What are the limitations of DEV3 Formstead I should know before buying?

Good to know before you buy

• You are the merchant of record. Respondents pay through your payment gateway. Workspaces do not connect their own Stripe account: they receive a takings balance and payout batches, and tax, invoices and refunds are your responsibility.
• Drivers are simulated until you configure them. The payment gateway, the captcha, the file scanner and mail are simulated out of the box. The scanner recognises the standard test string only; to scan real uploads you connect your own scanner. The built-in captcha is a stand-in: a real challenge needs your own verifier and keys. Mail goes to the log until you set SMTP. Stripe, Razorpay and PayPal drivers are present and need your keys.
• Sign-in required forms use an emailed one-use link and a first-party cookie, so they do not work inside another site's embed.
• A partial refund keeps the response complete; the payment row shows the refund.
• Web only. There are no mobile apps.
• Name: Formstead is a working name checked by a web search only, not a trademark clearance. Check it before launching under it.
• No hosted demo. The brands, people and places in the screenshots are fictional.
