How do you approach building small browser tools that people actually use?

Hi everyone,

I’ve been experimenting with building small utilities that run entirely in the browser, mainly to keep things fast and avoid unnecessary friction like logins or file uploads.

One thing I’ve noticed is that for simple tasks, people seem to value:

  • instant load time

  • no setup or signup

  • clear, single-purpose interface

It made me rethink the usual approach of adding more features versus keeping tools extremely focused.

For those of you who have built similar utilities or internal tools:

  • What made them genuinely useful to others?

  • Did you prioritize flexibility or simplicity?

  • Any mistakes you’d avoid if starting again?

Curious to hear real experiences and lessons learned.

That is very vague.

I try to prioritize both.

That’s fair, I should have been more specific.

A concrete example is tools like JSON formatter, text converters, or small PDF utilities where the user just wants to open, do one quick task, and leave. In those cases, I’ve found simplicity matters more — fast load, clear input/output, and no extra steps.

Earlier, I tried adding more options and settings, but most people ignored them. The tools that got reused were the ones that stayed focused and predictable.

So over time I’ve been leaning more toward simplicity first, and only adding flexibility when there’s a clear need.
