Launch VM workloads securely and instantaneously, without VMs▲12
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 made a free global VC directory (1,500 firms, no signup)▲6
Hey everyone I wanted to share something I made: vcdir.com - a global, 100% free directory of 1300+ venture capital firms. Most VC databases I found were either outdated, overly complex, or hidden behind a paywall. So I decided to make one that’s: It’s 100% free to browse, no signup or paywall required. It lists 1,300+ VC firms from around the world (and the number keeps growing). Lets you filter by country, continent, investment phase, and market focus Each firm’s page includes basic informations like short description portfolio links, website, contact info, investment focus. Includes…

We built a <60ms, open-source alternative to E2B using RustVMM and KVM▲7
Over the past few months, as we scaled our internal AI Agents, we hit a dead end: Running LLM-generated arbitrary code in Docker is basically running naked on security due to container escape risks. But using full traditional VMs takes minutes to boot and eats too much memory to support high-density concurrency. We loved the developer experience of SaaS sandboxes on the market, but they are closed-source, expensive, and have too high a barrier to entry for self-hosting. So, our team decided to build our own. After months of grinding, using RustVMM and KVM, we built a blazing-fast,…
