Show HN: Hyper – distributed Firecracker microVM orchestrator written in Elixir

Hacker News - Thu, 07/09/2026 - 1:10pm

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 within 1s. Filesystem forks take ~50ms. Forked VMs are colocated to take the fast path as much as possible. - Interactive -- like all Elixir applications, if you can connect to the cluster, you can spawn, manage, monitor and interact with VMs live in an `iex` REPL. Or, you can use the gRPC interface if your system isn't on the BEAM. - Yours -- although I developed this primarily for Harmont (which is paid), Hyper is an MIT-licensed project and will remain such. - Self-contained -- all we need is a side-car Postgres instance. - Configurable -- colocation, vmlinux options, etc. can all be customized. - Secure -- everything runs on the BEAM; a single setuid Rust helper performs the few operations that need root, keeping the privileged surface small.

Fair warning: the software is still in active testing and I expect a couple more features to be added soon:

- Automatic cloud provisioning -- when you run out of headroom in your cluster, you should be able to fall back to Latitude/GCP/AWS to provision more compute. - More testing -- I am currently integrating Hyper into harmont.dev and will likely run into some issues. Fuzzing is part of the roadmap. - Better docs -- I spent _some_ time working on the docs, but they're definitely not total nor ideal.

Very open to feedback, critique, and/or contributions. Please open any issues on Github, or feel free to DM/email me.

PS. A couple people asked how this differs from firecracker-containerd and Kata containers. Both of those projects are runtimes for managing VMs on a single node. A fair mental model for Hyper is an amalgam of firecracker-containerd and k8s.

Best Budget Earbuds for 2026: Cheap Wireless Picks

CNET Feed - Thu, 07/09/2026 - 1:01pm
I've tested dozens of inexpensive earbuds to find the best values. These are my current top bargain picks, almost all of which cost less than $100, and some less than $50.
