Is this only for building internal tools? Or is it possible to build apps which collect data from end users with support for auth and access control?

It seems that there are a lot of such platforms for internal apps. E.g. Retool, Airtable. Are there any no-code tools that support building external-facing apps? Apps that can collect data from untrusted external users?

Something that combines the features of Wufoo and Airtable in a single cohesive and flexible service?

Airtable itself lets you expose simple forms to the public internet.

Then there are dedicated form tools like Fillout that let you build more complex forms that integrate with Airtable.

Teable can currently share forms to get data from external users. You can also integrate with other lowcode tools to build external application interfaces
