Products that do what Keystone does
Teach your repo how to run itself
- 1KB
When cloning a repo, we kept hitting the same wall: no Dockerfile, no dev container, no clear path to running it. Asking an agent to fix it directly on your system is risky, as it can clear Docker config, change kernel settings, downgrade packages without warning. Keystone runs the agent inside a Modal sandbox with its own Docker daemon. It iterates until tests pass, then hands you a .devcontainer/ you can just check in. Now your repo knows how to run itself!

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…

Hello HN! We've been working on a new hypervisor https://kwarantine.xyz that can run strongly isolated containers. This is still a WIP, but we wanted to give the community an idea about our approach, its benefits, and various use cases it unlocks. Today, VMs are used to host containers, and make up for the lack of strong security as well as kernel isolation in containers. This work adds this missing security piece in containers. We plan on launching a free private beta soon. Meanwhile, we'd deeply appreciate any feedback, and happy to answer any questions here or on our slack…

I built DevClaw, an OpenClaw plugin that turns each Telegram group into an isolated, autonomous dev team: planner/orchestrator, DEVs, and QA all running on their own. I use it for all my development now. Issues on GitLab/GitHub are the single source of truth, and three things compound to save around 70% on tokens: model tiering (Haiku for typos, Opus for architecture), session reuse across tasks, and token-free scheduling that burns zero LLM calls for orchestration. Please try it and give some feedback. Also keen to hear from anyone running autonomous coding agents, especially what…

Link: https://docs.trysoma.ai/ For the past ~9 months I’ve been building Soma, an open-source AI agent & workflow runtime written in Rust, with a TypeScript SDK (Python coming soon). It’s not a framework; it’s meant to sit underneath whatever agent/tooling code you already write (Vercel AI SDK, LangChain, custom code, etc.). It provides features around your framework + a better DX for building agents. I’ve tried to take a Next.JS model: open-source, good DX, self-deployable. I originally set out to build a vertical back-office/operations product for SMEs. I needed a…

Runbox recreates core container features without relying on existing runtimes or external libraries. It uses namespaces, cgroups v2, and seccomp to create an isolated process environment, with a simple shell for interaction. For future gonna work on adding an interface so external applications can be executed inside Runbox, similar to containers. Github: https://github.com/Sahilb315/runbox Happy to hear feedback or suggestions.

As I've increasingly pursued orchestrated agentic coding - I needed a safe way to run Claude Code in YOLO mode on my mac. I looked at a lot of options including Docker but then came across Lima (Linux for Mac) and this great guide by Chris Hager on how create a dev sandbox for your mac using Lima. This creates an Ubuntu VM, mapped to your dev directory with RW access, port and SSH forwarding, Mise support for language installs and automatic code agent installs. https://www.metachris.dev/2025/11/sandbox-your-ai-dev-tools-... I followed his guide. Got it working on my…

Hi everyone, I'm Vasek (https://x.com/mlejva), the CEO of the company behind this - https://e2b.dev. The company is called E2B. We're an open-source (https://github.com/e2b-dev) devtool that makes it easy to run untrusted AI-generated code in our secure sandboxes. You can think of us as coding runtime for LLMs. You can self host us on GCP (https://github.com/e2b-dev/infra/blob/main/self-host.md) and we're working on AWS, then Azure, and any Linux machine. This repo is one of our open-source projects that we're…

Hey HN, As most of you (I think?), I cannot learn something without having a project, on the side, to implement what I’ve just learned. Recode is the project that I've used to learn Go. It lets you create a development environment in your cloud provider account easily. You can think of it as a desktop version of Gitpod / Coder / GitHub Codespaces less polished and with less features but 100% free and open-source. At the time of writing, it only works with Visual Studio Code and AWS. In order to let you configure your development environments easily, I’ve chosen to use Docker with…
