01It can be built without a mouse
The drag-and-drop canvas has a full keyboard equivalent: every field can be added, moved and removed from the keyboard alone. A builder that only answers to dragging shuts out the people who cannot drag.
02Thirty-eight field types
Text, email, telephone, URL, number, date, time, dropdown, radio, checkbox, rating, slider, colour, file upload, name, address, ordering and page break cover the ordinary form; signature, repeating groups, a matrix, a quiz, a calculation and an order total cover the one you thought would need a second plugin. All thirty-eight are in the free package.
03Columns that keep the reading order
A field placed in a column is still read in field order, so a screen reader and a sighted visitor meet the same form in the same sequence.
04Conditions are decided on the server
Nested AND/OR groups with fourteen operators, evaluated again when the form is submitted. A field hidden in the browser cannot be slipped past by editing the page, and the rules still hold with JavaScript switched off.
05Access rules the browser cannot argue with
Open and close by calendar, cap the number of entries, require a login or a role, or set a password. A closed form refuses a direct submission on the server — not by hiding its button.
06Spam is marked, not deleted
A honeypot and a time trap are on by default and get in nobody’s way; reCAPTCHA v2/v3, hCaptcha, Turnstile, Akismet and keyword, IP and email block lists are optional. What is judged spam is flagged and kept, because a false positive should not cost you a customer.
07Uploaded files are not in the web root
They are written outside it, into a directory nobody can guess, and checked by what the file contains rather than what it is called. They are handed out only through a time-limited link tied to one person.
08Notifications you can audit
Several per form, recipients routed by a field value, an auto-reply to the sender, and a delivery record of what was sent, what failed and why — with a resend for the ones that failed.
09Take a PayPal payment
Pro adds a PayPal gateway on Orders v2: the order is opened on your server, approved on PayPal’s own page and captured on the way back — or from the signed notification if the visitor closes the tab. PayPal is not available in Türkiye, so this is for selling abroad; Turkish providers stay on the MevvPos bridge.
010Zapier and Make, without the glue
Pro publishes entries as REST hooks: Zapier subscribes to a form, later entries are queued to it, and a samples route gives the mapping screen real field names. A signed webhook was always in the free edition — Pro removes the wiring in between.
011Entries that land in Salesforce
Pro turns a submission into a Lead, a Contact or a Case. It signs in with a refresh token rather than a password, and a sandbox is a setting rather than a second set of credentials to keep straight.
012Uploads on your own object storage
Pro can move the file vault onto any S3-compatible store — AWS S3, Cloudflare R2, MinIO, DigitalOcean Spaces, Backblaze B2, Wasabi — signing every request itself. The free edition keeps the same vault on your own disk; what Pro changes is where the bytes sit, not who is allowed to fetch them.
