In plain words
Bottlefire is a development tool that converts Docker images into single-executable microVMs. It enables developers to package containerized applications as lightweight virtual machines that run as standalone binaries. This approach combines the portability of containers with the isolation properties of virtual machines, making it useful for developers who need to distribute self-contained applications across different environments without requiring Docker or other container infrastructure.

Bottlefire turns container images into standalone, zero-dependency Linux executables that bundle Firecracker and launch microVMs automatically. $ curl -fL https://bottlefire.dev/run/ debian:trixie | sh root@container:/# # Sandbox with Landlock $ curl -fL https://bottlefire.dev/run/ debian:trixie | \ landrun --best-effort --unrestricted-network --rox /usr/bin --rox /usr/lib --ro /etc --ro /run --rw /dev/kvm --rw /dev/tty --rwx /tmp sh root@container:/# # Download the executable directly $ curl -fL -o app https://images.bottlefire.dev/ debian:trixie ?arch=linux/amd64 $ file app app: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped $ chmod +x ./app && ./app…from bottlefire.dev

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

Talanoa▲346Hi 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…

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
