Ad-free Online Tools

20+ browser-local utilities, no popups, no uploads, no tracking

Problem

Online tool sites are flooded with ads: formatting JSON requires closing three popups, compressing images means uploading to someone else's server, hurting both privacy and experience. Users crave a clean, fast, local toolset.

Solution

A pure browser-based tool collection including JSON formatter, QR code generator, image compressor, Base64, JWT parser, regex tester, and 20+ more. All processing is local, data never leaves the browser, interface is clean and ad-free, with multi-language support.

Users

Developers, designers, privacy-conscious general users

MVP

20 common tools; fully local execution; no ads or tracking; responsive UI; multi-language support (at least EN/ZH/JA)

Revenue

Completely free, funded via GitHub Sponsors or one-time donations; optionally paid API for automation needs

Why now

Users' tolerance for ads and privacy invasions is decreasing, while existing tool sites are ad-ridden. Indie developers can quickly build alternatives with modern frontend tech and zero server cost.
