Building a mobile app today isn’t just about great ideas, it’s about speed, efficiency, and execution. Traditional coding frameworks, such as the MERN stack (MongoDB, Express, React, Node.js), give developers complete control, but they also require significant time, resources, and technical expertise. From setting up the backend to managing APIs and UI logic, even a simple app can take weeks before it’s ready for testing.
Then there’s Thunkable, a no-code platform that promises to turn your app ideas into fully functional mobile applications without writing a single line of code. Sounds too good to be true, right? That’s exactly what our team wanted to find out.
So, we decided to put Thunkable to the test.
Our in-house MERN Stack developer, who usually lives and breathes JavaScript, took a break from coding syntax and explored the no-code world to see if Thunkable could actually deliver. Could a drag-and-drop builder match the speed and flexibility of traditional development?
Could it build a usable app quickly?
In this experiment, we’ll walk you through everything: the setup, the process, the results, and an honest verdict from a developer’s perspective.
Our development team has spent years working with the MERN stack, crafting apps that are scalable, dynamic, and fully customizable. But while the power of MERN is undeniable, there’s one major trade-off: time.
A typical project goes through multiple layers, setting up the server, building REST APIs, managing states, connecting databases, handling UI logic, and finally, testing on different devices. Even a seemingly simple mobile app can require several weeks before it’s ready for launch.
That’s where Thunkable caught our attention. As a no-code app builder, it claims to help users, developers, and non-developers alike create cross-platform mobile applications visually, without writing code.
With its drag-and-drop interface and logic blocks, it looked like an appealing shortcut to get from idea → prototype → functional app much faster.
But we didn’t want marketing claims, we wanted real evidence. So we designed a test. Our goal was to build a fully functional mobile app prototype using Thunkable and compare it against our regular MERN stack process. The app idea we chose was simple but realistic — a Gifting App, featuring:
We gave our developer a clear challenge:
“You have three days to build this Gifting App entirely using Thunkable. No coding, no external frameworks, just the tools Thunkable provides. Let’s see what’s possible.”
This wasn’t about comparing no-code vs code to crown a winner. It was about exploring whether Thunkable could genuinely deliver a functional, user-ready app in record time and whether a seasoned developer could adapt to this new, visual approach without missing the power of traditional coding.
Before diving into development, we wanted this test to feel as close to a real-world project as possible. So, we outlined a clear structure, including the app’s scope, the metrics for success, and the workflow our developer would follow from start to finish.
To evaluate whether Thunkable can help a professional MERN stack developer build a fully functional, cross-platform Gifting App, faster and easier than traditional development methods, without compromising user experience.
The entire process was limited to three days:
The Gifting App needed to include:
Our MERN stack developer wasn’t new to app logic, but this was their first full project using a no-code tool. The goal was not to replace coding skills but to see how quickly someone with coding experience could adapt to a drag-and-drop development mindset and whether it actually saved time in the end.
By setting these boundaries, we ensured the experiment stayed fair, focused, and result-driven.
Once the framework of our experiment was in place, it was time to roll up our sleeves and start building. Our MERN stack developer logged into Thunkable with a curious mix of skepticism and excitement. What followed over the next three days was a detailed journey, one that reshaped how we view app creation altogether.
Setting up Thunkable was surprisingly simple. Within minutes, our developer had an active workspace and access to the drag-and-drop studio. The dashboard offered three clear sections:
Unlike traditional setups (installing Node.js, managing React dependencies, connecting MongoDB, etc.), Thunkable’s process was plug-and-play, no installations and no configuration headaches.
The first impression? It feels like designing an app inside Figma but with working logic.
The developer started by sketching out the Gifting App’s screen flow:
The clean, visual interface immediately made it easier to map the user journey.
In MERN projects, UI design means writing JSX, styling with CSS, and debugging layout responsiveness. In Thunkable, it was all drag-and-drop.
Our developer quickly added:
The customization options were solid color palettes, rounded corners, shadows, fonts and everything editable through property panels.
Our developer saying:
“I was able to design a fully functional four-screen layout in less than 90 minutes, something that would take about 4–5 hours in React Native.
However, the developer also noticed a limitation: Thunkable’s layout behaves differently on different devices, so fine-tuning spacing and scaling required multiple previews to get it just right.
This is where curiosity peaked. Could a no-code platform truly replace conditional logic and JavaScript functions? Thunkable’s block-based logic system worked similarly to coding but visually. Each action (like button clicks, data fetches, or screen navigations) was represented as a block that could be snapped together like puzzle pieces.
Here’s what the developer did:
Honestly, it felt like visual JavaScript. Once I understood how logic blocks connected, everything clicked, pun intended. By the end of Day 2, all screens were interactive. The developer could pick a gift, write a message, and generate a shareable link preview, all without a single line of code.
Thunkable’s live testing was one of its strongest features. Using the Thunkable Live app, the developer previewed the project instantly on both Android and iOS.
Each change in the editor updated in real time on mobile, eliminating the long compile times that React Native developers usually face.
During testing, we evaluated:
The performance was smooth for small datasets, though large Airtable responses occasionally caused slight lags expected for no-code platforms relying on external APIs. The live testing feature is addictive. Seeing instant results makes debugging feel effortless.
Finally, it was time to wrap up the app for distribution. Thunkable offers one-click publishing options, along with the ability to generate standalone APK or iOS test builds.
The developer exported the final version and ran it on a real Android phone, it worked seamlessly. The shareable links, image displays, and personalized messages all functioned as expected.
