Prometheus
Indicative from-price range
Indicative from-price range for self-hosting Prometheus on 1 server: about $24 to $112 per month (USD), as of 2026-10-19, for the reference workload (Local retention window (days): 15; Active series (millions): 1; Scrape targets: 500; Scrape interval (seconds): 15). 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

- Scrape interval (seconds): 15
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-tsdb). 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 Prometheus for your own workloadMarkdown versionFor AI agents (llms.txt)
Prometheus is an open-source systems monitoring toolkit that pulls time-series metrics from instrumented targets over HTTP and stores them locally, offering its own PromQL language for querying and alerting.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|
| single-node-tsdb | 1 | prometheus |
| ha-scraper-pair | 2 | prometheus |
| remote-write-agent | 1 | prometheus-agent |
What drives the cost
- Local retention window (days)
- Number of days Prometheus should keep TSDB data on local storage.
- Active series (millions)
- Approximate active time series count handled by the deployment.
- Scrape targets
- Number of scrape targets polled on the configured interval.
