Building the first toolbox slice
Notes on starting with fast local tools before thinking about monetization or paid features.
When I started yueyekidl.com, the temptation was to build everything at once: accounts, payments, analytics, a polished marketing page. None of that helps a visitor in the first ten seconds.
So the first slice is deliberately small. Two tools that run entirely in the browser — a text counter and a JSON formatter. No login, no server round-trip, no waiting.
Why local-first
The strongest argument for processing data in the browser is not performance. It is trust.
People will not paste sensitive JSON or a draft of their writing into a random tool that ships it to a server they cannot inspect.
Local-first removes that doubt. The data never leaves the device, which means the tool can be honest about privacy without a long privacy policy.
What comes next
The plan is simple and slow on purpose:
- Add tools that solve a repeated pain.
- Write a short note explaining each one.
- Only add server features when local processing is genuinely not enough.
Payments come last, not first. A useful free tool earns more trust than a locked paywall ever will.
// The whole tool is just a pure function + a textarea.
function countText(input: string) {
return { characters: input.length };
}
That is the entire philosophy: small, testable, useful.
