# The Humanloop API stops working

Calls to the Humanloop API stopped working on September 8, 2025.

## What to use instead

Move prompt management, evaluations, and logging to an alternative LLM ops platform, such as Langfuse, LangSmith, or Braintrust, and remove the Humanloop client. Because there is no successor product, teams must decide which replacement platform to adopt.

Humanloop shut down with no successor product: choosing the replacement platform is the team's call.
