[CLI Tool] Show HN: Devbox – Containers for clean dev environments I&#x27;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:<p>- Instant setup: `devbox init my-project` and you&#x27;re in a fresh env with `devbox shell`.<p>- Configurable via JSON: Define packages, services, and more in a `devbox.json` file. Share it in your repo for reproducible setups—teammates just run `devbox up`.<p>- Docker-in-Docker by default: Build and run containers inside your env without extra config.<p>- Host-friendly: Edit code directly on your machine; the container handles the runtime.<p>- Templates for quick starts: Built-ins for Python, Node.js, Go, web dev, etc.<p>- Advanced options: Port mapping, env vars, resource limits, and even mounting your dotfiles.<p>It&#x27;s FOSS (MIT license), Linux-focused (Debian&#x2F;Ubuntu, or WSL2 on Windows), and super easy to install: `curl -fsSL <a href="https:&#x2F;&#x2F;devbox.ar0.eu&#x2F;install.sh" rel="nofollow">https:&#x2F;&#x2F;devbox.ar0.eu&#x2F;install.sh</a> | bash`.<p>Check out the launch page and docs at <a href="https:&#x2F;&#x2F;devbox.ar0.eu" rel="nofollow">https:&#x2F;&#x2F;devbox.ar0.eu</a>, or the repo at <a href="https:&#x2F;&#x2F;github.com&#x2F;itzCozi&#x2F;devbox" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;itzCozi&#x2F;devbox</a>. I&#x27;d love some feedback, stars, or contributions to help grow this into a solid community tool!

[Monitoring/Observability] Show HN: Kekkai – a simple, fast file integrity monitoring tool in Go I built a tool called *Kekkai* for file integrity monitoring in production environments. It records file hashes during deployment and later verifies them to detect unauthorized modifications (e.g. from OS command injection or tampering).<p>Why it matters:<p>* Many web apps (PHP, Ruby, Python, etc.) on AWS EC2 need a lightweight way to confirm their code hasn’t been changed. * Traditional approaches that rely on metadata often create false positives. * Kekkai checks only file content, so it reliably detects real changes. * I’ve deployed it to an EC2 PHP application in production, and it’s working smoothly so far.<p>Key points:<p>* *Content-only hashing* (ignores timestamps&#x2F;metadata) * *Symlink protection* (detects swaps&#x2F;changes) * *Secure S3 storage* (deploy servers write-only, app servers read-only) * *Single Go binary* with minimal dependencies<p>Would love feedback from others running apps on EC2 or managing file integrity in production.

[Other] Show HN: Open-source AI data generator (now hosted) Hey HN! A few months ago we shared our AI dataset generator as an open source repo, and the response was incredible (<a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44388093">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=44388093</a>). We got requests from folks who wanted to use it without the hosting overhead, so we created both options: a hosted version (<a href="https:&#x2F;&#x2F;www.metabase.com&#x2F;ai-data-generator" rel="nofollow">https:&#x2F;&#x2F;www.metabase.com&#x2F;ai-data-generator</a> for instant use and the source code fully open (<a href="https:&#x2F;&#x2F;github.com&#x2F;metabase&#x2F;dataset-generator" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;metabase&#x2F;dataset-generator</a>) for anyone who wants to self-host or contribute.<p>Looking forward to seeing how you use it and what you build on top of it!<p>Bonus: The repo now supports multi-provider LLM integration with LiteLLM, thanks to a great contribution from their team.

[Other] Show HN: SSH-hypervisor – like SSH, but each user gets their own microVM This is a project I made over the weekend. What if when you SSH&#x27;d into a machine, instead of giving you a user login, it would provision a new microVM just for you?<p>It&#x27;s like a little SimCity for VMs.<p>This turned out to be a lot of fun, and I&#x27;ve wanted to make my own custom SSH server for a while now, with its fancy progress bars and color animations. The hardest part was definitely debugging VM setup, boot, and networking though! Compiling the Linux kernel with all the right configs was difficult. For a while I had issues with silent hangs on boot due to lack of available system entropy, on Linux &lt;4.19. Anyway, I wrote a bit about my struggles. :D<p>I managed to bundle everything (vmlinux 6.1, firecracker, SSH server, iptables&#x2F;bridge&#x2F;masquerade) into a single, statically-linked binary for x86_64&#x2F;aarch64. It takes the kernel rootfs as a command-line argument.

Perfect for ADHD brains, multitaskers, or anyone who needs a firm nudge to stay on track of things.<p>Clipboard history Access your recent copies without switching apps.<p>URL &amp; text utilities Select any URL in any app to shorten it or generate a QR Code.<p>Media &amp; Meetings controls Manage playback, mute&#x2F;unmute from Microsoft Teams, even when the app is in the background or minimized.<p>Personalization Save custom prompts, dock the &quot;sill&quot; to the top, bottom, left, right, or change its size to reflect your style and needs.<p>All from a single, universal command bar that stays out of your way — no friction, no app switching.<p>Bonus: the app is extensible! It comes with an SDK allowing any app to integrate with WindowSill.<p>Who is it for? Mainly Windows power users, but also anyone looking to boost their productivity with AI-powered text assistance and quick access to useful tools.<p>Try it today for free!
