5. The computing device of claim 2 , wherein the memory stores additional computer-readable instructions that, when executed by the at least one processor, further cause the computing device to:

receive a user input corresponding to the source data; and

send an indication of the user input corresponding to the source data to the data source computer system, wherein sending the indication of the user input corresponding to the source data causes the data source computer system to generate the updated source data.

6. The computing device of claim 1 , wherein the key value store maintains a reference from each of the one or more dynamic elements to the DOM structure.

7. The computing device of claim 1 , wherein the memory stores additional computer-readable instructions that, when executed by the at least one processor, further cause the computing device to receive user input requesting access to the first graphical user interface.

8. The computing device of claim 1 , wherein the memory stores additional computer-readable instructions that, when executed by the at least one processor, further cause the computing device to:

identify, based on one or more bind attributes associated with tags in the HTML page, the one or more dynamic elements.

9. The computing device of claim 1 , wherein the memory stores additional computer-readable instructions that, when executed by the at least one processor, further cause the computing device to store, locally on the computing device, the key value store.

10. A method comprising:

at a computing device comprising at least one processor, a communication interface, and memory:

receiving, from a web server host platform, a HyperText Markup Language (HTML) page comprising a document object model (DOM) structure, wherein the DOM structure includes one or more dynamic elements;

parsing the DOM structure associated with the HTML page received from the web server host platform to generate a logical DOM, wherein the logical DOM comprises a key value store identifying a subset of one or more dynamic elements to be updated based on data received from at least one data source different from the web server host platform, wherein the key value store does not include remaining dynamic elements, and wherein the remaining dynamic elements are not to be updated;

receiving, from a data source computer system, source data;

modifying the logical DOM based on the source data, wherein modifying the logical DOM based on the source data comprises replacing the subset of the one or more dynamic elements with corresponding values from the source data received from the data source computer system, and wherein modifying the logical DOM produces a first updated real DOM;

rendering, after completing the modification of the logical DOM and without displaying the logical DOM, a first graphical user interface based on the first updated real DOM; and

displaying the first graphical user interface.

11. The method of claim 10 , further comprising:

receiving, after displaying the first graphical user interface, updated source data from the data source computer system;

modifying the modified logical DOM based on the updated source data, wherein modifying the modified logical DOM based on the updated source data comprises replacing the one or more dynamic elements with corresponding values from the updated source data received from the data source computer system, and wherein modifying the modified logical DOM produces a second updated real DOM;

re-rendering the graphical user interface based on the second updated real DOM; and

display the re-rendered graphical user interface.

12. The method of claim 11 , wherein receiving the source data comprises receiving user account data.

13. The method of claim 12 , further comprising:

retrieving, after receiving the updated source data, the first updated real DOM; and

determining, based on the first updated real DOM, the modified logical DOM.

14. The method of claim 11 , further comprising:

receiving a user input corresponding to the source data; and

sending an indication of the user input corresponding to the source data to the data source computer system, wherein sending the indication of the user input corresponding to the source data causes the data source computer system to generate the updated source data.

15. The method of claim 10 , wherein the key value store maintains a reference from each of the one or more dynamic elements to the DOM structure.

16. The method of claim 10 , further comprising receiving user input requesting access to the first graphical user interface.

17. The method of claim 10 , further comprising:

identifying, based on one or more bind attributes associated with tags in the HTML page, the one or more dynamic elements.

18. The method of claim 10 , further comprising:

storing, locally on the computing device, the key value store.

19. One or more non-transitory computer-readable media storing instructions that, when executed by a computing device comprising at least one processor, a communication interface, and memory, cause the computing device to:

receive, from a web server host platform, a HyperText Markup Language (HTML) page comprising a document object model (DOM) structure, wherein the DOM structure includes one or more dynamic elements;
