🛠️ sandboxd: Lightweight Dev Sandboxes

In short, sandboxd is trying to provide a minimalist, self-hosted development sandbox solution. As coding agents become more prevalent, providing these AI systems with a secure, isolated environment where they can run and preview code in real-time has become a strict necessity. Its main appeal is bypassing Kubernetes entirely, relying instead on simple commands and Docker to spin up isolated environments complete with preview URLs. The hard part is not just starting a container, but managing the lifecycle of these ephemeral environments at a low cost and integrating them into the automated workflows of AI coding assistants. If you are building coding agents or need dynamic preview environments for a SaaS product, this tool offers a very lightweight alternative. It is essentially filling in a missing piece of infrastructure for autonomous AI programming.
