ddev-langfuse 1.0.0 Adds Local Langfuse Stack to DDEV Projects

Developer Abhisek Mazumdar released version 1.0.0 of ddev-langfuse on 2 August 2026, adding a local Langfuse stack to DDEV projects. Abhisek introduced the add-on in a blog post as a way to run Langfuse observability, tracing, prompt management, and evaluation tooling on the same Docker network as the application under development. Although built with the Drupal AI ecosystem in mind, the add-on is not Drupal-specific and can be used by other applications able to send compatible tracing data to Langfuse.

The add-on runs Langfuse's web and worker services alongside PostgreSQL, ClickHouse, Redis, and MinIO within the DDEV project. On first installation, it generates the required secrets with openssl rand and automatically creates an organisation, project, administrator account, and API key pair. Credentials can be retrieved later through ddev langfuse-credentials, while the generated file containing secrets and API keys is automatically excluded from version control. The 1.0.0 release notes say the installation was tested end to end against a DDEV and Docker environment.

For Drupal development, Abhisek points to the AI, AI Agents, and Langfuse projects as the ecosystem he had in mind when building the add-on. The repository specifically documents configuring Drupal's Langfuse module to reach the local service at http://langfuse-web:3000 using the generated API credentials. Readers can find the release context in Abhisek's original post and installation, networking, and configuration details in the ddev-langfuse repository.
