Description
Agent Substrate serves as an open-source runtime that facilitates the operation of isolated, stateful agent and code-execution sandboxes within Kubernetes environments. It effectively manages the lifecycle of actors and workers, allocates active workloads to a common pool of available resources, and has the ability to pause idle sandboxes while maintaining their memory and filesystem states for potential future use. Utilizing gVisor or Cloud Hypervisor microVM for isolation, these sandboxes incorporate unique identity and networking controls for each actor. This platform is specifically tailored for infrastructure and platform teams who are developing services for hosting agents, creating coding environments, and handling other tasks that may involve untrusted or sporadic execution. The primary framework is designed to be portable across Kubernetes, with Google Cloud providing specialized deployment tools optimized for GKE. Additionally, users can implement optional Filestore agent volumes to ensure that workspaces remain intact and accessible through suspension and resumption cycles, enhancing the reliability of the development environment. This versatility makes Agent Substrate an essential tool for modern cloud-native applications.
Description
SEAOTTER serves as a managed control plane specifically designed for the Hermes Agent on Google Cloud, providing isolated and consistently active agents without the need for VPS or SSH access. Users can easily create an agent via the dashboard, and within minutes, SEAOTTER sets up a dedicated namespace for each agent using a gVisor sandbox. The system allows for actions such as pausing, restarting, restoring, and reprovisioning through both API and user interface, all while offering integrated logs and metrics without the necessity of SSH access.
Sensitive information is securely managed in a write-only section and stored within Google Secret Manager, with Hermes loading the secrets at startup, ensuring that users should refrain from sharing keys in chat. Upon signing up, users can connect using an organization-scoped so_ MCP key from Cursor, Claude, or Codex, while Hermes acts as the operational hub featuring various tools, memory management, and cron capabilities, all hosted in the us-central1 region.
A trial period of seven days is available without requiring a credit card, allowing users to utilize one agent with limited resources (1 CPU / 4Gi / 8Gi). Following the trial, the cost for each always-on agent is $99 per month, with additional agents available for an extra $99 each, and custom solutions can be arranged through a consultation. This streamlined approach makes SEAOTTER an efficient choice for deploying agents in a managed cloud environment.
