New product: Tag Checker

Just vibe coded a tool for checking semantic HTML tags in a website because the top results all kinda sucked or just didn’t show the tags in a way I wanted:

So what this tool does is it parses and checks your website or any URL for stuff like H1, H2, H3 and p tags, and shows it back to you in a stacked way, from top to bottom of your site. It just helps you check your work, after adding semantic HTML (I had to do this for my freelance gig).

I used Perplexity’s Sonar Pro actually, and it did this in like 10 minutes… I didn’t even need to bring in the big guns like Cursor/Claude! The amazing thing is… it overcame CORS issues by bringing in a open source CORS tool I never knew, and it worked really well. Benefits of a search-based LLM?

Today I learned. (And who says you learn nothing from vibe coding?!)

It’s wild how easy and throw-away this feels, to go from thought to idea to functioning app in under one hour.

The era of disposable personal software is here.
