Hidden Costs Breakdown

1

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.

reddit

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.

2

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.

3

Self-Hosted Prompt Experiments Require Paid Commercial Plan

medium addon

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.
