Plural is an AI tool for infrastructure work, presented for platform and DevOps teams. It can upgrade clusters, resolve incidents, patch vulnerabilities, optimize costs, and execute changes across code, clusters, and cloud. Its project-scoped Workbenches package an AI agent’s prompt, capabilities, tools, and automation triggers for infrastructure operations.

Pro starts at $450/mo for one cluster, with each additional cluster at $250/mo, and includes a 30-day free trial. Pro uses shared Plural infrastructure; Enterprise offers shared, dedicated, or on-prem hosting.
