If you want to grandfather into ACF Pro‘s current one-time licensing fee, time is running out.
Starting on Monday, February 24th, 2020, Advanced Custom Fields Pro is changing its pricing model to be subscription vs. one-time licensing fee. The new pricing has three tier levels: $49/yr for 1 website, $149/yr for 10 websites and $249/yr for unlimited websites.
We're big fans of ACF Pro and completely understand the need to evolve to a new pricing structure that is more reflective of the value they're providing. ACF has evolved adding new field types and features. Recently, they adding a path to creating custom Gutenberg blocks, which we'd encourage everyone to check out if you haven't yet. You can read more about the reasoning behind making the change on their blog post.
If you want to get in on their current pricing, which is a steal, you can do so for a few more days. Again, this new pricing goes into effect on Monday, February 24th, 2020.
