SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
If you're interested in mapping infrastructure, you may like Overpass Turbo.
It maps all kinds of stuff, selectable via queries, such as water fountains, parking lots, etc. I've always thought it could come in handy during times of emergency, such as if FEMA needed to inform citizens of certain resources in their vicinities.

Example 1] - Defaults to amenity=bottled_water -- Search & select "San Francisco" and click "Run" (Click "Load" for other demo options.)
[Example 2] - Parking lots in SF https://help.openstreetmap.org/questions/67865/overpass-turb...
Example 3] - Go back to the default example of bottled water: click "Load" --> select the "bottled_water" example. Now change [amenity=drinking_water] to ["shop"="butcher"]
[Example 4] - Multiple nodes, as categories of suppliers -- Paste this into the Overpass console: https://pastebin.com/Q4X2YPvj to see nodes where shop=butcher, farm, agrarian, greengrocer
