Riza offers a secure, low‑latency code execution service that runs LLM‑generated Python, JavaScript/TypeScript, Ruby, and PHP code in isolated WebAssembly sandboxes. Developers can invoke execution via a REST API or SDKs with configurable environment variables, network access, and filesystem permissions, ensuring safe, fast execution without risking production systems.

Problem
LLMs can generate code but executing that code safely and quickly is difficult, especially when the code may be untrusted or require specific runtime environments. Without isolated execution, developers risk exposing production systems, secrets, and resources to malicious or buggy code.
Solution
Riza provides a secure, low‑latency code execution service that lets AI applications run generated Python, JavaScript/TypeScript, Ruby, and PHP code in isolated WebAssembly sandboxes. Each request runs in a stateless Docker container with configurable environment variables, network access, and filesystem permissions, ensuring that code cannot affect the host system or access unauthorized data. The platform offers an API‑first design with client libraries for Python, Node.js, and Go, enabling developers to invoke code execution via simple REST calls or SDK methods. Riza’s service starts executing code in under 10 ms, eliminates cold‑start overhead, and supports custom runtimes for additional packages. For organizations with strict compliance needs, Riza can be self‑hosted as a single Docker image, providing the same isolation guarantees on‑premise.
Target Audience
Primary customers are AI product teams, SaaS developers, and enterprises that need to safely run LLM‑generated code for data transformation, tool creation, or feature extension, as well as organizations requiring on‑premise execution for compliance.
