What is agenttier?
This Kubernetes platform provisions isolated, persistent sandbox environments for AI agents and developers. Each sandbox runs as a pod with dedicated persistent storage, network policies, and a browser-based terminal. The system includes a web dashboard, REST API, WebSocket terminal server, and Python/Go SDKs. Capabilities include running AI coding agents securely, on-demand developer environments, optional gVisor kernel isolation, multi-agent workflows, warm pod pools for fast startup, sandbox stop/resume/clone via CSI snapshots, and OIDC authentication with API keys. Deployment uses a single script for local clusters or AWS EKS with Terraform, plus a Helm chart for pre-built images. Licensed Apache-2.0, it requires Kubernetes 1.27+, a CNI with NetworkPolicy support, and a CSI storage driver.
