Local development

Tools for the inner development loop.

Install the Catalyst skills in Claude Code, Codex, or GitHub Copilot, and have your agent build and deploy for you.

Connect your agent to the hosted Catalyst MCP server, with OAuth sign-in.

Scaffold and review Dapr Workflow and agentic applications with the Claude Code plugin.

Connect a .NET Aspire app host to Catalyst during local development and testing.

Inspect workflow executions and actor state during development. Language-agnostic.

Use diagrid dev run to connect a local app to Catalyst with tunnels, callbacks, and multi-app run files.

If you hit issues with the Diagrid CLI, the dashboard, or the Aspire integration, see Troubleshooting / FAQ.
