It’s back! Starting Monday, November 3rd, we’re dropping a new feature every single day for five days.

All launches

This launch brings deeper agent insights from your agent applications, improved team collaboration, a big leap in experimentation/evaluation, and more ways to integrate with your favorite tools and frameworks.

We’ll unwrap a new feature each day:

Day 1: New Filters for Tables and API

Many users have millions of traces and observations. We’ve made it easier to filter and search for the data you need.

Learn more about filters in the UI and in the API

Day 2: Collaborate with your team directly in Langfuse

Comments now support @mentions and emoji reactions, making it easier to collaborate with your team directly in Langfuse. Tag teammates to bring their attention to specific sessions, traces, observations, or prompts, and use reactions to quickly acknowledge insights without adding another comment.

We teamed up with Mixpanel to integrate LLM-related product metrics into your existing Mixpanel dashboards. This integration makes it easy to combine your regular product analytics with the LLM-specific metrics that Langfuse generates.

Get started with the Mixpanel integration here
