Today we added a new captcha option to protect your forms and also a new validation option for upload fields.

ALTCHA captcha

We've introduced a new captcha option: ALTCHA. This self-hosted solution ensures that no data is transmitted to third-party vendors, offering a privacy-friendly alternative to our existing Google reCAPTCHA option.

We also plan to add support for Turnstile (via bring your own key) within the next couple of weeks.

MIME validation

We also added a new validation option for the upload field. You can now define which formats are allowed for people to upload.

This rule validates the MIME type of the file by reading the file's contents and guessing its MIME type. When creating this rule, you only need to supply the extension, e.g. jpg,webp,png and the rest is done behind the scenes.
