24 alternatives to Hyper – distributed Firecracker microVM orchestrator written in Elixir
Hey everyone! One of the problems I ran into is that a large part of the VM-provider ecosystem is currently paid closed-source SAAS products with varying degrees of reliability. I wanted an OSS distributed microVM orchestrator and I couldn't find one. Hyper is a distributed FirecrackerVM orchestrator written in Elixir (BEAM), with gRPC support for non-BEAM clients. Hyper is: - Distributed -- it's designed to run across a cluster of bare metal machines, and will automatically connect to other Hyper nodes. - Fast -- it builds COW layers to enable fast, localized COW forking. Cold boots happen…

I 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…

This is a project I made over the weekend. What if when you SSH'd into a machine, instead of giving you a user login, it would provision a new microVM just for you? It's like a little SimCity for VMs. This turned out to be a lot of fun, and I've wanted to make my own custom SSH server for a while now, with its fancy progress bars and color animations. The hardest part was definitely debugging VM setup, boot, and networking though! Compiling the Linux kernel with all the right configs was difficult. For a while I had issues with silent hangs on boot due to lack of available system entropy, on…

Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://github.com/hyperdxio/hyperdx Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously…

Hyperterse▲86Hi HN, I’m Samrith, creator of Hyperterse. Today I’m launching Hyperterse 2.0, a schema-first framework for building MCP servers directly on top of your existing production databases. If you're building AI agents in production, you’ve probably run into agents needing access to structured, reliable data but wiring your business logic to MCP tools is tedious. Most teams end up writing fragile glue code. Or worse, giving agents unsafe, overbroad access. There isn’t a clean, principled way to expose just the right data surface to agents. Hyperterse lets you define a schema over your data and…

Hi HN! We’re Yann, Edouard, and Bastien from Koyeb (https://www.koyeb.com/). We’re building a platform to let you deploy full-stack apps on high-performance hardware around the world, with zero configuration. We provide a “global serverless feeling”, without the hassle of re-writing all your apps or managing k8s complexity [1]. We built Scaleway, a cloud service provider where we designed ARM servers and provided them as cloud servers. During our time there, we saw customers struggle with the same issues while trying to deploy full-stack applications and APIs resiliently. As…

I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx

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…

Hypersplit is like Neal's Infinite Craft but turned upside down. Instead of crafting your way up from the four elements, you start big and go small, down to quarks. It's using GPT-4 to split the words, but a big difference from Infinite Craft is that I can precalculate the possible paths since they are limited (sooner or later you hit a quark or a loop). This means that I can ship it with the whole dictionary locally instead of hitting an LLM every split. While it started with just the splitting, I quickly got the urge to split things faster... which turned the app into the incremental…

Hi HN, we build an open-source operating system extension for orchestrating robot swarms fully decentralized. This first beta version allows you to create fully decentralized robot swarms. The system will set up a wireless mesh network and run a p2p networking stack on top of it, such that nodes can interact with each other through various abstractions using our SDKs (Rust, Python, TypeScript) or a CLI. We hope this is a step toward better inter-robot communication (and a fun project if you have a few Raspberry Pis lying around). Our mesh network is created by B.A.T.M.A.N.-adv and we’ve…

We have built Tarit as a hypervisor built from ground up for running AI agent and RL environments. It is based on rust-vmm and can be used as a replacement for firecracker. Firecracker was built to serve a different need of primarily serverless compute and hence does not have primitives like live snapshots without pausing the VM operations. We also provide a basic orchestrator that handles placement of the microVMs, creating clusters with HA, maintaining a warm pool of VMs, and takes care of setting up networking and monitoring. Our benchmarks on a metal instance shows an acquire VM from…

Hi, over the past few months I've been working on this project: Numax is a small Rust runtime that does three things: it runs WebAssembly modules in a sandbox, has a built-in local key-value store, and syncs everything across nodes with CRDTs and gossip. Basically, you write a wasm module, run it on two machines, and they converge (I hope !). It's a decentralized system... I hope someone finds it interesting! There's a whitepaper I've put a lot into, and I think the code isn't bad either! I believe there's still room in this world for software that's fun and well made, and while building…

Hi HN, I built Ayder — a single-binary, HTTP-native durable event log written in C. The wedge is simple: curl is the client (no JVM, no ZooKeeper, no thick client libs). There’s a 2-minute demo that starts with an unclean SIGKILL, then restarts and verifies offsets + data are still there. Numbers (3-node Raft, real network, sync-majority writes, 64B payload): ~50K msg/s sustained (wrk2 @ 50K req/s), client P99 ~3.46ms. Crash recovery after SIGKILL is ~40–50s with ~8M offsets. Repo link has the video, benchmarks, and quick start. I’m looking for a few early design partners (any…

Hi Everyone, Prashant here from Devtron. With the community’s help and feedback, we built Hyperion - An Opensource tool to observe, deploy, manage & debug Helm Application on Multiple Clusters. We developed Hyperion as a module that comes with Devtron preinstalled or it can be separately installed. While there are pre-existing tools like Kubernetes dashboard, Lens, Octant; Hyperion is focused on helm charts. Some of the features which sets it apart are: - Deploy, manage, observe and Debug Helm charts across multiple clusters. A. Install, Manage Helm charts, Applications across multiple…

Hello, HN community, I'm really excited to show you Open Fire a serverless CI, how does it work? relying on serverless technologies (firecracker) we can spin up a new VM in less than 200 ms running in a more powerful and newest CPU on the market, just change 1 line of code on your GitHub Actions Workflow and you're up and running! You can see our use case, where we implemented Open Fire in the NextJS repo taking down build time from 1 hour 17 minutes to 26 minutes which is a 66 % of improvement without any engineering effort! [1] The value of a CI/CD Pipeline is inversely proportional…
