About 866570.xyz

A small home for independent, local-first web apps.

866570.xyz hosts a couple of free tools built to be fast, private, and useful without asking anything of you — no accounts, no tracking dashboards, no uploads to a server you can't see. Each app runs entirely in your browser.

Chintapot

chintapot.866570.xyz is a free, local-first visual whiteboard. It turns scattered thoughts into clear concepts using sticky notes, shapes, connectors, and diagrams. There's no account and no signup — your board lives in your browser.

Doohickory

doohickory.866570.xyz is a free toolbox of browser-based utilities for developers and everyone else: JSON formatting and validation, Base64/URL/HTML encoding, text utilities, image conversion, and more. Nothing is uploaded — every tool runs client-side.

Why local-first

• Your data stays on your device unless you explicitly export or share it.
• Apps load fast and keep working even on a flaky connection.
• No account walls between you and the tool you came for.
