Been a user for a couple of years, since it first went into beta - loved it then and still do. So many possible uses, beyond simple forms.
This is one of the most productive tools I have used in a long time. Making forms is easy; editing is easy and distributing the form is even easier.
Been using Paperform for over a year with good results. Respondents liked the design and clarity in form formats. Responsive anywhere it appeared.
It has been an evolving product. I remembered 15 months or so ago it just introduced conditional logic, now it has almost every control features.
I still wish it has direct integration with Google Sheet and other popular services, though. Zapier and webhooks are both good and I'm using them, but it is costly and/or I have to touch the code.
Can't love this product any more. Ok, I can, if it directly let you work with its API, it would save you a ton of cost in Zapier. The deal is this. You likely want to use Paperform to collect a ton of data (polls, emails, etc.) and then forward that to somewhere else. What makes that problematic is then you integrate Zapier and the costs per "Task" per month over there really starts adding up. Soon you realize your beautiful automation solution is quite expensive (not to mention convoluted). So being able to code against Paperform yourself would save you from paying Zapier, but how much that hurts your wallet depends on your use case.
The other thing is the styling is great, but limited in important areas. The "Active" color is tied to form field text as well as the submit button. This can be problematic for brighter colors. It doesn't stand out well against the white form input background. Then custom success pages link colors can't be adjusted either (same active color) so you're a bit stuck.
IF they were to provide API access and more (not even a lot more, just a little) CSS customization...This service would be perfect.
