Show HN: WordBulb – Interactive Word Cloud Generator You Can Use for Navigation

[rkj93]

Hey HN,

I’ve been building a few SaaS products over the last couple of years, and in between larger features I sometimes build small tools to reset my brain. This started as one of those.

It’s called WordBulb:

At first, it was just a simple word cloud generator. But while building it, I kept thinking: why are most word clouds basically just decorative images?

They look interesting, but they’re not useful.

So I decided to make it interactive and embeddable — where every word can have its own target link.

What it does

Add your own words

Assign a custom URL to each word [the clicked word can be passed as query parameter]

Generate an interactive SVG word cloud

Embed it directly into your site

Each word is clickable.

You can use it as:

A visual table of contents

A tag cloud alternative

A creative way to surface affiliate links

A keyword visualization block inside a blog post

Instead of a boring list of links, you get something more dynamic and visually scannable.

Why I built it

I work a lot with SEO-heavy products and content-driven sites. I’ve always liked the idea of visual navigation — not just menus and bullet lists.

Tag clouds used to be popular, but most implementations are static and uninspiring.

I wanted:

Full control over words

Manual link mapping

Clean SVG output

Something lightweight that doesn’t depend on external libraries

It also fits into a broader idea I’ve been exploring around visual startup directories and keyword-based navigation systems.
