shuru offers a local-first microVM sandbox specifically designed for AI agents on macOS. It leverages lightweight Linux VMs powered by the Apple Virtualization.framework, ensuring near-native speed on ARM64 architecture without the need for Docker. This innovative tool is ephemeral by default, meaning every run starts from a clean root filesystem, allowing users to install and break anything without persistence unless explicitly saved.<h3>Key Features</h3><ul><li>Ephemeral by Default: Each session begins fresh, with nothing persisting unless saved, providing a clean slate for experimentation.</li><li>Checkpoints: Save disk states as named snapshots, enabling restoration, branching, and iteration akin to git commits.</li><li>Apple Silicon Native: Built on Virtualization.framework, it operates without an emulation layer, ensuring fast performance on ARM64.</li><li>Simple CLI: Easily run, checkpoint, and restore environments with straightforward commands.</li><li>Configurable Resources: Set CPUs, memory, and disk size per run or via configuration files for tailored performance.</li><li>Port Forwarding: Expose guest ports to the host, facilitating communication without network access.</li></ul>shuru is ideal for running AI-generated code in isolated environments, allowing agents to safely install packages, compile code, and use system tools. It supports parallel sandbox creation for reproducible evaluations and provides disposable Linux environments for testing, debugging, and prototyping. Installation is quick, requiring just a single command to get started.

neko is a small, single-binary AI agent runtime designed for constrained hardware like a Raspberry Pi Zero 2W or a low-end VPS.It runs an agent “gateway”, stores memory as plain markdown files (no database, no vector store), supports MCP tools over stdio, supports Agent skills, and can be controlled via Telegram or scheduled with cron jobs.Everything is intentionally simple and inspectable. Memory lives in files you can open, edit, grep, or commit.

Alright, you’ve got projects to run, Node versions to switch between, and tasks to automate. You don’t want a bloated tool or to keep bouncing between nvm and npm scripts. Shuru is here to simplify all that: a task runner with a built-in node version manager. It’s lightweight, written in Rust, and gets out of your way while making sure your tasks run smoothly.<h3>What’s Shuru?</h3>Shuru does two things:<ol><li>Manages Node.js versions per project.</li><li>Runs project-specific tasks defined in a simple config file.</li></ol>That’s it. No fancy features you’ll never use. It’s focused on making your workflow simpler by handling the stuff that’s usually a pain when switching projects — like making sure you're on the right version of Node and running the same commands every time.<h3>How to Install</h3>Linux/macOSInstallation is super easy:curl -s https://raw.githubusercontent.com/harshdoesdev/shuru/main/install.sh | sh
Windows<ol><li>Head over to the <a target="_blank" rel="noopener noreferrer nofollow" class="text-green-text rich-link break-all link-break" href="https://github.com/harshdoesdev/shuru/releases">Shuru GitHub releases</a> page.</li><li>Download the Windows executable.</li><li>Add it to your system's PATH for easy access.</li></ol>That’s it. You’re set up.<h3>Using Shuru</h3>You define your tasks and node version in a shuru.toml file at the root of your project. Here’s a basic example: <a target="_blank" rel="noopener noreferrer nofollow" class="text-green-text rich-link break-all link-break" href="https://github.com/harshdoesdev/shuru/blob/main/examples/simple-node-app/shuru.toml">a-simple-node-app</a>Shuru will make sure you’re using the specified Node.js version (v16.14.0 in this case) and run the tasks like npm install or npm run dev with a single command.<h3>Running Tasks</h3>Once your shuru.toml file is ready, you can run any task with:shuru &lt;task_name&gt; For example:shuru setup
Shuru will switch to the correct Node.js version (if necessary) and run the command npm install. Want to check the Node version your project is using? Just run this command:shuru version Shuru will switch to the right version of Node and give you the info in one go.<h3>Why Shuru?</h3>Shuru is all about simplicity and focus. It doesn’t try to replace task runners like Gulp or npm scripts. Instead, it’s a lightweight tool that:<ul><li>Manages your Node versions.</li><li>Automates running project-specific tasks.</li></ul>Nothing more, nothing less. If you want something that just works, Shuru is for you. Check it out on <a target="_blank" rel="noopener noreferrer nofollow" class="text-green-text rich-link break-all link-break" href="https://github.com/harshdoesdev/shuru">GitHub</a> and see if it fits your workflow.Give it a shot, contribute if you want, and simplify the way you run tasks across projects.
