## Indicative from-price range

Indicative from-price range for self-hosting RAGFlow on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Managed documents (millions): 0.1; Daily content ingest (GB): 2; Peak concurrent queries: 20). 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:
- Managed documents (millions): 0.1
- Daily content ingest (GB): 2
- Peak concurrent queries: 20

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 (compact-rag-app). 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.

RAGFlow is an open-source retrieval-augmented generation engine from InfiniFlow that parses source documents with deep layout and structure understanding before feeding retrieved passages to an LLM. It layers in agent-style orchestration so answers can be traced back to cited excerpts from the original documents.

## What gets deployed with it

- Qdrant (required): Vector storage and retrieval dependency for the initial one-hop dependency model.

## Baseline topologies

- compact-rag-app: 1 node minimum; roles: ragflow
- app-plus-processing: 2 nodes minimum; roles: ragflow-api, ragflow-worker

## What drives the cost

- Managed documents (millions): Approximate source documents managed by the deployment.
- Daily content ingest (GB): Daily volume of new or reprocessed content entering the pipeline.
- Peak concurrent queries: Peak simultaneous retrieval or answer-generation requests.

## Frequently asked questions

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

Indicative from-price range for self-hosting RAGFlow on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Managed documents (millions): 0.1; Daily content ingest (GB): 2; Peak concurrent queries: 20). 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 RAGFlow?

The sizing inputs the calculator uses for RAGFlow are: Managed documents (millions); Daily content ingest (GB); Peak concurrent queries. Cost also depends on the number of servers and the provider chosen.

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

The smallest baseline topology in the calculator's profile for RAGFlow is compact-rag-app (1 server). Other baseline topologies: app-plus-processing (2 servers minimum). The reference range above is computed for 1 server.
