What it does
KwesForms receives submissions from HTML forms built for your own website. You connect each form to an account endpoint and can add browser validation through an optional script. Free Forever supports one form and 100 monthly submissions; paid plans increase form, response, storage and user allowances.
In your KwesForms account, add a website and name its form. Copy the supplied endpoint into your HTML form's action, use POST and give each input a unique name. The first submission connects it to the backend.
For browser validation and special fields, load the optional script and add the kf-form class. WordPress editors may remove custom attributes; the alternative data-kw-* attributes help with that integration.
