AI agents are all the rage right now and I’ve been wanting to test running AI-generated code locally. But most “agent runtimes” today are actually just running Docker locally or ask for my credit card if I want to test untrusted “agents” on their cloud-managed solution.
I built ERA with some hackathon friends — an open-source secure runtime that launches microVMs to execute code with true isolation. Some add-ons because we need it: we’ve got persistent storage and multi-language support as long as there’s a Docker image for it (we packed it with Python, Node, Ruby, Go, etc.).
Under the hood we use krunvm + Buildah to boot microVMs that behave like single-process containers with VM-grade isolation. Under THAT hood, it’s using libkrun which powers Firecracker.
