OSS WebAssembly Workers Server Compatible with Cloudflare

In plain words

This open-source server runs WebAssembly workers locally, making it compatible with Cloudflare's worker environment. It allows developers to test and run serverless functions written in WebAssembly before deploying to production. The tool is designed for developers who want to build and experiment with WebAssembly-based applications using a Cloudflare-compatible framework.

Workers are an exciting, relatively recent technology to run serverless applications, typically in the Edge. This article covers Wasm Workers Server, an open source project to run workers-based applications : scripts or functions that receive an HTTP request and return an HTTP response. Workers are a way to encapsulate application logic in a modular, self-contained and portable way . Workers started on the browser to run code in a separate thread from the main one . More recently, companies like Deno , Cloudflare , and Vercel have popularized server-side workers on their edge networks thanks to new isolation technologies . It brings the power of serverless close to your users. Some of these…from wasmlabs.dev

  OpenWorkers – Self-hosted Cloudflare workers in RustJan 2026 · openworkers.com · ▲500

  I've been working on this for some time now, starting with vm2, then deno-core for 2 years, and recently rewrote it on rusty_v8 with Claude's help. OpenWorkers lets you run untrusted JS in V8 isolates on your own infrastructure. Same DX as Cloudflare Workers, no vendor lock-in. What works today: fetch, KV, Postgres bindings, S3/R2, cron scheduling, crypto.subtle. Self-hosting is a single docker-compose file + Postgres. Would love feedback on the architecture and what feature you'd want next.

  Run WASM in Containerd2022 · github.com · ▲77

  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…

  Talanoa▲346

  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…

  I 3D scanned the interior of the Great Pyramid at Giza▲1,752

  Hey HN, I 3d scanned the interior of the Great Pyramid &#x2F; Khufu's pyramid for the Giza Project this summer and just finished the guided version to share. Would love feedback and&#x2F;or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to…

  Restfox – Open source lightweight alternative to Postman▲758

  Last time I posted this it didn't garner much interest. There have been lots of improvements and fixes since the last release. Quick list of features: - Workspaces - Tabs - Nested Folders - Lots of context menus - Response history - Plugins - Runs fully in the browser and runs offline if necessary - Chrome and Firefox extension to bypass CORS restrictions - Desktop builds for all platforms - GraphQL support - Import collections exported from Postman and Insomnia - Simple user friendly interface I built this because I love Insomnia but wanted a portable version that I could run in the…

  America – Road Trip Simulator▲663

  APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more. Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.
