Devbox – Easy, predictable shells and containers▲515
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).

Devbox – Containers for better dev environments▲116
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…

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…

Building better base images▲38
This project addresses the inefficiencies of traditional Dockerfile-based container builds where each customization layer creates storage bloat through duplicate dependencies from repeated apt-get install commands, network inefficiency from redundant package downloads across different images, and slow iteration cycles requiring full rebuilds of all previous steps. Our solution enables building minimal base images from scratch using debootstrap that precisely include only required components in the initial build, while allowing creation of specialized variants (Java, Kafka, etc.) from these…
