It is smart to be cautious about investing in dead code.
Something to note is that the Airpress plug-in does not have a paid “premium” version that generates income for the developer. Thus, he does not have an incentive to update or test the plug-in, or to answer support questions.
On the other hand, the developer has replied to some support questions within the past few weeks and he has updated the plugin five months ago. His website also lets you book Airpress support consultations.
I’ve also used rollups and formula fields to create HTML from Airtable data. I then push the html to my WordPress site using a custom block that I created specifically for the purpose. The data doesn’t auto-update the way Airpress or another integration would, but my data changes infrequently enough that a manual update method works for me. From a search ranking point of view, the data is just like any other WordPress post.
