About
ESLint Playground is an open-source web app in the developer tools category (linter). It opens in your browser, so there is nothing to install. You provide code and rule config and get lint messages. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (eslint/eslint).
