I Got Tired of Slow, Ad-Heavy Developer Tool Websites — So I Built My Own

As developers, we use small utility tools constantly.

Sometimes dozens of times per day.

formatting JSON
testing regex
decoding JWTs
comparing text
generating UUIDs
building cron expressions
debugging API payloads

These tiny tasks are part of everyday development workflows.

But over time, I started noticing something frustrating:

Many online developer tool websites still feel stuck in another era.

Pages overloaded with ads.
Cluttered interfaces.
Popups everywhere.
Slow loading.
Confusing mobile layouts.

And in some cases, it’s not even clear whether your data stays in the browser or gets sent somewhere else.

After enough frustration, I decided to build my own toolbox.

Building Devstoolsbox

I created Devstoolsbox as a collection of browser-based developer tools focused on:

speed
simplicity
modern UX
privacy
mobile usability

The idea was simple:

What if developer tools felt lightweight again?

Instead of creating another giant utility directory with hundreds of pages, I focused on tools developers actually use regularly.

Current tools include:

JSON Formatter
Regex Tester
JWT Decoder
Text Diff
UUID Generator
Cron Generator
AI Token Counter
CSS Shape Generator

One thing I cared about from the beginning was reducing visual overload.

A lot of older utility websites evolved over many years without a full redesign, so interfaces became dense and inconsistent over time.

I wanted something cleaner and calmer.

Why Browser-Side Processing Matters

This became especially important while building tools like:

JWT decoders
JSON formatters
AI token counters

Developers often paste sensitive information into online utilities without thinking about it:

API responses
internal logs
JWT payloads
config files
prompts

That’s why many Devstoolsbox tools run entirely in the browser.

No account required.
No unnecessary uploads.
No hidden complexity.

Modern browsers are powerful enough now that many utilities simply don’t need server-side processing anymore.

The Unexpected Challenge: SEO for Developer Tools

One thing I underestimated was how competitive developer tool SEO is.

There are already huge established platforms with years of authority and backlinks.

At first I thought:
“If the tools are useful, people will naturally find them.”

Reality is more complicated.

Developer tool websites compete against:

old domain authority
massive tool collections
years of indexed content
thousands of backlinks

So I started experimenting with something different:

Instead of writing generic AI-generated “ultimate guides,” I began creating articles that combine:

practical examples
real developer observations
UX discussions
tool comparisons
common mistakes
browser-side workflow explanations

That approach feels much more sustainable long-term.

AI Is Changing Developer Workflows Fast

The biggest surprise recently has been how quickly AI-related utilities became important.

A year ago, nobody cared about token counters.

Now developers constantly need to understand:

token costs
context windows
prompt optimization
GPT vs Claude vs Gemini limits

That’s why I recently added an AI Token Counter that estimates prompt usage and compares token counts across models.

It’s interesting watching how fast developer tooling evolves around AI workflows.

What I Learned Building Developer Tools

A few things surprised me during the process.

1. Developers care about UX more than expected

Even technical users appreciate cleaner spacing, typography and faster interfaces.

1. Mobile developer workflows are growing

A lot more developers test snippets and debug directly from phones than I originally expected.

1. Simplicity is harder than adding features

It’s easy to keep adding buttons and options.

Keeping tools focused is much harder.

1. Privacy is becoming a real selling point

More developers are starting to ask:
“Does this tool process data locally?”

That question barely existed a few years ago.

The Goal Going Forward

I’m still expanding Devstoolsbox gradually.

Right now, the focus is less about building hundreds of tools and more about improving:

usability
speed
documentation
AI workflows
internal tooling
educational content

I’d rather build a smaller collection of genuinely useful tools than a giant directory filled with duplicate utilities.

And if you’ve built developer tools yourself, I’d genuinely love to hear what challenges surprised you the most.
