Tools Hub
Free online text, developer and SEO tools in browser
About Tools Hub
Tools Hub is a free collection of browser-based utilities for writers, developers and SEO work. Its catalog covers word and character counters, case converters, password generators, JSON formatting, QR code creation, hash generation and regular expression testing, among many others.
The site is aimed at anyone who needs a quick text or developer utility without signing up. Tools open instantly, and the site states that data is processed locally in the browser rather than sent to a server, which is its main selling point alongside the lack of registration or subscriptions.
The homepage advertises a searchable directory of more than fifty tools, organized into groups such as text and writing, converters and encoding, generators, SEO, developer tools and security. Mobile and desktop use are both supported, and the site makes no claims about AI features or integrations with AI assistants.
