SDK Overview

DevCycle has both client-side and server-side SDKs. This page serves to describe the differences between these SDK types and how to handle them. Implementation and usage change depending on which type of SDK is being used.


Explore our SDK Features and Functionality to discover how to impliment your solutions using the DevCycle SDKs.

DevCycle client-side SDKs are meant for single-user contexts. This means that the SDKs have a persistent data store for the user while the SDK is being used. Evaluation of Features happens directly on the client's device. These SDKs also include the Mobile SDKs. For more information on the difference between mobile and standard client-side SDK keys, read API and SDK keys.

The current Client-Side SDKs are:

Difference between Local and Cloud Bucketing

Local bucketing does all of the calculations locally using extremely performant Web Assembly code. The project's environment configuration is downloaded upon initialization of the SDK, and all future SDK calls will calculate values locally within the SDK. This approach will guarantee responses from the SDK in 1-10ms. The configuration will be updated at a configurable polling interval.

SDK Proxy

Designed for cases where the language design doesn't support a long lived background process to contain the Local Bucketing engine and configuration data; the Local Bucketing Proxy was made to emulate the Cloud Bucketing API's and allow and SDK to have greater performance; close to that of the local bucketing SDKs. For more information see SDK Proxy.
