About Curio Attic

A small home for independent, local-first web apps — things made from curiosity.

Curio Attic hosts a handful 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.

Idea Harbor

ideaharbor.curioattic.com 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.

Tool Trove

tooltrove.curioattic.com 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.

Web Parking

webparking.curioattic.com lets you close tabs without losing your place. A browser extension lets you right-click any page or tab group and park it into a named group instead of leaving it open "just in case." The dashboard at webparking.curioattic.com is where you organize those groups and resume them later — reopening only the tabs that aren't already open. No account, no backend: everything is stored locally in your browser and can be exported or imported as a plain JSON file.

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.
