What is Prometheus?
A pull-based monitoring platform that periodically scrapes metrics from instrumented targets over HTTP and stores them in a time-series database. It provides PromQL for querying metrics and integrates with Alertmanager for rule-based alerting and incident notifications.

Prometheus FAQ
Common questions about Prometheus, answered from independent, dated evidence.
What is Prometheus?
A systems monitoring platform that collects metrics from configured targets at regular intervals, evaluates alert rules using PromQL, and triggers notifications. It uses a dimensional data model with key-value labels for flexible metric analysis and dashboarding. It is indexed under Time-Series Databases.
Source: https://prometheus.io
Is Prometheus free to use?
Prometheus is open source, so it can be self-hosted and used at no licence cost. It is released under the Apache-2.0 licence. Pricing changes often, so verify at source before relying on it.
Source: https://prometheus.io
What platforms does Prometheus support?
Prometheus supports Windows, macOS, Linux and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.
Source: https://prometheus.io
Can Prometheus be self-hosted?
Yes. Prometheus can be deployed on-premise and self-hosted, so it does not have to run on the vendor's infrastructure.
Source: https://prometheus.io
What does Prometheus integrate with?
We have confirmed 24 integrations for Prometheus, including Amazon SNS, Discord, incident.io, Jira, Mattermost, Microsoft Teams, OpsGenie and PagerDuty, plus 16 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.

What security certifications does Prometheus have?
We have independently confirmed GDPR for Prometheus. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Prometheus not holding them. Always confirm compliance directly before you rely on it.
Is Prometheus open source?
Yes. Prometheus is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.

The vioscaleAI score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for Prometheus, not the verdict.
