A toggle is a switch or button that allows users to switch between different settings or modes. It’s commonly used in everyday technology devices like keyboards to enable/disable functions such as Caps Lock and Num Lock. It’s also a popular feature in software applications where it can be used to roll out features to users in stages.

Feature Toggles are a way for engineering teams to test new features in a live production environment without risking the user experience. They can be turned on for select users in a Canary Release and then remotely rolled back if the experiment fails to meet expectations or encounters bugs. Using Feature Toggles can significantly speed up the testing cycle and reduce time to market for new product features.

Toggles are also an effective tool for maintaining and stabilizing application performance during high-latency periods. They help teams control the number of servers that are active in the production environment and prevent a single server from becoming overwhelmed by requests and impacting the overall experience for users.

When it comes to application performance, a key component is the ability to quickly respond to user demands and shift resources as needed. Using a combination of Toggles and automation helps teams make changes to the application with minimal impact to performance and stability.

The concept of Toggles is simple on the surface but there can be some complexity in how a company implements and manages them. Some teams choose to hardcode their toggle configuration into static files which is fine until you reach a certain scale when modifying the configuration becomes cumbersome and can be difficult to maintain across a fleet of servers.

Other teams opt to use a version control system which allows them to dynamically change the configuration of their toggles through code deployment. While this approach is more flexible than the previous one, it requires an agreed upon pattern for deploying code to servers in order to re-configure a toggle.

Kameleon’s Feature Toggles feature is built with these considerations in mind. With Kameleon you can create your Toggles in a central repository and use our admin UI to manage and modify them. In addition to this, Kameleon will automatically create a deployable version of your Toggle and execute it against each deployment, making it easy to roll out new features to users in the real world.

Lastly, Kameleon back-tests every Insight against a historical data set to ensure that it can accurately predict the direction (and sometimes magnitude) of an asset’s price movement. This is particularly important in times of volatility when a Toggle can be especially valuable in helping investors navigate with confidence. The results of this rigorous back-test are displayed on the Insights page and help to support seasoned investors during times when they might otherwise struggle to predict market direction.
