Yes, the v2 branch contains production code for Langfuse v2. (1)

Regarding Redis: You're correct that Redis is not required for Langfuse v2. Redis was introduced as a requirement in Langfuse v3. (1)

For Langfuse v2 local deployment, you only need:

• PostgreSQL database
• The Langfuse server container

To run Langfuse v2 locally using docker compose: (1)

# Clone the Langfuse repository
git clone https://github.com/langfuse/langfuse.git
cd langfuse
 
# Checkout V2 branch
git checkout v2
 
# Start the database and langfuse server
docker compose up

The v2 docker-compose.yml file should only include PostgreSQL and the Langfuse server - no Redis. (1) If you're seeing Redis connection errors on the v2 branch, this suggests there may be an issue with your local setup or you might be using configuration from v3.

Note: Langfuse v2 receives security updates only until end of Q1 2025. (1) (2) Consider planning an upgrade to v3 when feasible.

no. it has just given response from documentation. But the code in branch v2 is not in sync for local debugging for v2, branch code is v3 dev code. Ideally v2 branch should not have any v3 related changes.

@guptagaurav89 The v2 branch contains a few preparations for v3, but should with the default configuration within the docker-compose. How do you run it and which errors do you observe?

[guptagaurav89]

@Steffen911 Trying to run it using pnpm run dev command locally, db_url has been updated in .env file but .env.local.example has Redis related keys also.
worker:dev: 2026-01-28T14:59:06.398Z error Failed to initialize redis connection
Ideally v2 branch code should be separated before v3 preps to point to langfuse:2 docker image tag, is it not the case?

[Steffen911]

@guptagaurav89 The development setup includes redis configurations as this was the main thing we were targeting for development. I would recommend to run it using the docker compose and the corresponding image tags.

@Steffen911 If I need to modify something in v2 as per LICENSE, how to develop please suggest.
