AMP Validation

AMP pages are automatically validated with amphtml-validator during development. Errors and warnings will appear in the terminal where you started Next.js.

Pages are also validated during Static HTML export and any warnings / errors will be printed to the terminal. Any AMP errors will cause the export to exit with status code 1 because the export is not valid AMP.

Custom Validators

You can set up custom AMP validator in next.config.js as shown below:

module.exports = {
  amp: {
    validator: './custom_validator.js',

Skip AMP Validation

To turn off AMP validation add the following code to next.config.js

experimental: {
  amp: {
    skipValidation: true
