# Integrations

> The coding agents that run the plugin, the agent frameworks the harness drives, and the trace platforms you can ground a simulation in.

Plurai Simulation plugs into three kinds of tools: the coding agent you run the plugin in, the framework your
agent is built on, and the observability platform that holds your production traces.

## Coding agents

The plugin installs from one marketplace and runs the same flows on each coding agent. Only the way you
install it and type a command differs. Claude Code, GitHub Copilot CLI and Codex CLI are all supported. Cursor support is coming soon.

> [card] [Claude Code](https://docs.plurai.ai/integrations/claude-code.md)
>
> The primary target. Commands start with `/`, for example `/simulate`.

> [card] [Codex CLI](https://docs.plurai.ai/integrations/codex-cli.md)
>
> Commands start with `$`, for example `$simulate`.

> [card] [Copilot CLI](https://docs.plurai.ai/integrations/copilot-cli.md)
>
> Commands carry the plugin name, for example `/plurai-simulation:simulate`.

## Agent frameworks

The harness (`simulate.py`) drives your agent without changing its source. Python agents run in-process;
Node agents run in their own runtime through a bridge.

> [card] [Python agent frameworks](https://docs.plurai.ai/integrations/agent-frameworks.md)
>
> LangGraph, Claude Agent SDK, Google ADK, CrewAI, OpenAI Agents SDK, LlamaIndex, Strands, LangChain, or no framework at all.

> [card] [Node agents](https://docs.plurai.ai/integrations/node-agents.md)
>
> Mastra, Vercel AI SDK, LangGraph.js, OpenAI Agents JS or a custom loop, through the Node bridge.

## Observability platforms

Plurai Simulation works natively with LangSmith, Langfuse, Arize and Braintrust. Ground the mock environment,
scenarios and evals in real production behavior, replay real conversations from the turn where they broke, and
record Runs back to the platform your team already uses.

> [card] [Observability platforms](https://docs.plurai.ai/integrations/trace-sources.md)
>
> Analyze traces from LangSmith and Langfuse, replay conversations from LangSmith and Arize, and record
> Runs to all four.

> [card] [Python SDK](https://docs.plurai.ai/sdk/overview.md)
>
> Use the `plurai` SDK directly, for CI or for a harness you write yourself.
