Agent Substrate open-sourced: agent runtime with 10x container density, sub-500ms resume
rakyll · x · 2026-09-21
- rakyll announced the open-source release of Agent Substrate, a secure-by-default agent execution runtime that runs on Kubernetes (2k GitHub stars already).
- Engineered for autonomous agents: millions of sandboxes at 10x higher density than standard container runtimes.
- Sub-500ms resume and 500+ suspend/resume activations per second — fast enough to suspend/resume per tool call; ships with a native zero-trust kernel. Not an officially supported Google product.
