A good fit for

• Individual developers and AI coding agents who want fast, real-environment testing without deploying or waiting for CI.
• Engineering teams sharing a Kubernetes cluster who need collaboration features, session management, and organizational governance.

Know the limitations

• The open source version does not include the mirrord Operator, so it lacks session management and traffic isolation needed for team environments.
• The Enterprise plan is required to run AI agents in the cloud, CI environments, and preview environments with concurrent sessions; the Team plan only supports local AI agents.

What you can do

• Developers write and test code instantly against real services from their IDE or terminal without deploying or using mocks.
• Platform teams manage a single shared cluster with built-in isolation and access controls, reducing infrastructure costs and operational overhead.
• Engineering leaders accelerate shipping by validating every change against real infrastructure before merging, cutting feedback loops from hours to seconds.

Features

• Connects local code to live Kubernetes clusters without building container images or deploying, by proxying traffic, environment variables, and files between local processes and the cluster.
• Supports unlimited concurrent sessions with built-in isolation, RBAC, and traffic routing to prevent conflicts when sharing a single cluster among multiple developers and AI agents.
• Includes mirrord Operator for managing sessions, RBAC, traffic routing, and isolation for team environments sharing a Kubernetes cluster.