I’ve spent hours configuring build tools before. Here, I literally downloaded a working app in minutes.
While the platform handled deployment smoothly, there were some trade-offs, such as limited control over advanced animations and backend-level customization. But for a 3-day prototype, the results were impressive.
After three days of building, testing, and refining the Gifting App, it was time to step back and evaluate the results. We didn’t just look at whether the app worked, we wanted to understand how well it worked compared to a typical coded approach.
Our evaluation focused on five core aspects: speed, ease of use, functionality, flexibility, and performance.
This was where Thunkable shined the brightest.
A similar app in the MERN stack (React for UI, Node + MongoDB for backend) would typically require:
That’s roughly 4–5 days of active development, not counting debugging.
Thunkable reduced that timeline drastically.
“From design to deployment, it took me around 14 hours total to get a fully working prototype complete with database integration and sharing features.”
This speed gain came mainly from skipping repetitive setup steps and using pre-built UI and logic components.
Thunkable’s user interface was intuitive even for a seasoned developer. The drag-and-drop layout, clear navigation tabs, and real-time previews helped our developer build confidently without external documentation overload.
However, adapting to a visual development mindset did take a few hours. Developers who are used to typing out logic may initially find the block system limiting, but once understood, it feels natural and efficient.
“The learning curve is steep for the first two hours, then it just flows.”
Our Gifting App included all planned core features:
All of these were achieved without writing a single JavaScript function.
What impressed us most was how smoothly the data integration worked. Thunkable connected to Airtable API with minimal setup, just paste the API key and table name, and it instantly pulled the data into the app.
This was the area where Thunkable met its limitations.
While it’s powerful for prototyping and lightweight app logic, our developer noted:
That said, Thunkable wasn’t built to compete with full-stack frameworks, it was designed to simplify and speed up creation, and it does that impressively well
Once published, the app performed smoothly across devices.
Overall, the performance was stable and user-ready, good enough for MVPs or client demos.
“If I had to pitch an idea to a client tomorrow, Thunkable could get me there tonight.”
Thunkable proved that it can empower even experienced developers to prototype, iterate, and launch ideas faster than ever before.
The 3-day gifting app challenge revealed a key insight:
Thunkable doesn’t replace developers, it amplifies them. By removing repetitive setup tasks and letting creativity take the lead, Thunkable bridges the gap between concept and execution making it ideal for MVPs, startups, and rapid proof-of-concept projects.
After spending three full days inside Thunkable, our developer walked away with more appreciation than skepticism. The experience challenged the traditional mindset of real development requires real code and replaced it with “real results don’t always need code.”
Here’s what stood out the most:
Thunkable’s block-based logic wasn’t just a gimmick, it worked intuitively.
For a developer who’s used to typing conditions and functions manually, the drag-and-drop logic felt surprisingly structured. Each block clearly represented a real coding concept: variables, loops, conditions, and event triggers.
“Once I stopped thinking like a coder and started thinking visually, it felt like I was literally building my logic with my hands.”
The biggest plus was error prevention, no syntax mistakes, no missing semicolons, and no undefined variables. Just clear, visual cause-and-effect logic.
Testing an app instantly on a mobile device without compiling or waiting for builds was a game-changer.
Thunkable’s Live App allowed the developer to see every design tweak, logic change, or database update appear in real time. This dramatically reduced the time spent switching between editor, emulator, and console.
“I could see how each button behaved instantly on my phone. That kind of feedback loop keeps you in a creative flow, something coding often interrupts.”
Thunkable made connecting APIs and databases almost effortless. In the gifting app, our developer used Airtable as a data source and the setup took less than 5 minutes. Simply paste an API key, map columns, and data appears like magic. Other integrations like Google Sheets, Firebase, and Web APIs were also available — perfect for lightweight backend logic.
“Normally, connecting an API in React involves Axios calls and CORS configs. In Thunkable, it’s just connect and use.”
Thunkable automatically builds for both Android and iOS, no platform-specific configuration required.
The ability to publish with one click (and test instantly on both platforms) removed the usual headache of environment setups and version conflicts that most developers deal with.
“It felt unreal to have an iOS and Android version ready the same day — that’s something you rarely say as a developer.”
Perhaps the biggest win was speed. Thunkable allows teams to visualize an idea, test it, and share it within hours instead of weeks. For agencies, startups, or freelancers, this means faster client approvals and shorter development cycles.
“If I had a startup idea tonight, I could demo it tomorrow morning, that’s how fast Thunkable is.”
No platform is perfect and also Thunkable is, despite its strengths, has a few areas that could use refinement:
“It’s powerful for quick builds but for large-scale apps, you start to miss the precision of actual code.”
Despite these minor trade-offs, the platform’s ease and speed still outweigh its constraints for most use cases.
By the end of our 3-day challenge, one thing was clear, Thunkable delivers on its promise. It doesn’t just make app creation faster; it changes how you think about building apps altogether.
Our MERN Stack developer, someone used to dealing with servers, APIs, and long build pipelines, admitted that Thunkable cut the development time by more than half while still delivering a polished, user-ready app.
“Thunkable won’t replace traditional coding but it definitely replaces the long waiting time between idea and execution.”
From onboarding to publishing, everything felt designed for speed, simplicity, and creativity. The gifting app worked across Android and iOS, complete with dynamic data, clean navigation, and personalized features, all without a single line of JavaScript.
