The new Elixir SDK from Harness allows development teams to integrate feature flagging and event tracking directly into their Elixir applications without altering their existing tech stack. Built as a lightweight and efficient solution, the SDK leverages Split Daemon to connect to Harness Feature Management & Experimentation (FME) seamlessly. Initially developed in collaboration with Cars.com, the Elixir SDK has been enhanced for broader compliance with Harness and is now available for all customers. This thin client SDK is particularly beneficial for Elixir, a language widely used for scalable and fault-tolerant applications, as it improves performance with low latency, enhances security by keeping data within the local network, and simplifies maintenance by standardizing feature flag implementation. It supports native feature flagging, simplifies multi-language support, and is optimized for high-traffic applications, enabling companies to deploy and experiment confidently. The release of the Elixir SDK demonstrates Harness's commitment to providing scalable, secure, and accessible feature management solutions across diverse tech stacks.
