Templates-friendly

Curlylint is meant to work directly with source templates, so it can be used like any other static analysis tool – in your IDE, Continuous Integration, or pre-commit hooks.

Catch errors before your users do

The sooner errors are caught, the easier to fix. Create valid, accessible HTML by default.

Accessible by default

Curlylint’s main purpose is to catch accessibility issues – automate the basic checks, so you can focus on tests that cannot be automated.
