Tools: New Clickhouse Acquires Langfuse 2026

Our goal continues to be building the best LLM engineering platform

If you’re reading this as a Langfuse user, your first question is probably: What does this mean for me?

Our roadmap stays the same, our goal continues to be building the best LLM engineering platform, and we remain committed to open source and self-hosting. There are no immediate changes to how you use Langfuse and how you can reach out to us.

What does change is our ability to move faster. With ClickHouse behind us, we can invest more deeply into performance, reliability, and our roadmap that helps teams build and improve AI applications in production.

This is the section we would want to read first, too.

Joining Clickhouse compresses years of operational learning into immediate, real customer benefits.

The longer version of how we got here is in our handbook.

Langfuse started the same way many LLM products start: we were building agents ourselves. And we constantly ran into the same problems.

Building LLM apps is easy to demo and hard to run in production. Debugging is different, quality is non‑deterministic, and the iteration loop is messy. When we did Y Combinator in early 2023, we saw this every week, both in our own projects and in what other founders in our cohort were working on.

So we built a duct tape version of what we wished existed: tracing and evaluation primitives that are easy to add, easy to self‑host, and actually useful for iterating.
