# Self-host Langfuse v2

  This guide covers Langfuse v2. For the current version, see the [self-hosting
  documentation](/self-hosting). Langfuse v2 received security updates until end
  of Q1 2025. If you have any questions while upgrading, please refer to the [v3
  upgrade guide](/self-hosting/upgrade/upgrade-guides/upgrade-v2-to-v3) or open
  a thread on [GitHub Discussions](/gh-support).

Langfuse is open source and can be self-hosted using Docker. This section contains guides for different deployment scenarios.

## Deployment Options [#deployment-options]

The following options are available:

- Langfuse Cloud: A fully managed version of Langfuse that is hosted and maintained by the Langfuse team.
- Self-host Langfuse: Run Langfuse on your own infrastructure.
  - Production via Docker. Please follow the [deployment guide](/self-hosting/v2/deployment-guide) for more details and detailed instructions on how to deploy Langfuse on various cloud providers.
  - Locally or on a single VM via [Docker Compose](/self-hosting/v2/docker-compose).

## Architecture

Langfuse only depends on open source components and can be deployed locally, on cloud infrastructure, or on-premises.

## Agent Instructions

This page is part of the [Langfuse](https://langfuse.com) documentation, published as plain Markdown for AI agents. Every page is available as Markdown by appending `.md` to its URL, or by sending an `Accept: text/markdown` header. This page: `https://langfuse.com/self-hosting/v2.md`.

### Querying these docs

If the answer is not on this page, query the documentation instead of guessing:

- **Semantic search** across all Langfuse docs, returning an answer with the relevant pages and excerpts. Ask a specific, self-contained question:

  ```bash
  curl -sG "https://langfuse.com/api/search-docs" --data-urlencode "query=How do I trace a LangGraph agent?"
  ```

- **Index of every page**: <https://langfuse.com/llms.txt>, with per-section indexes [llms-docs.txt](https://langfuse.com/llms-docs.txt), [llms-integrations.txt](https://langfuse.com/llms-integrations.txt), and [llms-self-hosting.txt](https://langfuse.com/llms-self-hosting.txt).

### Before writing Langfuse code

- **Install the [Langfuse Agent Skill](https://langfuse.com/docs/api-and-data-platform/features/agent-skill).** It encodes Langfuse's own best practices for instrumentation, prompt management, and evaluation, and materially improves results.
- **Read [What does a good trace look like?](https://langfuse.com/docs/observability/best-practices.md)** before instrumenting an application.
- **Verify endpoints, parameters, and response fields** against the [API reference](https://api.reference.langfuse.com) instead of inferring them from code examples.
- **Use the [Langfuse CLI](https://langfuse.com/docs/api-and-data-platform/features/cli)** (`npx langfuse-cli api <resource> <action>`) to read or write traces, prompts, datasets, and scores from the terminal.
