Toolbox Atelier – local browser toolkit

40+ small tools in one local-first web app, nothing leaves your browser

Problem

Developers, designers, and ops people juggle dozens of small utilities for conversions, encoding, image work, and text cleanup. Most online tools demand an upload, which is a privacy concern, while building your own toolbox from scratch is repetitive.

Solution

An opinionated local-first toolbox: dozens of high-frequency utilities that run entirely in the browser, with drag-to-use, batch mode, and offline PWA support. Each tool is a reusable component, and users can contribute template-based patches for new tools.

Users

Privacy-conscious developers, designers, ops staff, and everyday users who handle files often

MVP

Ship 10-15 high-frequency tools (encode/decode, image compression, format conversion, text cleaning, QR); fully client-side and instant; PWA offline; tool search and recents; one-click copy/export

Revenue

Free basics plus paid batch processing and history sync at a $19-29 one-time price; private enterprise deployment available

Why now

Local-first and privacy anxiety are rising while WASM makes serious in-browser processing practical; utility sites prove demand but lack a unified privacy-first option.
