 # FAQ
+
+## Is the Blocky editor based on other editors?
+
+No, the Blocky editor is written from scratch using the native DOM API.
+
+## Can I use the Blocky editor with Vue/Angular?
+
+In theory, yes. The Blocky editor provides a full VanillaJS API, and you can add your bindings to your favorite frameworks. However, official support for Vue and Angular is not currently in the plans.
