# Developer Tools

> Learn about tools that support design, coding, testing, and monitoring in C3 AI development.

The C3 Agentic AI Platform includes a suite of tools to support application development across design, coding, data operations, and machine learning.

## Development environments

### C3 AI Studio

C3 AI Studio is the central development environment for building, testing, and operating applications on the platform. It provides a unified interface for:

* Modeling application logic, data flows, and pipelines using interactive visual tools
* Managing environments, packages, and runtime services across dev, staging, and production
* Investigating errors in data ingestion, transformations, job scheduling, or model execution
* Exploring application structure—including entity relationships, workflow dependencies, and UI components
* Monitoring job queues, compute utilization, and prediction throughput from a single dashboard
* Defining entities, rules, and workflows through guided editors, then extending them in code as needed

Studio surfaces real-time execution details alongside system configuration, making it easier to test changes, trace issues, and validate behavior as you iterate.

### C3 AI VS Code Extension

The C3 AI VS Code Extension integrates with Visual Studio Code to provide a robust development environment tailored for the C3 AI Platform.

Key features include:

* **Inline Documentation**: Hover over model elements or functions to view definitions and usage notes without leaving the editor
* **Error Checking**: Automatically detects issues in data models and application logic upon saving
* **Code Navigation**: Jump between references and definitions across the entire application package
* **Test Management**: Generate, run, and manage tests in isolation or batches, with results displayed in-line
* **Notebook Support**: Develop notebooks, commit them to your codebase, and reuse them across applications

### Managed JupyterLab service

For data scientists and ML engineers, the platform includes a managed JupyterLab environment preconfigured for experimentation and model development.

Features include:

* **Preloaded libraries**: TensorFlow, PyTorch, Prophet, Hugging Face, and more
* **Configurable compute**: Choose CPU or GPU runtimes with auto-shutdown for idle sessions
* **Code assist**: Use C3 Generative AI to explain code, suggest transformations, or fix bugs
* **Direct platform access**: Load and save data directly from platform-managed stores
