what we need and then build it intelligently. Everything is defined during that planning stage earlier, and it's translated into a functional application without writing any code manually ourselves. And once the build is complete, as you can see, testing can happen right away. So, we can go through the dashboard here. We can create tasks, interact with the interface, and we can also check how the database responds. So, the live demo happens during this phase, where the app is already usable, and its functionality can be verified in real time. [music] The technical implementation is handled entirely by Claude through Base44, while the focus just stays on how the app performs and whether it does or not deliver the intended experience. So, right now, the app will turn into more than just a basic task manager. Claude's intelligence is now being integrated directly into the features through Base44. So, here's the prompt that I'm going to use. Integrate Claude AI for intelligent features. Add AI-powered task categorization that analyzes task descriptions and suggests appropriate categories automatically. Implement smart reminder timing where AI determines optimal notification schedules based on task priority and due dates. Create a natural language task input where users can type tasks [music] in plain English and the AI extracts the details. Add an analytics dashboard where AI provides productivity insights and suggestions based [music] on task completion patterns. So, all of that prompt, all of those capabilities, they're added through a single prompt only. Claude analyzes those task descriptions and automatically suggests the most relevant categories, thus removing the need for us to organize everything manually. It also handles reminder timing, which is great, by looking at task priority and the deadlines, then choosing when notifications should be sent for the best timing. Natural language input also makes the app a lot easier to use here, since tasks [music] can just be written in plain English, while Claude then extracts and structures the details behind the scenes. The analytics dashboard here becomes more meaningful, as well, since Claude can now detect [music] those patterns in our completed tasks and also provide insights along with suggestions to improve our own productivity. And after running the prompt, these features can now be tested directly inside the app to see how each one does behave. So, base44 is not just helping build the app at this point, [music] it's using Claude to actively enhance how the app works for the user. [music] Our final step is turning the app into something more polished and ready for real users. So, we'll focus on refining the design, improving the user experience, and of course, making sure that everything works smoothly across devices. So, here's the prompt I'm going to use. Polish the task management app for production. Customize the branding with a professional color scheme. Add a custom logo placeholder and refine the UI design with smooth transitions and animations. Ensure the mobile experience is perfect with touch optimized controls, [music] responsive layouts that work on all screen sizes, and mobile-friendly navigation. Add loading states for all actions, success, error notifications for user feedback, and improve the overall user experience with polished interactions. Make sure all features work seamlessly on both desktop and mobile devices. And after running that prompt, the app now gets a more professional look. As you can see, branding is applied through colors and visual adjustments. There are transitions and animations added, and small details like loading states and notifications make our app just a lot more complete feeling. Mobile optimization is also handled here, making sure that everything works properly on different screen sizes with smooth navigation and still touch-friendly controls. >> [music] >> Testing is part of this process as well, because Base 44 has built-in tools that allow you to go through the app. So, we'll go ahead and check features and make sure that everything runs as expected without needing external tools. [music] And once everything is ready, then the app can now be published directly. [music] There's no separate setup for hosting or deployment because as soon as you click publish here, the app then goes live and becomes accessible through a shareable link. So, you can send that link to others and make sure that the app is public for anyone to use. So, all the technical parts like the hosting, the security, and the deployment, those are already handled automatically in the background for you. So, what started as a simple build is now a production-ready app without you needing to manage any other infrastructure. Now, if you've ever looked into building an app the traditional way, you've probably seen how quickly the costs and the complexity start adding up before you even get something working. Now, Base44's free tier already includes full Claude AI integration, which means now you're working with the same level of intelligence that you would get from paid platforms. And it's not limited or restricted, either. On top of that, it functions as a complete app development platform. So, again, you're not missing any core pieces needed [music] to build real applications. Along with that, we've got hosting and infrastructure that are already included. So, again, there's no need to pay for external services just to get your app online. User authentication [music] is built in, which means login systems are already handled for you without connecting tools like, say, Auth0. Database functionality is also part of the whole platform, allowing you to store and manage data directly inside of Base44. Of course, mobile optimization is handled automatically. So, apps do work properly across different screen sizes from desktop [music] to mobile without any extra adjustments. Deployment happens instantly. So, once the app is ready, you can just go live with a single action. And then, the end result really just matches what you would expect from professional development tools. And all of this is available without a credit card, which makes it one of the most accessible ways to really start building AI-powered applications. Now, traditional development works very differently, right? Hosting alone can cost anywhere from 50 bucks to $200 [music] per month. Databases add another 20 to $100 monthly through services like Superbase or Firebase. And then, authentication systems can cost an additional 30 to $150 per month [music] using tools like Auth0. So, before even launching anything, the total can easily reach $100 to $450 every month. So, time is also another factor, too, because learning how to connect all these systems [music] properly does take months, and even then, the setup process can be incredibly complex. Managing multiple services means ongoing maintenance, and of course, mistakes in configuration can lead to a security vulnerabilities. There's also no built-in AI capability from the get-go, so additional tools or subscriptions are required just to match what Base 44 already provides. So, the difference really comes down to what you're actually spending your time and money on because traditional development really just focuses heavily on infrastructure and setup, while Base 44 removes that layer for you completely and gives you a working system from the very start. You've now seen how an idea can go from a simple concept to a fully working app that is live and usable. And the entire process stays focused on what you want to build without really you getting pulled into [music] any technical setup, infrastructure, or any other complicated workflows. Of course, Claude handles the logic, and then Base 44 handles the system around it, [music] and everything just comes together in one place. So, if building apps has been something that you've been putting off, then this makes [music] it a lot more practical to actually try. So, start small, test out your ideas, and then build something that people can use. And that's it for this one. Thanks for investing your time with me today. I'll see you on the next one.
