Run WASM in Containerd

I've been working with a partner team to integrate wasm workloads with existing container toolchains with the goal of enabling wasm workloads anywhere, be it on the edge, in kubernetes, or wherever. To that end, this project implements a containerd shim which runs those wasm workloads. It is designed as a library to bring your own host implementation, but also includes an implementation for WASI. Right now the library assumes you are using wasmtime, which is embedded in. It works either standalone (run with containerd directly) or in kubernetes. Kubernetes networking and storage are wired…

Run WASM in Containerd launched on May 2, 2022 with 77 votes, #453 of 2,942 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 4 years on.

In plain words

Run WASM in Containerd is a containerd shim that enables WebAssembly workloads to run alongside traditional containers in edge, Kubernetes, and standalone environments. Built as a library with a WASI implementation and embedded Wasmtime runtime, it allows developers to deploy and manage WebAssembly applications using existing container toolchains. The tool integrates Kubernetes networking and storage, enabling WebAssembly pods to operate seamlessly with native workloads on the same infrastructure and be exposed as services.

  • Sandboxing untrusted code using WebAssemblyFeb 2026 · github.com · ▲76

    Hi everyone, I built a runtime to isolate untrusted code using wasm sandboxes. Basically, it protects your host system from problems that untrusted code can cause. We’ve had a great discussion about sandboxing in Python lately that elaborates a bit more on the problem [1]. In TypeScript, wasm integration is even more natural thanks to the close proximity between both ecosystems. The core is built in Rust. On top of that, I use WASI 0.2 via wasmtime and the component model, along with custom SDKs that keep things as idiomatic as possible. For example, in Python we have a simple decorator:…

    A WebAssembly runtime embedded in Godot game engine projects. Interact with Wasm modules from GDScript. Accessing Wasm modules via GDScript provides the following benefits. - Sandboxed environment allows safely loading zero-trust mods/extensions to a project. - Single target means that Wasm modules can be built from any language e.g. Rust, Go, AssemblyScript and the single binary can be run on all platforms. - Fast execution compared to GDScript allows for offloading compute-heavy operations or running bots/mods/etc. at high FPS. This might be useful for loading mods, bot AI,…

    Hi HN, I’m one of the creators of ByteNite (https://bytenite.com). We built it for developers running compute-heavy containerized workloads (AI, ETL, batch jobs) who are frustrated with the limitations of traditional serverless platforms: timeouts, cold starts, orchestration complexity, and limited runtime control. ByteNite is a serverless platform that lets you submit distributed jobs packaged as Docker containers. You define simple or complex fan-out/fan-in logic, set your hardware requirements, and we handle the rest—distributing execution across warm cloud runners (CPUs,…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
