When it comes to 2-way data syncing between apps, that's where tools like Zapier and Make fall apart.
If you're looking for the most powerful 2-way sync on the market between the apps that Whalesync works best with (e.g. Webflow, Airtable, Notion, and HubSpot, amongst others), then there's no other place to look.
Our Webflow site has actually gotten so complex, that we relied quite heavily on Whalesync to manage all of these apps and listings within Airtable using Whalesync. Efficient App and Efficient Stacks are actually totally separate Webflow sites, so we use Whalesync to connect them through Airtable. It's pretty powerful.
Important note: We do not use Whalesync + Airtable for managing/writing blog posts or any in-depth rich text fields, as Airtable does not allow for inline images or code snippets (and Webflow doesn't allow for "open in new tab" links within rich text fields via their API), so if you have those fields enabled, they will overwrite all of your rich text in-line images/code blocks and you will have to do a backup recovery within Webflow (please learn from our mistakes).
