The short version

  • Each has a real cost: Prometheus not suitable for per-request billing as collected data lacks 100% accuracy; Twingate the control plane is proprietary and hosted, so it cannot be run inside your own boundary and a vendor outage prevents new connections from being established even though the connectors are yours.
  • They diverge on capability: Prometheus covers Multi-dimensional Data Model, Twingate covers Outbound only connectors.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Prometheus

  • Not suitable for per-request billing as collected data lacks 100% accuracy
  • Hard limit on scrape body size; large responses cause scrape failure
  • Per-scrape sample limit enforced; exceeding limit marks targets as failed
  • Not designed for long-term durable storage; optimised for metrics collection

Twingate

  • The control plane is proprietary and hosted, so it cannot be run inside your own boundary and a vendor outage prevents new connections from being established even though the connectors are yours.
  • Every device needs the client installed and running, so unmanaged machines, appliances and third parties who will not install software are awkward to accommodate.
  • Pricing is per user per month, so an organisation with many occasional contractors pays full seats for accounts that connect twice a month.
  • Connections are client initiated, so server initiated flows back to a user device, and protocols that need arbitrary inbound reachability, do not fit the model.
  • It replaces remote access but not site to site networking, so an organisation that also needs offices and datacentres meshed together still runs a second network product alongside it.

Answered from the vendors’ own pages

Prometheus: What does Prometheus cost?

Prometheus is completely free and open source. There are no pricing tiers or paid plans. The entire project is licensed under Apache 2 and hosted on GitHub.

Source
Twingate: Can I self host it?

No. Connectors run in your network but the control plane is a hosted service, which is the main structural difference from the open source mesh tools.

Prometheus: Is Prometheus commercial software or free?

Prometheus is 100% open source and community-driven. It is a CNCF graduated project with no commercial restrictions or licensing fees.

Source
Twingate: Does it replace a site to site VPN?

No. It is remote access from users to resources. Connecting networks to each other is a different product category.

Prometheus: How is Prometheus licensed?

Prometheus is licensed under the Apache 2 License, which permits free use, modification, and distribution for commercial and non-commercial purposes.

Source
Twingate: What happens if Twingate is unavailable?

Established sessions may continue, but new connections depend on the hosted service to broker them, so plan a break glass path for administrators.

Twingate: Is the free tier usable for a small team?

For a handful of users and a small number of remote networks, yes. Group based policies and posture checks are the practical reason to move up.
