## Indicative from-price range

Indicative from-price range for self-hosting Keycloak on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Monthly active users: 5000; Peak auth requests per second: 50; Number of realms: 1; Session profile: mixed). 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:
- Monthly active users: 5000
- Peak auth requests per second: 50
- Number of realms: 1
- Session profile: mixed

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.

Keycloak is an open-source identity and access management server that issues tokens over OpenID Connect and SAML 2.0 for applications it fronts.

## What gets deployed with it

- PostgreSQL HA Cluster (required): Draft first dependency target for Keycloak session and realm metadata persistence.

## Baseline topologies

- single-node: 1 node minimum; roles: keycloak
- ha-cluster: 2 nodes minimum; roles: keycloak

## What drives the cost

- Monthly active users: Users across all realms who sign in at least once during a typical month.
- Peak auth requests per second: Peak login, token refresh, and token validation request rate across all realms.
