A Mobile-Friendly HTML Code Editor and Preview Tool
NOTEI’m Yang Qing, an internet architect focused on building scalable AI automation systems and intelligent agent engineering.
Here, we don’t discuss concepts—we build truly executable AI systems.
Use Cases
Anyone who has used DeepSeek knows that HTML code generated by DeepSeek can run directly on a computer without extra steps.

However, it cannot run on mobile devices.
This means that without a computer nearby, you cannot write code and debug it on your phone—quite inconvenient.
To solve this, I used DeepSeek to create a small tool that took just 5 minutes to develop. You can run HTML code directly on your phone. It’s incredibly simple—just open it in your browser.
Of course, you can also deploy this tool on your own server and access it anytime, anywhere!
Development Steps
1. Enter Your Prompt
Write me a complete HTML page.Features:1. An unlimited-length text input where users can enter HTML code (including CSS and JavaScript)2. Two buttons below the input: "Run" and "Clear"When clicking Run, execute the code in the input as HTML in the browser and display the result.When clicking Clear, empty the input.3. Style the entire interface following Linear app's design aesthetic with polished styling for each element.After generation, you can click “Run Online” to see the effect immediately.

If there are issues, ask DeepSeek again to help!
For example, if the Run button doesn’t respond:
The "Run" button doesn't respond. Please regenerate with complete code.DeepSeek will provide the updated complete code, and you continue…
2. That’s It
There’s no step 2—you’re done!
