## 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).

Reference workload:
- Daily traces or events: 50000
- Trace retention period (days): 90
- Peak dashboard queries: 10

Price snapshot: 2026-10-19. Currency: USD. FX snapshot: 2026-10-19.

Configuration: Low end: 1 x basic-2vcpu-4gb (DigitalOcean, 2 vCPU, 4 GB RAM, about $24 per server per month). High end: 1 x rise-m (OVHcloud, 12 vCPU, 64 GB RAM, about $112 per server per month).

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

- single-node: 1 node minimum; roles: langfuse
- app-plus-workers: 2 nodes minimum; roles: 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.

## Frequently asked questions

### How much does it cost to self-host Langfuse?

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). This is an automatically generated indicative figure from public price lists (price snapshot 2026-10-19), not a quote.

### What drives the cost of self-hosting Langfuse?

The sizing inputs the calculator uses for Langfuse are: Daily traces or events; Trace retention period (days). Cost also depends on the number of servers and the provider chosen.

### What is the minimum number of servers for Langfuse?

The smallest baseline topology in the calculator's profile for Langfuse is single-node (1 server). Other baseline topologies: app-plus-workers (2 servers minimum). The reference range above is computed for 1 server.
