Validate on the free Hobby tier before committing to a paid plan high success

The Hobby plan on Langfuse Cloud is free forever and includes core tracing, observability, prompt management, and even Prompt Experiments. Use this to fully validate fit with your stack before upgrading. You have no time pressure to pay until you hit a hard feature wall.

Self-hosted Langfuse OSS is free for core features. Before moving to Core ($29/month) or Pro ($199/month) on Cloud, calculate your internal DevOps cost for maintaining a self-hosted instance. For teams already running Hetzner or similar infrastructure, self-hosting may be net cheaper — but only if your team has the bandwidth to maintain it.

Langfuse Pricing FAQ

01 Can I self-host Langfuse for free?

You can self-host Langfuse's core OSS features for free. However, advanced capabilities — including Prompt Experiments, LLM Playground, Human annotation queues, and LLM-as-a-judge evaluators — require a paid commercial plan even on self-hosted deployments. The Core plan starts at $29/month and the Pro plan at $199/month.

02 Are prompt experiments included in the free Hobby plan?

On Langfuse Cloud, prompt experiments are available on the free Hobby plan. When self-hosting, however, prompt experiments are part of the commercial offering and are not included in the free open-source version — a distinction that has caught teams off guard.

03 Does Langfuse support AWS Bedrock?

Langfuse integrates with AWS Bedrock, but as of late 2024 the integration has known gaps: there is no pricing data in the default Bedrock model configurations and no playground integration. Teams running heavy Bedrock workloads should verify current integration status before committing.

04 How does Langfuse compare in price to LangSmith?

Langfuse is widely cited as a lower-cost alternative to LangSmith, with some users explicitly switching due to LangSmith's premium pricing. Langfuse's Hobby plan is free, Core is $29/month, and Pro is $199/month. LangSmith is described in community discussions as having 'premium pricing' relative to the observability space.

05 Is Langfuse really free to use?

Yes — the Hobby plan on Langfuse Cloud is free forever and includes core LLM observability, tracing, and prompt management. On Langfuse Cloud specifically, Prompt Experiments are also included on the free Hobby plan. Self-hosted OSS is also free for core features.

06 Do I need a paid plan to use Prompt Experiments when self-hosting?

Yes. Prompt Experiments are free on Langfuse Cloud (including the Hobby plan), but when self-hosting, they are part of the commercial offering and require a paid plan. You can run end-to-end experiments on Langfuse datasets via the SDK for free in the OSS version as an alternative.

07 What features are locked behind paid plans on Langfuse?

Paid plans (Core at $29/month and above) unlock LLM Playground, human annotation queues, and LLM-as-a-judge evaluators on both Cloud and self-hosted. When self-hosting specifically, Prompt Experiments also require a paid plan. The free Hobby tier covers core tracing, observability, and prompt management.
