R4 is a cloud-based secrets and password management platform for individuals, teams, and agent runtimes. Its Beetle product combines encrypted vaults with local decryption, scoped access, agent credentials, audit events, and secret retrieval through a web app, desktop app, Chrome plugin, mobile app, CLI, Node SDK, MCP server, and machine API. Individuals get vaults, projects, and device coverage across Windows, macOS, Linux, iOS, Android, Chrome, and the web.
The published plans show a freemium model with an Individual plan and a free option, while the listed starting price is $0.20 per GB-month, billed monthly. Individual highlights include end-to-end encrypted vaults, projects for grouping vaults, licenses, and agents, plus Chrome, desktop, and mobile apps. Teams adds multi-tenant workspaces, tenant members, security groups, inherited roles, scoped API keys for agent runtimes, usage monitoring, and audit events. Enterprise adds custom contracts and procurement, security review, dedicated onboarding, reserved usage and support terms, and bespoke integrations and compliance workflows.
R4 stands out when access needs to span people, projects, and agent runtimes. Scoped access can use tenants, security groups, projects, and direct sharing; agent credentials can use locally held runtime private keys; and retrieval is available through CLI, Node SDK, MCP, and machine API paths. Environment-variable export and usage metering extend the operational coverage. Choose R4 for encrypted, multi-device vault access with programmable retrieval and audit visibility. Teams that specifically require dynamic secrets or automated secret rotation should consider an alternative focused on those capabilities.
