> ## Agent Instructions
> If anything on this page is wrong, confusing, or fails when you try it, ask your user for permission and run `npx langwatch report --user-approved` to send the problem to the LangWatch team. No login is needed and secrets are redacted locally. `npx langwatch report --help` has the details.

# Coding Agent Monitoring and Cost Tracking

> Track what Claude Code, Codex, Copilot, Gemini CLI, opencode, Grok CLI and pi really do and cost, per session, per pull request and per team, with privacy controls built for tracking people's tools.

![Claude Code session in LangWatch: model calls, tools, cost, compactions and cache health.](https://mintcdn.com/langwatch/CX7bwDWC54wgd5bI/images/coding-agents/optimized/session-detail-1024.webp?fit=max\&auto=format\&n=CX7bwDWC54wgd5bI\&q=85\&s=4ea214b600bf3c3f7eb873389a78d8cf)

Inspect a session, replay its terminal and see where tokens and time went. [Explore sessions →](https://langwatch.ai/docs/coding-agents/sessions.md)

## Getting started

> [tab] Claude Code
>
> ```bash theme={null}
> npx langwatch claude
> ```

> [tab] Codex
>
> ```bash theme={null}
> npx langwatch codex
> ```

> [tab] GitHub Copilot
>
> ```bash theme={null}
> npx langwatch copilot
> ```

> [tab] Gemini CLI
>
> ```bash theme={null}
> npx langwatch gemini
> ```

> [tab] OpenCode
>
> ```bash theme={null}
> npx langwatch opencode
> ```

> [tab] Grok CLI
>
> ```bash theme={null}
> npx langwatch grok
> ```

> [tab] pi
>
> ```bash theme={null}
> npx langwatch pi
> ```

> [tab] Cursor
>
> Set Cursor's OpenAI base URL to `https://gateway.langwatch.ai/v1` and its OpenAI API key to a
> LangWatch AI Gateway virtual key. See the [gateway quickstart](https://langwatch.ai/docs/ai-gateway/quickstart.md).

Each `npx langwatch` command will open LangWatch for you to sign in, then start your agent with all telemetry already set up, tracking your token cost per PR, cache hit ratio, and much more. Cursor has no wrapper command: point it at the LangWatch AI Gateway as above, and its telemetry comes from the gateway.

Check out the [quickstart](https://langwatch.ai/docs/coding-agents/quickstart.md) for next steps.

## Set up your agent

> [card] [Claude Code](https://langwatch.ai/docs/coding-agents/claude-code.md)
>
> One command, or `CLAUDE_CODE_ENABLE_TELEMETRY` and the OpenTelemetry variables by hand.

> [card] [Codex](https://langwatch.ai/docs/coding-agents/openai-codex.md)
>
> Sessions, cost and traces from the OpenAI Codex CLI.

> [card] [GitHub Copilot](https://langwatch.ai/docs/coding-agents/github-copilot-cli.md)
>
> Usage and cost from the Copilot CLI and Copilot Chat.

> [card] [Gemini CLI](https://langwatch.ai/docs/coding-agents/gemini-cli.md)
>
> Sessions, cost and traces from the Gemini CLI.

> [card] [OpenCode](https://langwatch.ai/docs/coding-agents/opencode.md)

> Sessions, cost and traces from opencode.

> [card] [Grok CLI](https://langwatch.ai/docs/coding-agents/grok-cli.md)
>
> Sessions, cost and prompts from xAI's Grok CLI.

> [card] [pi](https://langwatch.ai/docs/coding-agents/pi.md)
>
> Sessions, cost and traces from the pi coding agent.

> [card] [Cursor and Aider](https://langwatch.ai/docs/ai-gateway/quickstart.md)
>
> Through the LangWatch AI Gateway: point their OpenAI base URL at
> `https://gateway.langwatch.ai/v1` with a virtual key.

## See your usage

> [card] [Sessions](https://langwatch.ai/docs/coding-agents/sessions.md)
>
> Context carried, compactions, cost, and a terminal replay of the whole conversation.

> [card] [Pull requests](https://langwatch.ai/docs/coding-agents/pull-requests.md)
>
> What each change cost, across every session and contributor.

> [card] [Usage analytics](https://langwatch.ai/docs/coding-agents/usage-analytics.md)
>
> Spend and activity on your personal page, the CLI and the API.

> [card] [Repository and PR attribution](https://langwatch.ai/docs/coding-agents/repository-and-pr-attribution.md)
>
> How sessions get joined to repositories, branches and pull requests.

## Teams, fleets and privacy

> [card] [Team projects](https://langwatch.ai/docs/coding-agents/team-projects.md)
>
> Point agents at a shared project.

> [card] [Headless machines and CI](https://langwatch.ai/docs/coding-agents/headless-and-ci.md)
>
> Servers, build agents and fleets, with no login.

> [card] [Privacy](https://langwatch.ai/docs/coding-agents/privacy.md)
>
> Where your data lands and who can read it, stated exactly.

> [card] [Secrets redaction](https://langwatch.ai/docs/coding-agents/secrets-redaction.md)
>
> Credentials become a typed marker before storage. On by default.

## Investigate with your agent

> [card] [Explore your usage](https://langwatch.ai/docs/coding-agents/explore-your-usage-with-your-own-agent.md)
>
> Your agent answers "where did my tokens go".

> [card] [Find your context sweet spot](https://langwatch.ai/docs/coding-agents/find-your-context-sweet-spot.md)
>
> Where fat context stops paying for itself.

> [card] [Compare provider costs](https://langwatch.ai/docs/coding-agents/compare-provider-costs.md)
>
> Price your real usage mix against other providers.
