Local Webmaster Toolbox

A free, no-login webmaster toolkit with common utilities in one place

Problem

Webmasters and developers often need scattered web tools like encoding/decoding, URL parsing, IP lookup, or regex testing. Existing sites force logins, are ad-ridden, or upload data to servers, hurting privacy and efficiency.

Solution

A suite of pure front-end, locally running webmaster tools where all computation happens in the browser with no data upload and no login. Covers common tasks like UTM building, encoding conversion, HTTP header analysis, and DNS lookup, with a clean UI and dark mode.

Users

Independent webmasters, SEO practitioners, front-end developers, and ops engineers

MVP

Implement 10 most frequent tools (encode/decode, URL parsing, JSON formatting, UA parsing, IP/CIDR calculation, etc.); all local JS; no login; responsive UI; dark mode

Revenue

Free to use, sustained by donations or sponsorships; optional paid desktop version (offline, batch processing)

Why now

Rising privacy awareness makes users averse to uploading sensitive data to third-party sites; pure front-end is technically simple for indie developers to launch and spread via community
