Provided is a computing device of a group based communication system configured to initiate and execute a group-based communication browser session. An example computing device is configured to receive a group-based communication browser session initiation request. After receiving a group-based communication browser session initiation request, the example computing device will determine whether the computing is connected to an Internet. If the computing device is determined to be connected to the Internet, the example computing device determine whether a group-based communication service cache is available. If the group-based communication service cache is available, the example computing device will fetch a group-based application asset set from the group-based communication service cache. Then the example computing device will determine whether a group-based communication browser cache is available. If the group-based communication browser cache is available, the example computing device will fetch a group-based communication object set from the group-based communication browser cache based on a group-based communication browser cache hydration policy. Then the computing device will render a group-based communication interface using the fetched group-based application asset set and the fetched group-based communication object set.
