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
Calljmp is a developer-first AI runtime for building and running long-lived, stateful agent workflows in production.
Unlike AI agent frameworks that focus mainly on authoring logic in code, Calljmp provides a managed runtime that handles execution concerns by default. This includes durable state persistence, pause and resume for human-in-the-loop workflows, safe retries with idempotency, and built-in observability across every step of an agent’s execution.
Calljmp is designed for teams using TypeScript who want to ship production-grade AI systems without stitching together queues, databases, custom state machines, and monitoring infrastructure. Developers write agent workflows as code, while the runtime guarantees reliable execution over time, even across crashes, restarts, and long waits.
Calljmp targets the gap between developer-first agent frameworks and heavy workflow engines, offering a practical path from prototype to production for real-world AI agents.
