What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. acquisition value

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A declining trend compresses what a buyer would pay.

    Unfortunately, the plugin doesn’t support Java, Kotlin, Flutter nor XML syntax, making it completely useless for anyone in the Android development field.

    I don’t normally use WP Blocks and so I could not figure out why this plugin broke for certain code syntax (PHP -> HTML -> PHP for example) and why saving sometimes broke the previously-saved syntax. Maddening. Then I switched back to the block editor. AHA! It works beautifully. That’s probably why it says “Block” in the plugin name, duh. Thank you very much for this wonderful plugin. I love that we can also upload our own prism.js files. Cool.

    The plugin developer and the plugin itself are very good. Wish them all the best. Being a developer takes a huge time, effort, money & sacrifice. If you’re a user of this plugin like me, do not just leave your negative feedback unless you talked to the support. Also, if you were a backbencher like me and if you’re still a backdated who uses an older version of PHP (just like me), please feel free to use this plugin with peace of mind. Enjoy!

    Thanks for the amazing work. Please work on the Performance like Asset Size and try to merge them into a single JS and CSS.
