Devsy by Moksedul Islam

Devsy is a smart web development toolkit that helps you understand, debug, and improve any website — right inside your browser.

Inspect fonts, colors, layouts, and spacing with a single click. Measure elements, explore Grid and Flex layouts, and quickly spot CSS issues without digging through code.

Take full-page screenshots, annotate them, and leave notes directly on a website for easy reviews or collaboration.

Devsy also helps with SEO and performance by checking meta tags, previewing search results, validating schema data, and detecting the technologies used on a site.

Everything runs locally in your browser. No tracking, no data collection, and no internet required.

Built for developers, designers, and testers who want faster answers and a smoother workflow.
