Vibe Coding

Recently, I learned about Vibe Coding. It is a relatively new concept in software development, popularised by Andrej Karpathy in early 2025.

He describes an approach where developers heavily rely on AI, particularly large language models (LLMs), to generate functional code from natural language prompts.

There's a new kind of coding I call "vibe coding", where you fully give in to the vibes, embrace exponentials, and forget that the code even exists. It's possible because the LLMs (e.g. Cursor Composer w Sonnet) are getting too good. Also I just talk to Composer with SuperWhisper…

Cool concept!. I embraced it with a recent feature development in SUIS.co landing page.

I'm always on the lookout to optimise the SUIS.co's landing page to improve conversion. Based on my analysis of Session Replay in PostHog. I found that visitors from Malaysia are browsing the Worldwide landing page without switching to the Malaysia region.

SUIS.co supports multiple regions, and the landing page shows content specific to the regions. For instance, our Malaysia landing page shows plan & pricing in RM, and the Worldwide landing page shows pricing in USD. The page has a region dropdown to allow visitors to switch correct region, but not all visitors switch to the correct region.

So, to fix this, I want to show a pop-up to alert visitors to visit the correct regional site whenever they visit the landing page of a different region.

We can match the visitor's browser IP address location with the landing page's URL region parameter to find a mismatch and show the pop-up. I wanted to try Vibe Coding to build this feature.

My steps:

1. Identify websites with similar features and understand the design & workflow.
2. Write a prompt to create the feature.
3. Refine with additional prompts.
4. Copy and paste the code into SUIS.co landing page.
5. Deploy. 🚀

Initial result:

This is the final result:

This is the prompt I used to build the feature:

Pretty cool🙌

There are many tools out there specifically for Vibe Coding, such as GitHub Copilot, Amazon Q Developer, and Cursor.

My take on Vibe Coding: it's very useful for building simple features such as above, but when it comes to complex features, it still needs a human touch.
