CAMBRIDGE, Mass., Nov. 10, 2026 (GLOBE NEWSWIRE) — Solo.io, the leading provider of AI-ready infrastructure, today announced the general availability of its enterprise releases of Agent Substrate and kagent. Agent Substrate establishes a new infrastructure layer for agentic runtimes, combining serverless scale, sandbox isolation, and governed connectivity. kagent adds the developer experience for building and managing agents, tools, and skills. Launch customers, including OutSystems and Swissquote, are already running this infrastructure in production.
Agents are the next major workload for Kubernetes. To support them, the platform must evolve to handle the scale of individual agent sessions, each carrying its own state and context across multiple turns. At tens of millions of sessions, a dedicated pod for each one ties up resources while agents wait on models, tools, or human input. Agent Substrate introduces an execution model that suspends idle sessions and resumes them on demand, allowing enterprises to scale on the Kubernetes infrastructure they already operate.
Agent Substrate introduces the actor as the fundamental runtime unit for agents. Each actor brings an agent session together with two mandatory controls: a sandbox that isolates execution and a gateway that governs who can reach it and what it can access. State, identity, and access controls stay with the actor as the compute underneath changes, making isolation and governance integral to every session.
“Agent Substrate is trying to do for agentic workloads what kubernetes did for traditional deployments – to make the orchestration of them a non-issue. This layer is necessary but it’s not interesting for most agentic apps. Our goal is to make the problem go away, so people can focus on more interesting problems. Kubernetes itself is the perfect platform to build up from – it’s everywhere and it’s very well understood. When it comes to critical infrastructure, open always wins,” said Tim Hockin, Distinguished Software Engineer Kubernetes and GKE, Google.
Solo’s enterprise distributions of Agent Substrate and kagent deliver a supported agent runtime with agentgateway as the actor’s gateway, enforcing identity and policy controls on ingress and egress. kagent provides the developer experience for building and managing agents, tools, and skills, with enterprise capabilities for granular access control, agent tracing, infrastructure monitoring, and evaluations built from real execution traces. Enterprise support and deployment options, including air-gapped installations, help teams operate this infrastructure in environments with strict security and operational requirements.
Solo has partnered with engineering teams at OutSystems and Swissquote to bring agentic infrastructure into production, addressing the scale, security, and governance requirements of enterprise agent deployments.
“We operate a large, multi-tenant platform where our customers expect enterprise-grade resilience and scale. With the number of agents we expect to support, running a dedicated, always-on pod for every agent simply isn’t possible. Agent Substrate gives us sandboxed runtimes that suspend when idle and resume on demand. kagent and agentgateway build on that foundation with the APIs, lifecycle management, and gateway controls we need to integrate agents into our platform. Our partnership with Solo’s team has been critical to bringing Agent Substrate, kagent, and agentgateway into production on our timeline,” said Ebenezer Schubert, VP Engineering, OutSystems.
“We operate a sovereign AI stack, with full control over inference, infrastructure and the AI lifecycle. Solo’s enterprise kagent and Agent Substrate provide infrastructure-level isolation and security, while delivering the low latency required by our most sensitive agents. Our Codename Diego financial-crime investigation agents and MCP servers are already running in production on kagent GA. In a multi-jurisdictional regulated environment, security, resilience and explainability are non-negotiable. The joint engineering work with Solo has been outstanding,” said Andrew Boswell, Head Information Technology, Swissquote.
As a co-maintainer of the Agent Substrate project with Google, Solo is leading the development of the open-source foundation for agentic workloads. The community’s release of Agent Substrate 1.0 marks a significant milestone in agentic infrastructure, building on six months of momentum with more than 6,000 GitHub stars and over 100 contributors from more than 40 organizations. To help the community and customers plan their production rollouts, Solo has distilled its experience with performance and scale testing for GA into a calculator available on the kagent project site. The tool helps users size their environments and set service-level objectives for running Agent Substrate at scale.
“The next generation of applications will be agents. The infrastructure they need is being defined right now, and the choices we make will shape how enterprises run for years to come. Agent Substrate and the actor model are the foundation for that shift. We’re building for a world where agents carry out work across every part of an organization, with isolation and control built into the infrastructure from the start. Our customers are already showing what that future looks like in production,” said Idit Levine, founder and CEO of Solo.io.
