Introduction: The Dilemma of Choosing AI Tools

AI coding tools are currently in an era of fierce competition. ChatGPT, Claude, Cursor… Many people are probably wondering, "Which one should I ultimately use?"

I have used all of these tools in practice, and my conclusion is that for those who find "even environment setup bothersome" or "just want to create something that works," Genspark is the only choice.

Why do I, a developer, recommend Genspark? I will explain the reasons based on actual development records.

The Decisive Difference: The "Sandbox (Execution Environment)"

ChatGPT writes excellent code, but you need to prepare the environment (local PC or server) to execute that code yourself. Cursor is the strongest editor, but it requires Git and Node.js setup.

Genspark's greatest strength lies in its "sandbox" feature, which allows you to execute code immediately just with a browser.

Writing code and running code are completely different things. Genspark can complete both of these within a single screen.

💡 For more details, refer to this practical article:

Understanding the Difference Between Code Generation and Code Execution with Genspark

※This article technically explains the difference in the process where AI not only writes code but also actually runs it and fixes errors.

"Autonomous Agents" Handle Even Bug Fixing

Simply outputting code is possible with other AIs. However, Genspark's autonomous agents handle the entire process of "if an error occurs, reading the logs, automatically fixing it, and re-executing."

In fact, I utilized this feature to refactor 20,000 lines of legacy code that had no documentation or tests. Tasks too risky for humans to handle can be safely proceeded with AI.

Frankly, Can It Be Used for Full-scale Development?

You might think, "It only runs simple Python scripts, right?" However, I am developing and operating full-scale web applications using Next.js and Cloudflare Workers.

Of course, there are frontend-specific quirks and pitfalls when integrating with Cloudflare. However, knowing how to circumvent them dramatically improves development speed.

For those who have experienced frustration with environment setup, or who have ideas but lacked the time to bring them to fruition.

First, try to bring your ideas to life with Genspark's "Super Chat." The joy of seeing code generated before your eyes and coming to life as an application cannot be experienced with other tools.

8. [February 2026 Update] Genspark as a Development Tool: Real Experience Building a 22,000-Line App on Smartphone

After publishing this article, many readers requested "comparison with Claude Code." Here, I'll introduce Genspark's capabilities as a development tool based on real experience.

8.1 The Biggest Differentiator: Full-Scale Development on Smartphone Only

I actually developed a 22,000-line web application in 6 days using only a smartphone. This is Genspark's greatest strength.

Development Environment Details

• Device: Smartphone only (no PC used)
• Development Period: 6 days
• Code Size: Approximately 22,000 lines
• Development Locations: Commuter train, cafe, home sofa, bed before sleep

On the other hand, Claude Code is a CLI (Command Line Interface) tool, so PC + terminal environment is essential. You cannot immediately implement ideas that come to mind while out and about.

8.2 Comparison Between Genspark and Claude Code

Comparison Item	Genspark	Claude Code
Development Environment	Smartphone/Tablet/PC	PC (terminal required)
Pricing	Free tier available	$20-200/month (usage-based)
Interface	Browser GUI	CLI (command line)
Beginner-Friendly	◎ Visually intuitive	△ Terminal knowledge required
Setup	Not required (browser only)	Required (installation/configuration)
Real-time Search	◎ Built-in standard	○ Possible via MCP
Context Management	△ Requires attention	◎ Excellent
Professional Features	○ Basic features	◎ Advanced development features

8.3 What I Learned from Smartphone Development

✅ Advantages

Travel Time Became Development Time

30 minutes on the commuter train, 15 minutes at a cafe during lunch break, 10 minutes before bed—all these fragmented times became development time. No need to carry a PC, allowing development anywhere.

Immediate Implementation of Ideas

The moment I thought "it would be nice to have this feature," I could start coding on the spot. No need to start up a PC.

No Setup Required

With just a browser, I could start development immediately. No environment setup or tool installation was necessary.

⚠️ Points to Note

Screen Size Limitations

Compared to a PC, the amount of code visible at once is limited. However, using an external keyboard and tablet significantly improves this.

Context Management

As explained in a previous article, periodic chat screen transitions are necessary for long work sessions. This is one of Genspark's weaknesses.

Input Speed

Input becomes slower with a smartphone's software keyboard. Using a Bluetooth external keyboard is strongly recommended.

8.4 Which Should You Choose?

8.5 Actually, You Can Use Both

In my actual usage, I sometimes use both in combination:

• On the go/while traveling: Prototype creation and idea implementation with Genspark
• At home/office: Full-scale implementation with Claude Code (or ChatGPT)

This hybrid strategy enables a flexible development style unconstrained by time and location.

8.6 Summary: Smartphone Development as an Option

The conventional wisdom that "full-scale development requires a PC" is being overturned by the evolution of AI tools.

The fact that I could actually create a 22,000-line app using only a smartphone demonstrates the possibility of new development styles.

Claude Code is also an excellent tool, but Genspark's strength of "being able to develop anytime, anywhere" should have significant value for many developers.

Especially for those engaged in side businesses or personal development with "limited time," I recommend trying Genspark first.
