# Simultaneous

> Run agentic operators across execution environments with a unified API

### What is Simultaneous?

Simultaneous is a platform and Python SDK for running agents on infrastructure providers like Browserbase via a single, consistent API. It includes:

* Unified HTTP API for auth, projects, API keys, sessions, and agents
* Python SDK (`SimClient`, `BrowserClient`) for defining and running agents
* CLI (`sim`) for authentication and project/agent management
* Web dashboard (optional) for visibility
