configuring, in response to first user input, a first one or more attributes of one or more component behaviors of the selected one or more web application builder components;

retrieving a metadata model associated with the selected one or more web application builder components;

modifying the metadata model by at least adding to or editing one or more nodes of the metadata model, the one or more nodes associated with the first one or more attributes;

storing the modified metadata model in a database; and

causing display on one or more client devices of the web application builder for constructing web applications, the web application builder implementing at least the one or more web application builder components implemented in the one or more development areas.

9. The method of claim 8 , further comprising:

processing a second user request to modify the one or more web application builder components within the one or more development areas; and

updating, in response to the second user request, the one or more web application builder components within the one or more development areas.

10. The method of claim 9 , wherein the second user request to modify the one or more web application builder components comprises at least one of: adding, removing, or modifying one or more attributes of the one or more web application builder components.

11. The method of claim 8 , wherein the first user request comprises a drag-and-drop movement of the selected one or more web application builder components onto at least a portion of the one or more development areas.

12. The method of claim 8 , wherein the selectable list of web application builder components comprises one or more graphical representations of the web application builder components.

13. The method of claim 8 , wherein implementing the selected one or more web application builder components in the one or more development areas comprises presenting a graphical representation of the one or more web application builder components according to an object type.

14. The method of claim 1 , wherein the web application builder and the web application builder framework are browser applications configured to be executable on one or more browsers operating on one or more client devices.

15. A computer program product comprising computer-readable program code capable of being executed by one or more processors when retrieved from a non-transitory computer-readable medium, the program code comprising instructions configurable to cause:

providing, for interaction with a database, an identification of a plurality of web application builder components configured to be used to build a plurality of components of a web application and further configured to be reusable within a server-hosted web application builder framework;

displaying on a client device a user interface for the web application builder framework, the user interface comprising:

a selectable list of a subset of the web application builder components, and

one or more development areas for building a web application builder based on user input;

processing a first user request to select one or more of the subset of web application builder components from the selectable list to be implemented in the one or more development areas;
