About Dart Syntax
Working with developer and design work no longer requires installing heavy desktop software — Dart Syntax runs entirely in your browser, instantly. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. It is one of about a hundred developer tools that share the same philosophy: do one thing, do it well, get out of your way.
