Free tools, built in the open

Small products we've built and use ourselves — free for anyone, with no signup wall.

Otical TextUtils

A fast, no-signup text utility: word and character counts, reading time, case conversion and one-click whitespace cleanup.

Inspect local files and run CPU/GPU workloads entirely on-device using the Web Crypto API and multi-threaded workers - zero bytes sent to cloud.

An online file sharing portal built with Firebase — anyone can register, but only users verified by an admin can access, upload and download files.

A simple, client-side password generator with adjustable length and character sets — nothing is sent to a server.

Flip two cards per turn and match identical pairs in the fewest attempts — dynamic shuffling, turn tracking and smooth 3D flip animations.
