Were they located at formnano.com? If so, it looks like they don’t exist anymore. That domain just has a generic “domain registrar” page now.
One thing to remember is that ANY form software on the entire web can be linked to Airtable, if you just need to push information into Airtable (as opposed to pulling data from Airtable or updating records in Airtable).
The 2 options I mentioned above (MiniExtensions.com and JotForm + On2Air Forms) will pull data from Airtable into your form, as well as giving you the ability to update existing records in Airtable.
Otherwise, for pushing data to Airtable, you’re free to use any form software on the web.
Some form software, like JotForm, have direct Airtable connections built directly into the product.
For others, you can simply use Integromat or Zapier. (Note that I am a professional Airtable consultant and a Registered Integromat Partner, and the Integromat link contains my personal referral code.)
Also, equally important, even though products like JotForm have direct connections to Airtable, you might STILL want to use Integromat for advanced processing of your form data before putting it into Airtable. Integromat can do whatever you‘d like with your data before it goes into Airtable, and it can put it into Airtable in any way that you’d like.
p.s. If you have a budget for your project, and you need help setting up or integrating forms with Airtable, I am a professional Airtable consultant. Feel free to contact me through my website at scottworld.com.
