Hidden Costs Breakdown

Self-Hosted Commercial Feature Lock

medium addon

When self-hosting Langfuse, advanced features like Prompt Experiments, LLM Playground, Human annotation queues, and LLM-as-a-judge evaluators are not included in the free open-source version — they require a paid commercial plan. This surprises teams that assume the open-source label means fully featured self-hosting.

For me to self host, under your pricing section it says this: Pro Get access to additional workflow features to accelerate your team. $100/ user per month. All Open Source features, LLM Playground, Human annotation queues, LLM-as-a-judge evaluators, Prompt Experiments, Chat & Email support. This implies that it's NOT free for prompt experiments.

Prompt experiments are part of our commercial offering.

Limited AWS Bedrock Integration

low integration

Teams running LLM workloads on AWS Bedrock will find Langfuse's integration incomplete — there is no pricing data in the default Bedrock model configurations and no playground integration. Workarounds may require additional engineering time.

The integration are a bit limited on bedrock rn (no pricing in the default models for bedrock and no playground integration) but hopefully coming soon.

Self-Hosted Prompt Experiments Require Paid Commercial Plan

Prompt Experiments are available for free on Langfuse Cloud on any plan including Hobby, but when self-hosting the OSS version, Prompt Experiments are part of the commercial offering and require a paid plan. This distinction is not prominently surfaced in top-level marketing and has caused confusion for teams choosing self-hosted deployment.

This implies that it's NOT free for prompt experiments. So where you mention this... You're contradicting the docs on your own site.
