Ever since Airtable changed their Attachment URL expiry window to 2 hours, I had to setup automations using Make to upload files to S3.

This worked great, but I recently build a custom extension to get this to work without using Make.

So, I started building an Airtable extension to bridge this gap. The goal is to keep it all inside the Airtable UI (see the screenshot of what I have so far):

  • You select your attachment field.

  • The extension mirrors the file to a permanent bucket in the background.

  • It writes the non-expiring CDN URL back to a field of your choice.

I’m still polishing this, but I wanted to see if anyone else would actually find this useful compared to the current Zapier/Make methods.

Is "reduced friction" enough of a reason to switch, or are most of you happy with your current S3 setups? If there's enough interest, I'll keep pushing to get this ready for a public release.
