What is OPA Runner?

OPA Runner is a cross-platform desktop application that brings OPA files to life. Double-click any .opa file to open it in a sandboxed environment where the bundled prompt, data assets, and session history are loaded and executed by an AI agent.

How OPA Runner Works

Platform Support

OPA Runner is available for all major operating systems:

Platform Architectures Minimum Version
Windows x86_64, ARM64 Windows 7+
macOS Intel, Apple Silicon macOS 10.14+
Linux x86_64, ARM64 Modern distributions

Getting Started

  1. Download OPA Runner for your platform from the releases page
  2. Install the application using the platform-appropriate installer
  3. Open any .opa file — either double-click it or use File > Open from within the app
  4. Run the bundled prompt and watch the AI agent execute the task

Creating OPA Files

To create .opa files that you can open with OPA Runner, use one of the official language libraries:

  • Java — opa-java
  • JavaScript — opa-js
  • Python — opa-archive
  • PHP — opa-php
  • Ruby — opa-ruby

Or build archives manually following the specification — they’re just ZIP files with a specific structure.
