In plain words

Bastion provides isolated Linux virtual machines designed for running background coding agents. It's built for developers who need to execute code in a contained environment without affecting their main system. The product emphasizes isolation as its core feature, ensuring that automated coding tasks run safely within dedicated VMs while maintaining separation from production or local systems.

From the sources

curl -fsSL https://bastion.computer/install.sh | bash Run every coding agent in isolation Each coding agent runs in its own VM with full control over its development environment, from the filesystem to background processes. Orchestrate coding agents across a cluster of physical servers and run them asynchronously in the background. Initialize every agent from a schema-validated JSON template with no manual provisioning required. Run Bastion on any Linux machine with KVM support, from local workstations to cloud servers. { "agents" : { "opencode" : { "working_directory" : "/workspace/app" , "auth" : { "openai" : { "type" : "api" , "key" : "${{ secret.OPENAI_API_KEY }}" } }, "config" : {…from bastion.computer

  • Sub-millisecond VM sandboxes using CoW memory forkingMar 2026 · github.com · ▲311

    I wanted to see how fast an isolated code sandbox could start if I never had to boot a fresh VM. So instead of launching a new microVM per execution, I boot Firecracker once with Python and numpy already loaded, then snapshot the full VM state. Every execution after that creates a new KVM VM backed by a `MAP_PRIVATE` mapping of the snapshot memory, so Linux gives me copy-on-write pages automatically. That means each sandbox starts from an already-running Python process inside a real VM, runs the code, and exits. These are real KVM VMs, not containers: separate guest kernel, separate guest…

  • Run coding agents in microVM sandboxes instead of your host machineApr 2026 · github.com · ▲63

    Hi HN, we built SuperHQ, an open source app that runs AI coding agents in isolated microVM sandboxes instead of directly on your machine. Each agent gets its own VM with a full Debian environment. You mount your projects in, writes go to a tmpfs overlay so your host is never touched, and you get a diff view to accept or discard changes. API keys never enter the sandbox. We also just launched remote.superhq.ai which acts as a remote control for SuperHQ, allowing you to access your workspaces and agents from anywhere.

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  • Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
