FastMinify vs Qursor

Qursor is a Chrome extension that captures selectors, classes, styles and notes for a chosen page element so coding assistants can make targeted interface fixes.

About FastMinify

FastMinify is a free collection of developer utilities that process input entirely in the browser, so code, configuration files and tokens are never sent to a server. It began as a minifier for JavaScript and CSS and has grown into a hub of more than 215 tools grouped by task: minifying and unminifying, formatting, format conversion such as JSON to YAML, encoding, SVG optimization, and helpers for DevOps, Kubernetes, CI/CD, API schemas and HTTP. There is no account or signup step. Users pick a tool, paste input into the editor, adjust options, and copy or download the output. The interface is offered in English, French, German and Spanish.

About Qursor

Qursor is a Chrome extension built for developers who use AI coding assistants on front end work. Rather than sending screenshots, the user hovers over an element on a production, staging or localhost page, inspects its typography, colours and spacing, and either edits styles directly or leaves an annotation. Qursor then copies the selectors, classes, edits and notes as structured text the agent can act on, which the maker says saves tokens and avoids searching an entire codebase. It can also lift components from live sites as HTML, CSS or JSX, and includes a colour picker with a palette view. A free starting option exists, while paid pricing is not shown on the homepage.
