FAQ
You can view the public example project or sign up for a free account to try Langfuse with your own data. The Hobby plan is completely free and does not require a credit card.
Yes, Langfuse is open source and you can self-host Langfuse for free. Use docker compose to run Langfuse locally, or use one of our templates to self-host Langfuse in production on Kubernetes. Check out the self-hosting documentation to learn more.
A billable unit in Langfuse is any tracing data point you send to our platform — this includes the trace (a complete application interaction), observations (individual steps within a trace: Spans, Events and Generations), and scores (evaluations of your AI outputs). For a detailed explanation and an example, see our Langfuse Billable Units docs.
Our graduated pricing means you pay different rates for different volume tiers. The first 100k units are included in paid plans, then you pay $8/100k for units 100k–1M, $7/100k for 1M–10M units, $6.5/100k for 10M–50M units, and $6/100k for 50M+ units. This ensures you get better rates as you scale up your usage. Use the pricing calculator to estimate your bill.
Data access is set by your plan and determines how many days of historic data you can view (Hobby: 30 days, Core: 90 days, Pro and Enterprise: 3 years). Older data is still stored and becomes accessible again when you upgrade. Data retention is a separate, opt-in feature on Pro and Enterprise that permanently deletes data after a custom period. See data access vs. data retention.
The primary way to reduce your Langfuse Cloud bill is to reduce the number of billable units that you ingest. We have summarized how this can be done here. Additionally, with our new graduated pricing model, you automatically get lower rates per 100k units as your volume increases.
On a representative workload, Langfuse Cloud is cheaper than LangSmith, Braintrust, Arize, and Datadog Agent Observability. Open the editable pricing comparison sheet to fill in your own assumptions and check the numbers for your workload. For product-by-product differences, see the comparison pages. Langfuse is also open source, based on OpenTelemetry for interoperability, self-hostable at the same scale as Langfuse Cloud, and model- and framework-agnostic.
You get one bill each month. We charge your Core, Pro, or Team plan at the start of the month. We charge for your usage at the end of the month. The bill you get at the start of the month shows two things: the plan cost for the new month and the usage from last month.
Yearly commitments are always available for Enterprise; Core, Pro, and Teams customers can also choose a yearly commitment if they meet the minimum contract value threshold.
A Langfuse Cloud Credit is a prepaid unit of credit, equal to one (1) US dollar, to be applied to a customer's use of Langfuse Cloud. Credits are drawn down according to the then-current pricing at langfuse.com/pricing. Langfuse Cloud Credits only apply to customers with a committed spend contract for Langfuse Cloud. If you have questions about your credit balance, drawdown schedule, or committed spend contract, please contact your account team. If you use Langfuse Cloud on a Pay-as-you-Go basis, Langfuse Cloud Credits do not apply to you.
Yes, you can configure spend alerts to receive email notifications when your organization's spending exceeds predefined monetary thresholds.
