R4

What R4 is

R4 describes itself as a full-stack license and secret management platform. Beetle manages encrypted passwords, licenses, and secrets for people and agents, while Pincer supports license acquisition and lifecycle workflows for marketplace, contract, and renewal operations. A unified control plane covers agents, vaults, and licenses, with identity-aware access, human-approved scopes, and audit-ready events. Agent runtimes can retrieve shared vault items and decrypt secrets locally through the MCP server, SDK, or machine API. R4 says vault field values are end-to-end encrypted and decrypted locally; vault names, item names, field labels, and website metadata are not end-to-end encrypted. The agent runtime’s private key remains on its host, while R4 stores the matching public key and rotation metadata. The cloud service documents a machine API and links to agent quickstart, CLI, SDK, and API documentation. The platform is in private beta, and the company invites users to request access. Pricing is usage-based, with listed free monthly tiers for secret access and write events, average active secret values, binary backup storage, and data transfer. Paid usage starts at $0.20/mo. Listed platforms include web, Windows, macOS, Linux, iOS, and Android.
