Top 16 Rust Wasi Projects

Project mention: IoT Architectures Under Pressure: hosting a portable firmware (Part 3) | dev.to | 2025-05-16
Several WASM runtimes are available to execute our code. In this example, we'll use Wasmer, though other options exist. If we compile AOT (Ahead-of-Time), we don’t even need a runtime at all!
-
InfluxDB
InfluxDB – Built for High-Performance Time Series Workloads. InfluxDB 3 OSS is now GA. Transform, enrich, and act on time series data directly in the database. Automate critical tasks and eliminate the need to move data externally. Download now.
-
The Bytecode Alliance maintains a number of open source WebAssembly projects, including two WebAssembly runtimes (Wasmtime and Wamr), the component model tools, and language-specific tooling like jco for Javascript and componentize-py for Python. Members of the Bytecode Alliance also do substantial work on standards for the W3C.

The WASI systems libraries that define the standard platform for WebAssembly/wasm are Capability-based.
From their first high level goal:
> Define a set of portable, modular, runtime-independent, and WebAssembly-native APIs which can be used by WebAssembly code to interact with the outside world. These APIs preserve the essential sandboxed nature of WebAssembly through a Capability-based API design.

More like, an attempt in the field from 2 years ago
> [Warning] This project is currently not actively maintained.
But there is a library to build containerd shims with which is maintained: https://github.com/containerd/runwasi
Let's just entertain the idea and pretend that this is a notable project and that one would count it as DevOps tooling.

golem
Golem is an open source durable computing platform that makes it easy to build and deploy highly reliable distributed systems. (by golemcloud)
I was super pumped when the Zio creator had a hand in creating this State-Machine-That-Can’t-Crash as a Service, called Golem. I was further excited because they had support for Grain, an OCAML style FP soundly typed language. I could just never find the time/inspiration to play as I still feel trapped in the “all things are AWS” vortex. Yes, I’ve played with & used CloudFlare in production, but… as a AWS Step Functions fan, this seemed like a cool idea. One of these weekends I’ll try again with TypeScript since Grain appears to be no longer an option.

containerd-wasm-shims

spiderlightning
A set of WIT definitions and associated implementations to enable app developers to work at a faster pace and require less knowledge of the environment in which they are executing.

webassembly-tour
⚙️ Take you through a tour of WebAssembly (WASM targets on WASI) with wasmCloud, Krustlet, WAGI, etc. 🌟 Give it a star if you like it.

Project mention: Show HN: Obelisk – a WASM-based deterministic workflow engine | news.ycombinator.com | 2025-04-09
I do agree that the ecosystem is not mature yet, but I was able to generate HTTP activities using LLM on a single shot.
