Riza offers a solution for safely and easily running untrusted code by providing a Code Interpreter API that can be hosted locally using their Docker image, rizaio/code-interpreter. This setup ensures all data remains within the user's system while initializing Python and JavaScript runtime environments by default. Users must obtain a license key to run the image and can access a free trial by contacting Riza. The API can be interfaced using Riza's SDKs, which require configuring the base URL to the local server. For those not using Docker, Riza provides downloads for Linux and macOS, with plans to expand support to additional operating systems and architectures. The CLI, currently in early release, allows users to initialize default runtimes which may take a few minutes on the first run, and Riza welcomes feature suggestions through their Discord channel.
