Langfuse
Indicative from-price range
Indicative from-price range for self-hosting Langfuse on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Daily traces or events: 50000; Trace retention period (days): 90; Peak dashboard queries: 10). From-price by provider, each the cheapest server in that provider's own shortlist: $24 on DigitalOcean (basic-2vcpu-4gb, 2 vCPU, 4 GB RAM, fra1); $49 on Google Cloud (e2-standard-2, 2 vCPU, 8 GB RAM, us-central1); $63 on Amazon Web Services (c9g.large, 2 vCPU, 4 GB RAM, us-east-1); $64 on OVHcloud (rise-1, 6 vCPU, 32 GB RAM, eu-west); $66 on Microsoft Azure (D2as_v7, 2 vCPU, 8 GB RAM, eastus); $66 on Hetzner (AX41, 6 vCPU, 64 GB RAM, eu-central); $262 on Servers.com (dl-01, 8 vCPU, 64 GB RAM, eu-west).

Methodology
This range is generated automatically from public provider price lists. It has not been reviewed by a person, it is not a quote, and it may differ from the total the calculator chooses for your own workload with its AI step. Method: the calculator's offer shortlist for the reference workload (the same ranking it builds before the AI step, up to 12 offers across providers; 12 here) is priced at its monthly list price in USD. The low end is the cheapest of the per-provider from-prices below and the high end is the median server of the combined shortlist, each multiplied by 1, the smallest baseline topology (single-node). The from-price for each provider applies the same method to that provider's own shortlist (the calculator's ranking restricted to that provider), so it is the cheapest server that ranking offers there, not a recommendation. Prices are taken from the price snapshot dated 2026-10-19; prices quoted in EUR are converted with the ECB reference rate dated 2026-10-19. Servers with fewer than 2 vCPU or less than 4 GB RAM are not priced. Only server rental list prices for the product's own servers are counted: dependencies, licences, support, traffic charges, taxes and setup fees are not included.

Langfuse is an open-source LLM engineering platform that gives teams tracing, evaluation, prompt management, and dataset tooling to debug and improve LLM-powered applications. It can be run as a managed cloud service or self-hosted on a team's own infrastructure.
What gets deployed with it
- PostgreSQL HA Cluster — required Primary store for Langfuse trace, span, score, and evaluation metadata.
- ClickHouse Cluster — required Analytics store for trace and event queries. Sized for compressed trace data derived from daily_traces × trace_retention_days.
- Redis Cluster — required Queue and cache layer for Langfuse background worker ingestion and operational support.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| single-node | 1 | langfuse |
| app-plus-workers | 2 | langfuse-web, langfuse-worker |
What drives the cost
- Daily traces or events
- Approximate LLM traces or events ingested per day across all projects.
- Trace retention period (days)
- How long traces and spans stay available before expiry. Drives total storage footprint.
