24 alternatives to Rootless Containers/Pods that run systemd, Docker, and even Kubernetes

Hi HN, this is Cesar and Rodny, developers of an open-source container runtime called Sysbox, and co-founders of a startup called Nestybox (YC S20). We launched on HN almost a year ago and got excellent feedback then (https://news.ycombinator.com/item?id=24084758). Happy to say that over the past year, Sysbox has continued to gain traction, particularly for securing containers in production, CI/CD, and containerized dev environments. We wanted to announce an important new feature: integration between Sysbox and Kubernetes. As a quick refresher, Sysbox is a "runc" that…

Sysbox is an open-source container runtime that enables rootless containers to run system software like systemd, Docker, and Kubernetes alongside traditional microservices. It enhances container isolation through Linux… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Rootless Containers/Pods that run systemd, Docker, and even Kubernetes launched in 2021; newer entries below may have overtaken it.

    Devbox is a command-line tool that lets you easily create isolated shells and containers. You start by defining the list of packages required by your development environment, and devbox uses that definition to create an isolated environment just for your application. In practice, Devbox works similar to a package manager like yarn – except the packages it manages are at the operating-system level (the sort of thing you would normally install with brew or apt-get). See it in action: https://youtu.be/WMBaXQZmDoA

    ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

  3. 3DC

    I've been frustrated with dependency hell and clutter on my VPS from dev, so I built Devbox: a lightweight, open-source CLI tool that spins up isolated development environments using Docker. Each project runs in its own container, but your code stays in simple flat folders on the host machine—no messing with volumes or sync issues. Environments are disposable, so you can nuke and recreate them without losing your work. Key features: - Instant setup: `devbox init my-project` and you're in a fresh env with `devbox shell`. - Configurable via JSON: Define packages, services, and more in a…

    Signadot▲187

    Hi again HN, we’re Arjun and Anirudh, founders of Signadot (YC W20). Signadot helps teams developing microservices test their changes using lightweight environments called “Sandboxes”. We use a relatively new approach, using traffic labeling (using OpenTelemetry) and request routing (using a Service Mesh) to isolate environments in a shared Kubernetes cluster. Today, we’re launching a new feature to help developers with local testing of microservices during the iterative development process. When we initially launched in September last year…

    ByteNite▲206

    Hi HN, I’m one of the creators of ByteNite (https://bytenite.com). We built it for developers running compute-heavy containerized workloads (AI, ETL, batch jobs) who are frustrated with the limitations of traditional serverless platforms: timeouts, cold starts, orchestration complexity, and limited runtime control. ByteNite is a serverless platform that lets you submit distributed jobs packaged as Docker containers. You define simple or complex fan-out/fan-in logic, set your hardware requirements, and we handle the rest—distributing execution across warm cloud runners (CPUs,…

    Keystone▲125

    We kept hitting the same wall: you clone some arbitrary repo and just want it to run without any configuration work. So we built Keystone, an open source tool that spins up a Modal sandbox, runs Claude Code inside it, and produces a working .devcontainer/ config (Dockerfile, devcontainer.json, test runner) for any git repo. We build on the dev container standard, so the output works with VS Code and GitHub Codespaces out of the box. Main use cases: reproducible dev/CI environments, self-describing repos, and safely sandboxed coding agents. Our goal is to encourage all repos to…

    Hi HN, I've been building Nucleus, a lightweight Linux container runtime focused on two workloads: ephemeral AI-agent sandboxes and declarative NixOS services. It's a single Rust binary, no daemon. It is not a Docker replacement and not a strict subset of Docker either. I dropped the entire image-and-distribution half (no Dockerfile, no layers, no registry, no pull/push, no persistent storage layer) in exchange for going deeper on isolation and reproducibility. The rootfs is either a directory copied into tmpfs (agent mode) or a Nix-built closure mounted read-only (production mode). If…

    I built this because I was always creating machines on GH actions to test builds on different OS, and I wanted a tight CLI that could do it. I always saw Actions as this great resources and ephemeral machines you could do dev work in just were a natural way for me to work, so this grew out of that workflow. I didn't expect it to blow up, so it wasn't 100% finished when I posted it. But it should stabilize pretty quickly. Happy to know what you think and talk about it.

    Hi HN - We've been working on Coasts (“containerized hosts”) to make it so you can run multiple localhost instances, and multiple docker-compose runtimes, across git worktrees on the same computer. Here’s a demo: https://www.youtube.com/watch?v=yRiySdGQZZA. There are also videos in our docs that give a good conceptual overview: https://coasts.dev/docs/learn-coasts-videos. Agents can make code changes in different worktrees in isolation, but it's hard for them to test their changes without multiple localhost runtimes that are isolated and scoped to those…

    I've been working with a partner team to integrate wasm workloads with existing container toolchains with the goal of enabling wasm workloads anywhere, be it on the edge, in kubernetes, or wherever. To that end, this project implements a containerd shim which runs those wasm workloads. It is designed as a library to bring your own host implementation, but also includes an implementation for WASI. Right now the library assumes you are using wasmtime, which is embedded in. It works either standalone (run with containerd directly) or in kubernetes. Kubernetes networking and storage are wired…
