Answered from the vendors’ own pages

HashiCorp Vault: Does HashiCorp Vault have a free version?

Yes. The open-source Community Edition is completely free and includes core secrets management, dynamic secrets, and encryption as a service. It is self-hosted with no licensing fees or secret count limits, but lacks enterprise features like namespaces, disaster recovery replication, and Sentinel policies.

Source
VictoriaMetrics: Is VictoriaMetrics free?

The open-source version is free with no data limits. An enterprise edition and cloud service are paid.

HashiCorp Vault: Can I use HashiCorp Vault in production?

The Community Edition is suitable for non-production environments and small teams. For production deployments, organizations typically use HCP Vault Dedicated (managed cloud service starting at approximately 22 USD per month) or Vault Enterprise with custom pricing that includes disaster recovery, performance replication, and 24/7 support.

Source
VictoriaMetrics: Does it replace Prometheus?

It can, but most teams keep Prometheus for scraping and use VictoriaMetrics as the long-term store behind it.

HashiCorp Vault: What are the main integrations available?

Vault integrates with AWS, Azure, Google Cloud, Active Directory, Okta, and 80+ other platforms. It supports dynamic credential generation for cloud providers, database systems, and identity services, enabling centralized secret management across multi-cloud infrastructure.

Source
VictoriaMetrics: Is PromQL fully supported?

Very nearly. It implements PromQL and extends it with MetricsQL, though a small number of edge-case behaviours differ.

HashiCorp Vault: Does Vault work offline?

Vault requires network connectivity to function as it is a centralized secrets management server. However, it can be deployed on-premises for air-gapped environments, and clients can cache short-lived tokens for temporary offline access once authenticated.
