AppCrib

The free tools you should'vehad years ago.

Formatters, validators, converters, calculators. The ones that exist are cluttered, dated, and painful to look at. These aren't.

Instant

Open it, use it. Everything runs in your browser — there's nothing to load or wait for.

Private

Your data stays on your device. We don't upload it, process it on a server, or peek at it.

Well-designed

Somebody actually thought about the UI. These aren't the janky tools you're used to settling for.

Free. Actually free.

No "sign up to continue." No premium tier lurking behind the good features. Just use them.

The Toolkit

Every tool is free, runs in your browser, and works without an account. Pick one and go.

Who builds these?

Infinite Orchard makes the small, focused tools that should already exist but somehow don't. One tool, one job, done right.

We give them away because most everyday tools online are genuinely terrible, and we'd rather fix that than charge people for the privilege.
