Benefits

  • Remote JavaScript Execution

    Instantly run your JavaScript code in the cloud, using the fast and modern Bun runtime.

  • Automatic Dependency Handling

    Import NPM-style packages with require directly in your code, and specify any needed system dependencies for automatic installation.

  • Flexible Output Retrieval

    Use a top-level return or set a global ‍variable in your code to receive structured results back from the API.

  • Secure & Isolated Environment

    All code runs in a sandboxed Linux container with strict memory and execution time limits for safety and reliability.

Use cases

Rapid Prototyping & Testing

Experiment with or demonstrate JavaScript code without any setup—perfect for sandboxing ideas, trying libraries, or teaching.

Serverless Scripting & Dynamic Endpoints

Execute on-the-fly scripts for automation, data transformation, or workflow customization without infrastructure management.

Resource Offloading

Run heavy, complex, or dependency-heavy JavaScript workloads in the cloud, saving local resources and avoiding environment conflicts.
