Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

CLI for managing Vivarium sandboxes

Readme

@vivarium/cli

CLI for managing Vivarium sandboxes. Uses microsandbox to run the agent in a lightweight microVM with hardware-level isolation.

Install

npm install -g @vivarium/cli

Requires Node.js 22+ and macOS (Apple Silicon) or Linux with KVM.

Quick start

viv start --name my-app --token <HUB_TOKEN>

This pulls the vivarium OCI image, boots a microVM, and starts the agent. The agent connects to the hub and is ready to receive messages.

Commands

| Command | Description | |---------|-------------| | viv start | Create and start a new vivarium, or resume a stopped one | | viv stop [name] | Stop a running vivarium | | viv list | List all vivariums with status | | viv logs [name] | Stream sandbox output (-f to follow) | | viv shell [name] | Open an interactive shell in the sandbox | | viv status [name] | Show status, CPU, and memory usage | | viv upgrade [name] | Pull latest image and recreate (preserves data) | | viv remove [name] | Stop, delete sandbox, volume, and system service |

When only one vivarium exists, the name argument is optional.

Start options

--name <name>       Vivarium name
--token <token>     Hub authentication token
--hub-url <url>     Hub WebSocket URL (default: wss://app.vivarium.run/ws)
--api-key <key>     Anthropic API key (or set ANTHROPIC_API_KEY)
--port <port>       Host port (default: auto-assign from 3000-3099)
--image <image>     OCI image (default: ghcr.io/assaf-benjosef/vivarium:latest)
--cpus <n>          CPU cores (default: 2)
--memory <mib>      Memory in MiB (default: 2048)
--no-service        Don't install system service for auto-restart

How it works

Each vivarium runs inside a microsandbox microVM — a real VM with its own Linux kernel, booted from an OCI image in under a second. The agent process runs inside the VM with full access to /workspace (a persistent named volume).

On macOS, viv start also installs a LaunchAgent so the sandbox auto-restarts on reboot. On Linux, it creates a systemd user service.
