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
Pieces for Developers: Does Pieces store my data in the cloud?

Pieces stores captured data on-device by default, giving users granular controls to pause, disable or delete captures rather than relying solely on cloud storage.

Source
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
Pieces for Developers: Is there a free plan for Pieces?

Pieces does not offer a permanently free plan; new users instead get a 7-day free trial on any plan, which requires a credit card to start.

Source
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
Pieces for Developers: What does the Pro plan cost?

Pro is $18.99 per month billed monthly, with roughly a 25% discount available when billed yearly.

Enterprise costs $22.99 per month (or $69.99 per quarter) and adds organization-wide admin controls, approved AI providers, and governance over captured data.
