About
Prettier Playground is an open-source web app in the developer tools category (code formatter). It opens in your browser, so there is nothing to install. You provide code and options and get formatted code. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (prettier/prettier).
