Langflow
Indicative from-price range
Indicative from-price range for self-hosting Langflow on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Concurrent flow executions: 10; Active flow builders: 5). 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
- Concurrent flow executions: 10

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.

Size Langflow for your own workloadMarkdown versionFor AI agents (llms.txt)
Langflow is an open-source, low-code visual builder for constructing LLM-powered agents and RAG workflows by dragging and connecting components on a flow-based canvas. It is built on top of Python AI libraries and can export flows for use as APIs or embedded applications.
What gets deployed with it
- PostgreSQL HA Cluster — required Langflow persists flow definitions, execution history, and user credentials in PostgreSQL.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| single-node | 1 | langflow |
| ha-pair | 2 | langflow-api |
What drives the cost
- Concurrent flow executions
- Expected peak number of simultaneously executing AI flows or pipelines. Drives CPU and worker memory planning.
- Active flow builders
- Number of users concurrently editing or testing flows in the visual builder. Affects API server and UI resource needs.
